Condensed harvest window on blueberries
When plants have a surplus of energy, reproductive buds are all large and uniform in size, blossoms all pollinate at the same time, and fruit all mature in a condensed window. For machine-harvested blueberries, this can mean harvesting 90% of the crop in a single pass. For fresh-market, hand-picked berries, this can mean harvesting the entire crop in 4-6 passes over as many weeks. You can calculate the increased labor efficiency and reduced harvest costs.
