An experiment was conducted at Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore, Tamil Nadu (India) for assessing the effect of biocomposted corncob and coirpith on biochemical constituents in leaves and seeds of soybean. The treatment T6 - compost 6 (Raw coirpith predigested by using Pleurotus sajor-caju and Eudrilus eugeniae (5t/ha) showed increased protein and carbohydrate content followed by other treatments. A significant increase in protein and carbohydrate content was noted in T6 treatment (97.45 mg/g tissue and 76.56 mg/g tissue) on 50 DAS in leaves. Maximum protein and carbohydrate content was achieved in seeds (64.08 and 97.55 mg/g tissue) on 90 DAS. Among the treatments, T6 showed promising results for protein and carbohydrate content in leaves and seeds as compared to the other treatments and control. Hence, organic manure like biocomposted corncob and coirpith can be recommended as effective organic fertilizer for enhancement of protein and carbohydrate in Glycine max L. (Merill) Var. Co. 7 Soy 3.
