A Ukrainian replicated pea trial, comparing Vitazyme biostimulant with an untreated control, at four fertility levels, revealed that Vitazyme increased pea yield at all levels, by from 21 to 25%. Crude protein was likewise enhanced by this product, by 1.0 to 1.3 percentage points. Thus, both yield and quality were improved by Vitazyme with all four fertility regimes, proving the great efficacy of this product in the context of a comprehensive soil and crop management system.
