Abstract

Low native soil P availability coupled with poor recovery of added P has become one of the major constraints limiting the productivity of crops. A field study was, therefore, conducted to compare the relative significance of fertigation and different modes of broadcast method for utilization of P when applied at the rate of 100 kg ha-1 in wheat crop. Compared to broadcast method, P applied through fertigation in single split was effectively utilized in terms of producing significantly higher crop harvests, P uptake, P recovery and agronomic efficiency. Owing to superiority of fertigation over broadcast method, it is being introduced to farming community for economizing fertilizer P and obtaining better crop harvests.
