Preface

       Farming is no longer a subsidiary occupation. Now with the recent advances in science
and technology, evaluation of crops has become highly scientific. A number of plants have been
thoroughly studied, botanically classified and are being utilized by human being for different
purposes. This booklet describes the types of classification of different crops.

Dr. K.T. Chandy, Agricultural & environmental Education

I. Introduction

         Before going to any agronomic field operations some basic knowledge about the crops
must be acquired. Classification of different agricultural crops is an acceptable product of
scientific studies and is obviously based on well demarcated characteristics.

        A crop is a life grown or harvested for obtaining yield. Several plants are alike with
respect to morphology, anatomy, physiology and requirement of particular type of ecology at
different stages of their growth and development. All these help to generalize similar crop
plants as a class for attaining a better understanding of them. While considering some crops as
a group some exceptions must always be expected.

        Classification is of very much importance for a farmer because he can know very clearly
about each and every crop which will indirectly be helpful in his cash return. The classification
will also be helpful in knowing the type of crop to be grown in the field according to the fertility
status and climate.

        Crops are grouped in several ways namely, according to the range of cultivation. place
of origin, different characters. etc. They are mentioned in detail here.

ll. Classification According to Place of Origin

       A number of crops may be grown anywhere in the world but each crop has its native
place. where its large number of wild relatives are also present. The agro-climatic situation of
the place of origin may provide relevant information about the ideal environment for its
adaptability. The wild relatives or varieties may be used as gene pool for any further
improvement of the crop concerned.

       According to the place of origin the crops are grouped into following categories.

A. Native crops
       These are the crops which are grown within the geographical limits of their origin. Some
crops of Indian origin are: rice, barley, black gram, mustard, castor, sugarcane, cotton, etc.

B. Exotic crops
        These are the crops which are grown beyond or far away from their site of origin. Some
of the crops which are now grown in India, were introduced from other countries are: tobacco,
potato, jute, maize, etc.

III. Botanical or Taxonomic Classification

        According to this classification crops are dealt with under the natural orders or the
families under which they come, in a systematic arrangement. In this classification all the plants
referring to one particular family are grouped together. This classification has certain
advantages in understanding of the morphological characters of any particular family. Following
are some crops grouped into families.

A. Poaceae ( Graminae) or grass family
       These crops are: rice, wheat, maize, barley, oat, sugarcane, napier, sorghum,
paragrass, etc.

B. Papilionaceae (legumes) or pea family

        These are the crops which are grown with the intention of serving the purposes in
addition to obtaining yield to meet a particular purpose. They are further classified on the basis
of the purposes they serve.

1. Catch crops or emergency crops
         These crops are cultivated to 'catch' the forthcoming season. They replace a main crop
that has failed due to biotic or climatic or management hazards. They provide livestock feed at a
difficult time of year, check weed growth, conserve soil, utilize added fertilizer and moisture.
They are generally of short duration, quick growing, fast bulking, harvestable at any time of
their field duration and adaptable to the season, soil and cultural practices. Examples of such
crops are green gram, bajra, black gram, spinach, cowpea. radish, coriander, onion, etc.

2. Restorative crops
        These are the crops which provide a good harvest along with enrichment or restoration
of the soil. They fix atmospheric nitrogen with the help of bacteria found in their root nodules,
shed their leaves during ripening and thus restore soil condition. They are: soyabean, alfalfa,
berseem, green gram, cowpea, blackgram, clover, etc.

3. Exhaustive crops
       These are the crops when sown, exhausts the important nutrients for plant growth
present in the field. They are: sesame, linseed, brinjal, etc.

4. Para crops
       These are the crops which are sown few days or few weeks before the harvesting of
standing mature crop. They are grown on residual moisture without preparatory tillage. The
standing crop and the para-crop becomes simultaneous for a brief period and for the rest of the
duration they remain as single crops. They are: black gram in aus paddy, lathyrus in aman
paddy, and sweet gourd in potato.

5. Smother crops
        These are the crops which are able to suppress the population and growth of weeds by
creating suffocation (reducing movement of air) and obstruction (of the incidential radiation) by
their dense foliage developed due to quick growing ability with heavy tillering or branching. They
are: barley, cowpea, mustard, sweet gourd, etc.

6. Cover crops
        These crops protect the soil surface from erosion (wind, water or both) through their
foliage or root mats. They are: groundnut, lathysus spp., maryel grass, sweet potato, black
gram, para grass, rice, bean, etc.

7. Nurse crops
       These crops help in obtaining nourishment for other crops by provding shade and acting
as climbing sticks. For example, rai in peas, jowar in cowpea, and Glyricidia crotolaria in tea.

       Shade loving plants (sciophytes) such as turmeric, ginger and corn are nourished by tall
crops such as pigeon pea, castor and climbing vegetables such as cucumber, litle gourd,
ashgourd and beans.

8. Guard or barrier crops
       These crops help to protect another crop from wind storms etc. They are: safflower in
gram, and Saccharum munjo around the crop fields situated on the banks of torrential rivers.

9. Brake crops
        These are the crops which are grown to break the continuity of the agro-ecological
situation of the field under multiple cropping systems. The inclusion of such crops in the
cropping system helps to reduce the inoculum of soil-borne harmful biotic agents such as
weeds, pests, pathogens and parasites. It also improves soil conditions for crop growth. The
examples are: Growing potato or oilseeds in continous cereals cropping systems. Rice-wheat,
Rice- Maize, breaks the continuity of a large number of pests due to variations in host ranges
and changing of agrocological situation.

10. Trap crops
       These crops are grown to trap soil borne harmful biotic agents, parasitic weeds like,
orobanche and striga that are trapped by solanaceous and sorghum crops respectively. These
weed seeds germinate when they come in contact with roots of these crops. Therefore, the
destruction of these crops reduces the inoculum of such parasitic weeds. Similarly nematodes
are trapped by some solanaceous crops. On uprooting crop plants, nematodes are pulled out
from the field.

11. Mulch crops
       These crops are grown to conserve soil moisture from base ground by their thick and
dense foliage. They are: cowpea, colocasia, etc.

12. Sod or Turf crops
        These crops belong to the grass family and have sod type tillers with matted foliage and
roots close to the soil surface. They are grown to conserve soil from erosion particularly in non-
arable areas. They are: marvel grass, doob grass (Cynodon dactylon), etc.

13. Cleaning crops
       These are the crops whose agronomic practices make the field clean from weeds and
stubbles. They are: potato, turmeric, groundnut, colocasia, ginger, etc.

14. Fouling crops
        These are the crops whose cultural practices allow the infestation of weeds intensively.
For example, maize, cotton and direct seeded upland rice have low coverage over the ground at
their earlier stages of growth and wider spacing and slow growth at the beginning.

15. Cash crops
       These are the crops grown for sale to earn hard cash. They are: jute, cotton, tobacco,
sugarcane, etc.

16. Ware crops
        These crops are grown for temporary storing as intact in ware houses for future use or
sale. They are in general, fleshy fruits or roots of higher values. For example, potato, carrot,
beet, etc.

17. Truck crops
        These crops are grown to market afresh. These are made available to consumers in
fresh state. They are: lady's finger, spinach, brinial. radish, berseem, etc.

18. Cole crops
        These are cold weather crops belonging to crucifereae family. They are capable of
withstanding considerable frost. The examples of these crops are: cabbage, brussels sprouts,
cauliflower, knolkhol, etc.

19. Silage crops
        These are the crops grown to preserve in pits in a succulent condition by a process of
natural fermentation for feeding livestock during off-seasons. They are: maize, cowpea, bajra,
berseem, jowar, lucerne, etc.
20. Soiling crops
       These crops are grown to harvest in green and fed fresh to livestock in stalls. They are:
berseem, rice-bean, oats, napier grass, etc.

21. Lay crops
        These crops are grown in combination with other crops for immediate or future feeding
to livestocks. The examples are marvel grass + berseem, dinanath grass + cowpea, and
berseem + mustard.

22. Green manuring crops
        These crops are grown to be incorporated afresh into soil to increase the fertility of the
soil. They are: dhaincha, subabool, sunnhemp, lucerne, clyricidia, berseem, etc.

23. Mixed crops
         These consist of two or more crops that are grown simultaneously in the same field
without preserving their identity with respect to field area. Seeds of these crops may be mixed
together before sowing and broadcast irregularly or drilled in rows. They may be harvested
together or separately. For example, pea + rai, towar + cowpea, wheat + mustard, linseed +
toria, gram + safflower, berseem + mustard, and maize + cowpea

24. Intercrops
        These consists of two or more crops that are grown simultaneously in alternate rows in
the same field. The crops are not necessarily sown at exactly the same time and their harvest
time may be quite different but they are usually simultaneously for a significant part of their
growing periods. They are: sesame -black gram, wheat -mustard, pigeon pea + groundnut, rice
+ pigeon pea, sorghum + pigeon pea, and berseem + mustard.

25. Companion crops
        These are the crops within intercrop situations when subsidiary crops are usually of a
shorter duration in a long duration main crop i.e. the main crop gets the company of a short
duration crop for a certain period at the early stages of its growth. The examples are potato,
onion and spinach in autumn sugarcane, lady's finger and amaranthus in spring sugarcane,
radish in potato, and green gram in Napier grass.

26. Parallel crops
       Sometimes two or more crops are grown simultaneously but they do not have inter
competitive effects. They are: maize + cowpea, sorghum + pigeon pea

27. Mono or sole crops
       These crops are grown as pure or solid stands. They are: transplanted rice, jute,
tobacco, oats, etc.

28. Plant crop or first harvest crop of stub crop
        In perennials or multicut crop plants this refers to the first harvest after sowing or
planting of the crop. They are: sugarcane, napier grass, cotton, pigeonpea, berseem, oats, etc.

29. Ratoon crop or stubble crop or coppice
       These are the perennial or multicut crops from which subsequent harvests are taken
from the regrowth of the rootstocks, stubble and stumps, after the firstt harvest. These crops
generally reduce the cost of cultivation. They also reduce the crop cycle, period, produce a
higher yield per unit time and often require less; input. They are: sugarcane, jowar, napier grass,
bajra, berseem, oats, rice, guineagrass, etc.

30. Seed crops
       These are the crops which are grown for seed production. Therefore, these crops
require special care and management to maintain the satisfactory genetic identity and purity of
the crop variety and a healthy crop. 'They are: seed crop of jute, oats, potato, berseem,
cabbage, cowpea, cauliflower, tobacco. etc.

31. Leaf crops
       These crops are grown to harvest leaves to get cash. They are:

       These crops are grown to obtain fife wood or solid fuel as a by-product along with their
economic yield. They are: jute, cotton, sugarcane, mustard, pigeonpea, sesame, etc.

33. Energy crops
       These crops are grown to obtain liquid energy such as ethanol and alcohol. They are:
sugarcane, maize, potato, tapioca, etc.

34. Outer or border crops
       These crops are grown on the border areas of the plot or field of another crop. The
examples are safflower on border of potato, radish on barley border or onion on the border of
cabbage or cauliflower, and mesta in border of sugarcane.

35. Riparian crops
       These crops are grown along irrigation and drainage channels. They protect the soil
from eroding. They are: water bind weed, dhaincha, Pepper wort, bhabar or babui, para grass,
etc.

36. A venue crop
         These are the crops which are grown along the roads and fences. They are: pigeonpea.
glyricidia, sisal, tephrosia, etc.

37. Contour crops
       These are the crops grown on or along the contour lines to protect the land from erosion.
For example, marvel grass, dinanath grass, setaria, anjan grass, etc.

38. Strip crops
        Strip crops are of different types which are described below.

a. Erosion permitting crops
These crops when grown permit erosion, and they require shaping for arable farming. On sloppy
lands they are sown along the slope. They are: maize, toria, bajra, etc.
b. Erosion resisting crops
These crops are grown to check soil erosion. They are grown across the slope of the land.
These crops have good canopy to retard the raindrop velocity. They are: marvel grass,
horsegram, green gram, kidneybean, black gram, etc.
c. Contour strip crops
These crops are grown in strips of suitable width across the slopes (bi or multi directional) on
the level or contour lines alternating with erosion restricting crops particularly where land
shaping is not needed. They are: jowar, groundnut, pigeonpea, marvel grass, etc.
d. Field strip crops
These crops are grown on farm lands in more or less parallel strips across fairly uniform slopes
but not on exact contours. They are: maize, bajra, pigeonpea, green gram, guar, sesame, jowar,
sunnhemp, etc.
e. Wind strip crops
These are tlle crops (tall crops) that are grown with short crops in alternately arranged straight
and long but relatively narrow, parallel strips laid right across the direction of the prevailing wind
regardless of the land contour. They are: tall crops -maize, pigeonpea, jowar, safflower, bajra,
mustard. Short crops -potato, groundnut, green gram, bengal gram, etc.
f. Permanent buffer strip crops
These crops are legumes, grass, bush or shrubs that are grown on a permanent or temporary
basis on the strips that are established to take care of critically steep or highly eroded slopes in
fields under contour strip cropping. They are: subabul, Panicum repens, babul, guinea grass,
Cassia, Prosopis, Glyricidia, cemona grass, etc.

39. Augmenting crops
      These are the crops which are sown to supplement the yield of the main crop. The
example is Japanese mustard with berseem.

40. Alley crops
        These crops are grown mainly to hasten soil fertility restoration. enhance soil productivity
and reduce soil erosion. They are slightly shade loving and non-trailing. For example sweet
potato, black gram, turmeric and ginger in between the rows of Eucalyptus, subabool and
Cassia.
