Agro-industrial wastes such as sugarcane bagasse, molasses and press mud are giving rise to huge amounts of agricultural residues. These wastes have the potential to supply feedstock for biochar production. The Nutrient Enriched Biochar (NEB) was prepared by utilizing these wastes with the nutrient composition (NPK) of 7 : 7 : 7. A field experiment was conducted during 2016-17 by following randomized block design to study the effect of nutrient enriched biochar from sugar industry wastes on yield of hybrid maize (NK6240) on Typic Rhodustalf (Alfisol) of Tamil Nadu. The treatments were Absolute Control (T1), 50% RDF through NEB (T2), 75% RDF through NEB (T3), 100% RDF through NEB (T4), 125% RDF through NEB (T5), 50% RDF through NEB and 50% RDF through inorganic fertilizers (T6) and 100% RDF through inorganic fertilizers (T7). The results of the field experiment revealed that the grain yield (5677 kg ha-1) and stover yield (9504 kg ha-1) significantly increased up to 125% RDF through NEB (T4) which is 23% higher than the yield of nutrients supplied through 100% RDF through inorganic fertilizers (T7). Since the nutrient supplied through NEB is released in a phased manner, it enhanced the uptake of nutrients and there by enhanced the yield of hybrid maize.
