Trinidad, West Indies (Caribbean Chemical International) |
Variety: Salvation Planting date: Spring, 1999 Harvest date: unknown |
Vitazyme application: Two rates of Vitazyme were used, at 15 and 30 ml/gallon (about 0.5 and 1 oz/gal, or 0.5 and 1%), with about 4 gallons of each sprayed on 500 to 600 plants at 11 days after transplanting. Enough product was applied to run off the leaves into the root zone soil. A second application was made about 30 days after transplanting. |
Comments: Although no yield checks were made, growth observations were made during the growing season. No differences in the treatments were noted until about 45 days after planting. After that time the Vitazyme treated plants at 30 ml/gal revealed the following advantages over the untreated control and the 15 ml/gal rate:
The 15 ml/gal spray rate did not improve cabbage growth above the control treatment.  |

Trinidad, West Indies (Caribbean Chemical International) |
Variety: Tropicana Planting date: April 4, 1999 Harvest date: June 5, 1999 (62 days after planting) |
Vitazyme application: The three rates of Vitazyme were prepared at 15, 20, and 30 ml/gal (about 0.5, 0.7, and 1.0 oz/gal, or 0.5, 0.75, and 1.0%) and sprayed on the plants and soil at transplanting (April 4, 1999), and again 2.5 weeks later (April 23, 1999). The spray was directed over the root zone. |
Head Weight, 62 days after transplanting:
Control: 1.8 lb Vitazyme, 20 lm/gal: 2.5 lb (+39%) Vitazyme, 30 ml/gal: 3.5 lb (+94%)
Plant characteristics, 28 days after transplanting: At 30 ml/gal Vitazyme, leaves were darker and larger, vigor was higher, stems were thicker, roots had larger major roots and many more fibrous roots, 50% of the plants forming heads vs. none, excellent uniformity, and little pepper spot infection compared to the control.
