We present data on the nutrient characterization of a Spanish autochthonous grapevine, Bobal,in comparison with the well-known cultivar Tempranillo when vines are grown followingdifferent plant-soil system management methods. Since mineral nutrition is an important factoraffecting grape composition and wine quality, we determined the nutrient status of bothcultivars at four different phenology stages. On the basis of these data, Bobal and Tempranillovineyards were both subjected to four treatments as a result of combining different pruningtechniques (traditional-hand or mechanical-minimal pruning) with the presence/absence ofleguminous species in the lines between vine rows. We evaluated the effects of these cultivationmodifications on soil and plant nutrients (N, P, and K evolution). Our first results suggestveraison as the most suitable time for the nutritional evaluation of grapevine owing to the factthat leaf mineral composition showed higher stability at this phenology stage. Regarding thecombined cultivation methods tested, the data obtained from the use of leguminous species didnot lead to conclusive results. However, minimal pruning vs. hand pruning methods clearlylowered management costs, maintained the nutrient status of soils and grapevines, and thequality of Bobal and Tempranillo berries.
