Allium cepa (Onions) is one of the major vegetables that is consumed all over the world after tomatoes due to is active compounds but weeds infestation during growth phase are the major challenge faced by the farmers which result in a very poor growth and yield of this spice. In this study, the conventional hand weeding practices were compared with weedicide pendimethalin to control different weeds and the morphological characters such as; number, size, height, neck area and fresh weight of the onions bulbs planted at Department of Plant Science and Biotechnology, Botanical Garden, KSUSTA. Twelve (12) weeds of different family were found and identified from the experimental field namely; Urena lobata, Eragrostis tremula, Amaranthus viridis, Senna occidentalis, Cenchruse chintus, Mitracarpus scaber, Commelina lanata, Zornia latifolia, Cassia tora, Sida cordifolia, Cleome viscosa and Euphorbia thyamifolia. In all, the treatments used cultural, chemical and integrated methods had shown a positive significant effect on weed control and yield of onion. This study revealed that cultural control (hand weeding) is the best method of weed, control as it provides maximum weed control in the tested vegetable as well as higher yield
