Which vegetables? That is mostly for you to decide. The source of the table in the file is Extension Bulletin 422 from the Cooperative Extension Service of the College of Agriculture at Washington State University, Pullman, WA. This bulletin was reprinted in 1970 from an earlier document and utilizes the row crop methodology. One can easily reduce the space requirements by the use of raised beds/intensive interspacing. There was one unit of measure I am not sure of and that is the abbreviated unit "bu" used for the potatoes. Bu stands for bushel, but it is not an easy unit to grasp so - for 150 feet of potatoes planted at 12 inch spacing, one needs 150 potato "eyes" or about 50 potatoes.
