Higher uses of fertilizers reduce the quality of food produced as well as soil fertility. However, combination of inorganic and organic will reduce the environmental hazard due to higher fertilizer use efficiency as well as improvement of the quality of crops. Current status of lack of availability of organic substances makes us to think the other cheap organic resources. The organic matter stimulates plant growth, improves plant resistance under unfavourable condition. A study was conducted to assess the influence of few organic fertilizers to observe their influence on yield and quality of soya bean and the impact of the manures on post harvest soil. The yield obtained on 90 DAS was found to be the maximum in plants applied with panchagavya, humic acid and micro herbal fertilizer (T₃). The maximum pods (10.5), number of seeds (25 seeds plant^-1), ascorbic acid (0.72 mg g^-1) and protein (1.37 mg g^-1) content of the harvested seeds were significantly increased due to the combined inoculation of panchagavya, humic acid and micro herbal fertilizer. The physical characters and macro nutrient contents of the post harvested soil (N (88), P (8.6) and K (325) kg ha^-1) were higher in panchagavya, humic acid and micro herbal fertilizer treated soil compared to other treatments.
