Field experiment was conducted during rabi seasons of the years 2017-18 and 2018-19 to study the effect of NPK fertilizers on potato yield and its economics in North Gujarat Agro-climatic condition on loamy sand soils of Potato Research Station, Sardarkrushinagar Dantiwada Agricultural University, Deesa. The experiment was laid out by using Kufri Badshah cultivar in randomised block design with four replications comprising seven treatments viz., T1 : 50 % RDF of NPK, T2 : 100 % RDF of NPK, T3 : 150 % RDF of NPK, T4 : Without N fertilizer (PK), T5 : Without P fertilizer (NK), T6 : Without K fertilizer (NP), T7: Without NPK (absolute control). The Recommended dose of fertilizer (RDF) of potato at North Gujarat is 275:138:275 NPK kg/ha. Based on two years pooled data significantly the highest total tuber yield was recorded under treatment T3 (50.17 t/ha) which was at par with treatments T2 (49.26 t/ha) and T5 (46.71 t/ha). The crop fertilized with 100% RDF gave the highest net returns hence it is recommended to apply 100% RDF i.e., 275:138:275 NPK kg/ha for higher yield and net return
