Effect of sulphur and boron on growth and yield of soybean

A field experiment was conducted at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, UP, during the Kharif season of 2023. The experiment was laid out in Randomized Block Design with ten treatment combinations and three replications in which there were three levels of sulphur (10,20 and 30 kg/ha) and three levels of boron (0.5, 01 and 1.5 kg/ha) and a control (25-60-25 NPK kg/ha). Among the various treatment combinations significantly highest plant height (50.92 cm), dry weight (17.58 g), pods/ plant (29.00), seeds/pod (2.93), test weight (88.06 g), seed yield (2.06 t/ha), stover yield (3.42 t/ha) and oil content (20.09%) were recorded in treatment-9 with application of sulphur 30 kg/ha + boron 1.5 kg/ha. Maximum gross returns (82,243.33 INR/ha), net return (54,332.40 INR/ha) and benefit cost ratio (1.95) were also obtained in treatment-9 with application of sulphur 30 kg/ha + boron 1.5 kg/ha in soybean crop.
