This Russian corn trial from the Krasnodar Region revealed that Vitazyme improved ear size (10% more corn per ear), and increased the yield significantly (P = 0.05) over the control, also by 10% (4.8 c/ha). This increase was a result of using only two 1 liter/ha applications, at the 3 to 4-leaf stage. Even with the yield increase the protein content of the grain was not diminished, but was slightly improved. These results show the great utility of using Vitazyme as a yield and profit enhancer for corn in Russia.
