Presentation Transcript

  1. Using Annuals for Forage Production Gary Bates Professor Plant Sciences

  2. Goals for forage program • Graze as much as possible • Spend as little money as possible

  3. Yield of tall fescue Ball and co-workers. 1996. Southern Forages

  4. Annual Forage Species Warm-season sudex pearl millet crabgrass teffgrass Cool-season wheat annual ryegrass rye turnips

  5. Using annuals for forage • Pros • Double crop • High quality • Selectivity of species • Cons • Expense • Establishment risk

  6. Developing a forage program • Start with tall fescue as base forage • Use annuals to fill in production gaps

  7. warm-season grass tall fescue Ball and co-workers. 1996. Southern Forages

  8. Warm Season Annual Grasses

  9. Warm-season forage • 10-25% of pasture • Grazing during June, July, August • Allows tall fescue to be rested

  10. Yield of tall fescue Ball and co-workers. 1996. Southern Forages

  11. Season yield of cool-season annuals Daniel and co-workers. 1983. NC State Univ. Crop Research Report No. 91.

  12. Cool-season annuals Warm-season grass Double-cropping forage

  13. Key Principles • Use tall fescue as base forage species • Red and white clover • Stockpile in fall • Devote 10-25% of land to a warm-season production • Bermudagrass • Summer annuals • Use cool-season annuals to follow warm-season program

  14. Will they improve the winter yield of tall fescue pastures? What about small grains into tall fescue? • Wheat • Rye • Annual ryegrass

  15. Wheat Ryegrass Early - mid Sept Late - mid Oct Fall – 0, 60, 90 lb/acre Spring – 80 lb/acre Study information • Two winter annuals • Two dates • N Fertilization

  16. Effect of overseeding and fall N rate on fall fescue yield Harvested 12/15/01 G. Bates. 2001. Knoxville Experiment Station.

  17. Effect of overseeding and fall N rate on spring fescue yield All plots received 80 lb N/acre in late February Havested 3/15/02 G. Bates. 2001. Knoxville Experiment Station.

  18. Key Principles • Use tall fescue as base forage species • Red and white clover • Stockpile in fall • Devote 10-25% of land to a warm-season production • Bermudagrass • Summer annuals • Use cool-season annuals to follow warm-season program
