Abstract: In India, rice is grown during kharif season and losses of applied N through leaching may be decreased through proper rate and timing of N application. However, appropriate source of N fertilizer, rate and time of application may improve N fertilizer use efficiency of the crop. Furthermore, effective rate of application for slow N releasing fertilizer like polymer coated urea (PCU) for increasing rice productivity at Varanasi districts has not been established. Therefore, A field experiment was conducted with 12 treatments and 3 replications of control, 100% of RDN through normal urea as a single basal dose and as in 3 split, and 100%, 85%, 70% and 55% RDN through PCU as single basal doses and as in 3 split under randomized block design (RBD) on rice variety HUR-105 during kharif season 2016. The last treatment (T12) was comprising with 55% of RDN through PCU as basal dressing + 2 tons FYM ha-1 + PGPR (mixture of Azotobactorchroococcum, Pseudomonas aeruginosa, Pseudomonas flurescens, Pseudomonas putida, Bacillus subtilis, Azospirillumbrasilense, Trichodermaharzianum).
