Abstract: A field experiment was conducted during kharif seasons of 2016 and 2017 to study the effect of dose and time of application of neem coated urea (NCU) on growth parameters, yield attributes, yield and economics of rice cultivated on silty clay loam soil of Malan, Himachal Pradesh. Results of experiment showed the superiority of NCU in improving growth and yield of transplanted rice as compared to prilled urea (without neem oil coating). Also, nitrogen application in three splits was significantly better than when either 100 % or 75 % N was applied at the time of transplanting. Application of 125% of recommended nitrogen through neem coated urea in three splits (50% basal + 25% MT + 25% PI) resulted in significantly higher yield attributes (number of panicles m-2, panicle length, number of grains panicle-1 and 1000-grain weight) as well as grain yield and straw yield and crop productivity while control treatment in which no nitrogen was applied resulted in the lowest value of yield attributes and yield. The similar trend was observed in term of economics with application of 125% RDN through NCU in three splits giving significantly higher gross returns, net returns and B: C ratio.
