Abstract
An experiment was conducted during the kharif seasons from 1989–90 to 1996–97 to study the response of forage sorghum variety GJ-37 to different levels of nitrogen and phosphorus fertilizers on medium black soil at Dhari. Application of nitrogen at 80 kg/ha was found to be the optimum dose for increasing green and dry fodder yields, net returns, and net incremental benefit–cost ratio (ICBR). In the case of phosphorus, application of 80 kg P₂O₅/ha produced significantly higher dry fodder yield; however, 40 kg P₂O₅/ha was found to be the optimum dose in terms of net ICBR.
