INFLUENCE OF TILLAGE AND WEED MANAGEMENT METHODS ON CHICKPEA (Cicer arietinum L.). II. EFFECT ON WEEDS

Duhok University, Iraq to investigate the effectiveness of different types of tillage and weed management practices on weed control in chickpea field during the growing season of 2009-10. Tillage types included the use of disc plow, mouldboard plow, and cultivator and weed management practices included no weed control, hand hoeing, trifluraline (Treflan), haloxyfop-pmethy (Aloxy) and paraquat (Gramoxone). Results indicated that the plough type had no significant effect on number of weeds ortheir dry weight. Hand hoeing followed by paraquat herbicide were superior in number and dry weight of broad-leaved weeds (8 weeds m-2 and 11 g m-2) and (35.22 weeds m-2 and 53 g m-2), respectively. The interaction of hand hoeing with all types of tillage systems was significant. The interaction of paraquat with disc plow gave the lowest dry weight of broad leaved weeds (35 g m-2). Neither the number of narrow-leaved weeds nor their dry weight had any marked effect on chickpea.
