Field experiments were conducted during 2010 and 2011 in a farmer’s field at Sivagangai district, Tamil Nadu to evaluate the effect of inorganic S alone and in combination with organic manures on hybrid maize. The results revealed a positive effect for the application of S alone and in combination with organic manures. The highest grain yields of 5980 and 6025 kg ha-1 were registered with the application of vermicompost conjoint with 80 kg S ha-1 during the year 2010 and 2011, respectively. A marked improvement on uptake of N,P,K and S were observed with the increase in the level of S. Among the organics, application of vermicompost was better followed by press mud and FYM. Application of organics and inorganic S significantly improved the available P, K and S status of the soil .The available N content of the soil was not increased due to the application of organics and inorganic S.
