To eliminate herbicide use in no-tillage tomato production, an experiment was carried out to evaluate the best combination of winter cover crops for weed control and tomato production at the Ituporanga Experimental Station in Santa Catarina, Brazil. Oat ( Avena strigosa [ Avena nuda]), vetch ( Vicia villosa) and fodder radish ( Raphanus sativus) were grown in monoculture and in mixes. The tomato cv. Marcia-EPAGRI was stake-trained and grown under fertigation. The highest values in above-ground dry biomass were obtained by oat+vetch and oat monoculture, followed by vetch+radish, oat+radish, and oat+vetch+radish. Treatments with oats had the best performances in controlling resident vegetation, while vetch was associated with the worst performances. There were no significant differences between the treatments for total yield and marketable fruit production.
