Abstract:
A field experiment was carried out at Student Instructional farm, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Ayodhya (U.P.) during Rabi season 2017-2018 to evaluate the effect of Zinc fertilization with different nutrient management practices on the soil properties and availability of nutrients under potato (Solanum tuberosum L.) crop. The five treatments comprised with various levels of 75% and 100% recommended doses of NPK, ZnSO4 (20, 30and 40 kg ha^-1) and 25% Nitrogen by Farm yard manure were tested against 100% NPK fertilizers alone were replicated four time in randomized block design (RBD) potato crop the variety Kufri Baadshah was taken a test crop. The result revealed that there was improvement in the soil physico-chemical properties and increase in the availability of nutrients in all the treatments wherever organics were the components of the treatments. Among all the treatments, treatment consisting of 75% recommended dose of NPK fertilizers with 25% nitrogen by the farm yard manure as well as 40 kg/ha ZnSO₄ (T₅) was found most superior in improving the physicochemical properties of the soil as well as increasing the availability of nutrients.
