Influence of Microbial-enriched Organic Manures and Nano-emulsion Biofertilizers Combined with Inorganic Nutrients on the Growth, Yield and Economics of Chickpea Cultivation

Background: Enhancing agricultural productivity is crucial for achieving greater yields and boosting farmers’ incomes. Chickpeas, prominent pulse crops in India, play a significant role in global agricultural production. Despite their resilience to adverse conditions, optimizing chickpea growth and yield remains a challenge, necessitating integrated nutrient management strategies. Methods: The two field experiments were carried out consecutively in the same field during the rabi seasons of 2023-24 at the Instructional Farm of Karunya Institute of Technology and Sciences, to study the influence of microbial enriched organic manures and nano-emulsion biofertilizers with inorganic fertilizers on chickpea growth, yield and economics. The study consists of twelve treatments of integrated nutrient management practices in randomized block design with three replications. Result: Application of 75% RDF along with nano-emulsion biofertilizer applied as seed treatment at 10 ml kg-1 seeds and two foliar sprays at 10 ml l-1 at 30 and 45 DAS proves to be a financially feasible and environmentally sustainable approach for chickpea production.
