| Abstract:
To balance cost and benefits of rain covers for sweet cherries, superintensive culture was tried. The first experiment was done in a glasshouse with potted trees that were spaced at 0.33 by 1.5 m (20,000 trees/ha). Yields of 6 to 9 tons/ha were reached in the 3rd leaf and, by the 7th leaf, production had reached 16 to 38 tons/ha. Slender spindles seemed to be better than super spindles, even for superintensive culture. The lateral formation needed for slender spindles could be established through applications of Promalin and summer pruning. Based on the positive and negative elements learned from the first trial, a second trial of superintensive sweet cherry culture was set up under a plastic rain cover. In this new trial, economic characteristics of superintensive culture will be calculated. | |
