Effect of Quality Attributes of Potato by Using Biochar and NPK Fertilizers with Biozyme Granules

The present study, which took place at the central Research Farm of Naini Agricultural Institute, SHUATS, spanned across the years 2022-2023 and 2023-2024. Throughout this study, an experiment was meticulously conducted utilizing a variety of Kufri badhash under the Factorial Randomized Block Design (FRBD) design. This experiment included three replications, each encompassing three levels (2.5, 5, 7.5 t ha-1) of Biochar and three levels (50%, 75%, 100%) of Inorganic fertilizers. Additionally, two levels (25 and 50 kg ha-1) of Biozyme granules were also part of this comprehensive research design. The results obtained regarding various quality parameters in the years 2022-23 and 2023-24, such as moisture content (80 and 81 100g-1), tuber dry matter content (20.98% and 21.96 %), starch content (13.54% and 14.12%), reducing sugar (0.28% and 0.30%), non-reducing sugar (0.35% and 0.37%), and total sugar (0.58% and 0.59%) were notably elevated with the application of T16. Notably, the maximum protein content (2.07 and 2.31%), carbohydrate (14.58% and 14.85%), and total soluble solid (6.44% and 6.77%) were observed with the application of T18 in accordance with the recommended practices. Conversely, the minimum values were recorded for T1, showcasing the significant impact of the application techniques on the various parameters studied.
