Abstract
Efficiency of three sulphur sources, viz: ammonium sulphate, single superphosphate and gypsum was evaluated under field conditions for their influence on growth and yield of PARC-92E and Hysun-33 hybrids of sunflower. Sulphur from the three sources was applied @ 0 and 37 kg S /ha. The two sunflower hybrids responded differently to S application from the three sources because there was a significant (p < 0.05) hybrid x sulphur source interaction. Response of the two sunflower hybrids to the three sources was in the order of ammonium sulphate > single superphosphate > gypsum. The sunflower hybrid, PARC-92E responded better than Hysun-33 to S application.
