AbstractThe allelopathic effect was studied to sequence varieties of cucumbers in soils cultivated previously with plants (broad bean, peas, chickpeas), as the results of this study showed that allelopathy had an effect on germination and growth of cucumbers, as previously cultivated soils caused legumes (broad bean, peas, chickpeas) significantly reduced. In the percentage of germination and germination speed, while it caused an increase in the height and dry weight of the vegetative group of cucumber varieties tested in most treatments, the highest percentage increase was 24% for the cultivars of the cultivar Beitha alpha after the chickpea plant. And on the role of allelopathy and its effect on the modulus of division and the phase factor of the cells of the roots of the roots of the cucumber seedlings gave a difference in their effect between the increase and the decrease, as the soil planted with chickpeas caused an increase in the division factor and the coefficient of the introductory phase of the Biyar dalta class, which was accompanied by a decrease in the coefficients of the separation and the final phase, accompanied by a decrease in Root total length.
The study also showed an increase in the number of root branching of the cultivated cultivars following the broad bean plant, accompanied by an increase in the length of the vegetative system.
