Abstract:

A field experiment was conducted during Kharif 2016-17 and 2017-18 respectively on sandy loam soils of Agricultural College Farm Bapatla to study the yield, economics and quality parameters as influenced by phosphorus management in rice-groundnut sequence.The experiment was laid out in split plot design in Kharif  rice and the treatments were replicated thrice. The treatments consisted of four main plots sources of phosphorus S1 : Inorganic fertilizer phosphorus through SSP, S2 : Green manuring in-situ with dhaincha @ 25 kg seed ha-1, S3 : Biofertilizer  (PSB) @ 750 ml ha-1, S4 : Green manuring     in-situ with dhaincha @ 25 kg seed ha-1 + Biofertilizer (PSB) @ 750 ml ha-1 and three subplots levels of phosphorus  L1 : 50% Recommended dose of P,  L2 : 100 % Recommended dose of P and L3 : 150% Recommended dose of P. Results of the experiment showed that application of in-situ green manuring + PSB along with inorganic phosphorus through SSP showed superior performance in terms of yield, quality parameters and economics over alone application of inorganic fertilizer phosphorus through SSP. Among the levels of phosphorus 150 % RDP showed higher yield, quality parameters and economics over 50 % RDP and however it was on par with 100 % RDP.
