                from Europe and are
                now planted and

       Plant Characteristics
•   Growth Type- bunch
•   Texture- Coarse
•   Density- Medium to poor
•   Color- light green
            Uses for Ryegrass
• Uses                • Grain Uses
•   1. Grain 30-40%   •   1. Flour
•   2. Hay            •   2. Alcohol
•   3. Pasture        •   3. Seed
•   4. Cover Crop     •   4. Livestock Feed
                More Uses
•   Temporary cover
•   Nurse grass
•   Pasture
•   Silage and Green chop
•   Erosion Control
•   Wildlife cover feed
• Less subject to disease due to its hardiness
• Ergot is most common disease
• Ergot- A kernel is replaced with black or purple
  fungus called sclerotia
• Leaf spot, barley yellow dwarf virus
• No insect problems are unique to annual ryegrass.
  Grass grub is an important pest of ryegrass.
• In the Southeastern pets ryegrass seedlings are
  attacked by mole crickets and fall armyworms
• Life cycle- Annual or short lived
• Propagation- seed
•   Sun/ Shade- sun to moderate shade
•   Soil- medium to heavy
•   Moisture- medium to wet
•   Good with irrigated farming on well-drained land
• Annual ryegrass is best adapted to cool, moist
• In the milder regions of its adaptation zone, annual
  ryegrass can survive for several years. In the more
  extreme environments, it behaves as an annual.
• Annual ryegrass grows best on fertile, well-drained
  soils, but has a wide range of soil adaptability
         Conditions for Growing
• Annual ryegrass grows best on fertile, well-
  drained soils, but has a wide range of soil
• Annual ryegrass is tolerant of long periods of
  continuous flooding—15 to 20 days when
  temperatures are below 81°F (27°C).
           Special Problems
• Annual--- Difficult to cut
• Can become weedy
        Perennial Vs. Annual
• Perennial requires a dormancy period of
  cool temperatures before it flowers--they
  also flower in late spring
• Annual can be grown in more places than
  Perennial ryegrass.
Where Ryegrass is grown in the
• There are nearly 3 million acres
  of annual ryegrass in the
  United States, with about 90
  percent used for winter pasture
  in the southeast.
• Annual ryegrass produces some
  of the highest quality pasture
  that can be grown in the
  southeastern United States.
      Advantages- Disadvantages
•   Advantages-
•   very good quality possible
•   easy to establish
•   rapid growth rate
•   Disadvantages-
•   poor drought and heat tolerance
•   not well suited to poorly drained soils
Yield (based on 2 harvest seasons)
•   Seeds/ pound: 227,000
•   Seeding rate: 15-20 pounds per acre
•   Seeding date: early spring
•   May survive winter with alfalfa if consistent
    snow cover
