Field Pea Yield Estimates
Field pea seed yield potential appears very favorable this season. If you are interested in estimating pea yield before harvest, the following procedure may be used.
Step 1. Hand thresh and count the number of seeds contained in a square foot area.
-- sample several square foot areas of the field and average the number of seeds to increase the confidence in the estimate.
Step 2. Estimate the number of seeds per lb. for the variety grown.
Step 3. Use the numbers from steps 1 and 2 in the formula:
(seeds per sq ft X 43,560) /(60 X seeds per lb) = estimated yield per acre.
Example:
A 'Profi' field was sampled at several locations and the average seeds per sq ft was 125. Assume the number of seeds per lb is 1800 (seed count data may be obtained from the Research Extension Center annual reports) (125 X 43,560) / (60 X 1800) = estimated yield of 50 bu per acre.
