A field experiment was conducted during karif 2011 at Shirol village of Nargund taluk in Gadag district to study the effect of levels and ratios of nitrogen and sulphur fertilizers on growth and yield of maize (zea mays L.) under irrigation. The experiment was conducted in vertisol by adopting randomised complete block design (RCBD) with three replication and fourteen treatment combinations. Application of nitrogen and sulphur fertilizers @ 150: 30 with a N: S ratio of 5:1 was found superior in terms of plant height, number of leaves per plant, dry matter production, number of grains per row, grain number per cob and grain weight per cob over other treatments. Similarly, the highest grain yield of 75 q/ha and straw yield 9.30 t/ha was recorded with the application of 150 kg N and 30 kg S per hectare with an N: S ratio of 5:1.
