They are highly suffering due to weed infestation especially competing for water and nutrient. However, before estimating yield losses due to weeds and devising weed control strategies, identification and quantification of weeds are very important. The weed survey was conducted in East showa, Arsi, Bale, North wollo and North Gondar zones during 2016 and 2018 in main cropping seasons to identify most common and prevalent weeds associated with seeds spice (coriander, fenugreek and black cumin).
