Abstract:
The experiment was carried out with the split plots design, with three replications, at the Scientific Agricultural Research Center in Salamieh (Syria), during the 2017-2018 agricultural season, with the aim of studying the effect of three sowing rates of lentil (250, 300, 350) seed/1 m2, and three rates of Aclonifen herbicide (600, 900, 1200) g a.i/Hectare at post-planting treatment, in addition to hand weeding twice after 60, 90 days of cultivation and weedy control, in controlling wild mustard (Sinapis alba L.) and its reflection on productivity. The results showed that the sowing rate of 300 seed/1 m2 gave the highest control efficiency, and reached 80.02% according to the green weight of mustard, the highest productivity of lentil, and recorded 144.27, 45.56 kg/dunum for hay and seeds respectively, and with significant differences compared to rates 250 and 350 seed/1 m2. The highest rate of 1200 g a.i/Hectare of Aclonifen herbicide was the best control efficacy, and scored 85.3% according to the green weight of mustard. The hand weeding treatment at the sowing rate of 300 seed/1 m2 gave the highest productivity of lentil compared to the rest of the treatments, and recorded 217.67 and 86 kg/dunum of hay and seeds, respectively. Light phytotoxicity of Aclonifen’s rates was noticed on lentil but melted rapidly.
