    <description descriptionType="Abstract">&lt;p&gt;Weed is among the various biotic factors constraining wheat productivity in Ethiopia in general and Central Mid-rift valley of Ethiopia in particular. To combat the problem various weed control option identified under different agroecologies for different wheat varieties. Although wheat production is commonly practiced under highland and midland parts of the country, currently it is advancing to lowland parts of the country as a result of the adoption of lowland wheat varieties. This invited identification of appropriate wheat variety and effective and economical weed control method. The study was conducted at Adami Tulu Jido Kombolcha (ATJK) district at two sites (Adami tulu research center) and (Galo Heraphe farmers field) during the crop growing season of 2022 to study the response of different wheat varieties under different weed control methods. A randomized complete block design of three replications and twelve treatments comprised from three wheat varieties(Balcha, Daka, and Wane)and four weed control method (two times hand weeding (30 DAE and 45 DAE), Pallas 45% OD 0.5 L/ha Herbicides (30 DAE), Pallas 45% OD (30 DAE) plus one time hand weeding (45 DAE), and weedy check (zero weeding)). Study result showed that Nikandiraphysaladis and Daturastramonium were found dominant broad leaf weeds at Adami Tulu site, while Setaria pumila (33%) and Avenafatua (18%) were among the grass weed species abundant at the Galo Heraphe location. The weed control methods were significantly influenced wheat yield between the study sites. The least grain yield was recorded from the plots treated with unweeded check (136.12 kg/ha) and (1232.23kg/ha) whereas the highest yield was recorded from plots treated with two times hand weeding (2514.43) and (2733.44kg/ha) followed by Pallas plus one time hand weeding (2370.99kg/ha) and (2442.9kg/ha) without significant difference at Adami Tulu and Galo Heraphe site respectively. Application of two times hand weeding and Pallas plus one time hand weeding showed grain yield advantage 94% and 49% over unweeded control (zero weeding) at Adami Tulu and Galo Heraphe sites, respectively. Maximum mean grain yield of 2073.14 kg was recorded for the Balcha wheat variety followed by the Daka wheat variety (1899.62 kg). However, there was no discernible difference between the two. Finally, Pallas with one-time hand weeding was found quite effective in controlling major broadleaf and grass weed species observed in wheat fields and it was found economically feasible among the weed control methods considered. Among the wheat varieties Balcha and Daka were found high yielders in the study area and recommendable under the study area and similar agro ecologies&lt;br&gt;
