The present field study was carried out at two locations viz. Punjab Agricultural University, Ludhiana and CCS Haryana Agricultural University, Hisar during rainy season (kharif) 2017 to evaluate seven entries/varieties of forage sorghum with three levels of fertility (75, 100 and 125 percent of RDF). The experiment was laid out in factorial randomised block design and replicated thrice at both the locations. The results revealed that CSV 21F out yielded the remaining varieties for green fodder yield and dry matter yield on location mean basis. It was also superior over other varieties with respect to growth characteristics such as plant height, tillers and leaf: stem ratio. The green fodder yield, dry matter yield and growth characteristics of sorghum increased significantly with the increasing fertility level up to 125 percent RDF (Recommended Dose of Fertilizer) at both the locations and on pooled basis. Highest gross returns, net returns and benefit cost ratio on pooled basis of both the locations was recorded in the genotype CSV 21F followed by SPH 1822, SPV 2387 and SPV 2388.
