Application of phosphorus and elemental sulphur is an important tool to obtain high yield of green gram (Vigna radiata L.) under teak based agroforestry system in kharif season 2014 and 2015. The overall goal of the present experiment was to assess the impacts of phosphorus and elemental sulphur application on green gram growth under teak based agroforestry system in eastern Uttar Pradesh, India. Green gram was grown in an alley cropping system, which integrates trees with grain crops. Specific objectives of the study were to: (a) determine theeffect of phosphorus and sulphur on growth of green gram under teak based agroforestry system during Kharif season; (b) evaluate the interaction effect between phosphorus and sulphur levels, if any(c), to find the effect of phosphorus and sulphur levels on nutrient content and uptake by green gramunder teak based agroforestry system during kharif season. The impacts on green gram growth were assessed for different rates of phosphorus (25, 45 and 65 kg/ha) and S (20, 35 and 50 kg/ha) under teak based agroforestry system during kharif season. The field experiment was laid out according to a factorial randomized block design with three replications of 9 treatment combinations. Application of phosphorus at 65 kg/ha produced the best results in terms of the green gram growth attributes like plant height, number of trifoliate leaves/plant, dry matter accumulation, number of nodules/plant, CGR, RGR and NPKS content and uptake by crop compared with the phosphorus at 45 kg/h and 25 kg/ha under both condition open and teak based agroforestry system. However application sulphur at 50 kg/ha also gives higher growth and nutrient content and uptake by the crop as compared with S35 kg/ha, S 20kg/ha in both condition open and teak based agroforestry system.
