This greenhouse study revealed that Vitazyme alone significantly increased the growth of corn above the control, improving dry tissue weight at 46 days after planting by 18%. All of the other treatments were statistically equal to the control except Asset, although this treatment was unusually low in height and dry weight for several of the replicates due to soil structure problems (i.e., compaction) in the pots. Thus, soil porosity was low and interfered with root growth.
