Goals for forage program Graze as much as possible Spend as little money as possible

Using annuals for forage Pros Double crop High quality Selectivity of species Cons Expense Establishment risk
Developing a forage program Start with tall fescue as base forage Use annuals to fill in production gaps

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

Double-cropping forage Warm-season grass Cool-season annuals
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
What about small grains into tall fescue? Wheat Rye Annual ryegrass Will they improve the winter yield of tall fescue pastures?
Study information Two winter annuals Two dates N Fertilization Wheat Ryegrass Early - mid Sept Late - mid Oct Fall – 0, 60, 90 lb/acre Spring – 80 lb/acre
