Abstract:
Besides quantity and source, the method of nitrogen application is critical for maximizing the returns from applied fertilizer. Foliar application of nutrients improves nutrient use efficiency and reduces pollution in the environment. To evaluate the performance of foliar application of nano urea on rice growth and yield during Kharif 2021 experiment was laid out in Randomized Block Design with three replications. It consist total ten treatments viz. T1-Control, T2-100% RDF, T3- 80% RDF with one foliar application of nano urea @ 3 ml/liter every 7 days, T4- 70% RDF with one foliar application of nano urea @ 3 ml/liter every 7 days, T5- 60% RDF with one foliar application of nano urea @ 3 ml/liter every 7 days, T6- 50% RDF with one foliar application of nano urea @ 3 ml/liter every 7 days, T7-80% RDF with one foliar application of nano urea @ 3 ml/liter every 14 days, T8- 70% RDF with one foliar application of nano urea @ 3 ml/liter every 14 days, T9- 60% RDF with one foliar application of nano urea @ 3 ml/liter every 14 days and T10- 50% RDF with one foliar application of nano urea @ 3 ml/liter every 14 days. Data indicated that application of treatment T3 (80% RDF + nano-urea @ 3 ml L-1 at every 7 days) significantly increases growth parameters such as plant height and number of tillers hill-1. The foliar application of nano urea helps in easy absorption of nutrients which increases the maximum vegetative growth due to optimized nutrition of the plant. The treatment T7 significantly increases the yield and yield parameters such as number of panicles hill-1, panicles m2, number of grains panicle-1, grain yield and straw yield of paddy crop.
