Effect of different methods and rates of phosphorus application in mungbean

Abstract

Poor performance of fertilizer phosphorus is one of the major causes depressing the productivity of the crops. An investigation was, therefore, carried out under field conditions to compare the relative efficacy of broadcast, banding and fertigation technique for improving P use efficiency in mungbean. The response to P applied through fertigation was more pronounced as compared to broadcast and banding method. Significantly highest mungbean yield, P uptake, P recoveries and agronomic efficiency were recorded with fertigation and the lowest with broadcast method. The low rate of P application resulted in a relatively higher P recovery and agronomic efficiency compared to higher rate of P application by either method.
