“…Azospirillum cells do not disperse with percolating water but are absorbed onto soil particles. Furthermore, passive possible dispersion by water in semiarid conditions lacking sufficient water where Azospirillum performed best (Caceres et al 1996) cannot explain how the entire root system is colonized. In plant-free, watersaturated soils, Azospirillum stayed at the inoculation site and did not move (Bashan and Holguin 1995).…”

This review presents a critical and comprehensive analysis of the developments in environmental and physiological studies related to Azospirillum interactions with plants based on information published between 1990 and 1996. It was designed as an update of a previous review with a similar scope. Apart from an update, this review emphasizes the central issues of Azospirillum research today, such as coinoculation with other microorganisms and hormonal studies, shows the less researched areas, and proposes possible avenues for the exploitation of this bacterium in areas other than agriculture.Key words: Azospirillum, bacterial inoculation, plant–bacteria interaction, plant growth promoting rhizobacteria, rhizosphere bacteria.

“…Similarly, increased nutrient concentrations in wheat due to inoculation were reported in Refs. [5,118,[162][163][164][165]. It is pointed out by Mäder et al that microbial inoculants have been shown to be a valid option for sustainable high quality wheat production in low-input areas, promising to improve the nutritional status and health of the rural population [163].…”

Free-living plant growth-promoting rhizobacteria (PGPR) have favourable effect on plant growth, tolerance against stresses and are considered as a promising alternative to inorganic fertilizer for promoting plant growth, yield and quality. PGPR colonize at the plant root, increase germination rates, promote root growth, yield, leaf area, chlorophyll content, nitrogen content, protein content, tolerance to drought, shoot and root weight, and delayed leaf senescence. Several important bacterial characteristics, such as biological nitrogen fixation, solubilization of inorganic phosphate and mineralization of organic phosphate, nutrient uptake, 1-aminocydopropane-1-carboxylic acid (ACC) deaminase activity and production of siderophores and phytohormones, can be assessed as plant growth promotion traits. By efficient use, PGPR is expected to contribute to agronomic efficiency, chiefly by decreasing costs and environmental pollution, by eliminating harmful chemicals. This review discusses various bacteria acting as PGPR, their genetic diversity, screening strategies, working principles, applications for wheat and future aspects in terms of efficiency, mechanisms and the desirable properties. The elucidation of the diverse mechanisms will enable microorganisms developing agriculture further.

“…To investigate the practical use of Azospirillum as a plant biofertilizer, wheat field trials were carried out at different locations of country. The local isolate A. brasilense strain Az39, which was obtained from wheat roots in the province of Córdoba, showed a consistent positive effect on the yield of different cultivars, from 13.4 to 33% increase over the control in three growing cycles tested (Rodríguez Cáceres et al 1996). In addition, it is known that increases in crop yield derived from Azospirillum inoculation are consistently obtained when water is deficient (Fig.…”
