Both the New Vitazyme and Product B in this cold weather growth response study gave significant increases in plant height, of 35% and 30%, respectively. Vitazyme gave a 12% increase in height over the 70-day period of the test. New Vitazyme and Product B hold much promise in stimulating good seedling growth during cold and wet conditions, typical oftentimes of planting conditions in the U.S. and Canada during many planting seasons.
