Abstract

Mother block plantings of 6 cultivars of highbush blueberry (Vaccinium corymbosum L.) for the production of cutting wood were successfully grown at 30.5 × 30.5 cm spacings on a Berryland soil. At this spacing 4- and 5-year-old ‘Bluecrop’ plants produced at the rate of 5.27 million cuttings per ha. Cutting wood production increased with increasing N fertilization. Optimum rate of N application was in excess of 45 kg N/ha. Application of fungicide under certain conditions increased weight per cutting.
