“…That comes in agreement with our findings because the strains of B. subtilis, B. pumilus and P. megaterium also presented significantly higher values of maize dry weight and chlorophyll content. Other strains of B. subtilis, B. pumilus and B. megaterium ( P. megaterium ) had been also found to have a positively effect on chlorophyll content 40 . The chlorophyll content seems to be positively affected by various strains of these genera and thus raising the question if this is a genera characteristic effect on maize plants.…”

The use of plant growth promoting bacteria (PGPB) is increasingly gaining acceptance from all the stakeholders of the agricultural production. Different strains of PGPB species had been found to have a vast variety of mechanisms of action, while at the same time, affect differently a variety of crops. This study investigated the effectiveness of ten PGPB strains, on sweet corn cultivation under Mediterranean soil and climatic conditions. A field experiment that followed a completely randomized design was conducted at the region of Attica at Oropos. The results indicated that B. mojavensis increased yield by 16%, B. subtilis by 13.8%, B. pumilus by 11.8% and B. pseudomycoides by 9.8% compared to control. In addition, the harvested grains of the plants treated with B. mojavensis, B. subtilis and B. pumilus presented the highest values of protein and fiber content. Moreover, in most of the cases, high values of photosynthetic rate, transpiration rate and stomatal conductance during the cultivation period, resulted in high productivity. Regarding the texture, the size, the sphericity and the ash content of corn grains, it was found that they were not influenced by the application of different treatments of PGPB. The use of certain strains of PGPB, under specific soil and climatic conditions could contribute to better understand which strains are better suited to certain crops.

“…Pseudarthrobacter sp. ER25 is closely related to P. oxydans, which showed no significant effects on maize root dry weight (Abadi et al, 2020) and produced lower germination in seeds of Salicornia ramosissima inoculated with it (Mesa-Marín et al, 2019).…”

Amelioration of Saline Stress on Chia (Salvia hispanica L.) Seedlings Inoculated With Halotolerant Plant Growth-Promoting Bacteria Isolated From Hypersaline Environments

The rhizosphere and microbiome of halotolerant plants could be crucial for alleviating salinity stress during plant growth. The aims of this work were (1) to isolate bacteria from rhizosphere and bulk soil samples from the Salar del Hombre Muerto (Catamarca, Argentina), (2) to characterize different plant growth-promoting (PGP) activities produced by these bacterial isolates, and (3) to evaluate their effect on the initial growth of chia (Salvia hispanica L.) under saline stress. A total of 667 microorganisms were isolated, using different culture media with NaCl, and their abilities for nitrogen fixation, phosphate solubilization, siderophores production, and indole-3-acetic acid production were evaluated. Thirteen strains were selected for showing all the tested PGP activities; they belonged to the genera Kushneria, Halomonass, Pseudomonas, Planomicrobium, and Pseudarthrobacter. The strains Kushneria sp. and Halomonas sp. showed the highest salinity tolerance (from 50 to 2,000 mM NaCl) and biomass and biofilm production. Chia seeds were treated with six of the first 13 selected strains to evaluate their plant growth-promoting effect under saline stress (without and with 50 and 100 mM NaCl). Halomonas sp. 3R.12 and Kushneria sp. T3.7 produced heavier seedlings with a balanced shoot/root length ratio, while Pseudomonas sp. AN23 showed the best effect upon chia seedlings, with a morphological response similar to non-stressed seedlings. On the other hand, seedlings displayed no responses when inoculated with Planomicrobium sp. 3S.31 and Pseudarthrobacter sp. ER25. This study contributes to the knowledge on microorganisms from hypersaline environments as plant growth promoters for their use in the production of salt-sensitive crops, among other potential uses.

“…Stimulation of root growth leads to a larger area for accessing nutrients [64]. Recently, Abadi et al, [65], found a wide range of PGPB in maize phyllosphere. M. arborescens and S. maltophilia isolates produced indole-3-acetic acid (IAA) and positively affects the growth traits.…”

Under field conditions, wheat response to organic amendments and B. megatherium inoculation as well as different rates of natural rock P fertilizer (NRP) was traced. Animal manure, peanut straw and quail feces were added in combination with P0, P50 and P100 kg ha -1 levels and both factors were tested with or without bacterial inoculation. The grain yield of wheat was higher with 192 kg ha -1 than rate 96 kg ha -1 while both of them surpassed the un-fertilized control. Inoculated plants, under all NRP levels, resulted in a higher grain yield than the un-inoculated ones. In inoculated plants, grain yield was significantly higher with quail feces additives than animal manure and peanut residues. B. megatherium induced slight increases in N uptake as compared to the un-inoculated plants. However, peanut residues resulted in N uptake values slightly higher than either quail feces or animal manure. Increasing rock-P levels increased N uptake over the unfertilized or those received 96 kg ha -1 treatments. Supply with quail feces had increased P uptake over those resulted from peanut residues and animal manure. Quail feces resulted in a relative increase of P uptake by about 5% and 15%; 16% and 19%; 17% and 4% over peanut and animal manure for P0, P50 and P100, respectively. Inoculation with B. megatherium had, to some extent, enhanced K uptake by grains comparable to the un-inoculated one when plants treated with peanut residues. Nitrogen portion derived from (Ndforg) peanut straw and quail feces to inoculated plants was relatively increased, on mean average basis, by about 19% and 16%, respectively over the un-inoculated plants. Efficient use of N derived from peanut straw, quail feces (Org-NUE %) and urea-NUE% by inoculated plants slightly increased under all rock-P levels over those of the un-inoculated plants.
