Abstract:
The research was carried out by randomized complete sectors design with five replications in a greenhouse belonging to the Faculty of Agricultural Engineering at Tishreen University in fall season of 2019, to study the effect of dry powder of sticky fleabane Inulla viscosa L. leaves mixed with soil with concentrations 1, 2, and 4% on the growth of tomato plants Lycopersicum esculentum L. On the one hand, and in the germination of Orobanche ramose L. seeds, on the other hand. The results showed the stimulating effect of the three concentrations used of Inulla viscosa on seeds germination of Orobanche ramose, and an increasing in tubers formed number and in biomass of O.ramosa plants related directly with the increase of the tested concentrations compared to the control infected with the branched broomape, where the average number of tubers at the three studied concentrations was 49.25, 78.00, 69.50 tuber/plant respectively compared to the control 28.50 tuber/plant, and the average of dry weight of the O.ramosa plants recorded 6.89, 8.49, 8.88 g, respectively, compared to the control 1.38 g.Noting that the tested concentrations of Inulla viscosa did not affect the health and vitality of the tomato plants treated with them.
Key words: tomato, Lycopersicum esculentum, broomrape, Orobanche ramose, sticky fleabane, Inulla viscosa, Allelopathic effect.
