Additional Details

The outdoor production trial, conducted from September through December 2022, was a completely randomized data collection of six replicates. A Portola strawberry variety was grown. At planting, all treatments received controlled release fertilizer and in-season applications of nitrogen and phosphorous, along with seasonally necessitated foliar pest control. The trial was conducted at a research farm in Ventura County, California.
