The present investigation was carried out at Student Instructional farm Narendra Deva University of Agriculture and Technology Narendra Nagar Kumarganj, Ayodhya (U.P.) during Rabi season 2017-2018. To evaluate the Effect of nutrient management practices on the performance of potato (Solanum tuberosum L.) and soil fertility. 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 KufriBaadshah was taken a test crop. Results revealed that the integrated use of 75% recommended doses of NPK fertilizers (180:80:100), 25% nitrogen by Farm yard manure as well as 20kg ha-1 ZnSO4 in potato was found superior for higher plant growth, productivity and better marketable quality of tubers. The availability of NPK nutrients, organic carbon, moisture retention capacity of soil increased while bulk density, soil pH, and electrical conductivity decreased at higher rate by applying 75% recommended doses of NPK and 20kg ha-1 ZnSO4 fertilizers with Farm yard manure as compared to 100% recommended doses of NPK fertilizers alone. The application of 75% recommended doses of NPK, 20 kg ha-1 ZnSO4 fertilizers and 25% Nitrogen by Farm yard manure provided highest net returns (Rs. 193639) and cast benefit ratio (2.48). It was concluded that application of 75% RDF, 20 kg ha-1 ZnSO4 fertilizers and 25% nitrogen by Farm yard manure may be recommended for higher productivity and returns, and build up soil fertility.
