A field trial was conducted in the research farm of ICAR-Indian Agricultural Research Institute, Assam as well as in the farmer’s field in Mohori Camp, Gogamukh, Dhemaji, Assam to evaluate the potato varieties under the organic management system during the rabi season of 2023-24.
The soil is acidic in reaction (pH of 5.65) and the texture of the soil is sandy. The soil had medium soil organic carbon content. The well-decomposed farmyard manure (FYM) was applied at 10 t/ha as a nutrient source. Three potato varieties viz., Kufri Himalini, Kufri Giridhari, and Kufri Giriraj were used for field trial. The results showed that Kufri Himalini registered 21.0 t/ha potato tuber yield followed by Kufri Giriraj (18.5 t/ha potato tuber yield) and Kufri Giridhari (16.8 t/ha tuber yield). Further, on average Kufri Giriraj registered 116.0 g single potato weight followed by Kufri Himalini (115.7 g) and Kufri Giridhari (93.7 g). The average potato tuber size was 6.5 cm (length) × 4.2 cm (width) in Kufri Giriraj followed by 6.0 cm (length) × 4.4 cm in Kufri Himalini and 5.2 cm (length) × 3.8 cm in Kufri Giridhari.
Therefore, Kufri Himalani, Kufri Giridhari, and other suitable potato varieties can be promoted for cultivation under an organic management system to enhance the farmer’s income and nutritional security.
