Abstract: A field experiment was conducted at Agronomy, Research Farm of Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during the kharif season of 2011 to evaluate the effect of nitrogen and phosphorous on yield and quality of scented rice cv.Pusa Basmati-1. The experiment was conducted in randomized block design with three replication. The sixteen treatments consisting of 4 nitrogen levels (N0, N40, N80, N120) and 4 phosphorus level (P0, P20, P40 and P60). The soil of the experiment site was silty loam in texture having pH-8.2, organic carbon 0.36% available nitrogen 161.5 kg ha-1, available phosphorus 14.5 kg ha-1 and available potash 295 kg ha-1. The crop received recommended agronomic practices. All the growth and yield attributes increased significantly with increase in nitrogen level up to 80 kg N ha-1 though the highest value were recorded with 120 kg N ha-1. The highest grain yield of 27.62 q ha-1 was recorded with 120 kg N ha-1 which was at par with 80 kg N ha-1 and significantly better over control and 40 kg N ha-1 showing an increase of 0.38, 3.88 and 7.25 q ha-1 over 80, 40, 0 kg N ha-1, respectively. Application of phosphorus resulted increase in all the growth and yield attributes significantly with increase in dose of phosphorus up to 40 kg P2O5 ha-1 only. The maximum grain yield of 28.78 q ha-1 was recorded with application of 40 kg P2O5 showing an increase of 23.46 and 47.58 per cent over, 20 kg P2O5 ha-1 and control respectively. Nitrogen and Phosphorus levels failed to influence the quality parameter of scented rice such as hulling percentage, kernel length, kernel breadth, L: B ratio, KLAC, water absorptions during cooking, amylose and protein content significantly.
