Blueberry yield calculator

The yield calculator is based on the following assumptions:

1. Cultivar specific data are based on an eight-year study conducted at the North Willamette Research & Extension Center, Aurora, Oregon (Bernadine Strik, 2015). Results may vary for other cultivars and production regions.

2. The calculator works best for younger plants – bud number has been found less related to yield in older plants, because the type of fruiting wood is more variable (Strik, 2012).

3. Results are improved if you enter your own results for the number of flowers per bud, percent fruit set, and average berry weight for each cultivar grown – keep yearly records on your your farm to improve accuracy.
