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 plant height at (25, 50, 75 DAS and at harvest), CGR, RGR, Grain yield 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 plant height at (50, 75 DAS and at harvest), CGR, RGR, Grain yield 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.

Conclusion

The plant height of wheat was significantly increased with soil application of 125% RDN as compared to other treatments. Maximum crop growth rate was observed with soil application of 100% RDN and maximum relative growth rate at 50-75 DAS was found with soil application of 50% RDN, whereas relative growth rate at 75 DAS-at harvest remained statistically unchanged due to soil application of nitrogen fertilizer.It is concluded that wheat crop should be fertilized with 90 kg nitrogen per hectare and 2.5 ml L-1 nano urea or 4% urea as foliar application at 25-30 and 45-50 days after sowing to get higher growth and yield in prevailing agro-climatic conditions of Zone IVa (Sub-humid Southern Plain and Aravali Hills) of Rajasthan.
