Estado nutricional, vigor e produção em videiras cultivadas com plantas de cobertura

摘要: Perennial or annual species of cover crops can be grown in vineyards to protect the soil surface and reduce availability water nutrients vine. The study aimed evaluate nutritional status, vigour yield grapevines intercropped with some under two different managements. A field experiment was conducted for years, 2009 through 2011, a vineyard cv Cabernet Sauvignon Haplumbrept soil. following treatments were evaluated: control, where weeds controlled by chemical drying grapevine row mowing inter row; perennial species, tall fescue (Festuca arundinacea); sequences ryegrass-moha (Lolium multiflorum-Setaria italica) oat-buckwheat (Avena sativa-Fagopyrum esculentum); types crop residues management, without its transfer row. leaves sampled at flowering berries softening stages analysis N, P, K, Ca Mg contents. It determined branches internodes lengths, pruned mass, grape bunches length, width per plant weight 100 it also calculated Ravaz index grapevines. Grapevines succession showed higher total N content flowering, yield. residue from row, did not affect yield, but decreased flowering. as an effective alternative vigor grapevine.
