Field Study

Vitazyme on Cotton – 2007, College Station, Texas

This replicated cotton study at Texas A&M university revealed that Vitazyme significantly impacted all growth and yield parameters in a positive direction. Over all nitrogen levels, these parameters produced the following significant effects at P=0.05:
Height at early bloom

........................................................................... 6% Nodes per plant at early bloom

............................................................ 3% Height at 28 days after early bloom

.................................................... 5% Nodes per plant at 28 days after early bloom

..................................... 6% Nodes above white flower at 28 days after early bloom

.................... 5% Lint yield

................................................................................................. 6%

The improved growth parameters translated into a 6% lint yield increase. Especially noteworthy is the fact that, at 60 lb/acre of nitrogen, Vitazyme increased the lint yield by an amazing 20% above the untreated control, this yield about equaling the 120 lb/acre nitrogen rate yield and exceeding the 120 lb/acre nitrogen rate alone by 89.3 lb/acre. This effect demonstrates the ability of Vitazyme to help the plant better utilize nitrogen, and allow the grower to reduce nitrogen applications without sacrificing yield ... in this case by reduc- ing such applications by 50%. Yield increase with Vitazyme was 9% at the 120 lb/acre nitrogen rate, and 7% at the 90 lb/acre rate. Nodes above white flower at 28 days after early bloom was an accurate predictor of final lint yield.

Fiber length was significantly enhanced by both Vitazyme (2%) and nitrogen (up to 4%), while fiber strength was improved by up to 9% by nitrogen. Vitazyme with the 120 lb/acre nitrogen rate, however, produced the single greatest fiber strength value of any treatment.
