Nowadays, using sewage wastewater in the irrigated agriculture causes hazardous environment impacts. Assessment of these negative effects is vital issue to prevent heavy metals to be introduced in the food chain. Field and laboratory studies were conducted at Ellwan, Mangabad and El-Madabegh villages, Assiut Governorate, in order to evaluate heavy metals concentrations in the edible parts of carrot, turnip and onion plantswhich were irrigated with sewage water (SW). The obtained results indicated that, the soils of the studied villages were contaminated by heavy metals. The concentrations of Zn, Cu, Pb, Cd and Ni concentrations in the edible portion of thesevegetables plants ranged between 45-70, 13-19, 3.8-6.2, 2.85-3.85 and 2-6 mgkg -1 , respectively. The obtained results showed that the concentrations of Pb, Cd and Ni in the edible plants were higher than the permissible limit levels but those of Zn and Cu were within the safe limit levels. It is worthy to mention that the irrigated edible vegetable crops especially onion, turnip and carrot with SW should be avoided. This study highlights the potential hazard for human health due to uptake of high concentrations of heavy metals especially Ni, Cd and Pb by the studied vegetable crops.

The objective of the research was to improve the properties of grape cuttings to obtain strong and healthy plantlets and overcome the problems they encounter during cultivation in clay and sandy soils to become vigorous and healthy trees without using chemical fertilizer. This experiment investigated how to vermicompost tea and Plant Growth-Promoting Rhizobacteria (PGPR), individually or in mixed form, influenced the characteristics of grape cuttings cultivated in clay and sandy soils. Some physical and chemical parameters for cutting were measured such as parameters of vegetative growth and root, chemical parameters of plant, and soil parameters as CaCo3 % content, and total count bacteria CFU/g. The results proved that the type of soil affected the growth of cuttings. All treatments gave significant differences, compared with the control. Sometimes significant differences were found among treatments on parameters, and sometimes not. In general, the best effect on the growth of the cuttings was in a treatment that included the combination of vermicompost tea and PGPR, whether cultivated in sandy or clay soil, in both successive growing seasons.
