Firebaugh, California |
Variety: Heinz 8892 paste tomatoes Planting date: April 16, 1997 Soil type: unknown In-row spacing: unknown Harvest date: September 15, 1997 |
Vitazyme application: Vitazyme at 12 oz/acre was added directly to the seeds at planting with a starter, and again at 5 oz/acre, sprayed over the top of the plants at the end of April. |
Comments:
According to the farmer, "We
were unfortunately unable to separate the yield of the Vitazyme section
of the field from an adjoining 30-row section that had Kwik-Start
(7-21-0), or from any untreated areas of the field. These early
tomatoes were used to mix with other tomatoes that had more rot, to
improve the overall grade. I would estimate the yield improvement
of Vitazyme and Kwik-Start compared to the regular planting as follows: Kwik-Start: 1 to 2 tons/acre ($50 to $100/acre) Besides the improved yield, the Vitazyme treated tomatoes were firmer, had fewer green fruit, and were more uniform in size than the other parts of the field."

Hanford, California |
Variety: 370's (plants) Soil type: sandy loam Irrigation: furrow |
Vitazyme application: 13 oz/acre at planting, 13 oz/acre knifed in with the fertilizer |
Comments: The Vitazyme treated plants displayed superiority to the control plants during the season, with better color and size of the plantings. At harvest the treated area was not kept totally separate from the control area, so accurate yield results were impossible. However, the following observations on the Vitazyme treated tomatoes were made.

Fertilization: according to soil test |

Fredonia, New York |
Variety: unknown Soil type: clay loam |
Vitazyme application: 13 oz/acre in the transplant water, and two more 13 oz/acre applications with cover sprays, beginning at fruit set |
Comments: Comments made by the researcher: "The yield was higher than usual. Overall plant health was superior, and quality was consistent throughout the season. This treated crop, although planted later than some other fields in the area, was the first to ripen. Also, this crop continued to yield late in the season when others had quit, with good quality even late in the season."

Fertilization: balanced fertilizer applications with regular cover sprays, especially with fungicide sprays after fruit set |
