Abstract

The experiment was carried out with the split plots design, with three replications, at the Agricultural Scientific Research Center in Salamieh (Syria), during the growing season 2018/2019, with the aim of studying the effect of three sowing rates of lentil CV. Idlib 3 (250, 300, 350) seed/1 m2, and three rates from herbicides mixture (Haloxyfop-ethoxyethyl ester + Aclonifen) (26 + 600, 52 + 900, 78 + 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 barley (Hordeum vulgare L.) and its reflection on the productive and qualitative lentil crop characteristics.The results showed that the sowing rate of 300 seed/1 m2 gave the highest control efficiency, and reached 75.23% according to the green weight of weeds, the highest values for the height of lentil plants and the number of nitrogen nodes, and the highest productivity of lentil from hay and seeds, and recorded 13.13 cm, 10.22 node, 323.2 kg/dunum , 175.13 kg/dunum, respectively, and with significant differences compared to rates 250 and 350 seed/1 m2. The hand weeding treatment at the sowing rate of 300 seed/1 m2 gave the best results compared to the rest of the treatments, where it recorded the height of 32.67 cm for lentil plants, 10.89 nitrogen nodes, 33.49% protein content, and yielded 495, 280 kg/dunum of hay and seeds, and then came after treatment at the highest rate of the mixture of herbicides used at the second seed rate as well. The use of the highest rate of the herbicides mixture caused light phytotoxicity to the lentil plants at the beginning, but melted rapidly.
