Soybean herbage yield, nutritional value and profitability under integrated manures management

Organic manures are more preferred and environmentally friendly than chemical fertilizers for minimally contaminating soil, water environmental resources, but the determination of right source organic continues to remain an unexplored aspect. Considering important issue, a multi-year field trial was carried out determine response forage soybean four sources nutrients such as (IF), poultry litter (PL), bovine’s farm yard slurry (BFYS) sewage sludge (SS) their seven binary combinations (PL+BFYS, PL+SS, PL+IF, BFYS+SS, BFYS+IF, SS+IF PL+BFYS+SS). Supplementation with mineral remained superior sole application, particularly BFYS + IF found significantly (p?0.05) yielding highest fresh biomass (23.9, 26.4 25.7 t ha–1) improved nutritional quality. The same combination integrated fertilizer management also recorded higher sustainability per sustainable yield index along net income benefit-cost ratio. PL SS applied in conjunction performed better or application manures. Therefore, may be recommended adoption produce comparable quality reducing dependency on fertilizers.
