ABSTRACT: The effects of soil
physical properties on yield components, grape quality and grapevine yield cv.
Cabernet Sauvignon in Ultic Palexeralf soils located in Central Southern Chile
were assessed. The experimental design was completely randomized with three
treatments of soil texture: clayey, sandy clay and clayey loam. The higher
yield was obtained in the sandy clay and clayey loam soils. The increase of
bulk density, penetration resistance and clay content decreased the number of
clusters per vine, number of berries per cluster and grapevine yield. Soil
texture had not effects on the yield of shoots, berry diameter and total
acidity. However, soluble solids were higher in the clayey soil. Shoot
orientation only had positive effects on the cluster weight, number of berries
per cluster, and grapevine yield, being higher in the upward shoots. This
research remarked the importance of soil physical properties on the selection
of sites with viticultural aptitude.
