Phosphorus (P) deficiency is one of the major growth limiting factors throughout the world. Maintaining a proper P supplying level at the root zone plays a vital role in improving plant growth and yield. A field experiment was conducted to study the growth and yield responses of mungbean to varying levels of P application under different tillage systems. The treatments comprised of three phosphorus levels (30, 60 and 90 kg P per ha) and three tillage practices (zero tillage, minimum tillage and conventional tillage), were arranged in randomized complete block design (RCBD) with split plot arrangement with four replications. Results revealed that growth and yield of mungbean in term of plant population, plant height, number of pods per plant, number of seeds per pod, 1000-grain weight, seed yield, biological yield, harvest index and protein content were significantly affected by various levels of applied P and tillage systems. Although all levels of applied P produced significant effects on growth and yield of mungbean but the application of P @ 90 kg per ha gave maximum grain yield. Among the different tillage practices, conventional tillage showed relatively better performance at same input levels and produced the maximum seed yield. In case of interaction, the conventional tillage + 90 kg per ha performed better and gave the maximum grain yield compared to others. It was found that increased P levels and conventional tillage together produced most prominent effects on growth and yield of mungbean.
