Cold weather Vitazyme in this New York on-farm field study performed better than the stan- dard Vitazyme by raising corn yield by 6% (8.6 bu/acre) and reducing grain moisture by 1.3 percentage points more than the standard formulation. Such improvement led to $36.21 more income per acre for the new cold formulation. This result shows considerable promise for the use of this product during cold spring conditions.
