Abstract

An experiment on response of sunflower to different levels of nitrogen and sulphur was conducted during kharif 2011. The increase in the plant height, number of leaves/plant, leaf area index, dry matter accumulation and stem girth were significant with each increment of nitrogen upto 120 kg/ha and sulphur upto 30 kg/ha. Application of 120 kg N/ha registered higher seed yield (2108 kg/ha) over 60 and 90 kg N/ha. Among the sulphur treatments, application of 30 kg S/ha recorded highest seed yield (2048 kg/ha) over 0 and 15 kg S/ha. Application of 120 kg N/ha recorded maximum stalk yield (4072 kg/ha) over 60 and 90 kg N/ha, while the lowest stalk yield (3638 kg/ha) was observed in plots fertilized with 60 kg N/ha. Application of 30 kg S/ha recorded more stalk yield (4028 kg/ha), whereas low stalk yield (3696 kg/ha) was observed in plots with no sulphur application. Quality parameters viz., oil content, oil yield and protein yield were significantly higher with higher levels of nitrogen (120 kg/ha) and sulphur (30 kg/ha).
