Herbage yield and quality of Cenchrus ciliaris by inter-cropping with Macropitilium atropurpureum was studied with six different treatments of grass legume mixture during 1982.The green and dry matter yield was found significantly higher in monoculture pure form as compared to the other treatments throughout the growing period. Legume in the pure form as well as in mixture significantly increased the total soil nitrogen in soil. The increase in crude protein contents was associated with the increase of legume in the grass legume mixture. Similarly increased of crude fiber was found with higher proportion of grass.
