Plant attributes of the grapevine, such as number of rods and weight of pruned material and number of branches per plant. At the time of skin color change, petioles of recently matured leaves were collected for analysis of the levels of N, P, K, Ca, Mg, Fe, Mn, Zn and B. Moments before harvest, 100 grape berries were collected randomly to determine the total soluble solids, titratable acidity and pH. At harvest, the number of bunches per branch, the number and mass of clusters per plant and the average mass of clusters per plot were determined. Fresh and dry matter yields of the cover crop and weed plants were also determined when coverage reached full bloom. The winter cover crops did not alter the yield and quality of " Cabernet Sauvignon " grapes and showed no differences from each other for the management of spontaneous vegetation by hand weeding or mechanical mowing. Rye and ryegrass are effective alternatives for weed control alternatives. The species of white and red clover present difficulty in initial establishment, producing a small amount of biomass. Comportamento vegetativo, produtivo e qualitativo de videiras 'Cabernet Sauvignon' em fun????o do uso de plantas de cobertura de inverno Para estudar o efeito das plantas de cobertura de inverno sobre o comportamento vegetativo, produtivo e qualitativo de videiras 'Cabernet Sauvignon', foi conduzido um experimento em duas safras vit??colas, com semeadura de diferentes esp??cies de plantas de cobertura de inverno e tratamentos adicionais com capina manual ou ro??ada mec??nica, em um vinhedo experimental localizado na Esta????o Experimental da Epagri em Videira, SC. Foram avaliados atributos vegetativos da videira, tais como n??mero de varas e peso do material podado e o n??mero de ramos por planta. No momento da mudan??a de cor da casca, foram coletados pec??olos de folhas rec??m-maduras para an??lise dos teores de N, P, K, Ca, Mg, Fe, Mn, Zn e B. Momentos antes da colheita, foram coletadas aleatoriamente 100 bagas para determina????o do teor de s??lidos sol??veis totais, acidez titul??vel e pH. Na colheita, foram determinados o n??mero de cachos por ramo, o n??mero e a massa de cachos por planta e a massa m??dia de cachos por parcela. Tamb??m foram determinadas a produ????o de massa verde e seca das plantas de cobertura e das plantas daninhas quando as plantas de cobertura atingiram a flora????o plena.  agreen manure  aproduction systems  asoil management  aVittis sp1 aFELDBERG, N.1 aNAVA, G.1 aVEIGA, M.1 aWILDNER, L.
