Effect of integrated application of nano urea and other organic sources of nitrogen on growth parameters of rice in an inceptisol of Varanasi

Abstract

With the global population rising at an uncontrollable pace, achieving sustainable agriculture and ensuring food security are of great importance. Nitrogen is an important nutrient for plant growth, and its efficient utilization is essential for maximizing agricultural productivity. However, conventional nitrogen fertilizers often exhibit low absorption efficiency and contribute to environmental pollution. This research explores the effect of the integrated application of nano urea and other organic nitrogen sources on the growth parameters of rice crop in an Inceptisol of Varanasi. The study investigates the potential of nano urea liquid, farmyard manure (FYM), vermicompost, and poultry manure as alternative nitrogen sources for rice cultivation. Nano urea, with its ultra-small particle size and high absorption efficiency, shows promise as an effective supplement to conventional urea. Additionally, organic sources like FYM, vermicompost, and poultry manure offer benefits such as improved soil health and reduced environmental pollution. The research methodology involves field experiments conducted in Varanasi's Inceptisol to assess the growth parameters of rice plants under different nitrogen treatments. Parameters such as plant height, chlorophyll content and tiller count are measured to evaluate the efficacy of the integrated application of nano urea and organic nitrogen sources. The findings of this study contribute to the understanding of sustainable nitrogen management practices in rice cultivation, particularly in regions with Inceptisols like Varanasi. By exploring the synergistic effects of nano urea and organic nitrogen sources, this research aims to enhance agricultural productivity while minimizing environmental impact.
