Abstract:
An experiment was conducted at ICAR-KVK, Kalaburagi during the Kharif season of 2022. The Experiment was laid out in RCBD with Eight treatments which were replicated thrice. The experimental results revealed that, soil application of (RDF) + 20 kg ha^-1 sulphur + 10 kg ha^-1 zinc sulphate through chemical fertilizers recorded significantly higher removal of nitrogen by cowpea crop (88.03 kg ha^-1), phosphorus (20.87 kg ha^-1) potassium (58.70 kg ha^-1) sulphur (14.19 kg ha^-1) and zinc (0.171 kg ha^-1) was recorded. Which was on par with (RDF) + 10 kg ha^-1 sulphur + 5 kg ha^-1 zinc sulphate. In contrast lower value for removal of nutrients by cowpea crop recorded in absolute control. Hence, for effective management of sulphur and zinc, the application of RDF + 10 kg ha^-1 sulphur + 5 kg ha^-1 zinc sulphate was recommended.
