CHAPTER 2 REGIONAL TRIAL SITES

These results are applicable to vineyards cultivated on sandy loam soils in other regions. The results from the Stellenbosch sites can also be applied to vineyards in the Coastal and Overberg Regions. Results are relevant to table-grape production in Paarl, Piketberg, and adjacent areas, and to wine-grape production in the Overberg and adjacent regions.
