Abstract
Three different trials, at three different localities, each with different growing conditions, were conducted with nine differentwine grape varieties. Four different pruning methods, hand, mechanical, minimal and no pruning were tested. Growthresponses, grape composition and morphology, wine quality as well as labour inputs were evaluated. Huge labour savings wereobtained with the alternative pruning methods compared to hand pruning. A reduction in vigour and increase in yield wereevident in each variety. Wine quality was not decreased and in some cases even a quality increase was evident. Varieties differin their adaptability to alternative pruning methods with Cabernet Sauvignon, Pinotage and Chardonnay performing well andSauvignon blanc and Merlot poorly. Chenin blanc, Shiraz, Colombar and Ruby Cabernet showed acceptable performance.Alternative pruning methods proved to be viable, especially for the production of medium and low priced wines.
