Response of Different Levels of Nitrogen and Sulphur on Production and Economics of Sunflower (Helianthus annuus L.)

Abstract

A Field Research done at Sam Higginbottom University of Agriculture, Technology, and Sciences in Prayagraj, Uttar Pradesh in Kharif to study the interactive effect of different levels of Nitrogen and Sulphur on yield and economics of sunflower (Helianthus annuus L.) var. DRSH -1. Experiment was undertaken on an agricultural research farm in 2021. Nitrogen is a primary nutrient element which plays a major role in growth and development of plant and As Sunflower is an oilseed crop, requires optimum level of Sulphur to produce good quality oil. Thus optimum levels of Nitrogen and Sulphur increases the production and productivity of sunflower crop. A combination of 120 kg N/ha + 45 kg S/ha yielded the maximum Seed yield (1446.20 kg/ha), Stover yield (2794.39 kg/ha), the highest gross return (94.003 x 103 INR/ha), net return (58.619 x 103 INR/ha), and benefit: cost ratio (B:C ratio) (1.66).
