Abstract
SUMMARY. The effect of early cropping (no blossom removal the firsttwoyears)and in-rowspacing at0.45 mand 1.2 m(1.5ftand 4ft)arebe-ing studied in ‘Duke’, ‘Bluecrop’, and ‘Elliott’ blueberries ( Vacciniumcorymbosum L.) planted in October 1999. No yield was produced on thenon-cropped plants in 2000 and 2001. In the early-cropped treatments,yield at 0.45 m was about three times that at 1.2 m in all cultivars in 2000and 2001. ‘Duke’ and ‘Elliott’ produced the highest yield in 2000. In2001, yield increased 8 to 16 fold at the 0.45 m spacing, depending on Bernadine Strik is Professor and Gil Buller is Research Assistant, Department ofHorticulture and the North Willamette Research and Extension Center, Oregon StateUniversity, 4017 ALS, Corvallis, OR 97331-7304 (E-mail: strikb@science.oregonstate.edu).The authors appreciate the financial support of the Oregon Blueberry Commissionand the Northwest Center for Small Fruits Research and the assistancefrom Fall CreekFarm and Nursery with plant costs.
