Weed community responses to agricultural management system sin transplanted cabbage (Brassica oleracea var. capitata)

This study evaluated the effect of different weed management options for transplanted cabbage in North-eastern Croatia. Residual weed communities were assessed at the end of growing season after the effect of different weed managements: (i) chemical ; ii) mechanical ; iii) mulch and iv) control treatments ; had become evident. The dominant species were Cynodon dactylon and Setaria glauca, while Convolvulus arvensis, Galinsoga parviflora and Cirsium arvense were also abundant in 2009, and Digitaria sanquinalis and Echinochloa crus- galli in 2010. Although reduction of species richness was observed with mechanical cultivation, no clear tendency towards the increase or decrease of any weed functional group in relation to management practice was found. Overall, canonical correspondence analysis indicated that the major variations in species composition were associated with mechanical cultivation (axis 1), followed by floristic differences in control vs. each treatment plots (axis 2).
