Abstract
An experiment was conducted to study the effect of different sources of sulphur (Elemental sulphur, gypsum and pyrites) on the uptake of nutrients by sunflower genotypes. The uptake of N, P, K, S and sulphur use efficiency by shoot at 45 DAS, harvest stage and by seed was significantly more with the gypsum > pyrites > elemental sulphur. The genotypes also significantly differed in the uptake. More nutrient uptake was observed in Ganga kalyani-2002 than 6460 PH-1.
