Field Study

Vitazyme on Potatoes – 2005-Havana Province, Cuba

Despite several problems in the conduct of this study including delayed planting times, severe Phytophthora infestations, and inadequate irrigation water, Vitazyme increased tuber yields by up to 26% in this Cuban potato trial. Fertilizer reductions of 10 to 25% would likely have shown benefits in cost savings, but even so the economic benefit of Vitazyme was 402.53 Ps/ha.
