Popis: Foliar applications of boron (B) have been shown to increase fruit set and yield of several woody fruit species, but there have been no reports of foliar B effects on blueberry (Vaccinium corymbosum L.). The objective of this study was to determine if foliar B would decrease tip dieback, alter yield components, and increase berry yield of blueberry. Blueberry plants (cvs. Collins and Blueray) were grown on a Menfro series soil (fine‐silty, mixed, mesic Typic Hapludalf) with the two cultivars planted in alternate rows. Five uniform plants from each row were either treated with foliar B plus surfactant or untreated. Foliar B was applied in the fall prior to each harvest year, 1990 through 1993, and additional foliar B was applied in the spring in 1991 through 1993. Foliar B increased blueberry weight/plant by 10% over the four‐year period. The increase in blueberry yield was a result of a 12% increase in number of berries/plant. Yield increase following foliar B treatment was greatest during the fi...
