Other claims from this paper (17)
- Observation Unrestricted weed growth caused up to 84% loss in lentil yield at Rubatab.
- Observation The critical period of weed control at Rubatab was between 2 and 4 weeks after sowing.
- Observation The critical period of weed control at Dongola, a cooler location with a longer growing season, was between 4 and 6 weeks after sowing.
- Observation The herbicide mixtures imazethapyr, terbutryn and prometryn, each with pendimethalin, were tolerated by lentil.
- Observation The herbicide mixtures controlled weeds effectively at Wad Hamid.
- Intervention effect The herbicide mixtures significantly increased lentil yields at Wad Hamid.
- Association Efficacy of the herbicides in controlling weeds at Rubatab was low, because Tephrosia apollinea and Melilotus indica tolerated them.
- Association Efficacy of the herbicides was reduced in heavier soils.
- Observation A tank mixture of oxyfluorfen with terbutryn or prometryn gave good weed control at Wad Hamid.
- Intervention effect The tank mixture of oxyfluorfen with terbutryn or prometryn increased lentil yield at Wad Hamid.
- Observation A higher dose (1.5 kg a.i. ha(-1)) of terbutryn and prometryn caused phytotoxicity in lentil.
- Intervention effect Irrigation before seed-bed preparation reduced grass weeds by 58%.
- Intervention effect Irrigation before seed-bed preparation reduced broad-leaved weeds by 40%.
- Intervention effect Irrigation before seed-bed preparation gave a 30% increase in lentil grain yield over no irrigation.
- Observation Pre-emergence oxyfluorfen with one supplementary hand-weeding gave excellent weed control in lentil.
- Intervention effect Pre-emergence oxyfluorfen with one supplementary hand-weeding increased lentil yield by 57% over the weedy control.
- Recommendation Presowing irrigation, pre-emergence herbicide and one hand-weeding form an effective integrated package for controlling weeds in northern Sudan.
