Other claims from this paper (9)
- Association The longer onion was kept weed free or the earlier weeds were removed after transplanting, the higher the onion growth and bulb yield.
- Association The highest yield was obtained from the weed-free plots for the entire growing season.
- Association No yield was obtained from weed-infested onion for the whole growing season in the Jordan Valley.
- Association Bulb yield was reduced by 86% in weed-infested onion at the University Campus experiment.
- Association Bulb yield was not significantly changed by 14 to 49 days of weed-infested crop at both locations.
- Association No weed-free period gave yield similar to the weed-free control in the Jordan Valley.
- Intervention effect Weed-clean onion for three weeks after transplanting significantly increased bulb yield over the weed-infested control at the University Campus location.
- Association Weed growth and development was much higher than that of onion plants, especially under irrigation.
- Observation The critical period of weed competition in onion was 50 days after transplanting at both locations.
