SUMMARY
A field experiment was conducted at CCS Haryana Agricultural University, Hisar (Haryana) during winter season (rabi) of 2014-15 to study the response of different phosphorus levels on the yield and quality of berseem (Trifolium alexandrinum L.) genotypes. Seven berseem genotypes viz., JBSC 1, JBSC 2, JBSC 3, JBSC 4, Bundel berseem 2, Wardan and Mescavi were sown with 60, 80 and 100 kg P2O5/ha. Among genotypes, JBSC 4 recorded highest number of shoots/m2 (656.78), green fodder (425.89 q/ha) and dry matter yield (38.54 q/ha). JBSC 4 was also found superior in terms of crude protein content (18.75%) and crude protein yield (7.23 q/ha). Among different phosphorus levels, highest green fodder (380.86 q/ha) and dry matter yield (34.26 q/ha) were recorded with the application of 100 kg P2O5/ha which were on a par with 80 kg P2O5/ha but significantly superior over 60 kg P2O5/ha. Maximum crude protein content (18.38%) was estimated with the application of 80 kg P2O5/ha. However, its yield revealed increasing trend with increased levels of phosphorus, maximum with 100 kg P2O5/ha. Among genotypes, the maximum gross returns (Rs. 53,236/ha), net returns (Rs. 28,376/ha) and B : C ratio (1.14) were fetched with JBSC 4 closely followed by JBSC 2. Among different phosphorus levels, the maximum gross returns (Rs. 47,608/ha), net return (Rs. 21,786/ha) and B : C ratio (0.84) were fetched with the application of 100 kg P2O5/ha closely followed by 80 kg P2O5/ha.
