Vitazyme on Potatoes – 2009-FortGarland,Colorado

This potato trial on Blazer Russets in southern Colorado showed that Vitazyme, while not improving yield, significantly increased the tuber size. The >9 oz tubers were increased by 23% over the untreated control, while the medium-sized tubers (6 to 9 oz) were significantly increased by 12% more than the control. Tuber numbers were not evaluated, but it is presumed that a Vitazyme application at tuber ini- tiation would have increased tuber numbers — an important issue for seed growers — which would make this product an especially valuable product for potato seed production. The drought period, induced when the irrigation well would not operate, also likely affected the results adversely.
