Abstract: A pot experiment was conducted in department of Soil Science and Agricultural Chemistry of College of Agriculture, Central Agricultural University, Imphal (Manipur) during kharif season of 2016, to study the effect of Single Super Phosphate (SSP) and Rock Phosphate (RP) on nutrient uptake of paddy (CAU-R1). Results revealed that phosphorus uptake increase up to 75 days with slight decline on 100 days and an increase at harvest. Comparatively higher P-uptake in T6 (25% RD of P2O5 from SSP + 75% RD of P2O5 from RP, RD- Recommended Dose) which is at par with T5 (50% RD of P2O5 from SSP + 50% RD of P2O5 from RP) and T3 (100% RD of P2O5 from RP). T4 (75% RD of from SSP + 25% RD of P2O5 from RP) shows comparatively higher accumulation of P-concentration in plant at different stages starting from 50th day up to harvest which is at par with T6. Critical study of the data revealed more dry matter accumulation in paddy grown in T6 added soil on 100th day and T5 at harvest which are at par with T5 and T6, respectively.
