Effect of nitrogen and sulphur levels on yield and economics of cluster bean (Cyamopsis tetragonoloba L.)

Abstract

A field experiment was conducted during Kharif season 2023 at Crop Research Farm, Department of Agronomy. Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh. The treatments consisted of three levels of Nitrogen (10, 15 and 20 kg/ha) and three levels of Sulphur (20, 25 and 30 kg/ha) along with control (20-40-20 NPK kg/ha). The experiment was laid out in a Randomized Block Design with ten treatments which have replicated thrice. The results of the experiment revealed that the Application of Nitrogen at 20 kg/ha along with Sulphur 30 kg/ha (Treatment 9) recorded significantly higher Seed yield (1.69t/ha), higher Stover yield (3.27t/ha) and harvest index (33.13%). The same treatment also recorded maximum gross return (INR.79332.07 /ha), net return (INR. 55152.07 /ha) and benefit cost ratio (2.28).
