Phytotoxicity of sewagewater and leachate of solid waste on seed germination and seedling growth of Vicia faba L. (Faba bean)‎

الملخص EN

The present study was conducted in greenhouse of Science College during January to April 2017 in order to evaluate the effect of sewagewater and solid waste leachate used for irrigation on some vegetative growth and seed germination of Faba bean (Vicia faba L.) plant.

The results showed that pH values of sewagewater was near neutrality while leachate was in acid side of neutrality.

Electrical conductivity (EC) of leachate pass 8000 μS.cm-1.

In most vegetative growth characters of Faba bean plant (Plant height, root dry weight, numbers of flowers, legumes and nodules) the sewagewater treatment record the high values in compared to control treatment.

On the other hand, leachate treatments had very harmful effect on plant vegetative growths with lowest value in most variables (except chlorophyll content) with significant differences (P≤0.05) between it, especially at the last months of growth the bean plant of leachate treatment exposed to wilting and dead with zero values recorded for many studied variables (root dry weight and numbers of legumes and nodules).

Same results were obtain for seed germination assay irrigated by leachate with lowest germination rate and highest inhibition of germination.
