Background: Indiscriminate management of chemical fertilizer is the major cause of deterioration of soil health, yield, sustainability and biodiversity. The effect of Yeast vinasse, a by-product of bakery industry,on the growth, yield and quality of soybean as well as soil fertility and biological properties was evaluated over conventional manures through integrated nutrient management. 
 
Methods: Field experiment was conducted during kharif seasons of 2020 and 2021 at Bidhan Chandra Krishi Viswavidyalaya (BCKV), West Bengal, India in sandy loam soil (Entisol) with eight nutrient treatments combining organic sources (FYM, Vermicompost and Yeast vinasse) with inorganic NPK fertilizers and ZnSO4 foliar spray in randomised block design replicated thrice. Standard procedures were followed for plant and soil analysis.&nbsp; 
 
Result: Vermicompost 1.5 t ha-1 along with 75% RDF and 0.5% ZnSO4 foliar application showed highest growth, yield, quality and nitrogen and phosphorus uptake by the crop, which was statistically at par with 2 t ha-1 yeast vinasse along with 75% RDF and 0.5% ZnSO4 foliar spray. The same treatments also exhibited higher soil organic carbon content and microbial activity; available nitrogen (N), phosphorus (P), potassium (K) and zinc (Zn) status of soil over other treatments.
