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.
Highlights
Both productivity and quality of grapevine are the results of climate-soil-plant interactions, and together with vi-How to cite this paper: Quezada, C., et al (2014) Influence of Soil Physical Properties on Grapevine Yield and Maturity Components in an Ultic Palexeralf Soils, Central-Southern, Chile
Soil physical properties essentially regulate the potential volume of soil that can be explored by roots, plant roots growth and distribution, soil water availability, root respiration and exchange of soil oxygen [5], with direct effects on irrigation and vineyard management and berry quality [4] [6]
The greater yield was obtained in textural class sandy clay and clayey loam
Summary
Both productivity and quality of grapevine are the results of climate-soil-plant interactions, and together with vi-How to cite this paper: Quezada, C., et al (2014) Influence of Soil Physical Properties on Grapevine Yield and Maturity Components in an Ultic Palexeralf Soils, Central-Southern, Chile. Nagarajah [7] determined that rooting depth was higher in coarse soil; roots were well spread throughout the soil profile, as they are concentrated in the top 40 to 60 cm in both moderately coarse and fine soil. Soil properties such as the presence of soil profiles impermeable to root penetration, stoniness and presence of gravel lenses have a greater influence on depth distributions than that of genotype, even in deep fertile soils [6] [8]
