“…In this regard, Hozzein et al [62] found marked elevation in growth and photosynthesis of barley, wheat, maize, sorghum and oat plants treated with Actinobacteria. Also, Dicko et al [63] and Govindappa et al [64] reported significant increase in biomass of maize inoculated with PGPB as compared to non-inoculated plants. Such increase in growth and photosynthesis due to actinobacterial treatment has been attributed to enhancement in photosynthetic pigment synthesis and nitrogen accumulation [47,62] and activation of enzymes necessary for chlorophyll biosynthesis and other metabolic pathways [65,66].…”

Drought stress is threatening the growth and productivity of many economical crops. Therefore, it is necessary to establish innovative and efficient approaches for improving crop growth and productivity. Here we investigated the potentials of the cell-free extract of Actinobacteria (Ac) isolated from a semi-arid habitat (Al-Jouf region, Saudi Arabia) to recover the reduction in maize growth and improve the physiological stress tolerance induced by drought. Three Ac isolates were screened for production of secondary metabolites, antioxidant and antimicrobial activities. The isolate Ac3 revealed the highest levels of flavonoids, antioxidant and antimicrobial activities in addition to having abilities to produce siderophores and phytohormones. Based on seed germination experiment, the selected bioactive fraction of Ac3 cell-free extract (F2.7, containing mainly isoquercetin), increased the growth and photosynthesis rate under drought stress. Moreover, F2.7 application significantly alleviated drought stress-induced increases in H 2 O 2 , lipid peroxidation (MDA) and protein oxidation (protein carbonyls). It also increased total antioxidant power and molecular antioxidant levels (total ascorbate, glutathione and tocopherols). F2.7 improved the primary metabolism of stressed maize plants; for example, it increased in several individuals of soluble carbohydrates, organic acids, amino acids, and fatty acids. Interestingly, to reduce stress impact, F2.7 accumulated some compatible solutes including total soluble sugars, sucrose and proline. Hence, this comprehensive assessment recommends the potentials of actinobacterial cell-free extract as an alternative ecofriendly approach to improve crop growth and quality under water deficit conditions.

“…To determine the plant growth promoting characteristics, the followings tests have been performed: promoting plant growth; the production of chitinase (Han et al, 2009), Indole Acetic Acid (Bric et al, 1991), siderophores (Schwyn and Neilands, 1987;Milagres et al, 1999), Cyanuric acid (Babana, 2003), and phosphate solubilization (Babana and Antoun, 2006;Dicko et al, 2018;Kassogué et al, 2015).…”

The objective of this study was to improve rice and maize yields using native Azospirillum-based biofertilizer. To reach this objective, samples of rhizosphere soil, non-rhizosphere soil and roots of maize plants were collected from the particular locations of Samanko and Bamako of the south Mali. Thirty-three different colonies of bacteria were isolated from the different samples. Based on their better growth in nitrogen free semi-solid medium, their morphological, biochemical and plant growth promotion characteristic, ten bacterial isolates were identified as Azospirillum isolates following the Bergey's Manual of Determinative Bacteriology. Ten isolates were selected: Az1, Az2, Az3, Az4, Az5, Az6, Az7, Az8, Az9 and Az10. Strain Az6 showed great potential on both rice and maize production. Therefore, this strain is suggested for large scale rice and maize fields' application. While the Azospirillum sp. Az5, Az6 and Az10 strains are suggested for large scale application in maize field, which may reduce production cost. Top dressing with 25% of the recommended nitrogen-fertilizer was found to decrease maize grain yield.

“…In the work undertaken [20], the improvement in wheat yield was attributed to the co-inoculation of Bacillus thuringiensis and Serratia sp. Similarly, [21] [22] noted that inoculation of corn seeds with strains of Bacillus polymyxa, Pseudomonas alcaligenes and Actinomycetes sp. (O19-AHB12) significantly improved the dry weight of maize plants by 19% to 52%, total maize biomass by 38% and the weight of 1000 corn seeds by 74.72% compared to controls.…”

The use of microbial technologies in agriculture is rapidly expanding with the discovery of new bacterial strains effective in improving plant growth. In this study, we tested and highlighted the efficacy of PGPR (Plant Growth Promoting Rhizobacteria) alone or in a consortium on maize growth. For this purpose, a greenhouse experiment was carried out in pots containing sterilized ferruginous soil for 30 days. The corn seeds of the EVDT 97 SRT C1 variety were inoculated with bacterial suspensions of concentration 10 8 UFC/ml. The experimental device was a random block of 16 three-repeat treatments. The incidence of PGPR inoculated strains is assessed on the biomass growth and yield parameters of maize. At the end of the trial, the results showed that inoculation stimulated plant growth and development and resulted in a significant increase in the height, diameter at the collar, leaf surface and dry weight of aerial biomass of 20.15%, 21%, 32.77% and 37.73% respectively compared to controls, especially in corn plants inoculated with B. thurengiensis + B. panthéthonicus + S. marcescens and Pseudomonas cichorii + Pseudomonas putida + Pseudomonas syringae. These results show the potential of using these rhizobacteria as biological inoculants to improve maize productivity in Benin.
