Improvement of vineyard management of Vitis vinifera L. cv. Grk in the Lumbarda vineyard region (Croatia)

The vinegrowing region of Lumbarda, located in the south-eastern part of the Island of Korcula (Croatia), with its specific deep sandy soils (paleodunes) associated with Mediterranean climate provides optimum conditions for cultivating the autochthonous vine variety - Vitis vinifera L. cv. Grk. Unfortunately, growers have lately faced the problem of declining yield and quality of grapes due to inadequate vineyard management (particularly unsustainable management of soil organic matter) and the occurrence of viral diseases. To revitalize and maintain the vineyards in the Lumbarda region, a detailed study is being carried out, involving intensive soil survey, analysis of grapevine nutrient status, positive clonal selection and establishment of new vineyards with virus-free plant material. Preliminary soil survey results provided an insight into the extent of variability in major physical and chemical soil characteristics. Based on these results, eight markedly different vineyards were selected for detailed analysis of grapevine nutrients (B, Ca, Cu, Fe, K, Mg, Mn, P, Zn) at the key development stages in order to detect potential imbalances that may hamper the vine growth and affect its production. Leaf blades and petioles were sampled at mid-flowering and mid-veraison stages during the 2007/08 growing season from each of the selected vineyards. The highest variability in nutrient content between the study sites was recorded for Cu while considerable variability was also determined for B, Mn, Mg and P. Differences in fertilization practices are the most common reasons for this variability. The results point to boron deficiency in some of the vineyards, and suggest potentially toxic levels of Cu in others.
