Effect of NPK and Fym with Biofertilizer on Quality of Potato and Soil Nutrient Dynamics

An experiment was conducted at the Horticulture Research Farm, Janta College, Bakewar, Etawah during the Rabi season of 2022-23 and 2023-2024. Composite soil samples were collected in a zig-zag manner during the fallow period before the start of the experiment and after the harvesting of the crop. The experiment was laid out in a Randomized Block Design with ten treatments replicated thrice. PSB was used for seed inoculation. The objective of the study is to evaluate the effect of integrated nutrient management practices on the quality and soil nutrient status of potatoes. The results revealed that application of FYM @ 15t/ha + 1/2 of the recommended dose of NPK through chemical fertilizer resulted in maximum carbohydrate percentage. Application of FYM @ 30t/ha + 1/2 of the recommended dose of NPK through chemical fertilizer resulted in maximum proteins, TSS and sugars in potato as compared to other integrated nutrient management treatments. As far as soil nutrient status is concerned, different treatments recorded maximum organic carbon percentage, available N, P and K percentage. The results revealed that the application of integrated nutrient management with the application of FYM @ 30t/ha + 1/2 of the recommended dose of NPK through chemical fertilizer resulted in satisfactory quality parameters in potatoes.
