Abstract
The field experiment was carried out at the Students Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) during the two consecutive kharif seasons of 2023 and 2024 to evaluate the “Effect of nano urea on growth, productivity, and economic return in transplanted rice (Oryza sativa L.). The experiment was laid-out in a Randomized Block Design with 3 replications and 9 treatments. i.e. T1: 125% RDN through Urea (50% as basal + 25% at active tillering stage and Panicle initiation), T2: T1+ Two spray of Nano Urea at active tillering stage and Panicle initiation, T3: 100% RDN through Urea in three splits (50% as basal + 25% at active tillering stage and Panicle initiation stage), T4: T3 + Two spray of Nano Urea at active tillering stage and panicle initiation stage (@ 4 ml/ litre of water, T5: 75% RDN through Urea (50% as basal + 25% active tillering stage and panicle initiation stage), T6: T5 + Two spray on Nano Urea at active tillering stage and panicle initiation stage, T7: 50% RDN through Urea (50% basal + 25% at active tillering stage and panicle initiation stage), T8: T7+ Two spray of Nano Urea at active tillering stage and panicle initiation stage, T9: Control. Rice variety Sarju-52 was sown. Recorded growth parameters showed that maximum Plant height (108.66 cm), Number of tillers hill-1 (10.83), Fresh weight (g.) plant-1 (146.44 g.), Dry weight (g.) plant-1 (42.67), Leaf area index (6.07), were achieved under treatment T2: T1+ Two spray of Nano Urea at active tillering stage and Panicle initiation.
