This study is carried out to assess the sulphur and boron nutrient dynamics in soil and its effect on seed yield of soybean under rainfed situation in northern Karnataka. An experiment was conducted during Kharif 2014 and 2015 at Agricultural Research Station, Janwada, Bidar, comes under University of Agricultural Sciences, Raichur, Karnataka, India. Application of recommended dose of fertilizer + 12 kg ZnSO4/ha + 30 kg Sulphur/ha +1.0 kg Boron/ha recorded significantly (p=0.05) higher seed yield (22.7 q/ha) and which was onpar with the application of recommended dose of fertilizer + 12 kg ZnSO4/ha + 30 kg Sulphur/ha +1.5 kg Boron/ha (21.5 q/ha) compared to other treatments. Further, significantly (p=0.05) higher uptake of nitrogen (163.0 kg/ha), phosphorus (18.5 kg/ha), potassium (74.61 kg/ha), sulphur (22.16 kg/ha) and boron (0.14 kg/ha) were recorded in the treatment with the application of recommended dose of fertilizer + 12 kg ZnSO4/ha + 30 kg Sulphur/ha +1.0 kg Boron/ha and which was onpar with the application of recommended dose of fertilizer + 12 kg ZnSO4/ha + 30 kg Sulphur/ha +1.5 kg Boron/ha (160.5, 16.48, 73.19, 20.12 and 0.12 kg/ha, respectively. Application of recommended dose of fertilizer (40:80:25 kg NPK/ha) + 12 kg ZnSO4/ha + 30 kg Sulphur/ha +1.0 kg Boron/ha was increases the seed yield of soybean and uptake of nutrients under northern Karnataka.
