Two replicated shoot positioning field trials were conducted from 1987 to 1990; one with Chardonnay, Sauvignon blanc and Cabernet Sauvignon vines at the Oakville Experimental Vineyard and the other with Chenin blanc vines at Davis. Chardonnay. Sauvignon blanc and Cabernet Sauvignon trial: The main conclusions obtained from the Chardonnay, Sauvignon blanc and Cabernet Sauvignon shoot positioning-hedging trial conducted at the Oakville Experimental Vineyard over a period of five years (1987 to 1990) may be summarized as follows. Conclusions are based on five-year averages. 1. Shoot positioning/hedging (SP) of Chardonnay and Sauvignon blanc increased crop yield by 4 to 5%or 0.4 tons/acre compared to no shoot positioning (NSP) and hedging (Tables 1 and 2). Shoot positioning and hedging did not effect the crop yield of Cabernet Sauvignon. 2. SP reduced the amount of direct light and increased the amount of indirect light (diffuse light) in the fruiting zone.
