This Ukraine study on vetch revealed that the harvested yield was improved considerably with Vitazyme applied to the seeds (+19%), but especially when an additional 1.0 liter/ha was applied to the leaves and soil (+28%). Income also increased substantially with both Vitazyme treatments. Vitazyme is shown to be an excellent material to add to the usual cultural program for more effective use of soil and fertilizer nutrients, to improve yield and profitability.
