SUMMARY

An experiment was carried out during rabi season, 2019-20 at Forage Research Farm, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar (Haryana) for evaluating the effect of promising genotypes of berseem yield and quality at different phosphorus levels in semi-arid and sub-tropical climate. The experiment consisted of 15 treatment combinations viz., five promising genotypes (Three genotypes i.e. JHB-17-1, JHB-17-2 & PC-91, one national check i.e. Wardan and one zonal check for North West zone i.e. Bundel Berseem-2) of berseem were kept in main plots and three phosphorus levels (60, 80 and 100 kg/ha) in sub plots which were replicated thrice in a split plot design. The results of experiment showed that entry JHB-17-1 performed best in respect of green fodder yield (582.6 q/ha), dry matter yield (80.5 q/ha), crude protein yield (16.72 q/ha) and B: C (1.79). Whereas, Bundel Berseem-2 was performed best in case of crude protein
content (20.78%). Application of 100 kg P2O5/ha was proved superior in case of green fodder yield (560.4 q/ha), dry matter yield (77.8 q/ha), crude protein content (20.75%), crude protein yield (16.14 q/ha) and B: C (1.70) which was statistically on a par with application 80 kg P2O5/ha.
