Effect of Organic and Inorganic Sources of Nitrogen on Growth Parameter and Yield Attribute of Wheat in Inceptisolof Eastern Uttar Pradesh, India

Abstract

The insufficient availability and escalating expenses of fertilizers present significant constraints to crop production, exacerbating the growing disparity between nutrient demand and supply. The overreliance on agrochemicals like synthetic fertilizers, pesticides, herbicides, and fungicides not only endangers human health but also degrades soil quality and environmental integrity. This study examined the impact of applying recommended doses of fertilisers (RDF) in conjunction with organic amendments in a pot experiment carried out throughout the 2020–2021 wheat growing season. Significant improvements were found for the following wheat plant attributes: straw and grain yields; height; greenness index; spike count; spike length; and weight of 1000 seeds. The treatment utilizing 50% RDF and 50% poultry manure (T5) demonstrated the most pronounced improvements across these parameters. These findings highlight integrated nutrient management's crucial importance as a modern agricultural requirement.
