Effect of tillage as weed control method on maize (Zea mays L.) under Dongola area conditions- Northern State (Sudan)

摘要

A field experiment was conducted during two summer seasons; 2005/06 and 2006/07, at Dongola area- Northern State (Sudan). The objective was to investigate the effect of some tillage systems on weeds control on maize (Zea mays L.). The results indicate that tillage had no significant effect (P ≤ 0.05) on the number of broadleaf weeds and the total number of weeds, but they significantly affect (P ≤ 0.01) the number of grasses in both seasons. The tilled treatments reduced the total number of weeds in both seasons compared with no-tilled.
