In one experiment, Cut to the eye potatoes grew much better. I have still not read that much on agricultural engineering. But my best wishes for several harvests. The study had 2 batch of potatoes one with whole and one cut. Roots might get soil easier than a whole potatoe with a few eyes. Will publish later. Hope it runs for several generations. Will read some books. Developing countries have some banking and stock problem affecting farmer security, which means I am trying to fix it.
