Forage Selection and Seeding Rates
Choosing the proper forage species for a pure stand or a mixture depends on how it adapts to various soil characteristics and how it is to be used. Table 1.8-3 gives characteristics of the more important peren- nial forages grown in Pennsylvania.
Highest-quality forage is achieved when all species and varieties are harvested at the recommended stages of maturity. A spread in forage harvest season can be obtained by a proper choice of species and varieties with the desired differences in maturation time. Relative maturities for the first cutting of several species and varieties are given in Table 1.8-4. Actual dates vary from year to year and location to location. When making up mixtures, choose species and varieties that mature at approximately the same time.
Suggested Forage Mixtures and Seeding Rates
In Table 1.8-5, each forage species and mixture has been given an identification number; recommended seeding rates for pure seedings and mixtures are provided. (No-till forage seedings can be reduced 20 percent.) The numbered forages and forage mixtures have been classified by soil drainage characteristics and forage use.
