Abstract: Field investigations were carried out during March 2012 and August 2012 at Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar, to study the effect of Integrated sulphur management practices on the yield, quality, nutrient uptake and nutrient availability of hybrid sunflower cv. sunbred. The experiments were laid out in randomized block design and replicated thrice. The experiment consisted of eleven treatments viz., T1 – No sulphur / RDF alone (control), T2 – 45 kg S ha-1 through gypsum, T3 - 45 kg S ha-1 through vermicompost, T4 - 45 kg S ha-1 through poultry manure, T5 - 45 kg S ha-1 through lignite flyash, T6 - 75 % S ha-1 through gypsum + 25 % S ha-1 through vermicompost, T7 - 75 % S ha-1 through gypsum + 25 % S ha-1 through poultry manure, T8 - 75 % S ha-1 through gypsum + 25 % S ha-1 through lignite flyash, T9 – 50 % S ha-1 through gypsum + 50 % S ha-1 through vermicompost, T10 – 50% S ha-1 through gypsum + 50% S ha-1 through poultry manure and T11- 50% S ha-1 through gypsum + 50 % S ha-1 through lignite flyash. The results of the experiments revealed that application of 75 % S ha-1 through gypsum + 25 % S ha-1 through vermicompost (T6) significantly influenced the yield, quality, nutrient uptake and nutrient availability in sunflower. This treatment also recorded higher values for yield attributes viz., total number of seeds head-1 (778.06 and 815.26), number of filled deeds head-1 (634.45 and 672.28), seed filling percent (83.04 and 84.26 %), seed yield (1825.46 and 1927.39 kg ha-1) and stalk yield (3800.63 and 3898.59 kg ha-1) in both the crops. This treatment recorded maximum N,P,K and S uptake, maximum oil content, oil yield and crude protein content in both the crops. This was followed by T7 (75 % S ha-1 through gypsum + 25 % S ha-1 through poultry manure) in both the crops. The lowest values for yield, quality, nutrient uptake and nutrient availability were recorded in T1-No sulphur / RDF alone (control) in both the crops. T1 recorded Maximum N,P,K and S availability in both the crops.
