The study was undertaken to assess the performance and efficiency of Nitrogen and Sulphur and their interaction in their

respective doses applied through urea and elemental sulphur on sunflower (Hellianthus annuus L.). Full dose of sulphur was

given before sowing where as half nitrogen was applied at the time of sowing and next half nitrogen was applied at the age of

40 days after sowing. Besides this, Neem cake@2 q.ha-1 was also applied to check the termites and nematodes in soil. As

regards height of plant at 30, 60 and 90 days, T10 (N120S80) treatment combination followed by T9 (N120S40) have produced

tallest plants and increase in doses of N and S have significantly accelerated the total biomass and yield.
