Increase Yields, Suppress Disease with Grafted Tomatoes

Grafted tomato comparison
Grafting vigorous, disease-resistant tomato rootstocks to desirable fruiting varieties has become a cost-effective method for growers to overcome many disease and production related issues.

Grafting tomatoes can improve production and overall crop health and vigor; reduce or eliminate the need for pesticide use; lengthen harvest duration; and significantly increase net income.

Results of Our Grafted Tomatoes Trial

In 2010, we used the hoophouse tomato trial at Johnny’s research farm in Albion, Maine to quantify the yield boost resulting from using a vigorous tomato rootstock grafted to a desirable fruiting variety. Sets of three plants of each variety were grown, with three grafted to #2700 Maxifort and three grown on their own roots. Yields averaged over 40% higher for the grafted plants. Results are tabulated below.
