Efficiency of Hydrolyzed Tannery Solid Waste for the Growth and Yield Potentials on Tomato

Animal fleshing (ANFL) is generated as a solid waste from the tannery industries. The present study involved the use of hydrolyzed animal fleshing (HANFL) as a source of fertilizer for tomato plants (Lycopersicon esculentum L.). The treatment involved four different strengths of HANFL: 25% (T1), 50% (T2), 75% (T3), 100% (T4), and recommended dose of NPK fertilizers (T5) with tap water serving as the control (C). Chlorophyll, carotenoid, and protein contents of leaves were estimated on 30, 60, and 90 d after transplantation. The application of HANFL has enhanced plant growth, yield and altered the overall biochemistry in proportion to the HANFL concentrations. The fruit quality of T4 treated plants was better in terms of protein, carbohydrate, and vitamins content than those of the other treatments. Hence, it was inferred that 100% HANFL boosted both growth and yield better than the other concentrations besides NPK fertilizer.
