http://www.durgan.org/ShortURL/?DMKNV 18 July 2008 Superior Potatoes. Comparing chitted to Not Chitted Plants. Two plants were compared as to the production of the potatoes produced, one seed potato was chitted, and the other was not. At first look, visual inspection indicates that the chitted plant produced larger tubers. I have 18 more plants to compare, so will have a better idea as to the merits of chitting potatoes.
