ABSTRACT
The conventional hand weeding practices were compared with weedicides (2,4-D, Ronstar and Tribunil) application to control different weeds and to observe the improvement of onion (Allium cepa) yield by considering some plant`s morphological characters (number, size and weight of bulbs) in transplanted onion. 18 weeds of different families were recorded from the experimental plots. Ameranthus hybridus, Convolvulus arvensis, Cyperus rotundus, Chenopodium album, Echinochloa spp. and Sophora alopecuroides were the most damaging. All the treatments (cultural and chemical control methods) had positive significant effect on the weed control and onion yield. Three years field trials revealed that cultural control (four hand weeding) is the best for weeds control in transplanted onion, because it provided maximum weeds control in the tested crop
