During the Zaid season of 2025, a field study titled "Effect of Phosphorus and Sulphur on growth and yield of Greengram (Vigna radiata L.)" was carried out at the Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.). The experimental field soil had a sandy loam texture, a moderately basic response (pH 7.2), medium levels of available organic carbon (0.310%), low levels of available nitrogen (269.75 kg/ha), and extremely high levels of available potassium (246.4 kg/ha) and phosphorus (18.0 kg/ha). The experiment was laid out in a Randomized Block Design (RBD) with ten treatments and replicated thrice viz., T₁: Phosphorus 30 kg/ha along with Sulphur 20 kg/ha, T₂: Phosphorus 40 kg/ha along with Sulphur 30 kg/ha, T₃: Phosphorus at 50 kg/ha along with Sulphur 40 kg/ha, T₄: Phosphorus 30 kg/ha along with Sulphur 20 kg/ha, T₅: Phosphorus 40 kg/ha along with Sulphur 30 kg/ha, T₆: Phosphorus 50 kg/ha along with Sulphur 40 kg/ha, T₇: Phosphorus 30kg/ha along with Sulphur 20 kg/ha, T₈: Phosphorus 40 kg/ha along with Sulphur 30 kg/ha, T₉: Phosphorus 50 kg/ha along with Sulphur 40 kg/ha and T₁₀: RDF: 20:40:60 NPK kg/ha as control. The result sowed highest plant height (48.80 cm), plant dry weight (30.38 g), and number of nodules (22.47) were all considerably greater with (T₉) phosphorus 50 kg/ha and sulfur 40 kg/ha. It was determined that applying phosphorus and sulfur together resulted in a noticeably larger number of growth parameters and Greengram production.
