No, they are the full dragged rectangle up to 11x11 
, meaning that I have those empty rows between the crops. (for the corn and wheat, that is 3 farms)
Except on the case where I mentioned I used one row of each food type, in that case, it is exactly that, a single 11x1 row of a food, than another of other food, etc… But summing it all, it is almost equivalent to another default 11x11. (a 11x11 has 6 rows of crops, I have 1 for pumpkin, 1 turnip, 1 gourd, 1 watermelon, and 3 carrots)
This with 2 farmers and 3 cooks is perfect for me. (the cooks barely help in the farms though, they are too busy cooking, maintaining 20 orders of each food recipe is hard, they barely stop)
