Objective of this study was to investigate the effect of the integrated nutrient management on growth,yield and quality of Potato (Solanum tuberosum L.). Continuous application of chemical fertilizers causes nutritionalimbalance and adverse effects on the physico-chemical and biological characters of soil. Thus, an integrated nutrientsupply by chemical fertilizer along with organic manures is given importance, especially in heavy feeder crops likepotato. The experiment was conducted at PG Research Farm of M.S. Swaminathan School of Agriculture, CenturionUniversity of Technology and Management, Paralakhemundi, Odisha during rabi season of 2023-24 under the sandyclay loam soil with an altitude of 90 m above the mean sea level. The experiment was laid out in randomized completeblock design (RCBD) with three replications and eight treatments: 100% recommended dose of nitrogen (RDN)(T1), 90% RDN + 10% N through farm yard manure (FYM) (T2), 90% RDN + 10% N through vermicompost (T3), 80% RDN+ 20% N through FYM (T4), 80% RDN + 20% through vermicompost (T5), 70% RDN + 30% through FYM (T6), 70% RDN+ 30% through vermicompost (T7) and control (without any chemical fertilizer or organics) (T8). The application of 100%RDN resulted in a significant increment till harvest in terms of growth parameters over the control. A significant increasein total tuber yield (239.1%), starch content (8.7%), carbohydrate content (15.8%), net return (17.26 times) was also observedunder 100% RDN when compared to no chemical or organics application. Treatments integrating 90% RDN with organicamendments such as farm yard manure (FYM) and vermicompost closely matched the performance of 100% RDN. Thestudy advocates for a balanced use of chemical and organic fertilizers, emphasizing the importance of optimizing nutrientmanagement to achieve sustainable agricultural practices that ensure high productivity, quality and economic profitability.
