Abstract: Enhancing crop yield and fertilizer use efficiency is being a major challenge to meet the food and nutritional security of ever increasing population and also to conserve the natural resources from degradation. In this investigation, it is aimed to study application of oleoresin and neem coated urea on enhancement of yield and nitrogen use efficiency of maize. A field experiment was conducted by growing maize (Zea mays L.) var. Nutan KH-101on a Vertisol. The treatments were neem coated urea (NCU) and pine oleoresin coated urea (RCU) at 100% and 75% recommended doses (RDs), normal urea (100% RDs)and absolute control (without any fertilizers). In all the treatments P and K (100% RDs) were applied except in control. The percent grain yield increase in RCU and NCU over normal urea at 100% RDs was 30.1% and 25.4%, respectively. Agronomic efficiency, recovery efficiency and partial factor productivity were significantly higher in coated urea applied treatments than that of normal urea applied treatment. The N recovery efficiency of RCU, NCU and urea was 49%, 52% and 33%, respectively. Further application of coated urea at 75% RDs also over performed the normal urea for improving crop yield. Moreover both neem and pine oleoresin coated urea applied treatments were almost equal in their impact on maize yield and nutrient uptake, that indicates resin coated urea could be a good alternative N source to neem coated urea that is largely consumed in India at present.
