Assessment of Organic, Inorganic and Integrated Nutrient Management Practices on Yield and Economics of Groundnut during the Kharif Season

Abstract

Achieving sustainable and balanced food production is a difficult task given the rising food demand brought on by the world's fastest population growth. Taking this into account, an On Farm Trial (OFT) on the effect of organic, inorganic and Integrated Nutrient Management (INM) practices on groundnut growth, yield attributes, yield and economics was conducted in 5 locations at Krishi Vigyan Kendra (KVK) operated mandals in Kalikiri during the Kharif seasons from 2021-2022 to 2023-2024 on 2.0 ha of rainfed alfisols. The study revealed that INM practice recorded higher yield attributes, pod yield, gross return, net return and return per rupee invested than organic and inorganic nutrient management practices. The improvement in pod yield in INM was 11.9% and 7.8% over organic and inorganic nutrient management practices, respectively. Similarly, INM recorded higher gross returns (63,637 Rs. /ha), net returns (22,983 Rs. /ha) and B:C ratio of 1.56 as compared to organic and inorganic nutrient management practices. Results of the study suggested the integrated use of organic and inorganic sources of nutrition for increasing groundnut productivity and economic stability of groundnut farmers of Chittoor district.
