| dc.description.abstract | Aims and scope: Phosphorus (P) is a limiting factor in crop growth and, due to its low availability, P-deficiency in soils is widespread, and as such the successive application of P- fertilizers to maintain crop production has occurred, leading to severe environmental problems. The development and application of environmentally friendly biotechnological approaches as alternatives to chemical fertilizers has gained considerable interest in agricultural practices worldwide. The harnessing of Phosphate Solubilizing Bacteria (PSB) seems to be of utmost importance towards the reverse of the current use of large amounts of P fertilizers, since they can stimulate plant growth in particular through the conversion of bound P in soil into bioavailable P forms. This work aimed to evaluate the ability of PSB to enhance Zea mays growth in an agricultural P-deficient soil. Methodology: P solubilizing strains Rhodococcus sp. EC35 (B1), Pseudomonas sp. EAV (B2) and Arthrobacter nicotinovorans EAPAA (B3) were inoculated in maize growing in P-deficient soils without P fertilization and amended with soluble - KH2PO4 and insoluble P - Ca3(PO4)2; Plant dry biomass and P accumulation in plant tissues were determined after 90 days; Available P in rhizosphere soils were determined at the end of experiment; The persistence of inoculated strains in soils was evaluated by Denaturing Gel Gradient Electrophoresis (DGGE). Conclusions: PSB significantly enhanced Z. mays growth and P uptake in P-deficient soils; Rhodococcus sp. EC 34, Pseudomonas sp. EAV and A. nicotinovorans EAPAA may be used as biofertilizers and constituting an interesting alternative to the application of phosphatic fertilizers in P-deficient soils, reducing costs and improving crop yields. | eng |
