A two-year field investigation showed that application of 75% RDFN+25 kg GM N+25 kg PM N to preceding rice recorded the highest values of dry matter production, pods per plant, seeds per pod, seed yield, haulm yield and NPK uptake in succeeding mungbean, which were significantly superior to other treatments which supplied 100% RDFN through different sources and 125% RDFN exclusively through mineral fertilizers. Substitution of 50 kg N/ha of 125% RDFN through different organic sources in rice resulted comparable residual effect on succeeding mungbean. There was no reduction in seed yield and yield attributes of mungbean by reducing 50% of RDF of mungbean succeeding to rice which received nitrogen through integrated manner.
