Abstract:
This study was conducted to evaluate the bioherbicidal properties of orange peels against canary grass and cheeseweed mallow and the response of common bean plants. Two successive pot experiments were conducted with twelve treatments. The first four treatments were applied by incorporating of orange peels powder with the soil surface at successive rates (10, 20, 30 and 40 g/pot) one week pre-sowing of common bean. In the other corresponding four treatments, the orange peels powder was incorporated with the soil surface at the same rates but directly at the same time with sowing of common bean seeds. Additionally, four untreated control treatments were applied for comparison. The recorded results revealed the inhibitory allelopathic effects of orange peels powder on both weeds with direct relationship between the orange peels rate and it's inhibitory effects. However, the pre-sowing treatments were more effective than the others which applied at the time of sowing. Orange peels at 40g/pot at one week pre-sowing gave the highest inhibitory effect on both weeds. This superior treatment subsequently recorded the highest growth parameters and yield traits of common bean. Estimated phenolic compounds, flavonoids and essential oils in orange peels may be responsible for this inhibitory effect.
