The objective of this research was to evaluate the impact of phosphorus levels (P) and tillage depths (T) on yield components and yield of mungbean (Vigna radiata L., Wilczek) under irrigated (no moisture stress) and dryland (with moisture stress) conditions. Two field experiments were conducted: one under irrigated and second under dryland conditions at the Agronomy Research Farm of The University of Agriculture, Peshawar-Pakistan during summer 2012. The impact of tillage depths and phosphorus levels was investigated on yield components and grain yield of mungbean. Three tillage depths (45, 30 and 15 cm) were used as main plots factor, while four P levels (0, 30, 60 and 90 kg P ha-1) as subplots factor under both irrigated and dryland conditions. The results revealed that higher P levels resulted in earlier physiological maturity, increased number of nodules plant-1, pods plant-1, thousand grains weight and harvest index under both irrigated and dryland conditions. The higher P levels improved yield and yield components of mungbean irrespective of tillage depths. Under irrigated condition the shallow tillage depth (15 cm) was found more beneficial in terms of yield and yield components, while the deep tillage depth (45 cm) performed better under dryland condition. We concluded from this study that application of 90 kg P ha-1 and shallow tillage (15 cm) was more beneficial for improving growth, yield and yield components of mungbean under irrigated condition. Under dryland condition, application of 90 kg P ha-1 and deep tillage (45 cm) was found better for improving growth, yield and yield components of mungbean.
