Abstract: Rice (Oryza sativa L.) is the most important cereal crop of world. India ranks first in area and second in production. Global food requirements have also risen and the expected per capita food requirement is likely to double by 2050. Controlled release fertilizers may be one such solution as they are believed to enhance crop yield while reducing the environmental pollution. Viewing above facts an investigation entitled. Effect of Polymer coated urea, Neem coated urea and PGPR on growth and yield of Rice (Oryza sativa L.) in Inceptisol of Varanasi was conducted at the Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (U.P.) during the kharif season of 2017. Treatments involving split application of polymer coated urea and neem coated urea with nitrogen doses 100%, 80%, (50% + 50%) and (40% + 40%) showed a significant increase in grain and straw yield of rice as well as growth attributes such as plant height, tillers, chlorophyll content etc. Treatment T₁₂ (50% of RDN through PCU + 50% by NCU 3 Split) was applied showed a significant increase in biological yield from 112.67 to 200 gm pot^-1 with chlorophyll content from 31.46 to 51.92 and plant height from 105.09 cm in control to highest 129.94 cm in T₁₂ treatment.
