SUMMARY
A field experiment was conducted at Forage Research Farm, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar (India) during winter season (Rabi) of 2022-23 to study the response of different phosphorus levels on the fodder yield, quality and economics of berseem (Trifolium alexandrinum L.) genotypes. The experiment was laid out in split plot design with six promising berseem genotypes (JB-08-17, JHB-20-1, JHB-20-2, PC-114, BB-2 and Wardan) in main plot and three phosphorus levels in sub plot (60, 80 and 100 kg P2O5/ha) and replicated thrice. Among genotypes, highest total green fodder and dry matter yield (799.3 and 114.3 q/ha, respectively) were recorded with the genotype JHB-20-2, which were at par with JHB-20-1 and BB-2. Maximum gross returns (Rs. 1,59,865/ha), net returns (Rs. 86,072/ha) and B:C (2.16) were fetched with JHB-20-2. Maximum mean crude protein content (21.34%) was estimated in BB-2 which was at par with JHB-20-1 and JHB-20-2. Among different P levels, highest green fodder and dry matter yield (776.6 and 109.3 q/ha, respectively) were recorded with the application of 100 kg P2O5/ha which were significantly superior over 80 and 60 kg P2O5/ha. Highest mean crude protein content (21.96%) was estimated with the application of 100 kg P2O5/ha which was significantly superior over the lower levels of phosphorus. Similar trend was also observed in crude protein yield. Maximum BC ratio (2.08) fetched with the application of 100 kg P2O5/ha but it was on a par with 80 kg P2O5/ha (2.03).
