Effect of Integrated Nutrient Management on Growth, Yield and Quality of Chickpea (Cicer arietinum L.) Crop

Abstract

A field experiment was conducted to evaluate the impact of various organic and inorganic fertilizer combinations on the growth, yield, and quality of chickpea (Cicer arietinum L.). The study investigated nine different nutrient management treatments, including control, varying percentages of recommended doses of fertilizers (RDF), vermicompost, and Rhizobium inoculation, both individually and in combination. Results indicated that integrated nutrient management (INM) significantly enhanced plant population, height, branching, pod and seed formation, dry matter accumulation, 100-seed weight, and ultimately grain, straw, and biological yields. Specifically, the treatment combining 75% RDF with 5 t/ha vermicompost and 20g/kg seed Rhizobium inoculation consistently outperformed other treatments, leading to the highest yields and improved seed nutrient content (NPK). Economic analysis further revealed that INM practices significantly increased gross returns and net profits, demonstrating their economic viability and sustainability. This research underscores the critical role of balanced nutrient application through INM for maximizing chickpea productivity and ensuring long-term agricultural sustainability.
