i hope this helps some jdsims. this a rough estimate from some of the things i plant.
ROUGH YIELDS PER PLANT !
1. TOMATO--DETERMINATE VARIETY-- 2-5 LBS.
2. CHERRY TOMATO-INDETERMINATE- 2-3 QUARTS
3. TOMATO-INDETERMINATE VARIETY/STAKED-4-10 LBS.
4. GREEN BEAN-(1/2 TO 1 LB.)
5. ZUCCHINI-- 4-8 ZUCCHINI
6. CUKES--MARKETMORE76--(3-6 PER PLANT)
7. PICKLE--SMR58--(2-3 QUARTS)
8. GREEN PEPPER--(4-8 PEPPERS)
9.PEAS-GREEN ARROW (.5 TO 1.5 QUARTS)

THESE ARE MY ESTIMATES ,WITH PROPER PICKING, AND SPACING.
REMEMBER IF YOU DONT PICK CUKES,ZUCCHINI. THE FRUITS GET OVERRIPE AND THE PLANT WILL SHUT DOWN.
I HOPE THIS INFO HELPS,MARK
