The Central Tuber Crops Research Institute (CTCRI) in Thiruvananthapuram has successfully demonstrated new high-yielding and pest-resistant varieties of cassava and Chinese potato (Sirukizhangu) in two villages in the district. The 'Sree Reksha' cassava variety is known for its high yield of 45 tonnes per hectare, good keeping quality, and resistance to cassava mosaic disease, while the Chinese potato variety 'Sree Dhara' provides a 50% higher yield than the local variety and has larger tubers with good keeping quality. These varieties have received positive feedback from farmers and are being distributed and cultivated more widely with the guidance of the Indian Council of Agriculture Research and the Department of Horticulture.
