Abstract: A field experiment was conducted during the Rabi season of the year 2017-18 on potato with variety Kufri Ashoka to test the recommended dose of fertilizers (RDF) levels (0, 50, 75, 100, 125, 150%) with two organic manures (vermicompost 5 t/ha and mustard oil cake 2.5 t/ha) at research farm of Tirhut college of Agriculture Dholi, Muzaffarpur, Bihar. The experiment was carried out in randomized block design (RBD) with twelve treatments and replicated thrice. The soil of experimental plot was Entisols, sandy loam in texture under low available in N, P and K with pH 8.3. Among the bulking rate, grade wise yield and yield were recorded higher with the application of treatment T₁₁ - 150% RDF + 5.0 t/ha vermicompost which was significantly superior over T₁, T₂, T_3, T₄, T₅ and T₆ but was statistically at par with treatments, T₇, T₈, T₉, T₁₀ and T₁₂.
