Abstract:
A field experiment was conducted at farmer’s field in Nainital district of Uttarakhand to know the response during 2021-2022 to know the response of potato variety Kufri Chipsona-2 to organic sources. The growth parameters and yield of potato were significantly influenced by the organic manures and chemical fertilizers. Maximum plant height (68.66 cm), number of haulms per hill (7.55), number of tubers per hill (8.33), weight of tuber per hill (626.66 g), dry matter content of tuber (26.30%), total soluble solids (5.03ᵒB). specific gravity (0.975 g/cm³) and yield (245.60 g/ha) were recorded with the application of 100% recommended dose of NPK (160: 100: 120 kg/ha)+10 t FYM followed by 100% of recommended dose of NPK alone. Maximum number and weight of A and B grade tubers were recorded in treatment T₄ and T₅, respectively. The highest net income as well as benefit: cost ratio (1.25) was obtained with the application of 100% NPK.
