dc.description.abstractA field experiment was conducted to study the effect of nitrogen levels and modified urea on growth, yield and nitrogen use efficiency in rainfed pearl millet during kharif 2016 at Regional Agricultural Research Station, College of Agriculture, Vijayapura, UAS, Dharwad. There were 15 treatment combinations involving three nitrogen levels viz., 25, 50 and 75 kg ha-1 and five modified ureas viz., neem coated, tar coated, sulphur coated, vermicompost coated and normal urea. The experiment was laid out in factorial randomised block design with three replications. The results indicated that, application of 75 and 50 kg N ha-1 were at par and recorded significantly higher grain (2,878 and 2,730 kg ha-1, respectively) and stover yields (5.32 and 5.15 t ha-1, respectively) compared to 25 kg N ha-1(2,296 kg ha-1 and 4.00 t ha-1, respectively). Application of neem coated urea recorded significantly higher grain (2,965 kg ha-1) and stover yields (6.13 t ha-1) to normal urea. Net income and benefit cost ratio were higher with application of 75 kg N ha-1 (Rs. 28,815 ha-1 and 2.91, respectively) compared to 25 kg N ha-1 (Rs. 21,366 ha-1 and 2.57, respectively), however it was at par with 50 kg N ha-1 (Rs. 27,517 ha-1 and 2.90, respectively). Among the modified ureas, neem coated urea recorded significantly higher net income (Rs. 32,316 ha-1) and benefit cost ratio (3.32) compared to normal urea (Rs. 23,817 ha-1 and 2.69, respectively) and other modified ureas. Application of 50 kg N ha-1 with neem coated urea was found to be optimum in pearl millet crop to achieve higher grain yield, stover yield and economic returns.
