The Impact of Nano-fertilizers on Growth-attributing Characteristics in Transplanted Hybrid Rice (Oryza sativa L.)

The experiment was conducted during the kharif season of 2022 and 2023 at Students’ Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur- 208002 (U.P.) India. The experiment was laid out in Randomized Block Design with three replications. 13 treatments viz, T1- Control, T2-50 % RDN, T3-50% RDN+ Nano Urea, T4-75% RDN, T5-75% RDN + Nano Urea, T6-100% RDN, T7-100% RDN + Nano Urea, T8-50% RDN + Nano Zinc, T9-50% RDN + Nano Urea + Nano Zinc, T10-75% RDN + Nano Zinc, T11-75% RDN + Nano Urea + Nano Zinc, T12-100% RDN + Nano Zinc and T13-100% RDN + Nano Urea + Nano Zinc. Higher growth attributing characters such as higher plant height, tillers, dry matter accumulation and leaf area index at different crop stages along with maximum grain yield were recorded with application of 100% RDN + Nano Urea + Nano Zinc and over Control, 50 % RDN, 50% RDN+ Nano Urea, 75% RDN, 75% RDN + Nano Urea, 100% RDN, 50% RDN + Nano Zinc and 75% RDN + Nano Zinc in transplanted Kharif rice.
