Abstract
Hosh, M., S. Tabbache, D. Haddad and H. Habak. 2022. The Effect of Dried Powdered Leaves of Radish (Rhaphanus sativus L.) in Decreasing the Parasitism of Orobanche ramosa L. on Tomato (Solanum lycopersicum L.) Grown in Greenhouses. Arab Journal of Plant Protection, 40(3): 280-285. https://doi.org/10.22268/AJPP-40.3.280285 The allelopathic effect of dried leaves powder mixed with soil at concentrations of 1, 2, 4% of Raphanus sativus on both parasitic weed Orobanche ramosa L. germination and growth of tomato Solanum lycopersicum L. plants was studied. The results obtained showed that the R. sativus powder at 2 and 4% concentrations, was effective in decreasing the average number of O. ramosa tubers which reached 4.20 and 2.00 tubers/plant, respectively, compared to the control which was 48.80 tubers/plant, and decreased the average length of Orobanche branches to 2.67 and 0.53 cm, respectively, compared to 10.33 cm for the control. Furthermore, Orobanche dry weight reached 0.80 and 0.02 g, respectively, in response to the two concentrations of the radish powder, compared to 4.24 g for the control. There was no negative effect on the growth and weight of tomato plants when treated with radish powder, suggesting the effectiveness of radish leaves powder added to the soil as an effective biological material in reducing the incidence of branched broomrape Orobanche ramose L., and protecting tomato plant Solanum lycopersicum L. from this parasitic weed. Keywords: Solanum lycopersicum, Orobanche ramose, Allelopathic effect, Raphanus sativus, radish
