In 2009 and 2010 a split, split, split plot experiment with training system, VSP or Smart-Dyson Ballerina (main plot), N, 0 or 33.6 kg/ha (split), crop level, 14.0, 18.7, or 23.4 clusters/m/canopy (split), clone, Cabernet Franc 1,4, 8 and 214 treatments with five replications were established in Union County, Illinois on mature vines. The Smart-Dyson Ballerina training system produced a Ravaz index that was 89% and 28% bigger compared to the VSP respectively in 2009 and 2010. In 2009, the Smart-Dyson Ballerina produced a 80% bigger yield than VSP and in 2010 yield was also larger, but influenced by both training system and crop level. Maintaining a balanced vineyard can increase profit for the grower by up to $6,356.87/ha.
