Control of Barley Weeds and its Reflection on the Growth Parameters

A field experiment was carried out to evaluate the efficiency of specific weed herbicides in controlling the weeds grown with cultivars of barley and their effect on some growth traits. The study was implemented using Randomized Complete Block Design (RCBD) with split plots arrangement by three replicates. The results showed the superiority of a herbicides combination (U 46 - Combifluid 1 L.ha -1 ) + (Axial 1.5 L.ha -1 ) (h 1 ) by giving the best results as it reduced the weed dry weight to 0.00 g.m -2 with a 100% inhibition ratio. Furthermore, it gave the best results within growth parameters as it increased the flag leaf area and the growth rate of the crop, which reached 40.94 cm -2 and 59.14 g.m -2 day -1 , respectively. In the same role, the results also showed the superiority of the cultivar IPA 265 (V 3 ) by giving the best results for plant height, flag leaf area, and crop growth rate, which were 92.62 cm, 45.44 cm -2, and 61.02 g.m -2 day -1 , respectively. The interaction was also significant, as the treatment with H 1 herbicide and the treatment of hand weeding behaved similarly for almost all traits and with all cultivars by giving the best results for the interaction.
