Abstract
Field experiment at EI-Fayoum Governorate was carried out to examine the impacts of interactions between Ps. putida and arbuscular mycorrhizal (AM) fungi and their effects on elements distribution in soil and faba bean plant parts grown under field conditions in the presence of 25 or 50% of the recommended mineral fertilizers (NPK). The soil before cultivation was polluted with copper and zinc in total form as well as with Cu, Fe and Zn in available forms. During plant growth, the soil was polluted with the investigated elements except Cu. The best treatment to decrease the polluted soils is the inoculation of plants with AM fungi plus Ps. putida and fertilized with 50% NPK. All parts of plant are polluted in the two stages in case of using 25% mineral.fertilizers, while roots and leaves at mature stage under 50% mineral fertilizers, in untreated plants. The best treatment to decrease Cu pollution is the inoculation with AM fungi + 25% NPK followed by AM fungi+Ps.+50%NPK in mature stage. All plant parts in all treatments in this study are polluted with iron. The best treatment to decrease Fe pollution, is the fertilization with 50% of the recommended NPK +AM fungi+ Ps. All plant parts are polluted with Pb and the best treatment to decrease Pb pollution is using 25% NPK+ AM fungi in mature stage. The concentrations of zinc in all young plant parts are higher than 400 mg/kg then decreasing with plant growth. Using 50% NPK +AM fungi is the best treatment to decrease Zn pollution.
