| Abstract | ||
| This study was carried out to weed control associated the maize in the Rashidiya area in one of the northern of the city of Mosul, Nineveh Governorate in agricultural season in the 2021 AD in the northern region of Iraq to evaluate the efficiency of herbicide that was recently introduced into Iraq. The study included two factors: the first factor was the use of the herbicide (Adengo) in three concentrations (200, 300, 400 ml. h) and a weeds-free treatment (hoeing throughout the growing season) and a control treatment. two cultivars of maize were used : As for the second factor the first local ( governmental variety) ، the second is an imported hybrid (Dk 5060) . As the seasons (the date of sowing) were entered as a third factor in the aggregate analysis. The statistical analysis was conducted by designing randomized complete sectors according to the global experiment system. Duncan’s multi-range test was used using the computer according to the (SAS) program. The results were summarized as follows: Adengo herbicide concentrated (400 ml. H) showed significant superiority in eliminating thin and broad-leaved weeds and reducing them when flowering،The efficiency of Adengo herbicide was equal at a concentration of (300, 400 ml. ha) as it did not differ significantly despite the superiority of the concentration of (400 ml. ha) in the autumn season،The superiority of the herbicide at a concentration of (400 ml. H) in most of the growth characteristics of the crop،The use of the herbicide at a higher concentration than recommended led to an increase in weeds killing, as its efficiency in reducing the dry mass of the weed was (71%) and its efficiency in reducing the weed density was (75%) compared to the control treatment، It was observed that the efficiency of the weed-free treatment and the Adengo herbicide at a concentration of (400, 300) ml was equal in many characteristics the number of rows in the ear. and the percentage of protei | ||
