In the paper entitled, Influence of plant spacing on yield of muscadine grape by W. T. Brightwell and M. E. Austin (J. Amer. Soc. Hort. Sci. 100(4):374-376, 1975), the figure in Table 2, Year 1955, 20.1 square meters, 435 plants/ha should read 9.8a instead of 26.8a and the avg for the same column should read 29.0ab instead of 29.6ab.
Hedging reduced yield and increased fruit size of rabbiteye blueberry (Vaccinium ashei, Reade) for one or 2 years following hedging, but yields and fruit size were similar to unhedged plants after 4 years. The best hedging treatment time was February, with evaluation taking place over a 5-year period following hedging.
One-wire, 2-wire, and overhead trellis systems of the muscadine grape, Vitis rotundifolia, Mich., cv. Hunt, were compared for 20 bearing years. Initially, plants trained to the 2-wire trellis had the highest yield; but for each of the next 18 years, the highest yield was obtained from the overhead trellis. All training systems exhibited alternate bearing after the 7th crop year. The alternate bearing pattern was the same as the state pecan production.
Plants set 6.1, 6.4 and 6.7 m apart in each of 3.0-, 3.7- and 4.3-m rows of the muscadine grape, Vitis rotundifolia, Michx., cv. Hunt, were compared for 25 years. The highest plant density, 477 plants/ha, gave the greatest yield per m2 almost consistently for 25 years. The highest yields per plant were obtained from the wider in-the-row spacings. Alternate bearing was rather consistent from 1949 through 1963, but irregular thereafter.
Rabbiteye blueberries (Vaccinium ashei Reade, cvs. Tifblue and Woodard) were fertilized with various ratios of nutrients for 6 years. ‘Tifblue’ responded to 4–8–8 (4.0 N–3.5 P–6.6 K), 5–10–10 (5.0 N–4.4 P–8.3 K), and cottonseed meal 7–2–2 (7.0N–0.9P–1.7K). ‘Woodard’ did not respond to any fertilizer.
