Influence of Different Levels Phosphorous and Zinc on Yield and Yield Attributes of Mung Bean [Vigna Radiata L.].

To study the influence of different levels of phosphorous and zinc on yield and yield attributes of mung bean (BARI Mug 6) an experiment was conducted at Agronomy Research Farm, Peshawar, during kharif season of 2017. Four phosphorus (P) levels (0, 15, 20 and 25 kg P ha -1 ) and three zinc (Zn) levels (0, 1.5 and 4kg Zn ha -1 ) were used in the study. The results of the study shown that stover and seed yield of mung bean improved with increasing phosphorus and zinc levels up to positive level. For instance, of Phosphorous the significant maximum stover yield (2.59 t ha -1 ) and seed yield (1.53 t ha -1 ) were obtained with the treatment P3 (25kg P ha -1 ) and the significant minimum stover yield (2.08 t ha -1 ) and minimum seed yield (1.43 t ha -1 ) were obtained with the treatment P0 (0kg P ha -1 ). In case of Zn the significant maximum stover yield (2.77 t ha -1 ) and maximum seed yield (1.77 t ha -1 ) were obtained with the treatment Zn2 (4 kg Zn ha -1 ) and the significant minimum stover yield (2.19 t ha -1 ) and minimum seed yield (1.38 t ha -1 ) were achieved with the treatment Zn0 (0 kg Zn ha -1 ). The significant maximum number of branch plant -1 (3.32), taller plant (53.45cm), seed yield (1.94 t ha -1 ), yield supporting factors as number of pods plant -1 (20.89), 1000 seeds weight (45.66 g) and number of seeds pod -1 (12.98) were achieved with the treatment combination P2Zn2 (20 kg P ha -1 + 4 kg Zn ha -1 ).
