Dynamics of <i>Cynodon dactylon</i> and weed community composition in different cover crops in a vineyard

The implementation of cover crops in vineyards is an environment-friendly soil management technique that has several advantages, including weed suppression. effectiveness the depends on characteristics both community and crop species. objectives this study were to evaluate dynamics Cynodon dactylon patches rest composition under five different (four grasses one dicotyledonous species) a commercial vineyard Spain: (1) perennial Festuca arundinacea annual species (2) Hordeum vulgare, (3) Vulpia ciliata, (4) mixture Bromus (5) Medicago rugosa. sown November every year after tillage (from 2015 2018) shredded June, while F. was June year. Results showed affected C. coverage frequency across field. After three seasons, H. vulgare best which controlled dactylon, resulting lowest 4.6% 3.0% respectively. Although expansion restrained by crops, prior sowing spreads rhizomes stolons free areas Canonical Correspondence Analysis (CCA) varied depending species, revealing importance its assemblage.
