Intensive agricultural practices of past decades— such as mechanical cultivation on steep vineyard slopes—can endanger soil fertility. In addition, climate change scenarios predict heavier rainstorms, which can further accelerate soil degradation. Therefore, the use of cover crops in the inter-row has a special importance, particularly on steep slopes and in organic agriculture. A species-rich cover crop mixture helps not only in preventing erosion and providing easier cultivation, but has also positive effects on soil structure, soil fertility and ecosystemfunctions (Bauer et al. 2004; Hofmann et al. 2008). We began to develop and test several species-rich cover crop mixtures in spring of 2012 in Hungarian vine regions. During the experiments, three species-rich cover crop mixtures (Biocont-Ecovin mixture, mixture of legumes, mixture of grasses and herbs) were compared in vineyards of the Tokaj vine region. Each mixture was sown in three subsequent inter-rows at each site of the experiment. In the control blocks, unsown inter-rows and mechanically cultivated inter-rows were located subsequently next to each other. We studied weed control, yield quantity and must quality in every treatment. We found that the cover of weeds was lower in every treatment compared to the unsown control plots for 2013; thus, cover crops suppressed the weeds of the inter-rows effectively. Most examined indices of grapevines were not significantly affected by the applied cover crops. However, the yield loss results show that under Hungarian climate, the soil coverage in every second inter-row is more recommendable than subsequent seeding, where total erosion control is not required. The interest of the vine growers shows the importance of the topic; thus, we involved other wine regions of Hungary in our further experiments.
