Abstract: A field experiment was conducted during kharif season of 2017 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). The soil of the experimental field was well drained, loam in texture, alkaline in reaction (pH 8.12), low in available nitrogen, medium in available phosphorus and available potassium with an electrical conductivity of 0.23 dSm-1. Nine treatments comprising control (No N), 120 (RDN) N through urea at basal, maximum tillering and panicle initiation, respectively or 50:25:25 N, 50:50:00 N through urea at basal, maximum tillering and panicle initiation, respectively, 25:25:50 N through urea at basal, maximum tillering and panicle initiation, respectively, 75:12.5:12.5 N through urea at basal, maximum tillering and panicle initiation, respectively, 50% N, through urea at basal, and rest through LCC, 33% N through urea at basal, rest through LCC, 50% N through urea at basal, rest through SPAD, and 33% N through urea at basal, rest through SPAD, replicated thrice estimated in a randomized block design. The experimental results revealed that the soil with highest available nitrogen, phosphorus, potassium and Organic carbon was recorded in T6 (application of 50% N through urea as basal, rest through LCC) at tillering, panicle initiation (PI) and harvesting stages respectively.
