Raising awareness about the benefits of organic food has spurred consumer demand and organic farming practices. However, organic farming often criticized for its lower productivity than conventional farming. Poorly adapted varieties are partially responsible for the lower yields in organic farming. Therefore, it's crucial to identify suitable varieties for organic farming to minimize the yield gap between organic and conventional farming practices. To address this, a field experiment was conducted at Indian Council of Agricultural Research (ICAR)-Central Potato
Research Institute (CPRI), Regional Station, Shillong, during the kharif seasons of 2020 to 2022. The study evaluated the performance of six potato varieties viz., Kufri Jyoti, Kufri Megha, Kufri Giriraj, Kufri Kanchan, Kufri Himalini and Kufri Girdhari under organic farming. The findings indicated that Kufri Himalini is suitable for organic cultivation, exhibiting the highest total tuber yield (14.44 t ha-1) combined with marketable tuber yield (10.89 t ha-1). This variety has moderate resistant to late blight and medium tuber dormancy. Storage behaviour varied among the varieties.
Tubers of Kufri Girdhari and Kufri Kanchan were exhibited excellent keeping quality with long tuber dormancy and minimum storage losses, indicating their suitability for low-cost country storage for six months.
