Abstract: A field experiment, entitled “Evaluation of different fertilizer coating materials to increase Nitrogen use efficiency in potato (Solanum tuberosum L.)” was conducted at the Research Farm of ICAR - Central Potato Research Station, Gwalior (M.P.) during Rabi season of 2015-16. The experiment was laid out in randomized block design with 12 treatments replicated three times. The results revealed that 100% RDF N coated with Neem cake 5% produced significantly higher plant height (50.20 cm), number of leaves/plant (80.13), stem/plant (5.00) at 60 DAP, however fresh ( and dry weight of tuber (g)/plant, tuber number /plant, nitrogen use efficiency, NPK content in soil (kg/ha), NPK % in both tuber and haulm, NPK uptake (kg/ha) by crop, yield (tuber, haulm and biological in kg/plot as well as q/ha). The maximum net return (68.7 Rs.’000) and benefit: cost ratio (1.85) was obtained under100% RDF N coated with Neem cake 5%. Further application of 100% RDF N coated with pond soil (clay) 5% recorded higher net return (Rs. 45.6 Rs.’000). Therefore, 100% RDF N coated with Neem cake 5% followed by 100% RDF N coated with pond soil (clay) 5% are the most suitable coating material to increase N use efficiency in potato crop.
