Two, acre blocks, one treated and one control. Rate 2 quarts of Spray-N-Grow/50 gallons of water. First application, July 1, just before bloom. Second application – 30 days later.
Brix: 20.0 (+3.5)
pH Direct: 3.2 (+0.2)
Titratable Acidity: 1.19 (-0.14)
pH Direct: 3.0
Titratable Acidity: 1.33
First trial interested primarily in quality of juice and the resulting wine produced. Production of finished wine will be monitored from treatment and control. Grapes from treated block set heavier and were ripe approximately a week earlier. There were some vine misses in the field which would not give an accurate per acre yield.
Photos show yield differences on average plants. Quality of treated fruit excellent. Grower enthusiastic with the results and will continue trials next year. Trials will also be conducted on varieties that have a past history of poor set. A larger acreage with another grower who harvests by machine will also be treated and should furnish more accurate data on over all yields.
