Abstract: A field experiment was conducted during rabi 2014-2015 on clay loam soil at irrigated upland farms of Eastern block, Tamil Nadu Agricultural University, Coimbatore to study the effect of integrated nitrogen management on kernel quality of sweet corn hybrid. The experiment was replicated thrice, with 12 treatments comprising integration of organic manures viz., FYM, vermicompost, poultry manure, goat manure and biogas slurry at 2 levels (25 and 50 percent) with inorganic N at 75 and 50 per cent. The remaining two treatments were 100 per cent N as inorganic fertilizer and 100 per cent N as inorganic fertilizers with 12.5 t ha^-1 of FYM. Application of 25 per cent N as poultry manure with 75 per cent N as inorganic improved the quality parameters of sweet corn kernel viz., sugars, starch, protein, total soluble solids, phenol and calcium. It was comparable with the application of 25 per cent N as goat manure combined with 75 per cent N as inorganic fertilizer.
