Recently met Vinod from Puthanchira, Thrissur in a meeting where he was presenting his tuber collections. Apparently he has a wide collection of tubers - taros, elephant foot yams,air-potato,tapioca, ginger, turmeric, kachil (malayalam name,english name to be found out). There is another tuber farmer in Wayanad called Samuel, and Vinod is a disciple of him.
I gave him the variety of taro I had, and he gave me a set of tubers in return. It is a big responsibility to preserve them, had asked him to provide only one or two, but he just gave me a number of varieties. Will be starting planting them with rain.
Some varieties ...
