Vitazyme on Coffee – 2011, Cuba
In this extensive multi-year trial with Vitazyme on coffee in Cuba, using 5% seed and/or rooted plant soakings for 30 minutes, with or without monthly 1% Vitazyme sprays, the treated plants responded exceedingly well to Vitazyme in terms of leaf area, top growth, root growth, nutrient uptake, and improved fertilizer efficiency. The best treatment was 5% before planting + 5% before transplanting + 1% monthly applications. In the plantation, Vitazyme did not increase yield harvested coffee due to a failure of the researchers to add any fertilizer along with Vitazyme to the treated areas. Nevertheless, an economic analysis showed that the Vitazyme treatments nearly always produced the greatest net profit.
