A good crop mi amigo! Those are very big cassava roots. Here in Canada we import cassava starch and flour. Some breads and food products are made with it. But it is not a huge staple like it is in the tropics, including Venezuela.

Can you tell me, do those roots grow straight down? In other words, is it like a carrot, with the tip of the root deepest in the soil? If so, that is a very deep plant! You must have excellent soil.
