Response of different mungbean (Vigna Radiata L.) varieties to phosphorus and PSB during summer season and its residual effect on sorghum in western Uttar Pradesh

A field experiment was conducted during sammer and Kharif season of 2010 and 2011 at research farm of A. S, (PG) College, Lakhaoti, Bulandsahar, U.P. to Studies on phosphorus management in different varieties of summer mungbean and its effect on succeeding fodder sorghum. The Experiment was laid out in a factorial Randomized Block Design keeping three-treatments of bold seeded green gram varieties (Pant-moong-5, Pusa Vishal, Pusa 9531) of in main plots and six treatments of phosphorus. and bio-fertilizers in sub-plots. Results revealed that the different varieties of mungbean to phosphorus up to 50 kg P2O5 ha⁻¹ and inoculation of seed with PSB (25 kg/ha) increased the number of pods plant⁻¹, number of seeds pod⁻¹, grain and straw yield (q/ha) and uptake of NPK by succeeding fodder sorghum. The net return also increased with increasing levels of phosphorus and inoculation of seeds with PSB(25 kg/ha).
