During the summer of 2020, on farm evaluation was carried out on the College Agronomy Farm of Anand Agricultural University, Gujarat. A significant effect of sulphur fertilizer was observed in raising crop yields of cluster bean. The ideal sulphur dose for maximizing yield and making a profit over fertilizer cost was obtained using a quadratic model of the connection between cluster bean seed yield and the sulphur dose applied. Using information from field trials conducted in 2020, the ideal sulphur dose in cluster bean cultivation under middle Gujarat conditions was determined. For cluster bean, the economically ideal sulphur dose was discovered to be 43.63 kg/ha under middle Gujarat conditions in 2020. When sulphur was over-fertilized for maximum production, the seed yield was nearly identical, even at the physical and economic optimum dose of sulphur, resulting in a 1.55 kg/ha reduction in sulphur use.
