Pulses are one of the distinct health-benefit food crops globally, due to their low-fat content and higher protein content. Pulses are an essential group of crops in India, which are also responsible for yielding significant financial gains accounting for a large part of the exports (Anon et al., 2022). India is one of the agricultural countries, and food is a vital need for our country due to the growth of population (Vaithiyanathan and Sundaramoorthy, 2016). Green gram (Vigna radiata L.) is one of the most important and extensively cultivated pulse crops. India shares approximately 35-37% and 27% of the total area and production of pulses, respectively, in the world. Green gram, commonly known as “mung” or “mung bean”, is the most important crop of South East Asia and particularly the Indian subcontinent (Ranpariya et al., 2017). India is the largest producer and consumer of pulses in the world, accounting for about 29% of the global area and 19% of the world’s production. Even more importantly, India is the world’s largest importer and processor of pulses. Fatefully, the country’s pulse production has been around 14-15 mt, coming from a near-stagnant area of 22 m ha. (Singh et al., 2015). In India, the area under green gram is 654 lakh hectares, with a production of 599 lakh tonnes, with a productivity of 916 kg ha-1 (Joshi et al., 2020). Integrated Nutrient Management (INM) is a comprehensive approach to manage nutrients for crops that maximises productivity while minimises environmental impact. It combines the use of chemical fertilisers, organic manures, and other nutrient sources to ensure that plants receive the right amount of nutrients at the right time. It improves crop yields and soil health by efficiently utilising nutrients, including chemical fertilisers, organic matter (such as compost and manure), and crop residues. By reducing fertiliser costs and preventing soil degradation, integrated nutrient management is a smart way to grow healthy crops, protect the environment, and save money. It combines traditional and modern methods to provide plants with the necessary nutrients without overusing fertilisers, promoting sustainable agriculture. The present investigation aims to evaluate the impact of Integrated Nutrient Management (INM) practices on the growth, yield, and economics of green gram under the agro-climatic conditions of Trichy, Tamil Nadu. The findings are expected to provide scientific insights into nutrient use efficiency, soil fertility improvement, and sustainable production of green gram. By assessing both biological and economic responses, the study seeks to generate location-specific recommendations for farmers.
