A field experiment was conducted at the Agricultural Research Station, Siruguppa, University of Agricultural Sciences, Raichur, Karnataka, India, during the kharif 2025, to evaluate the effect of integrated application of the recommended dose of chemical fertilizers (RDCF), organic manures and biochar on the growth, yield, quality and economics of sweet corn (Zea mays var. saccharata L.). The experiment was laid out in a randomized complete block design with nine treatments replicated thrice, comprising RDCF alone and in combination with farmyard manure (FYM) at 7.5 t ha-1, vermicompost at 2.5 t ha-1 and biochar at 1 t ha-1, together with corresponding combinations under 75% RDCF and an absolute control. The application of RDCF + vermicompost (2.5 t ha-1) + biochar (1 t ha-1) recorded the significantly higher number of leaves per plant (12.53) and total dry matter production (194.25 g plant-1) at harvest, fresh cob yield (13,767 kg ha-1), green fodder yield (20,533 kg ha-1) and net returns (Rs 1,11,614 ha-1) and was statistically on par with application of RDCF + FYM (7.5 t ha-1) + biochar, RDCF + vermicompost (2.5 t ha-1) and RDCF + FYM (7.5 t ha-1). The same treatment also recorded the significantly higher total soluble solids (TSS) (13.82 °Brix) and protein content (8.19%). The higher benefit cost (B:C) ratio (2.42) was obtained with RDCF + FYM (7.5 t ha-1), owing to its lower cost of cultivation. The absolute control recorded the lower values for growth, yield and quality parameters. From this it is indicated that integration of RDCF with vermicompost and biochar is an effective nutrient management strategy for improving the productivity, quality and profitability of sweet corn under semi-arid tropical conditions.
