Abstract:
To improve nutrient use efficiencies, production and productivity nano urea is a critical component. As the major way to supplement nitrogen is with urea. It becomes more difficult to top dress, which also reduces efficiency. Thus, the recent experiment was conducted at the Research Farm, Department of Agronomy, Rajasthan College of Agriculture, Udaipur (Rajasthan) during 2021-22 and 2022-23 at different levels of recommended dose of nitrogen (RDN) for soil application and levels of Nano Urea and Urea for foliar spray were studied. The experiment was laid out in split plot design with three replications and comprised twenty five treatment combinations (five-soil application and five-foliar application). Soil application of 125% RDN was significantly increased Grain yield, straw yield, biological yield, hectoliter weight, grain hardness index and protein content over soil application of 75% RDN, 50% RDN and control, respectively on pooled basis. However, 125% RDN and 100% RDN were found at par with each other. foliar application of nano urea at 25-30 DAS and 45-50 DAS significantly increased Grain yield, straw yield, biological yield, hectoliter weight, grain hardness index and protein content as compared to control (Water spray), which was at par with foliar application of nano urea at 25-30 DAS, urea at 25-30 DAS and urea at 25-30 DAS and 45-50 DAS.
