A field experiment was conducted at Instructional Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad during Kharif season 2012 to evaluate the effect of sources and split application of phosphorus on dry matter accumulation, nutrients uptake and soil properties under partially reclaimed salt affected soil. The experiment comprised of seven treatments i.e. (T1) control, (T2) 60 kgP2O5 ha-1 basal through DAP, (T3) 45 kg basal +15 kg P2O5 ha-1 at tillering through DAP, (T4) 30 kg basal+15 kg P2O5 ha-1 through DAP, (T5) 60 kg P2O5 ha-1 basal through SSP, (T6 ) 45 kg basal + 15 kg P2O5 ha-1 in Randomized Block Design replicated thrice. The rice variety NDR-359 was taken as test crop. Among sources of phosphatic fertilizer viz., single super phosphate and diammonium phosphate, single superphosphate were found more effective over diammonium phosphate with respect of dry matter accumulation, phosphorus uptake, EC, pH, OC and available nitrogen, phosphorus and potassium in soil.

The experiment comprised of seven treatments i.e. (T1) control, (T2) 60 kgP2O5 ha-1 basal through DAP, (T3) 45 kg basal +15 kg P2O5 ha-1 at tillering through DAP, (T4) 30 kg basal+15 kg P2O5 ha-1 through DAP, (T5) 60 kg P2O5 ha-1 basal through SSP, (T6 ) 45 kg basal + 15 kg P2O5 ha-1 in Randomized Block Design replicated thrice. The rice variety NDR-359 was taken as test crop. Among sources of phosphatic fertilizer viz., single super phosphate and diammonium phosphate, single superphosphate were found more effective over diammonium phosphate with respect of dry matter accumulation, phosphorus uptake, EC, pH, OC and available nitrogen, phosphorus and potassium in soil.
