Abstract: BACKGROUND:There is growing interest in cover crops for orchards and vineyards to help control weeds and thereby reduce the need for tillage or herbicide applications. However, there is concern that cover crops may compete with the vines for mineral nutrition. OBJECTIVE:The aim of this research was to study how two different soil management practices (tillage and cover crop) affected the nutrient content of clusters and leaves of table grape vines. METHODS:In 2015 and 2016, the effect of soil management practices on the concentration of nitrogen, phosphorous, potassium, calcium, magnesium, sodium and sulphur in leaves and clusters of Italia table grape vines (Vitis vinifera L.) in a vineyard located in Puglia (South-eastern Italy) was determined, throughout the growing season. RESULTS:Nutrient concentrations in leaves and clusters varied during phenological stages each growing season, and there were significant differences induced by the two soil management practices. The presence of cover crop increased the content of calcium and sodium in clusters and phosphorous and sulphur in leaves. No deficiencies were noticed in the two years and yields were similar regardless of soil management practices. CONCLUSIONS:This study, carried out in an irrigated table grape vineyard, showed that cover crops could be used as sustainable soil management strategies without significant influence on yield and fruit quality with respect to vines subjected to traditional tillage. Moreover, nutrient concentrations in leaves and clusters was almost similar in the two treatments with only few exceptions.
