Dry matter yield and crude protein content of four improved and one native grass species were studied at three growth stages i.e., vegetative, flowering and maturity. The highest dry matter yield in all grasses was obtained at flowering stage whereas the lowest yield occurred at maturity. Forage production of improved species was higher at each growth stage as compared to native species. Grass quality particularly the crude protein content of grasses gradually decreased with maturity. In all the species the highest crude protein level (ranging from 7.0% to 9.6%) was found at the vegetative stage. The maximum decrease in crude protein content was found between the flowering and mature stage.
