The use of integrated nutrient management practices, incorporating fermented liquid organic manures, has proven effective in promoting environmental sustainability, biodiversity, and vegetable production. A field experiment conducted over two consecutive rabi seasons assessed the impact of Jeevamrut, a fermented liquid organic manure combined with inorganic nutrients, on cauliflower growth, rhizosphere microbial populations, soil nutrient status, and yield. Ten treatment combinations were evaluated in a randomized complete block design with three replications. The pooled analysis revealed that applying 90% of the recommended dose of nutrients with 5 % Jeevamrut at 1.5 L/m2 produced optimal results for growth and yield parameters, including number of leaves per plant, plant height (cm), curd compactness (g/cm), gross curd weight (kg), marketable curd weight (g), marketable yield per plot (kg) and soil organic carbon, P, microbial activity and NPK uptake. The best economics were obtained in the treatment where 90% RDN + 5% Jeevamrut at 1.0 L/m2 was applied. Hence, it can be concluded that the application of Jeevamrut combined with RDN has the capability to improve cauliflower plant growth, yield, and yield-contributing traits on a sustainable basis.
