Abstract:
The experiment was carried out to determine the optimum potassium levels and its effects on growth, yield and quality of mungbean (NM-92, NM-54 and NM-51). The yield relationship in NM-51 with its yield components was found to be positively correlated and significant, whereas NM-92 and NM-54 was non-significant. Number of pods per plant, number of seeds per pod were significantly affected by potash applications but 1000 seed weight remained unaffected. Among the fertilizer levels 50 kg K2O per hectare produced the highest average seed yield of 832 kg per hectare however the optimum level was between 50 to 100 kg K2O per hectare.
