Nutrient content and uptake of soybean (Glycin max L meril) on different fertility levels under guava based agrihorticulture system

A field experiment was carried out at Banaras Hindu University, Mirzapur in kharif season 2018 to study about effect of different fertility levels on nutrient content and uptake of soybean under guava based Agri horticulture system. There were five fertility levels in a randomised block design. The sources of fertilizers were urea, DAP, MOP and elemental sulphur for N, P₂ O₅, K₂ O, and S application, respectively. The variety of soybean was JS-2029, inoculated with rhizobium culture. Among the different fertility levels the application of 50 kg N, 100 kg P₂ O₅, 60 kg K₂ O, and 40 kg S ha^-1 with rhizobium inoculation significantly enhances the nitrogen, phosphorus, potassium and sulphur content and uptake in grain and straw of soybean.
