Efficacy of Phosphorus and PSB Response in Different Varieties of Summer Moongbean and Its Residual Effect on Fodder Sorghum in Western Uttar Pradesh

Abstract

An experiment is conducted during two consecutive year 2010 and 2011 at Agriculture research Farm, Amar Singh (PG) College, Lakhaoti, Bulandshahr, Uttar Pradesh. The soil of the experimental site was sandy loam with pH (8.10) and EC (0.36 dSm-1) of soil water suspension. Low in organic carbon 3.9 g kg-1.soil and status of soil in available nitrogen, phosphorus and potassium was medium. The experiment was designed in factorial RBD (Random Block Design) keeping three treatments of bold seeded moongbean varieties (Pusa Vishal, Pant Mung-5 and Pusa 9531) in main plots and six treatment ( T1 0 kg P2O5 ha-1, T2 0 kg P2O5 ha-1 + 25 kg PSB ha-1, T3 25 kg P2O5 ha-1 T4 25kg P2O5 + 25 kg PSB ha-1,T5 50 kg P2O5 ha-1 and T6 50kg P2O5 ha-1 + 25 kg PSB ha-1) of phosphorus and bio-fertilizer in sub-plots with four replication. The total number of treatment were 18 and number of plots was 72. Results revealed that the different varieties of moongbean to phosphorus up to 50 kg P2O5 ha-1 and inoculation of seed with PSB (25kg ha-1) increased the number of pods plant-1, number of seeds pod-1 grain and straw yield (q ha-1) and uptake of NPK by succeeding fodder Sorghum. The net return also increased with increased levels of phosphorus and inoculation of seed with PSB (25kg ha-1).
