The results of two trials initiated in Ventura County in 1960 show that severe training and hedging of young Valencia orange trees significantly decreased production. The data from trial 1 at Saticoy clearly show that production from the large number of trees per acre did not compensate for the fruit lost because of training and hedging. Although fruit loss was less at trial 2 near Somis, where the tree density was lower, it still remained too high for commercial acceptance.

Petty Ranch, Rancho Ventura, Kimball Toppers, Coastal Growers, Ojai Tapo and Mupu Citrus Packing House cooperated in these trials.
