| Abstract | ||
| Two pot experiments were performed in the wire greenhouse of the National Research Centre, Dokki, Giza, Egypt during two successive winter seasons of 2020/2021 and 2021/2022 to study the allelopathic efficiency of Anethum graveolens seed powder (AGSP) in comparison to the herbicidal effect of glyphosate treatment (0.375 ml/l) in controlling the parasitic weed broomrape infected faba bean as well as their effect on growth and yield of the crop. Treatments were applied by incorporating different AGSP concentrations (5, 10, 15, 20, 25, 30, 35 and 40 g/kg soil) into the soil. Broomrape seeds were obtained from the Weed Control Section, Ministry of Agriculture, Giza, Egypt. All pots, except healthy control, were infected with broomrape seeds (0.2 g/pot) at 5 cm depth from the soil surface. All AGSP concentrations used and herbicide treatment decreased all broomrape parameters i.e. number, fresh and dry weight of tubercles/pot at 90 days after sowing (DAS) and at harvest as well as tubercles length at harvest only. The best treatments for controlling broomrape were recorded with 40 and 35 g/kg soil AGSP concentrations compared to the herbicide glyphosate treatment at harvest. AGSP treatments at 35 and 30 g/kg soil concentrations achieved the maximum significant increases, exceeding their corresponding healthy control and glyphosate treatment. Therefore, the allelopathic effect of AGSP due to the presence of allelochemicals, mainly phenolic compounds and flavonoid contents, could play an essential role as a natural selective bioherbicide in controlling parasitic weed broomrape infesting faba bean plant and increasing the plant growth and yield. | ||
