Effect of phosphorus management on growth and yield of rice

Abstract

A field experiment conducted during kharif, 2016-17 and 2017-18 on clay loam soils of Agricultural College Farm, Bapatla on phosphorus management in rice. The experiment was laid out in split plot design with 12 treatment combinations with four main plot treatments and three sub plot treatments were replicated thrice. The results showed that the highest plant height, drymatter accumulation, yield attributes and grain yield were observed with green manuring in situ with dhaincha along with PSB + 150% RDP to rice. However, the highest return per rupee invested (1.28) was with 50% RDP + green manuring in situ with dhaincha along with PSB and hence was found to be optimum and economical for the production of rice.
