Abstract The present work was carried out to lead contaminated soil remediation using some immobilizing. This included pots experiments were conducted on maize at the Experimental green house of Faculty Agriculture (Saba-Basha) Alexandria University, Egypt, during the growing season of 2019. The experiment was designed as spot plot design with four replicates. Each replicate contained 16 treatments. The treatments of the two studied factors can be illustrated as follows: A) Main plots (lead levels) Control 250 mg/kg 500 mg/kg B) Sub-plots (considers) Control Zeolite at 10 g/kg Zeolite at 20 g/kg Zeolite at 40 g/kg Compost at 10 g/kg Compost at 20 g/kg Compost at 40 g/kg Triple super phosphate at 10 g/kg Triple super phosphate at 10 g/kg Triple super phosphate at 10 g/kg The result of this experiment could be summarized as follows: 5.1 Growth characters 5.1.1 Plant height (cm) Significantly increased of plant height recorded with the control treatment, as compared with all concentrations of lead (250 and 500 mg/kg), which recorded the minimum values of plant height, during 2019 season. Zeolite, compost and triple super phosphate concentrations up to (0.40 mg/kg), recorded the highest mean values of plant height, as compared with untreated treatment (control) which gave the minimum values of plant height, during 2019 season. The interaction between lead concentration and condenser (zeolite, compost and triple super phosphate) was highly significant on plant height, during 2019 season. 5.1.2 Shoots fresh weight (g) Increased shoots fresh weight was recorded with the control, as compared with lead treatments (250 and 500 mg/kg), which recorded minimum shoots fresh weight, during 2019 season. Maximum shoots fresh weight recorded with concentration up to (0.40 mg/kg) of zeolite, compost and triple super phosphate, as compared with the control treatment which gave the minimum values of shoot fresh weight, respectively, during 2019 season. |
