Abstract: A field experiment was conducted during kharif 2016-17 and 2017-18 respectively on sandy loam soils of the Agricultural College Farm, Bapatla to study the yield, nutrient content and nutrient uptake of rice as influenced by phosphorus management practices. 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 in conjunction with inorganic fertilizer showed superior performance in terms of yield, nutrient content and nutrient uptake over alone application of inorganic fertilizer through SSP. At all the growth stages, among the phosphorus levels 150 % RDP showed significantly higher yield and nutrient uptake (kg ha-1) over 50 % RDP and it was on a par with 100 % RDP during both years and pooled data.
