Merkt, Nikolaus 2019-01-28 Graeff–Hönninger, Simone Merkt, Nikolaus Agroforestry systems (AF) consisting of grapevines and trees, may lead to resource competition for water and nutrients. This study aimed to evaluate the impact of a combined cultivation on water relations, nitrogen nutrition and the resulting wine quality. <sup>15</sup>N-labeled inorganic nitrogen (N) sources were used to quantify net N uptake capacity. N content and δ<sup>15</sup>N natural abundance were analysed as integrating parameters of N nutrition. Leaf water potential (ψ<sub>leaf</sub>) was determined to evaluate the water status of grapevines. Wine quality was evaluated by chemical and sensory analyses. In result, AF system reduced leaf water potential and increased net N uptake capacity in grapevines. However, chemical composition and sensory quality of the wine were not significantly affected in the present system consisting of Riesling, Sauvignon Blanc, oak and poplar. Nitrogen availability of grapevines was favourable and water relations were improved, whereas wine quality was similar when grown with trees or without. Trees were able to reduce water and nitrogen losses without negative effects on wine quality. This work provides information on benefits and limits for intercropping of trees and grapevines in terms of performance of grapevines and wine quality compared to traditional vineyard systems.
