Grape Field Trials Summary

The use of Spray-N-Grow Micronutrients on wine, table and juice grapes has resulted in:

-Increased yield
-Increased sugar content
-Earlier harvest
-Better fruit quality
-Healthier, more vigorous vines
-More drought resistant plants

A two year study using Spray-N-Grow Micronutrients on wine grapes in New Jersey was conducted by Dr. A.E. Nightingale, professor emeritus, Texas A&M University. The results of this trial were:

Significant yield increase
Increased brix
Better juice chemistry

Dr. Nightingale also supervised a trial in Washington, where Concord grapes were treated with Spray-N-Grow. The Spray-N-Grow increased yields, increased sugar content, and induced earlier fruit maturity.

Chenin Blanc, Cabernet Sauvignon and LeNoir wine grapes were also part of an experiment by Dr. Nightingale. The owner of the Texas vineyard where this trial occurred would not have been impressed with a yield increase if the chemistry of the fruit had been adversely affected. As it turned out, he got impressive yield increases (16, 62 and 68% respectively) and at the same time was able to keep the fruit qualities necessary for making good wine.

Reports from wine, table, juice and raisin grape growers that are not involved in these trials confirm these results of increased yield, increased sugar, earlier ripening, increased size and overall improved quality. Many grape growers throughout the USA and many countries around the world are currently using Spray-N-Grow Micronutrients on their grape crops.
