The soil of the experimental field was silty clay loam in texture; acidic in reaction; medium in organic carbon; low in available nitrogen; medium in phosphorus and potassium. The experiment was laid out in factorial randomized block design with three replications, consisting of thirteen treatments i.e. all possible combinations of ryegrass genotypes (Punjab ryegrass-1, Kashmir collection and Makhan grass) and four seed rate ratio of ryegrass:berseem (100:0, 75:25, 50:50 and 25:75) plus sole berseem sown by broadcast. Compounding of berseem with ryegrass genotypes did not exhibit any significant improvement in herbage yield over respective sole stand of ryegrass genotype. Sole Makhan grass had better plant height (cm), dry matter content (%) with higher green fodder (67.20 t ha-1), dry fodder yield (14.43 t ha-1) and crude protein yield. Sole culture of Makhan grass also realised higher net returns of Rs. 89,011 ha-1 with benefit cost ratio of 1.96.ennullThesis
