Abstract

In order to investigate the effect of biofertilizers on growth indices of maize (Zea mays L. ) in lead-contaminated soils, a factorial experiment with three iterations was conducted, based on a completely randomized design in a greenhouse of the soil science department at Zanjan University in 2015. Factor I included soil contamination levels of lead (0, 50, 100, 200, and 400 mg / kg soil) with Factor Ι Ι being no inoculation (C), inoculation with soluble bacteria Phosphate (Pseudomonas putida) (P), inoculation with Funneliformis mosseae (M), inoculation with mycorrhizal fungus Funneliformis mosseae + phosphate solubilizing bacterium (M + P), inoculation with Rhizophagus intraradices mycorrhizal (I), and inoculation with mycorrhizal fungi Rhizophagus intraradices + phosphate-solubilizing bacterium (I + P). The measured parameters were leaf chlorophyll index, plant height, fresh and dry weight of root and shoot, phosphorus and potassium of root, and the lead content in the shoots and roots. It has been shown that inoculation of soil with mycorrhizal fungi and bacteria improve plant growth and yield indices in the absence of lead. Inoculation with mycorrhizal fungus Funneliformis mosseae + phosphate-solubilizing bacterium (I + P) increase leaf chlorophyll index (11. 65%), root phosphorus (161. 5%), shoot phosphorus (237%), root potassium (35. 6%), and shoot potassium (62. 01%), compared to the no-inoculation treatment (control). Also, biofertilizers are proven capable of increasing the amount of absorbed lead in the plant root, compared to the control treatment by 61. 9%. In other words, they have been able to retain the absorbed lead from the soil by the plant root. According to the obtained results, at a critical concentration of lead (400 mg/kg soil), biofertilizers could not have a beneficial and increasing effect on chlorophyll index, height, and fresh and dry weight of the roots and shoots. However, at lower concentrations of Pb, they are able to decrease the harmful and adverse effects of these Heavy metals on the shoots and roots of the plant.
