Productivity and Profitability of Transplanted Rice (Oryza sativa L.) as Influenced by Split Application of Neem Coated Urea

Abstract

A field experiment was conducted during Kharif season 2016 at Research Farm of Birsa Agricultural University, Ranchi, Jharkhand to study productivity and profitability of transplanted rice (Oryza sativa L.) as influenced by the split application of neem coated urea. The experiment was done out in a randomised block design with three replications and nine treatments. The result showed that the split application of neem coated urea (NCU) significantly influenced the growth and yield attributes, yields and economics viz. plant height, total tillers, dry matter accumulations, CGR, productive tillers/m2, grains/panicle and 1000 grain weight. Application of 125 % NCU 1/3rd basal + 1/3rd Max. Tillering + 1/3rd PI was significantly better than all the treatments but was found at par with treatment T3 and T2. The plant height at 30, 60, 90 and at maturity (31.6, 68.3, 106.2 and 104.4 cm), number of tillers/m2 (169, 311, 305 and 301), dry matter accumulations (185.27, 616.10, 997.30 and 1311.07) respectively, CGR at 30-60 DAT, 60-90 DAT and 90 to maturity (14.36, 12.71, and 9.96 g/m2/day) and productive tillers/m2 (291), grains/panicle (123), fertile grains/panicle (118), 1000 grain weight (24.23 g), maximum grain yield (56.70 q/ha), straw yield (82.10 q/ha), harvest index (40.52), net return (64765Rs/ha) and B: C ratio (2.21) with 125% NCU applied in three splits which was at par with T1, T2 and T3.
