Response of Mungbean Yield and Yield Components into Various Levels of Phosphorous

This study was aimed to help the farmers to decide the optimum dose of phosphorous fertilizer whether they can use the recommended dose for achieving higher yield of mungbean in agro climatic condition of Peshawar. Farmers need to know what fertilizer application rate they should use under their conditions for adequate productivity. To obtain these objectives an experiment was carried out at Agricultural Research Farm Agricultural University Peshawar during 2017. Five levels of P i.e. 0, 20, 40, 60 and 80 kg ha-1 on mung bean were studied in the experiment. Mungbean cultivar NM-92 was sown in the experiment. Phosphorus application was significant for all the parameters. Plots treated with 60 kg P ha-1 produced maximum nodules plant-1 (25), pods plant-1 (22), seeds pod-1 (11), 1000 grains weight (40.2 g), biological yield (4595 kg ha-1), grain yield (1139 kg ha-1) and harvest index (28.6 %) as compared with control plots but seeds pod-1, 1000 grains weight, grain yield and harvest index was statistically at par when plots treated with 80 kg P ha-1. Increased in fertilizer has increased these parameters up to some extent and a decreasing trend was observed beyond 40 kg ha-1 phosphorous application. Regarding yield 80% variations was accorded by the phosphorous application. Based on the above facts it is concluded that mungbean cultivar NM-92 applied with 60 kg P ha-1 was better in terms of yield and yield components and may be recommended for cultivation in agro-climatic condition of Peshawar.
