In this hard red winter wheat study in western Texas, Vitazyme applied twice through the irrigation water during a hot, dry summer provided a superb yield increase of 29%. This increase resulted in an income increase of $163.20/acre, showing the great ability of Vitazyme to assist wheat growers in semi-arid regions. Presumably the product is enabling the crop to make a better use of fertilizer nitrogen, as demonstrat- ed in several other studies.
