Abstract
Mungbean is one of the important grain legume crops in Pakistan due to its vigorous growth even in adverse environment. Mungbean is part of daily cuisine in the country but its production is low mostly due to imbalance fertilization. The study was carried out to find best combination of nitrogen (N), phosphorus (P) and potassium (K) for maximum production under less fertile soils during 2017-2018. In this study, three combinations of NPK (i.e., 30:30:0, 30:60:0 and 30:60:30 kg ha-1 ) were compared with control (without fertilization). Maximum pods per plant (22.43), pod length (9.51 cm), seeds per pod (8.97), 1000 seed weight (44.07 g), seed yield (1163 kg ha-1 ), biological yield (5231 kg ha-1 ) and harvest index (24.63 %) were obtained from 30:60:30 kg NPK ha-1 during 2017 and similar trends were found during 2018. Maximum leaf area duration (212.64, 215.09 days), crop growth rate (3.99, 4.02 g m-2 d -1 ), net assimilation rate (2.46, 2.54 g m-2 d -1 ) and fraction of intercepted radiation (0.89, 0.88 MJ m-2 ) were obtained from mungbean plant under 30:60:30 kg ha-1 NPK application during 2017 and 2018, respectively. These results are suggesting that integrated application of nitrogen, phosphorous and potash is very imperative to attain higher production of mungbean under semi-arid environments. It is concluded from the findings that farmers can harvest maximum final outputs of mungbean by the application of 30:60:30 kg ha-1 NPK, respectively
