Introduced Pasture Grasses and Legumes
Evaluation of new grasses and legumes involves initial evaluation
in small plots where they are evaluated for persistence, yield, and nutritive value.
Promising entries are subsequently evaluated in grazing trials to evaluate livestock
performance. Research is conducted on new and existing forages to improve methods of
establishment, yield, nutritive value, and persistence. Demonstration trials on ranches
are sometimes conducted to validate research results.
