Estimating Vegetable Yields

Yields vary a great deal due to climate, growing conditions, soil quality, and farm management.  To estimate yield in a consistent manner, one can harvest 10' of row at several locations in the field. Multiply the average yield (lb) per 10' of row times the following row spacing factors to convert the sample yields to lb/A. See Table 14 and Table 15.

Table 14: Estimating Vegetable Yields

Row Spacing in Inches Multiply By

15 3480
18 2900
20 2610
21 2490
24 2180
30 1740
36 1450
42 1240
48 1090
56 930

NOTE: To convert yield per acre to yield per 100 feet of row:  multiply yield per acre by the number of feet between rows and divide by 4356.

* Yields vary depending on soil quality, weather conditions, farm management, location, etc. Low, Good and Excellent yields are based on national data, while 5-year averages (2017-2021) are from the USDA National Agricultural Statistics Service New England Vegetable Report and the USDA NASS New England Berries, Tree Fruit & Grapes Report
