Adequate regulation of mineral nutrients plays a significant role in improving plant growth and development. Keeping in view the role of plant nutrition, field experiments were conducted at Adaptive Research Farm and two different locations at farmer's fields to investigate the effects of potassium (K) on growth and yield of mungbean under arid climate. Five treatments including T1 = Control; T2 = K @ 25 kg K2SO4 per ha; T3 = K @ 50 kg K2SO4 per ha; T4 = K @ 75 kg K2SO4 per ha; T5 = K @ 100 kg K2SO4 per ha were arranged in randomized complete block design with three replications. AZRI-2006, a promising variety of mungbean for arid climate, was used as a test variety. Results showed significant impacts of applied K on plant height, number of grain per pod and grain yield as compared to control. Among different treatments, T4 (K2SO4 @ 75 kg per ha) caused more prominent increase in yield and yield contributing parameters. It was concluded that K helped to improve the growth and yield of mungbean which played an important role in maintaining soil fertility.
