Evaluating the allelopathic potentiality of seed powder of two Brassicaceae plants in controlling Orobanche ramosa parasitizing Lycopersicon esculentum Mill. plants

Abstract

The results indicated that no O. ramosa infestation on Lycopersicon esculentum appeared with all Essp and Sasp concentrations except with the lowest concentration (5 g/kg soil) that reduced O. ramosa tubercles dry weight at 100 days from transplanting (DFT) to about 48.4 and 42.0%, respectively, as compared to the infected control. Lycopersicon esculentum growth as well as its yield and yield components were significantly increased with Basamid treatment at 0.2 g/pot and all Essp and Sasp concentrations (5–45 g/kg soil) except some parameters with the lowest concentration (5 g/kg soil) of both materials used when compared with their corresponding infected control. The highest yield, which exceeds the yield of the healthy control, was obtained by using both Essp and Sasp at concentrations 45 followed by 30 g/kg.
