Discription of indivual crop. Asparagus (Asparagus officinalis L) family Liliaceae. Common names. Asparagus (Eng);Asperge (Fr.);Esparrago (Sp); Spargel (Ger.);Asperge (Neth);Lung So Ts‘Lo Sun(China);Asparago(W.I) Varieties. The Washington strains are popular‘Mary Washington produces large shoots and is the standard varieties are rust resistance as well as F-hybrid cultivars and strains that are resistant to Fusarium wilt. Two groups of asparagus varieties evolved based on spear color. The more commercially important of these have a dark green color upon exposure to sunlight and include 'Reading Giant', 'Palmetto', 'Argenteuil', and 'Martha Washington'. The other group includes those producing light green spears such as 'Conover's Colossal' and 'Mammoth White' and 'Martha Washington' Botanical Description. Asparagus is a perennial dioecious monocot, grown for its herbaceous, newly emerged shoot (commonly referred to as a spear). Perennial herb, with fleshy rootstock, up to 1.5 m in height. Root. Tuberous Leaves. Linear, narrow, scale like. Flowers. Male and female flowers are produced on separate plants. Fruit. a berry. Seeds. 1-3 per fruit. Methods of propagation include nursery grown crowns, nursery grown transplants (approximately 12 weeks old), transplants grown from tissue cultural methods, and direct field seeding. The use of tissue culture to propagate plants from vigorous stock plants of the desired sex offers tremendous potential to the asparagus industry. Depending on the row spacing, between 8,000 and 10,000 crowns are required to plant one acre Environmental response. Sandy or silt loams or alluvial soils are often preferred. The suitable pH 6 to 6.7, suitable temperature are 16-24C Cultural practices Traditionally asparagus is a cool season crop with maximum spear production occurring when the average daily temperature is between 65 and 80°F.Seeds are sown 24 hours before use3-4 cm deep in nursery beds in rows 30 cms a part,4-6 cm between plants, the best temperature for germination is 25-30C.The seedlings are transplanted after 240-360 days,row to rows 75-90 cm aprat,50-60 cm between plants in the row, mineral soils receive up to 2,000 pounds/acre of a complete fertilizer, with an N-P-K ratio of 1-2-1 or 1-2-2 recommended. Asparagus seed has high genetic variability. Most plantings employ a spacing of one foot in the row and five feet between the rows for the production of green asparagus. Traditionally, asparagus crowns were planted into 8-10 inch deep. The use of nursery grown seedlings as a means of establishing asparagus plantings is rapidly being accepted as an alternative propagation method due to the high cost of producing, harvesting, and replanting asparagus crowns in the field. Hybrid offspring produce higher yields and show less variability in growth which makes them better adapted Disease and insects. The common disease are. Asparagus Rust, caused by Puccinia asparagi. The plant will be spray with Zineb or maneb. Other leaf and stem disorders include Phoma asparagi Saccardo which produces elongated gray stem lesions surrounded by a reddish brown border and Colletotfichum sp. which produces pale colored cankers covered with black pustules. Other root rots include Phytophthora megasperma, Zopfia rhizophila, and Penicillium martensii. P. martensii is evident on crowns by extensive blue-green color of fruiting bodies at the time they are dug and removed from storage. Another foliar disease that contributes to losses in asparagus in warm, humid environments is Cercospora blight, caused by Cercospora asparagi Sacc. The common insect is Asparagus beetle (Crioceris aspargi) Growth and harvesting. The young shoots or ‗spears‘ are harvested when they reach a height of 10-15 cm, this may be 400-600 days from the establishment of young seed .Harvesting period is 30-60 days. Yield 2.5-4.0 t/ha, these should be replanted every 3-5 years .Plant are mainly cross pollinated. Up to 500kg/ha of seed may be produced. After harvesting it needs cooling 1-3CWhite asparagus kept about 0-2Cin high humidity will keep spears in good condition up to 21days.

Many claim it is an aphrodisiac Future research Genetically engineered food is created by taking the DNA from one organism and inserting it into another. The process passes on certain characteristics to plants and animals. The resulting organism is called "transgenic." This modification of gene material is not possible with traditional selective breeding. Genetically engineered asparagus plants have been regenerated following Agrobacterium-mediated gene transfer. The process based on microprojectile bombardment and direct DNA uptake into protoplasts. The transgenic line show low vigour and poor yield. The nutritional values of transgenic and parental genome was similar .The result show relationship of integration of genetic engineering technology into breeding programmes and safety evaluation of transgenic crops In asparagus the genetic engineering is used to develop new varieties having more nutriton and resistanct to diseases. A concerted effort between breeders and plant health specialists must be maintained and supported to improve genetic resistance to AV-II, purple spot, Phytophthora spear rot, and Cercospora blight. Given the perennial nature of the crop, evaluations require long term-support from private and public sectors. Beans (Snap and Lima). Snap or kidney beans (Phaseolus vulgaris) and Lima beans (Phaseolus lunatus L). It is two main types of cultivars. a) Dwarf or bush cultivars which are daylength neutral, early maturing, 20-60 cm in height, with lateral and terminal inflorescence and determinate growth. b) Climbing or pole cultivars, with indeterminate growth up to 3m in height, normally supported, both daylength neutral and short daylength types.

(Gur) It is resistant to drought .It is grown as a forage and a green manure cop.It is a rich source of Vitamin A, iron and Vitamin C.It need well drain sandy loam soil.About 12kg of seeds will be sufficient to sow one hectare.Sowing is done in rows 60cm apart and . Varieties The varieties Pusa Sadabahar;Pusa Navbahar and Pusa Mausmi. Yield The yield of green pods varies from 5,000 to 6,000 kg per hectare, yield of seed crop is about 1,000 kg per hectare. Cow pea (Vigna slinensis Savi)(Lobia) The common varieties are Yard Long .It requiere 30-50 kg of nitrogen,56 to 78 kg of phosphate and 56-78kg of potash per hectare.Seed in a row 60-75 cm apart and seeds within the row are 15-25cm apart.The high yielding varieties are Pusa Phalguni, Pus Barsati and Pusa Dofasli (IARI).Pusa Phalguni is spring/summer varieties ,Pusa Barsati is rain resistant and Pusa Dofasli is day neutral varieties.It yield is 8,000 to 10,000 kg of green vegetable Hyacinth beans (Dolichos lablab (Rox) & L) (sem) It is highly drought resistant and Pusa early Prolific is an improved variety Future Released the first great northern beans with four genes for rust and two genes for BCMV and BCMN virus resistance. This is a very significant accomplishment. These bean germplasm lines known as BelMiNeb-RMR-8, -9, -10, -11, -12, and -13, are the first and only great northern bean in the world with four genes (Ur-3, -4, -6, and -11) for resistance to the hyper variable rust pathogen. In addition these bean lines have two genes (the dominant I gene and the recessive bc-3) for resistance BCMV and BCMNV resistance, which makes these lines resistant to all known strains of the rust and BCMV and BCMNV. Cabbage (Brassica oleracea L.var,capitata ) It is the most important member of the Cruciferae or mustard family Cabbage goes by many names like Band gobhi, karam kalla,bandha gohbi and patta gobhi .It contains vitamin A, B, and C, it helps in preventing constipation, increases appetite, speed up digestion and useful for patients of diabetes. Cultivars. Chieftan, Earliest, Eclipse Drumhead,Glory of Enkhuizen,Golden Acre,Wakefield,Large blood red,Mammoth Rock Red,Pusa Drumhead Savoy and September. Climate. It loses much of its delicate flavour when grown in hot and dry atmosphere .Head formation is more likely to occour at temperature 24°C.A range of 5°C variation between day and night temperature appears to be necessary for adequate head development. .Most cultivars are daylength neutral and flower initiation depends mainly on the temperature regime which they are grown. Temperature below 10°C induce early flowering. Cultural practices Earthing up done about 5 to 6 weeks from the time of transplanting , the crop will be ready for harvest in 3 to 4 months time .Deficiency of trace elements such as boron and molybdenum may cause physiological disease .The head may be harvested in 70-90 days depending on cultivar and characteristic Soil and its preparations. It is grown in great variety of soils ranging from light sand to heavy loam or clay. Sowing The seed are sown in well prepared seed bed and seedlings when four to six week old and become a few inches high are transplanted in the field in rows at 30-60 cm from each other .About 600 to 700 grams of seed are enough for planting one hectare to give a plant population of 30,000 plant /hac. The range of soil temperature for good seed germination is 13-15°C Seeds are sown in rows five centimetre apart and about 1 cm deep .Head size can be regulated by adjustment of the planting density Varieties There are five important groups of cabbage. The varieties of Drumhead group have large, flat and fairly solid heads. Heads of the Danish Ballhead group are of medium size and very solid .The Savoy group has finely crumpled leaves but is not of much commercial use. The Red cabbage group is characterised by its deep purplish colour. The outstanding varieties existing in the country are Pride ,Golden Acre, Golden Ball, Drumhead, Pusa Drumhead, Late Drumhead, Glory of Enkuien and Copenhagen Market. Manuring Application of superphosphate at 200 to 300 kilogram and ammonium sulphate at 200 to 300 kilogram and 250 kilograms of potash per hectare is needed Planting When seedling are about 1½ month old and grown up to 10-15cm.Early varieties like Pride and Golden Acre kept at space about 40cm from plant to plant and 60cm in rows .The late varieties of Drumhead type may be spaced 45 cm apart from plant to plant and 75 cm apart in rows. Irrigation. The constant level of soil and water should be maintained during the growing to avoid a check to growth and development. A shortage of water may lead to cracking of the head. The effective root zone is approximately 60cm. Yield The yield of cabbage is about 30-45 tons per hectare. Marketing Ripe and firm cabbage can be stored at 0°C to 1.7°C with moderate humidity. Insect and pest. Aphis brassicae (Cabbage aphid),Crocidolomia binsotalis Zeller (Cabbage moth),Hellula spp.(Yellow buterflies),Meloidogye spp. (Root-knot nematodes), Phyllotretd spp.(Flea Beetles),(Curtis) diamond-back moth,Spodoptera littoralis ,(cutworm, click beetle), Alternaria brassica (Alternaria blight),Cercopsopra brassicicola P.Henn.(Cercospora Leaf spot), Leptosphaeria maculans (Blck leg),Peronospora parasities (downy mildew),Plasmodiophora brassica (Clubb rot),Xanthomonas campestris (Black rot) Nutritional value It provide 22 calories per 100g edible portion , and is a good source of vitamin B and calcium. Future various strains of Bt are used to control spruce budworms and gypsy moths in forests, cabbage. Carrot (Daucus carota var.sativa ) Carrot belongs to the family umbellifereae and locally called Gajar. It have high carotene content (precursor of vitamin A), it is an excellent source of vitamin B and vitamin C. Climate. It require a temperature of 15 °C to 20°C for its development Higher temperatures help in the production of shorter and thicker root and lower temperatures produce longer ad selender roots. Soil It can grow from sandy loam to clay loam, lighter soils are preferred .The optimum pH will be between 6.0 to 7.0. The farmyard manure needed about 10-12 tonnes. Sowing. The ridges are 45 cm apart or on flat surface. Seeds are mixed with sand and are dropped in the shallow furrows made on the crest of the ridges, covered lightly with earth and soil formed around the seeds. The depth of sowing will be about 1 to 1.2cm. Varieties. Carrot varieties can be classified into two groups, ie desi or Asiatic types and European types .The former are marked by their large size, dark colour, and sweet taste .However the latter are preferred due to the smooth surface, thin core ,better shape and being less fibrous in nature. The European varieties of carrot are calssified in to three groups. ―Chantaney‖ is short, stump rooted, square shouldered and smooth with change colour; ―Nantes‖ is narrower, cylindrical, rounded at top and base of root with small core, deep orange colours and good quality, others are long rooted thin and tapering .There are various colours of different varieties being white, yellowish orange, and shade of purple .On late crops varieties like Nantes and Scarlet Horn are best Danvers Imperator belogs to the group having log roots, fairly thin, tapering from rounded shoulder to tip.Variety Pusa Kesar, is a selection between the Asiatic and European types , its seed can be produced in plains.Gold pak,Hi-pak hybrid,Carousel,trophy,and spartan sweet. Botanical description An erect biennial, normally grown as an annual ,20-100cm in height. Roots: the main or tap root becomes swollen and thickened and varies in shape and size, normally orange or red in colour. Stems: Solid, condensed at the proximal part of the root. Leaves: Alternate 2-3 pinnate, segments divided, petiole normally long , often sheathed at the base. Inflorescence: Compound umbels, 3-7 cm in diameters, borne on a much branched stalk. Flowers: Normally white or pink, small; sepal 5, petals 5, ovary hairy. Fruit: Oblong-ovoid, 3-4 m in length. Seed: contain essential oil. Optimum pH is in the region of 6.0 to 6.5.The crop is fairly sensitive to temperature, high soil temperatures tend to encourage the production of short roots and may also adversely affect germination .Colour of the roots may also be affected, pale yellow roots being produced as a result soil temperatures in excess of 25°C, root tissue may become reduced. And b-carotene content may be decreased. The optimum air temperature range is 16- 24°C.Dry soil conditions are likely to cause cracking of the roots and tend to favour the development of the long roots. Short daylengths may contribute to a reduction in the b- carotene content of the roots. Cultural practice Seeds are sown at a depth of 1-2 cm in soils cultivated to a depth of 20-25cm.Seeds are sown in drills 30-40 cm apart and seedlings initially thinned when 5-8cm high, to 5-8 cm apart depending on the vigour of the cultivar, seed requirement is approximately 5- 6kg/ha.Potassium is often required in the form of an additional surface dressing. Manuring. 25 tonnes of organic matter is essential for one hectare. It require 80Kg of N,60Kg P 2O 5 and 60Kg K2O per hectare .Half of the amount of N should be applied along with phosphorus and potassium before sowing. Half the amount of N should be applied along with phosphorus and potassium before sowing. Diseases. Meloidogyne spp(Root-knot nematode), Albugo candida (white rust),Alternaria dauci (Leaf spot or blight), cercospora carotae (leaf spot),Erwinia carotovaora (Bacterial soft rot. Harvesting. Roots may be harvested 70 to 80 days from sowing , depending on the size required and cultivars. Harvest is taken up when the roots attain a diameter of 2.5 to 4cm.At room temperature it can store only four days. For prolonged storage cold storage at temperature of 0°C to 4.5°C relative humidity of 93% to 98%.Temperature near 0 ºC will reduce not only sprouting but also the development of a bitter flavour, ethylene production and pathogenic activity.

Future. The existence of "antifreeze proteins" (AFPs) has been known since the late 60s (2), and have since been identified in many organisms that have evolved resistance to freezing temperatures, including bacteria, fungi, fish, insects, and plants (3). AFPs— technically called thermal hysteresis proteins— prevent freezing damage to cellular structures by slowing or stopping the formation of ice crystals inside a cell. Since the 1991 failure, researchers have continued experimenting with various antifreeze genes in an attempt to improve frost resistance in plants, but with very limited success (4). Recent experiments using an AFP identified in carrots have shown some modest success (5). References (1) Hightower R, Baden C, Penzes E, Lund P, and Dunsmuir P. 1991.

Sweet corn (Zea mays L.var.saccharata Sturt. ) It is belong to family Gramineae. Common names. Sweet corn, Maize, Mealies ,Corn, Mais Sucre (Fr.) Maiz Dulce (Spain), Zukermais (Ger).It contain Diploid chromosome nuimber :2n=20. It is grown both in tropical and subtropical areas.It is annual usually with single stem, up to 4m in height.Proper roots are formed from the nodes above the surface, thickened, often pigmented and often photosynthetic, stem is 3 feet high, with diameter of 4cm contain many `nodes and inter nodes, bud formed at an axils of the lower nodes may form tillers. Leaves are alternate , the lower sheath enclosing the internodes, surfaces glabrous or pubescent, linear- laneolate, acuminate 30-150 cm X 5.15 cm across, stomata more numerous on lower epidermis up to 5 mm in length, auricles mostly poorly develped. Flower are monoecious, unisexual, male and femalte inflorescences borne on the same plants.Male flowers terminal panicles termed tassels, up to 40 cm in length, paired spikelets bnorne in severaql rows, 8-13 mm in length, each spikelet has 2 glumes lodicules, 3 stamens, 2 lobed anterns and rudinentary gynaecium. Female flowers: Normally 2 ears, which are modified spikes , each brqch has very short internodes which bear modified leaves forming husks or leaf sheaths , which overlap the ear, the central axis is the cob, bearning paired paired spikelets enclosing 2 florets, the lower of which is sterile, the upper floret is pistallate, many time with rudimentary stamesn, pistil with single basal overy , up to 45 cm in length , which is recepitve to pollen throught length. Environmental responses. It requires medium loams which is well drain , with high organic content, the suitable pH is 5.5-6.8. The optimum seed germination temperature is 30-32 ºC.Its growth is maximum at 20-24 ºC, above 35 ºC fertilization is affected due to pollen sterility and desiccation of the husk tip.High temperature affect on the rate of conversion of sugars to polysaccharides such as starch and effect on the quality of grain.Tillering is encourgaed by diurnal tempeature variation.Flowers need 800-1200 mm per annum precipitation.High temperature delay in maturity and are liable to produce more tillers.Crop is sensitive to daylength variation. Cultural practices. Seeds are sownin rows 60-9- cm apart, 30-45 cm between the plants in the rows, this gives 30,000-35,000 plants/hac.Seeds are mostly sown at the depth ofg 2-3cm.Seeds are required 10-20kg/ha, depenidng upon the plant spacing and seed size.It have shallow root system so regualr irrigation is required .Adequate irrigation is linked with length , weight and diameter of the ears.It requires enough NPK supplies.Nitrogen application effects on the plant population and spacing of plants, ear length, plant height and weight of stover.From growing to sowing it takes nearly 65-95 days, it also depends on cultivars and environmental factors.Its yields is normally 2 cobs per plant, producing 7-15 t/hac depending on planting density and cultivars.An average seed yield of 1000kg/hac .At the time of harvest the kernels should be cream-yellow and firm, kernels are sweeter than cobs with fully developed apical kernels.At the time of harvest rapid cooling is needed to prevent the sucrose being converted to starch by enzyme action .It should be store at 21ºC with variation of 1-2 ºC, relative humidity of 90-95%, with tempertaure at 1-4 ºC it can be store up to 8 days. Nutritional values. The protein content is 1.9% to 3.5%, the seeds are rich in phosphate, potassium, thiamine and vitamin A and beta carotene . Cucumbers.

It requires well drained sandy loams, with pH of 6.0 –6.8 are suitable, some varities can tolerate temperature up to 30 º C, although the suitable temperature are 15-20ºC.High temperature often result in premature flowering, stunted leaf growth and bitter tasting leaves, high temperature area , some cultivars do not form solid heads, they tend to flower precociously and seed without forming the normal number of rosette leaves, some time due to high temperatures , not readily form flowering stem they tend to flower precociously and seed without forming the noramla number of rosette leaves. For seeds the optimum germination temperature is 25 ºC above this temperature, germination percentage falls rapidly due to inhibiton of gaseous diffusion and consequent shortage of oxygen. Gibberellic acid of gaseous diffuseion and consequent shortage of oxygen.Gibberellic acid (GA3) has been found to overcome dormancy induced by high temperature.High temperature with mositure the seeds viability is rapidly lost.Daylenth variation not show any effect on the development. Cultural practice Propagation is from seed which germinates in 4-5 days from sowing, about 25-30 cm apart, about 0.75 kg of seed are required per hectare to give planting density of 200,000 plants/ha. Sowing Seeds are sown in rows 15 to 25 cm apart, seed rate is 2½ kg per hectare. Fertilizer. Usually 10-15 tonnes of farmyard manure and fetilisers to supply 85kg of nitrogen and 60 kg each of potash and phosphorus per hectare are applied. Irrigation. It is require frequent intervals at transplanting and until the seedlings are established.Dry conditions are likely to induce premature flowering . Harvesting Most heading cultivars mature within 60-85 days from transplnating but the loose leaf types may be ready for harvesting within 35-50 days from planting As soon as plants attain acceptable size cutting is done in the morning and the harvest immediately sent to the market. Yield The yield per hectare is 10,000 to 12,000 kg in case of head lettuce, open leaf types generally give comparatively high yield. Premature flowering may be reduced by light shading and regular irrigtion.Most cultivars are usually completely self-pollinated . A seed yield of approximately 120 kg/hac be expected..At temperatures of 0-3 ºC , heads may remain in good condition for up to 14 days at relative humidity of 90-95%, weight loss may be up to 15% Diseases.

Botanical Description Diploid chromosome number 2n=16. A biennial herb, normally grown for its bulb as an annual and only carried forward into asecond year when seeds are required, fruit a capsule, splitting longitudinally Environmental response It require alluyvial or sandy loams .Adequate nitrogen and potash is required but excess nitrogen delay bulb formation.Phosphate is required to promote early leaf development. The suitable pH is 5.8-6.8 , suitable temperature for the bulb formation is 18-25C.flowers rarely form at high temperatures since a cool period is required after bulb formation for the inititation of the inflorescence and flower stalk. It is possible that the change from vegetative growth to bulb formation, which is stimulated bytemperature variation independent of day length, a related to the production of an auxin or hormones which inhibits leaf formation the food produced being diverted to the development of bulb.It requires 14-16 hours daylight for bulb formation.In which poungency of the odour and flavour develped due to formation of n-propyl disulphide when tissues are cut or injured Cultural practice Seeds are normally sown in containers and transplanted to prepared beds after about 45- 60 days when seedlings are 8-12cm in height.They may be planted in a rows 30-38 cm a parat with 8-12cm height.Onionseeds will germinate best at 45 and 85 º F, the plant will grow best between 55 to 75ºF Climate. The plant requires relatively cool weather and abundance of moistuyre in its early stages but stands considerable heat and ripens best in a dry weather.Long days are reqwuired for efficient bulb formation. Soil A rich friable and well manured soil is prefered.Heavier soils do not promote good bulb formation, it require neutral soil.the soil should be worked to a loose fine condition.It is grown in alluvial, clay and sandy soils. Varieties Onion are very sensitive to their photoperiodic requirement, the varities are different on the basis of short day and long day.The varities are Pusa Red, Pusa Ratnar, early Grano (IARI), Patna Red (Sabour),Punjab selection N-53 is a Kharif onion variety. Sowing. About 8 kg seeds per hectare are sown, when the seedlings attain a height of 12cm, they are planted in well prepared and highly manured land at a spacing of 15 to 20 X 10 cm.Planting is done shallow, about 2 to 3 cm deep and the land is then immediately irrigated, the seed rate is about 20 to 25 kg per hectare is required. Manuring. Besides a basal dose of about 15 to 20 tonnes of farmyard manure per hectare, a side dressing of 150kg of ammonium sulphate, 175 kg of superphosphate and 130 kg of potassium sulphate before planting and top dressing of another 150 kg of ammonium sulphate in early stage of growth is benefical. Irrigation Irrigation is necessary for the bulb development, hence irrigation should be restiricted to a minimum in the later stage and stopped when leaves start to wither. Weeding The land should be kept absoluted free of weeds. Growth period and harvesting. Bulb mature within 100-140 days from sowing, depending upon the cultivar.It can give up to 10t/ha Harvesting Onion are tend to mature at the advent of summer.The top will fall over due to shrivelling of the neck.For good storage, the seed stalks emerging should be cut as soon as tshey come out. The bulbs are lifted after the leaves have completley withered and are hung in a dry ventilated place.Immature soft and thick mecked bulbs should be sold out and others used for storage if need be, cold storage is possible at the temperature of 0 to 1ºC with relative humidity of 64 %.. The chemical maleic hydrazide has been found effective in the inhibiton of sprouting. Pest and disease. Ditylenchus disaci (Kuhn),Hylemya antiqua (Meig), Alternaria porri, Cercospora duddiae welles (Cercospora leaf spot), Colletotrichum dematium and fusarius oxysporjum, Pink root caused by soil borne fungi, Pyrenochaeta terrestis and fusarium sp. Neck rot (Botrytis sp), onion smut (Urocytis cepulae), and Downy mildew (Peronospora destructor).Onion thrips and onion Maggots are effect on yield. Yield. The yield varies widely from 14,000 to 25,000 kg per hectare. Nutritional values ,per 100g edible portion Bulb contains 87ml water, 48 calories,1.5g protein,11g carbohydrates,0.5g fibre,30mg calcium ,0.5 mg iron, 0.04mg thiamine, 0.02 mg riboflavin and 6mg ascorbic acid. Peas (Pisum sativum L) The peas are annual, tendril-climbing plants belonging to the Leguminosae family. Two alternative species are sometimes recognized:pisum arvense L-the field pea, and pisum sativum L.var.macrocarpon ser-the sugar pea and var.humile poir-the early dearf pea. Peas are leguminous vegetables.It is a rich source of protein.The plant are capable of utilising atmospheric nitrogen through the nitrogen fixing bacteria found in the nodules of their roots.It is a good source of Vitamin A, B and C. Varieties Peas may be divided into two types , smooth-seeded and wrinkled-seeded. India and Sri Lanka : Alderman, Arkel, Asauji, Bonneville, Early giant, Early tion, Sylvia, Telephone, Thomas Laxton.

An annual herb, with variable habits.Flowers : axillary, 2-3 in raceme, Corolla normally white 1.2-1.6 cm in length, staminal tube grooved, style flattened, stigma terminal.Fruits: pods with short stalks, straight or curved 4-15 cm x 1.5-2.5 cm, 2-10 seeds/poos, endocarp present in most cultivars, exvept those of Sugar Pea. Seeds: round or angled, smooth or wrinkled, green, grey or brown, rarely mottled, approximate weight of 100 seeds= 15-25 g, germination hypogeal.The peas require 60-75 days for maturity. Environmental response. Most cultivar require 13-18 ºC while the high temperature affect pollination. Seeds have a minimum soil temperature requirement of about 10ºC, with pH of 6.0-7.0.Planting distances are normally 30-60 cm between rows, with 6-10 cm between plants in row. Seed requirement is 50-75 kg/ha.Irrigation is particularly important at the flowering stage. Soil It can grow from light sandy loams to heavy clay. Yields are higher on heavier types such as silt loams and calys.It is advisable that to inoculate the soil with the pea nodule bacteria culture particularly on land not previously cropped with leguminours plants. The culture material material which is obtainable from some important agricultural instituions and research centres is emulsified in a small quantitiy of 10% sugar or gur solution and splashed over the seeds heaped on a tarpaulin and mix throughly. The moistend seed is then spread out to dry under shade and then sown. Seeds and sowing The seeds are sown in rows about half a meter aprat and on raised beds of convenient sizes usually 1 to 1.5 meters wide and beds is about 2.5 cm deep.Seed rate is about 50 to 60 kg per hectare .pH of soil will be 5.5-6.5. Poor soil prepartion results in uneven germination and the pea sdo not mature uniformly.This is particularly disadvangeous for processing. Varieties. Peas are divided in to sections according to the seed surface, height, earliness and edibility. .Early varieties, Marrow fat, american wonder, Thomas Laxton, Sutton‘s Early Giant,P-8,T-19 is a mid-season, wrinkled, medium tall type Early Badger, Bonnevillea .The high yielding varieties are : Early December, GC-195 (Gwalior), Boach selection (Solan-HP), Midseason-Lincoin, Bonnevillea, Early Giant, N.P.29 (Plate 14), Pusa- vipasha (IARI), Banarasi seeet, T-56, GC-66, GC-141,GC-468,GC-477, GC-245,GC-31. The selected cultivars of peas are: Alderman, Dark seeded perfection,dark skin perfection, freezer 69, Freezonian, Frosty, giant Stride, Greater Progress, Green Arrow, Lincoln, Little Marvel, Perfected Freezer 60, Progress Strains, Sparkle. Ferilizer 20-25 tonnes per acre of FYM is beneficialSuper phosphate at the rate of 350 to 400 kg and potassium sulphate or muriate of potash about 100kg per hectare may be applied at the time of final preparation of land before sowing.A dressing of ammonium sulphate at 200 to 300kg per hectare applied at the time of pod formation will be benefical. Harvesting. If harvesting is dealy the conversion of sugar into starch the quality deteriorates. The pods and immature seeds may be harvested 60-80 days from sowing , the seeds require up to 140 days to brcome fully mature.Yields of up to 7t/hac of fresh pods have been recorded.The protein cotent of immature seeds varies form 3.1-7.2% , that of young pods 2.6-3.1% and mature seeds about 22%. Yield. Early varities yield about 10,000 kg of green pods while medium and tall varieties yield up to 12,000 per hectare Storage A temperature of 0.0ºC and a relative humidity of 85-90 percent will keep peas for about 2 weeks Insects and diseases. The diseases are root rot, Fusarium wilt, Aschochyta blight, mosaic, bacterial blight, downy mildew, and powdery mildew.The insects are pea aphid, thrips, spider mite, seed corn maggot and pea weevil.These are control by malathion or nicotine sulphate. Peppers (Capsicum annuum and Capsicum frutescens) It belong to the family Solanaceae or nightshade .The garden paper is unrelated to the vine that produces black pepper (piper nigrum).Green pepper are comparatively expensive to produce because of plants, fertilizers and cultural and labour requirement..Peppers are drought resistant mean temperature at blossom-setting time ranging from 65 to 80ºC Cultivars Of the several groups of peppers grown, there are two general calsses: 1) those which produce mild or sweet freuits called sweet peppers and 2) those which bear pungent or hot fruits better known as hot peppers.Generally the sweet cultivars are harvested at the mature green stage, while the hot cultivars are harvested when at the mature red stage, except for the wax types which are picked when yellow.

Botanical description Diploid chromosome number (Tetraploid) : 2n=48, Diploid and triploid are also cultivated It is short-lived perennial herb, grown as an annual, producign swollen underground stem tubers when mature , 0.3-1 in height. Fruit: a small, globose, purple-green or yellow-green poisonour berry, 1.5-2cm in diameter, containing many seeds often more than 300 per fruit. Tubers which should Soil Well-drained, fertile soils with pH in the region of 5.2-6.0 are necessary for the production of adequate crops a low soil pH is likely to reduce the incidence of Scab(Streptomyces scabies).It require temperatre 16-20 ºC .It require 500-750 mm of rain fall for the optimum growth.The flworing period has been found tobe a critical phase of growh at which to apply irigation, the requirement for irrigation is reduced after this period.A high light intensity and high temperature level for tuberization . Cultural requiremet. Cultivation to a depth of 25 cm is normally reqauyired with organic masterial and fertilizers incorporated in the soil befor planting.Tubers whichshould be certified to be free from diseases such as virus, are either planted whole or cut into setts, each set having one or more dormant buds or eye.dormancy, which may last for up to 80-90 days after harvesting may be overcome by dipping the tubers ina 1 part per million solution of gibberellic acid for 5 minutes or by reating them with thiourea, ethyulen chlorhydrin, or potassioun thiocyanate. The sprouted tubers are planted 10-15 cm deep in shallow trenches spaced 75-100 cm apart 20-25 cm between plants, the planting distance should br related to the cultivar virour and climatic conditions.tuber planting rte varies with the size of the tuber or sett and may be 1000-1500 kg/hac. Sowing Potatoes seeds should be disinfected before planting.Captan,maneb,Polyram,zineb or maneb plus zinc ion may be used . Seed rate varies from 1,250 to 1,500 kg of tubers per hectare.Plant spacing is 30 cm a part and the depth of sowing isabout 7cm .The distance between ridges is kept at 45 to 60cm Fertilizer. It needs about 15,000kg of bulky manure per hectare a month before planting .Ammonium sulphate and superphosphate at 320kg and 550 kg per hectare Irrigation It is given at a frequency of 10 days Yield. The average yield is around 25,000 kg per hectare, but yields up to 60,000 kg are expected. Pest and diseases. Agrotis ipsilon (Cutworm),Aphis gossypii Glover,Epilachna philippinensis dieke (Leaf Beetle),Epitrix parvula F (Flea Beetle), and Heliothis armigera (Bollworm, corn Earworm),Pthorimaea operculella (Gnorimoschemas operculella) (leaf minor),Alternaria solani (Early blight), Erwinia atroseptica (Black leg),Erwina carotovora Bergey (Soft rot),leafroll virus, mold mosaci virus an rugose maosaic virus.Early blight caused by Alternaria solani, Leaf blight ,Associated with Phytophthora infesttns,Mosaic Leaf Roll, Scab,Ring Rot,Black leg, and Black Scurf caused by Pellicularia filmentosa . Insects: Colorado potato beetle, potato leaf beetle,potato leaf hopper,potato aphid, potto tuberworms, and potato tuberworms. Harvesting. It can store at 2.5ºC to 4.5ºC at relative humidity of 80-90%.Cold storage is he most effective means of mainting tubers in good conditon, the optimum conditons are a temperature range of 2.2to 3.3ºC and relative humidity of 75-80%.Temperature belwo 0ºC are liable to cause internal tissue breakdown due to chilling injhury.Sprouting in store may be prvented by applying suppressants such as maleic hydrazide, and methyl- alpha naphtalene acetic acid .The yield of tuber may be affected by storage temtment, low storge temperature are likely to result low crop yeids .After low temperature storge, tubers should be kept at a temperature of about 15ºC about 14 days befor planting to encourage the breaking of the dormancy period.

Sowing. The seeds 20-30kg per acre are suggested.sowing in rows spaced at 30 to 40 cm apart.It require pH 6 to 7. Fertilizer. The frmyard manure of about 25 tonnes per acre give good results. A top dressing of 80 to 120kg of nitrate of soda or ammonium sulphate per hectare benefits the crop.14-16% phosphorus,and 3-5% potassium. Irrigation Irrigtion immediately after sowing, watering once in 8 to 10 days is required. Diseases. Dumping off, Mosaic commonly known as blight, or yellow, is caused by the cucumber mosaic virus.Downy Mildew caused by Peronospora effusa , Fusarium Wilt caused by Fusarium solani, Curly-top, Heterosporium leaf spot, aphid (Myzus persieae), spinach leaf miner (Pegomyia hyoseyami), other insects like seed corn maggots, grasshopers, and flea beetles Harvesting. The crop is ready for cutting in 6 to 8 weeks after sowing, then the produce should be kept cool at temperature 0-0ºC and relative humidity of 90 to 95 %. Yield. The yields varies from 8,000 to 14,000 kg per hectare. Sweet potato (Ipomoea batatas Poir ) (Sakarkand) Soil. Deep loams and sandy soils are considered best.In very richand caly soils and under heavy irrigtion, the vines produce lantk vegetative growth and give reduced yield. Varieties There are many vrieties which are calssified according to colour of the rind of the tuber and texture of the flesh.Pusa Safed, Pusa Lal and Pusa Sunehri are improved varieties. Philippines: Batanes, BNAS 51,Centennial, Georgia Red, Goldrush, Heartgold,Julian, Seedling 47. Hawii: HPSA-3, Kona B,McBryde, Nancy Hall, Onolena, Puerto rico, Tantalus. Multiregional: Apache, Don Juan, Mameya, Mississippi, Nemagold, Porto Rico, Red velvet Botanical description Tuber structure: complex, fusiform to globular, smooth or ridged, 8-30cm in length: tuber surface white, yellow, orange, red, purple or brown, flesh white, yellow, orange, red or purple. Fruit: capsule glabrous or hirsute, 5-8mm indiameter, containing 1-4 fertile seeds. Planting. The spacing for field planting is 60 X 30 cm. The central central part of the ―sett‖ (30cm long vine) is pressed into moist soil leaving the ends exposed.The setts strike root in seven to ten days.About 50,000to 65,000 setts are required per hectare. Most cultivars mature in 80-200 days from planting, one plant may prouduce 40-50 tubers, weighing from 100 g to 1kg.Yields of 8-12t/hac. Seed production Since the crop is vegetatively propagated.Seeds are normally set only in daylengthsshorter than 13.5 hours. Fertilizer It need pH 5.6-6.6 is alow encourage growth. A planting density of 20,000 to 30,000 cuttings/hac used. It require large quantiiees of nitrogen , potash and phosphorus.Besides 10 to 15 tonnes of bulky manure, about 300 kg of mixed fertlisers are needed per hectare. Irrigation About 10-20 irrigations are needed for the crop in about 100 days. Harvesting The leaves turn pale and yellow and soil shows cracks when the crop is ready to be lifted, the mature tuber are more brittle and juice dreis up quickly, vines are first cut and removed and the tubers are lifted after week. Tomato (Lycospersicon esculentum Mill) (Tamatar) The ripe tomato contains 93 to 94% water, it is a good source of vitamin A and B and an excellent source of vitamin C. Botanical description. A variable heb, up to 2m in height. Roots: Vigorous tap root with extensive fibrous roots. Stems: Solid, hariy, rooting at nodes. Leaves: Spirally arranged, 15-30cm x 10-25 cm, petiole 3-6 cm long, often divided into unevenly shaped pinnar, mainly oval, irregualrly toothed, often with small pinnae between larger leaflets. Flowers: In cymes (trussess) or 4-12, borne opposite or between leaves, about 2 cm in diameter.calyx tube short, hairy, sepals persistent, petals usually 6, up to 1 cm in length, yellow, reflexed when mature, stamens 6, anthers bright yellow. Fruits: a fleshy berry with 2-9 loculi, orange, yellow or red whebn ripe, usually round, smooth or furrowed,2-15 cm in diameter. Seeds: numerous, kidney-or pear-shaped, hairy, light brown, 3-5 mm x 2-4 mm, approximate weight of 1000 seeds =2.5g. Environmental response. Well drained, fertile soils with a good moisture-retaining capacity and high level of organic material are preferable many cultivars are tolerant to a wide range of soil condition.Slightly acid conditon, with pH of 5.8-6.8 are considered suitable.Low temperatures retard the growth of seedlings and the absorption of minerals may also be affected.High temperature above 27ºC are likely to induce pollen sterility and high night tempeature adversley affect flower inititation.Optimum temperature is maintain by 21- 27ºC temperature , this is partly related to the maintenance of an adequate carbohydrates/nitrogen balance in the plant and the funcitoning of the auxin regulatory system in promiting both growth and fruit setting.16-20ºC are considered adequate for most of the cultivars, below 13ºC pollination and fertilization are severly affected. High temperatures, combined with low relative humidity furit quality, particularly the colour of the fruits.Spray of gibberellic acid, at the rate of 50 parts per million, applied at the fruit setting stage have been found to increase the ascorbic acid content of the fruits in some areas. Excessive rainfall and high relative humidityh can be harmful to the tomatoes.Modern tomato cultivars have been selected and fbred for daylenght neutrality and are not generally affected byt being grown in short dyalenght conditons. High light intensitie have been found to induce a high level of ascorbic acid production in the ripening fruits. Cultural requirements. The seed requirement is approximately 0.5kg/ha for the density of 20,000-30,000 plants/he. Plants may be established in single row 70-90 cm apart, 30-38cm between plants or in double rows 45-60cm apart, 45cm between plants in the row 75-90 cm between the double rows.For single cultivation ridges should be 75-90cm apart with 45- 60cm between plants Climate. During warm and sunny weather, the fruit ripemsn best for yield, colour and quality. Seed and sowing. Seeds are treated with fungicide before it is sown.Two of the better treatments are captan and thiram, thgorougly dusted on the seed at the rate of 1 level teaspoonful per pound of seed. As 400 to 425 gm of seed will produce sufficient plants for one hectare.Tomato can be grown all the year around Soil and its preparation. Tomato is grown on a variety of soils, from sandy loam to heavy loam is the best.Before plantation of seed , about 20 to 25 tonnes of farmyard manure is applied per hectare , and 112kg of phosphorus in the form of superphosphate is benefical.about 300 to 335 kg per hectare of ammonium sulphate applied as a top dressing in three split, the first dose of about 112kg to be applied when the plants have set after transplanting, the secod dose of eqwual quantity in the second month and third dose after fruit set.

Tomoto is frist sown in seedbed and seedlings are later transplanted in the field when they are about 12 to 15 cm in height, in rows 75 cm apart and at a distance of 60cm between plants.The fertile soils, the distance is increased to 90cm x 75 cm Irrigation and weed control In hot weather, irigation should be givben every week or then days but during winter, the crop should be eatered sparingly Stalked or trellised tomtatoes. Pruning and trimming helps in early ripening less injury from fungal disease and cleaner fruits, Stalkes about 3 or 4 cm in diameter and 2 meters high are the most common support.Mulching with staw or other liter helps reduce blossom end rot by retaining mositure. Harvesting. Fruit can normally be harvested from indeterminate cultivars 70-100 days from transplanting , determinate cultivars may begin fruiting after 60 days, depend upn the environmental coditons. The stage of harvesting depends upon the distance of market and time to be taken in marketing the produce.Tomatoes for local market should be picked when fully ripe and for distant markets when they are turning pink, for far off and distant markets, they may be harvested even earlier. Pest and diseases. Scapteriscus vicinus R.and Heb (Mole cricket), Spodoptera littoralis (cutoworm), Sylepta derogata (cotton leaf roller ), Tetraychaus truncatus ebara (redi spider mite), Alternaria solani (Early blight), Cladosporium fulvum (Leaf mould), Colletotrichum nigrum (Anthracnose), Corynespora cassicola (target leaf spot) ,fusarium oxysproum (Fusarium wilt), Leveillula taurica (powdery mildew), Pseudomonals solancearum (Bactierail wilt), Sclerotium rolfsii (Wilt and fruit rot), Septoria lycopersici (leaf spot),Xanthomonas vesicatora (Bacterial leaf and fruit spot), and cuciber mosaic virus.Fusarium wilt caused by the fungus fusarium oxysporium f.lycopersici, bactieral wilt caused byt Pseudomonas solancearum , early blight produced by Alternaria solani, nailhead spot caused by Alternaria tomato, septoria leaf spot caused by sepotorial lycopersici, root knot caused by nematode, gray leaf spot caused by stemphylium solani, damping off caused by Pythium, Phytophthora and Botrytis,bacterial cranker caused by Corynebacterisum michiganense, blossom-end rot, sunscald, virus disease, growth cracks Yield. The yield per hectare varies gratly but on an average it ranges from 15 to 25 tonnes per hectare. A single, well grown plant may produce 3 to 5 kg or more of fruit. Seed production Most cutivars are seolf-pollinated although in some tropical conditons up to 25% of cross-pollination may occur.Crops for seed fproduction should be checked for plant habit, earliness, fruit shape, colour and size.the ripe fruits are picked and seed extracted. The gelationous layer around each seed is removed by fermenting the seeds in plastic containers for up to 3 dyas.The seed is removed from the slurry by sieves, it is then washed and air driedThe dry seed is rubbed to separate individual seeds. An average seed yield is 100kg/ha. Storage. Tomatoes store well at a temperature range of 12 ºC to 15ºC.Mature green tomatoes can be kept for about 25 to 30 days at 10ºC to 15 ºC for more than 10 days at a temperature as low as 4.5ºC, with relative humidity at 85 to 90%.High temperature prevent the production of lycopene, the red pigemtn responsible for fruit colour.Normal ripening temperature are 18-24 ºC Nutritenional values. 100g of edible portion contains 93ml water, provide 21 carories, 1.0g protein, 0.2g fat, 4g carbohydrate, 0.6g fibre, 10mg calcium, 25mg phosphours, 0.6mg iron, 450ug contain beta carotene,0.06mg thiamine,0.04mg riboflavin,0.6mg niacin and 26mg ascorbic acid. Future work. Make improvement in early cultivars, development of diseases-resistant strains and improvement of plant type and fruit quality. Cauliflower (Brassica oleracea L.var.botrytis) Its local name is Phul kibhi, It contains good amount of vitamin B and fari amount of protein incomparsion to toer leafy vegetables. Botanical description. A biennial, normally grown as an annualThe edible portion, or curd, consisist of a mass of abortive flowers on thick hypertrophied brances which are produced at the top of a short thick stem.Leaves long and ellipitical, the outer ones are often broken and folded or tied over the curd to prevent Sun scalad weight of 1000 sees =3g. Envrionmental response There are three main groups, calssed according to curd development: those which will form curds and flower in hot weather conditon at fariley low elevations: the medium type which require cool coditons and the late maturing tyopes which take a long time to develop curds and aslso require relatively low temperatures, below 25ºC, for curd development.At high temperature encourgaes the production of samll, hard curd, optimum soil ph is in the region of 6.0 to 7.0, acid soils are sometimes treated with lime or limestone if the pH value is too low. Climate It is sensitive to heat.If the temperature is high when the curds are maturing the curds will become yellowish, ricy or leafy.The plant are less hardy than cabbage. Soil Rich, heavy loam soils with good drainage are ideal for caulliflowr growing.Light soils need to be supplied with plenty of organic matter. Fertilizer Under some condition, boron must be included to prvent browning and obtain higher yields.Top-dressing of nitrogen will be necessary to maintain steady growth.Since cauliflower has a high demand of magnesium, boron and molybdenum, deficiencies may occour and can be corrected by the application of dolomitic limestone, borax or ammonium moyybdate at the recommended rates.Soil acidity is also lonked with the availability of these elements, particularly magnesium and molybdenum. Varities. There are usuallyfour main group of cauliflowe-early, mid season, late and imported kinds.In seed trade many more groups are given such as kuari, katki, aghani, poosi, maghi all depneding upon the month of their avbailability.Early varities are sown from end of May to middle of June, mid season from early July to end of July and late varities from end of July to end of August.For late sowings, improted varieties such as, Snowball etc prefered.The late snowball varieites can be sown up to the end of October.Thecrop readyto harvest in 3-4 month. Some of the recommended varieties which yeidl heavily are: Early –Pusa Katki, synthetic II, Synthetic III, Kunwari, Hissar I, Kalianpur Medium, Late-Dania ,Snowball-16 (EC 12013), Sel.I,EC-12012,SC-I,SC-2 and Ki Sowing The cauliflower is first sown in seed beds and seedlings are transplanted afterward.The seed requirement for the early crop varies from 600 to 750gm and for late crop 375 to 400gm per hectare.Curd of cauliflowers can be harvested 60-120 days from transplanting depending on the cultivart growth, early, medium and late maturing cultivars are availbel in many areas. Planting. The seedlings, when six weeks old are transpolanted at a distance of 60cm x 45cm or 60cm x 60cm in well prepard and fgertilized soils.The seedlings are transplanted on ridges. Approximately 500g seed is required to establish a crop at a de3nsity of 18,000 plants/hac. Cultural practices. Clean tillage is required to prevent competition by weeds.Regykar urrugatuib at 10-15 days interval is necessary.Cauliflower curds mst not be allowed to ―Sun exposuyre ― otherwise they become yellow and leaves of the plants should be drawn up and tied together at the tips when the head formation starts or a caulifflower leaf may be placed over the head to protect it from sun.Exvessive irrigation may lead to curd decay.Seeds are not normally produced exvept during dry periods at altitude over 1500 m.flowers are cross pollinated.220 kg/ha of seed have been produced locally.Plants selected on curd characters and leaf protection should be retained for seed and grown in isolation. Pest and diseases. Agrotis spp(cutworms), Aphis spp(Aphids), Crocidolomia binotalis Zeller (cabbage moth),Meloidogyne spp (root knot nematode), Phyllotreta spp (flea beetles), Pieris canidia sparman (cabbage butterfly), Plutella xylostella (Diamond back moth), spodopotera littoralis (cut worm), Alternaria brassicae (Alternaria blight), Erysiphe polygoni (powdery mildew), Leptosphaeria maculans (blackleg),Pythium ultimm (Damping-off), Thanatephorus cucumeris (stem rot) Harvesting. Solid and compact curds are necessary for quality caulifflower along with the white colour.They should be harvested when the curd has acquired the proper size and is at the right statge of maturity.All the curds do not develop uniformly at the same time.the curds should not be allowed to over mature.the harvesting may be done either in the evening or early morning. Yield The yield of cauliflower curds varies from 20 to 30 tonnes per hectare.The early crop usually yields low as compared to mid-season or late crops.The heads can be stored for about a month in cold storage at 0ºC with 85 to 90% relative humidity. Preparation for market and storage. The leaves should be green and turgid and are normaly trimmed to leave 2-3cm projnecting to protect the heads dueing handling.Heads should be graded accoridng to size, colour, quality and cultivar , shortly after harvesting. Field heat may be removed by cooling with water, followed by wrapping in heads may be stored for periods up to 28 days.At 4ºC the storage life is about 7 days.For transport , heads may be packed in nets or crates, firm packing will reduce loss due to brusing. Nutritional values 100g of edible portion contains: 87ml water, 43 calories,4.0 g protein, 0.3g Fat, 6g carbohydrate, 1.5g fiber, 100mg califcium, 2.0mg phosphours, 600mg iron,0.15mg thaiamine,0.20mg riboflacvin, 1.0 mg niacin , and 80mg ascorbic acid.

Envrionemtal response: It require well drained soils, sandy-loamy , but with good moisture-retaining properties are generally considered suitable.A pH suitble from 5.5-6.8 is considered suitable. High temperature of 25-30ºC is good for growth an ddevelopment The egg plant is well adapted to both wet and dry season cultivation but exvessive rainfall will check both vegetative growth and flower formation.Elevations of up to 1200m are satisfactory for cultivtion and most cultivars appear to be daylength neutral. Cultural requirements. Seeds, often soaked in water for 24 hours to hasten germination are sown in containers or seedbeds protected from exvessive sun, rain and wind .Seedling are transplanted when 8 - 10cm in height to ridges or raised beds.Rows are 75-90 cm apart with plants 60-70cm apart in the row on between ridges 50-60cm x 50-60cm each weay.For ridge planting 75- 90 cm between ridges, 50-60cn between plants.The seed requiremtn is 800g/hac for population of 10,000-30,000 plants/hac.In areas whrere Bacterial Wilt is common the plant are grafted on the resistant rootstocks of Solanum species. Seeds and sowing . About 1kg of seed is required for planting one hectare.When seedlings have grown to height of 10-12 cm they are planted out, rows 60 to 90cm apart and about 45cm from plant to plant in the row.Tall types require larger spacing Fertilizer. It requires 50 tonnes per hectare of farmyard maure, 250 kg ammonium sulpahte, 300kg super phospahte and 100kg of potassium sulphate , mix with the soil at the time of final field preparation.Another 250kg of ammonium sulphate is given as a top dressing in two split doses with irrigation, when plants have established in the field and secondly in flowering and fruitng stage. Irrigation. It depend upon the locality and type of soil, in hot weather irrigation may be from 4-5 days anf once a fortnight in winter , irrigation should be more fequent to keep the soil moist. Harvest. Fruit set may be increased by the appliction of plant growth regulations such as 2,4 -D to both seeds and flowering plants.Fruit may be harvested from 80-120 days from transplanting, depending on the characteristics of the cultivar and rate of growth, most cultivars continure fruit production into a secod year.Harvesting of fruit sas they become mature will extend the fruiting period of mature plants. The fruit should be harvested when they are still tender, but after they have attained a good size and hen the surface is britht and glossy, Yield The yield is about 20,000 to 24,000 kg per hectare and about 2kg per plant. Storage. The fruit keep well for 2 to 3 days in winter, In storge at 7ºC to 10ºC at a relative humidity of 85-90% keeps the fruits for over a week.. Egg plantws are sold for distant asw well as for local markets.Attraftive packaging and proper handling are necessary for maximum returns, retail preference appears to be for small, uniform-size fruits. Seeds. The flowers are both self- and cross-pollinated and since up to 20% of cross pollination may occur, 500m is a satisfactory isolation distance between cultivars.The seed may be extracted from the dry ripended fruits or by a wet extraction mathods.the seeds are sun dried.An average seed yeidl is 100-150 kg/ha.

Garlic (Allium sativum) It have medicinal values. It has compound bulbs contaming 10 to 16 cloves enclosed by a thin membraneous sheath.It have spacing 15 x 8 cm spacing.The seed stalks are removed as they emege, harvest is done when the plants die down.the yield varies 7,500 to 15,000 kg per hectare. Cultivars. Many selections and cloes are in cultivation, mainly distinguished by the number of cloves produced per bulb-this may vary from 16-50 and by the size of individual. Ther are early (White or Mexican ) and late (Pink or Italian) cultivars. Botanical discription. An erect herb, biennial, normally grown as an annual, up to 60cm in height. Roots: adventitious. Bulb: with condensed flattened stem, enclsoed by apery scvale leaves; bulb seprarate in to samll separate bulbs or cloves formed from axillary buds, each with outer protective shealthing scales, single cloves consist ofa thinckened storage leaf sheath and central bud. Leaveslades, linear, flattened, solid, up to 2.5 cm across. Flower: in umbels, borne on smooth, round , solid scpate, variable in number on slender prdicles, perianth approxciaktey 4 mm in length, pink. Seed requirements. True seeds is seldom used in the prfopagation of garlic.Cloves and tup sets are used, but cloves are more common.Since the size of the cloves determines the number of planting units per pound, a sample of the stock to be use dor seed should be taken and average numbher of cloves per pound detemined.Usually 800 to 1000 pounds of cloves are needed to plant an acre. Soil and cultural requirements. Garlic thrives best on a fraiable sandy loam well supplied with organic matter. Seed is prepared by breaking ythe mother bulbs aprat, so that the cloves of which they are composed become individual unit.these units are planted singly 3-6 inches apart, according to cultivart, in rows 12 to 16 inches apart.The larger polants produce larger bulbs. Environmental conditions. It require realtively high temperature up to 30ºCare required for optimum bulb development but cooler conditons in the early stages favour vegtetative growth. Flower initiation does not appear to be directly linked with low temperature some clones do not flower. Excvessive humidity and rainfall are needed for vegetative growth and bulb formation In most areas, elevations from 500-2000 m provide suitable growting conditons particularly during dry preioids. Log days favour bulb developmentsthe toatl yield depends on the amount of vegetative growth made before bulbing begains. Cultural practivces. The cloves are separated in to single segments , planting space in rows 30-40 cm apart, with 10-15cm between plants inb the row.The cloves should preferabley palntedtowards the end of wet season. About 500-700 kg of cloves are required to plant one hectare. Pest and diseases. Ditylenchus dipsaci (stem and bulb nematodes), Thrips tabaci.(onion thrips),Alternaria porri (puple blotch), Peronospora destructor (Downy mildew), Puccinia alli (Rust) Sclerotum cepivorum (white rot or bulbrot) Harvesting. The bulb should be mature 90-120 days from planting, when the leaves turn brown and dry out. Leaves required for flavouring can be cut before they become mature. Yield It produce 5-10 t/ha, depending on thecultivar characteristic. Seed production. Plants do not normally produce fetile flowers. Market and storage. Bulbs may be stored at 0ºC for up to 150 days or at 25-30 ºC for up to 90 dyas.At both temperatures, the relative humidity should be less than 70% . Nutritional values. Manily use das a condiment for fglavcouring meat and fish, or in salads.the characteristic flavour of grlic id due to the production of allein and diallyl dislphide. 100 g of edible fruit contains: 66ml water, 122 caloreis, 7.0g protein, 0.3g fat, 25 g carbohydrates, 1.1 g fibre, 26mg calcium, 109mg phosphours, 1.2mg iron, 0.23mg thiamine, 0.08 mg riboflavin, 0.4mg niacin and 7mg ascorbic acid. Soya bean (Glycine max(l.)Merrill Common names are : Soya bean, soja (Fr), Soja (SP), Sojabohn (Ger), Sojoaboon (Neth), Too-a-leu-ang (Thai), wonfg tau(China) Cultivars. Two main groups ofcultivrs occour:1) with terminal bud developing in to and inflorescence. 2) Cultivars with indeterminate growth and no terminal inflorescnece cultivars select for specific regions . Cultivars are vary from 75-170 days for maturity, they also vary gratly in soil and climatic adaptation colour, quality, flavor and ease of cooking.The cultivrs are: Hahto, Disoy, Zogun, Green Giant, kim and Kanrich Botanical description An annual herb, 20-180 cm in height. Roots: tap roots may ectend t6o 2 m , laterals mainly develop to 60cm, root nodules globose, sometimes lobed, Stems: hairy, normally erect, bracnhing, sometimes twining or climbing Leaves: alternate, trifoliate, pubescent, petioles long and narrow, leaflets ovate or lanceolate 3-10cm x 2-6cm Flowers: small, white or lilac in clusters of 3-15 borne on short axillary reacvemes, calyx lobes acuminate often with purple tinge, ovary hairy, stamens free or joined at base, stigma cpitate. Fruits: pods hairy, borne in clusters on short stalks in groupo of 5-15 , yellow grey, brown or balck, the black seeded cultivars are normally suited to tropicla cultivations, pods 3-7 cm x 1cm, dehiscent, generally 2-3 seeded. Seeds: globose or flattened, yellow, green, brown or balck, mature beans contains a higher percentage of protein than any other pulse and most other food crops average weitght of 100 seeds = 50-70g germination epigeal. Environmental conditons. Due to selection and hybridixation soya bean cultivars have been produced which are adapted to a wide range of soil and climatic coditons. Sandy or clay loam favours it, pH about 5.7-6.2 are suitable, but a specific strain of Rhizobium japonicum, the nitrogen fixing bacteria which lives symbioticvally on the root system, is necessary for optimum growth and inoculation may be in the root system, is necessary for optimum growth and inoculation may be necessary where the crop has prviously been grown. The suitable temperatures are below 38ºC and rainfall above 500mm per annum, is needed for its growth. The soyabean is sensitive to photoperiod since it is ashort day plant and daylenght approxikately 12 hours are necessary for most cultivarsMany establish cultivars need dark period of from 10-14 hours and are unlikely to flower unless these reauirement are met. Cultural practice Propragation and planting, Seeds aresown 2-4 cm deep on the flat or on ridges 45-60 cm apart, seeds 8-12 cm apart in the row, depending on the virour of the cultivar.Seed required is 40-50 kg/hac. Irrigation. Not normally required since the seeds are usualy sown during a wet period, the plant becoming well established before the dry season begins. Irrigation may be necessary if the soil water deficit increases to a point where growth is likely to be retarded. Nutrient requirements. Phosphours and potassium are generally applied before sowing, acid soils may require dressings of lime if calcium is deficient. Growth and havestet. Pods are harvested 80-120 days from sowing, depending on the characteristics of the cultivar and degree of maturity required. Yield. Very varibale, from 800-1500 kg/hacv of dried seed. Seed prodcution. Soya beans ar self-fertile and are normally self pollinated.Cross –pollination by insects occurs to a limited extent. Average seed yields are 1000 kg/hac, but double this yield can be achieved under good cultural conditons. Pest and diseases. Epicauta spp (Blister beetles), Etiella zinckenella (Pod boreer),Lasperyresia glycinivorella (soya bean pod boreer), Ophiomyia phaseoli (Bean fly), Cerecospora diaizu (frog eye leaf spot), Diaporthe phaseolorum Meloidogyne spp (root knot nematode), Pseudomonas glycinea (Bacterial blight), Xanthomaonas phaseoli (bacterial blight), yellow mosaic virus and yellow mottle. Nutritonal values. 100g of edible seeds produces: 9ml water, provide 405 caloreis, contain 33.7g protein, 17.9g fat, 33g carbohydrtes, 4.7g fibre, 183 mg calcium, 545 mg phosphorus, 6.1.mg iron, 55ug beta carotene, 0.71mg thiamine, 0.25mg riboflavin, 2.0 mg niacin.

Summer sqwuashes Commonly C.pepo, are eaten in the immature stages when the rind is verysoft.White bush scallop, early prolific straightneck, senca buitterbar hybrid, seneca prolic , zucchini hybrid, striata, caserta, cocozelle and zucchini are popular cultivars.All these are bush type. Winter squashes . Winter squahses, utilized when the fruits are mature, have hard rinds and store well.The members of this group usually have flesh of mild flavor and fie tedture, and suitable for baking .Cultivars of winter squash are included in all the species of cucurbita, these includes Envrionmental response. Plants require a fairy high temperature above 25-27ºC, during the growing period with farily low humidity, but some cultivars are also tolerant of realtively cool conditions. Soils with a high organic content are preferable and some culitvars are tolerant to slightly acid soils like pH 5.5-6.8, but pumpkins are tolerant toa wide range of soil conditons. Most cultivars are relatively insensitve to daylength. Climate. It is a warm season crop. The seeds geminate best at a temperature of 27ºC Cultural requirements. Propagation and planting. Seeds are sown 2-4 cm deep in prepareed holes or beds, they are 20 cm apart with 60-100 cm between plants, trailing types 1-3 m apart.Seeds are sown in containers and transplanted when 8-10 cm in heiht. Seed required is 5-7kg/ha for density of 5000 plants/ha. Irrigation. It require regular intervals. Nutritonal requiements. NPK is applied before sowing or planting dollowed by aplication of nitrogenous fetilizer or liquid manure at intervals of 10-14 days until the fruit develop Soil The sutitable soil are sandy loam and silt loams . Varieties. There are two tyupes, one with light green colour and other with dark green in colour. Sowing Raised beds of 1 to 1.5 metre wide with irrigation furrows between them .3-4 seeds are sown per pit about 1cm deep then give irrigation water. Seeds germinate in 6-14 days.A second cropo raised with cotton, maize and such other crops. Manuring 10-15 tons of farmyard manure is needed with tope dressing with 150 kg of ammonium sulphate application are made when plants start to trail and at the start of fruiting. Irrigation crop should not be irrigated immediately after germination .The first irritation is givben when the plants start growing well along with the top dressing of ammonium sulpahte well before flowering.Later in dry weather, the crop is irigated once in 4-5 days. Pest and diseases. Aphis spp (Aphid), Aulacophora sp (Red pumpking beetle), Copa occidentalis (Leaf beetle), Dactus ciliathus (Fruit fly), Halticus tribitalis (Flea hopper), Lagria villosa (Leaf beetle), Choanephora cucurbitarium (wet rot), Pseudoperonospora cubensis (Downy mildew) Growth and harvesting. Fruit is harvested 80-140 days from sowing or planting.The optimum harvesting stage is before the seeds ripen and when the skin of the fruit begmins to harden. Yields. Are 3-6 fruits/plants, individual fruits may weitgh 2-5 kg. Seed production Cultvars are local type s of C.Maxima are all cross-compatiable with eafch other and with C.Moschata, the isllation distance should therfore be 1000 m.the rop is largely cross- pollinated, by insets. Harvest The plants start producing fruit when they start forming runnin shoots.These fruit ar walnut size and it is desireable to remove them as othersise further production of fruit is delayed.The second flush fruit are harvested at one-fourth the normal size hwen they wil be tender.Hairy and soft seeded.The fruits should not be pulled off the vines so as to prvent damage to the plant.The fruits are removed to the shade after harvest and are packed in basket and marketed. Yield. The yield varies from 7,500 to 11,500 kg per hectare. Market and storage. The fruti is store at 10-16ºC at a relative humidityof about 60% decay occours at high humidites.Many cultivrs have storage life of 60-80 days.Before sby exposing the fruits to a tempeaaature of 16-21ºC for 7 days. Storage. The vegetable keeps well for 3-4 days wih frequent splashing of water and when kept under shade.
