Effect of Organic and Inorganic Sources on Growth and Yield of Soybean (Glycine max L. Merrill)

A Kharif 2024 field trial at Rajasthan College of Agriculture, Udaipur, compared four RDF levels (0–100%) with organic treatments: vermicompost (2–6 t/ha) combined with decreasing jeevamrut foliar sprays. While 100% RDF yielded strong growth, nutrient uptake, and yields (seed: 1,140 kg/ha; haulm: 2,095 kg/ha; biological: 3,236 kg/ha), the top organic treatment—6 t/ha vermicompost + 4% jeevamrut—matched or slightly exceeded these results (seed: 1,141 kg/ha; haulm: 2,085 kg/ha; biological: 3,226 kg/ha). Importantly, it also significantly improved soil health indicators—organic carbon, available N, P, K, microbial populations, and enzyme activities—making it a sustainable and effective alternative to full inorganic fertilization.
