A field experiment was conducted during two consecutive years of 2008 and 2009 at Instructional Farm of NDUA&T , Kumarganj , Faizabad( U.P.) to study the effect of phosphorus, sulphur and PSB on growth attributes, yield and nutrient uptake by mungbean. The experiment consisted of four levels of phosphorus (0, 20, 40 and 60 kg P2O5ha-1), three levels of sulphur (0, 20 and 40 kg S ha-1) and two levels of seeds inoculation with PSB ( un-inoculation and inoculation ). Results revealed that the increasing levels of phosphorus up to 60 kg P2O5 ha-1, sulphur up to 40 kg S ha-1 and inoculation of seed with PSB increased the plant height, number of pods plant-1, number of seeds pod-1, seed and stover yield and uptake of N, P and S. The net return also increased with increasing levels of phosphorus and inoculation of seeds with PSB. Application of 20 kg S/ha fetched highest net return of mungbean.
