SUMMARY
A field experiment was carried out at AICRP on Forage Crops and Utilization, Dr. Rajendra Prasad Central Agricultural University, Pusa during Kharif season, 2020 to study the response of forage cowpea genotypes to phosphorus (P) levels. The experiment was conducted in factorial randomized
block design with four forage cowpea genotypes and three P levels (30, 60 and 90 kg P2O5/ha) with three replications. The results revealed that genotype Bundel Lobia-1 recorded 11.26, 36.18 and 66.66% higher green forage yield (GFY), dry matter yield (DMY) and crud protein yield (CPY), respectively than UPC 628. Similarly, application of 90 kg P2O5/ha recorded 8.99, 17.96 and 26.04% higher GFY, DMY and CPY, respectively than application of 30 kg P2O5/ha. Among genotypes, significantly higher net return (Rs. 12269 /ha) and B:C ratio (1.52) was registered with genotype Bundel Lobia-1. Among P levels, application of 60 kg P2O5/ha registered the highest net return (Rs. 10430/ha) while application of 30 kg P2O5/ha resulted in the highest B:C ratio (1.45).
