Evaluation of Pre and Post-Emergence Herbicides: It’s Effect on Weed Dynamics, Yield, and Yield Components of Barley (Hordeum vulgare L.) in Awi Zone, Northwestern Ethiopia

Field experiments were conducted to evaluate different herbicides’ efficacy and their effect on yield and yield component of barley. Results of the experiment revealed that the dry weight of weeds, yield and most yield components of barley were significantly affected by the type of herbicides applied. Thus, the maximum weed dry weight of 206.7 gm ^-2 was recorded from the weedy check followed by plots treated with crop star 93.1gm ^-2 in Guagusa Shikudad. However, the least was obtained from plot treated with two times hand weeding (26.23 gm ^-2 ) in Banja district next to dry weight of weeds from the weed-free check (0.00gm ^-2 ). Besides, the maximum grain yield of 3238.9kg ha ^-1 and 3220kg ha ^-1 , respectively was recorded from weed-free checks and plot received musket power treatment at Banja. The application of Musket power expressed the maximum marginal rate of return (174.61) and net benefit, reflecting effective management of weeds in barley.
