According to the researchers, “Although not significant, Vitazyme + Alpine EXP 6-24-6 (Treatment 5) on plug transplants had the greatest effect on yield. Compared to the untreated check, this treatment increased yield by 8.5 tons/acre (37.4%) and improved head quality. RiseR and Hydra-Hume also increased yield by 5.6% and 3.8%, respectively, on bareroots, and by 4.0% and 2.6%, respectively, on plugs, although not significantly. Note, Hydra-Hume did have a higher percentage of poor qual- ity heads at harvest compared to the untreated check.”
