Enhanced phytoremediation of olive mill wastewater "Zibar" using plant growth promoting rhizobacteria (PGPR) with barley and clover
Publication Type
Conference Paper

Olive mill wastewater (OMWW) has negative environmental impact. Utilization of OMWW in irrigation is difficult due to the toxic effect. Different phytoremediation methods were used  to improve the  use of OMWW in irrigation.

In this research, PGPRs were implemented to investigate their efficiency of improving the phytoremediation technique for plants irrigated with olive mill waste water. Two strains of PGPR (UW3, Pseudomonas putida(A). UW4, Pseudomonas putida(C) with unassigned one (B)) were used with Barley (Hordeum valgare L.) and clover plants (Trifolium sp.). All trials were carried in a designed green house in faculty of agriculture at An-Najah national university in Tulkarem for 30 days. Plants irrigated with different concentration of OMWW (0%, 10%, 25%, and 50%). Seeds of  both  barley  and clover  irrigated by different concentration of olive mill waste water, showed significant differences in germoination among the concentration levels of OMWW. It was notable that the OMWW has negative impact on seed germination of both plants.
