In this replicated three-year study in Oklahoma of the effect of Vitazyme on the yield and nutritional value of bermudagrass, at three locations, no significant increases in these parameters occurred with Vitazyme at any of the three nitrogen levels. However, Vtiazyme boosted the yield by 8% at the 50 lb/acre N rate, and by 14% at the 100 lb/acre N rate. The product also appeared to improve calcium and potassium levels of the forage at these two nitrogen rates, but the other elements and nutritional parameters were not affected. Vitazyme holds promise as a potential enhancer of bermudagrass yield and quality in dryland range settings in Oklahoma.
