This replicated study of broccoli seedlings shows that Vitazyme, applied at very low concen- trations (only 5 ml of a 0.1% solution per plant) at seeding, produced substantial and highly significant plant growth responses. Plant height was increased by 27%, and leaf area by 49%, with this single Vitazyme appli- cation, showing that the product will produce larger and stronger broccoli transplants than untreated controls over the same time period.
