Effect of Organic Sources on Growth, Yield and Quality of Potato Raghav M., Kumar Tarun, Kamal Shashi Department of Vegetable Science, College of Agriculture, G.B.P.U.A.& T., Pantnagar-263145, U.S. Nagar, Uttarakhand (India) Abstract A field experiment was conducted at Vegetable Research Centre Pantnagar, Uttarakhand during 2003–04 and 2004–05 with potato cultivar K. Chipsona-2. 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 (5.03°B), specific gravity (0.975 g/cm3) and yield (245.60 q/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) were obtained with the application of 100% NPK. Top Keywords Organic nutrition, FYM, vermicompost, potato. Top |
