Impact of Phoshporus Levels on Yield and Yield Attributes of Mungbean Cultivars under Peshawar Valley Conditions

The objective of this study was to determine the effects of phosphorus levels on yield and yield components of mungbean cultivars ( Vigna radiata L.). Therefore the field experiment was carried out at New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during summer 2013. The experiment was laid out in randomized complete block design with three replications. Six level of phosphorus in the form of SSP (0, 20, 40, 60, 80 and 100 kg ha -1 ) and three cultivars of mungbean (NM-98, NM-92 and NM-54) were used. Phosphorus application was significant for all the parameters. Plots treated with 80 kg P ha -1 produced maximum nodules plant -1 (25), pods plant -1 (22), seeds pod -1 (11), 1000 grains weight (40.2 g), 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 100 kg P ha -1 . The cultivar NM-98 had the maximum nodules plant -1 (21), pods plant -1 (20), seeds pod -1 (11), 1000 grains weight (38.4 g), grain yield (1030 kg ha -1 ) and harvest index (28.2 %) as compared with other mungbean cultivars. It was concluded from the present research work that cultivar NM-98 treated with 80 kg P ha -1 improved mungbean productivity and thus, it is recommended for general practice in agro-climatic conditions of Peshawar valley.
