| ABSTRACT: Field experiments were carried out on sugarcane Saccharum officinarum L. in the fields of the general company for industrial crops, Dhuluiya (within the central region of Iraq) during the years 2001-2002 and 2002-2003 to evaluate the efficacy of herbicides added at the beginning of tillers stage for weed control , improvement of sugar yield and quality of sugarcane (cultivar: Co196). Randomized complete block design was used with four replications . The treatments included four herbicides, viz. fluazifop-butyl, Chevalier (mesosulfuron + iodosulfuron), glyphosate and paraquat, and weedy check (control) . The results indicated that the use of all herbicides achieved increase in weed control, improvement of sugar yield and quality of sugarcane. So that the use of paraquate has led to highest increase in percentage of weed control (89.12 and 85.90 %) with achieve highest in percentage of inhibition in dry weight of weeds (91.22 and 86.40 %) for both years respectively , this results caused raise the sucrose percentage (14.89 and 14.58 %), purity (88.01 and 87.25 %) and improvement sugar yield (7.94 and 7.60 tonns/ ha) with an increase 83 % and 66 % for both years respectively . Keywords : Sugarcane, Herbicides, Quality, Sugar yield, Weed. | ||
