SUMMARY
A field experiment was conducted at Agricultural Research Station, SKRAU, Bikaner on sandy loam soil during rabi season of 2016-17 to study the effect of P levels on forage yield of promising multicut genotype of berseem. The experiment consisted of five treatment combination of berseem genotype ( AVTB2-1, AVTB 2-2, AVTB 2-3, AVTB 2-4, AVTB 2-5) in main plot and 3 phosphorus levels (60,80 &100 kg/ha) in sub plot. The experiment was laid out in randomized complete block design and replicated thrice. The result show that Berseem genotype namely AVTB 2-3 performed better and recorded higher plant height, GFY, DMY and CPY along with net return and B:C ratio in compared to rest all genotypes. While application of phosphorus @80 kg/ha gave the maximum GFY (143.7q/ha) and L:S ratio (1.27) being at par to 60 kg/ha and gradually decreased at higher dose of phosphorus application. Though, growth, quality and economic values were recorded higher at 60 kg/ha phosphorus application. further, plant stand /m2 recorded at 30 DAS was showed non significant variation due to different phosphorus levels and genotype.
