Attached is a yield table I have worked on. The sources are varied, but the main portion is from a book on intesive gardening. Remeber that the more you try to grow, generally the yield per unit becomes less (diminishing returns). The less is more concept is true. For yields of vegetables, I generally take 50% as the base yield. Then adjust with perctile increase or decrease from that.

Remeber diversity and crop rotations are essential for good sustained production. Animals add to the production cycle, eating waste and giving back produce and variety in diet.

CODE:

sp/in is the spacing of the plants in inches (recall this is intense gardening from the start)
y/plt is the yield in pounds per plant
4x20 is the number of plants at the recommended spacing in a 4' x 20' bed
yield is the yield in pounds of a 4x20 bed
y/0.1a is the yield in pounds of 1/10 acre plot

It should be noted the 1/10 plot for vegetable is ambigious as you need more walk space, which takes up approxiomately 1/3 of the total area.


hope you can find some use. As for the field crops, they are amgigious and I would use 1/3 of the yield given lacking other data for post-oops base line. Work is on going.
