“…Furthermore, Bacillus mojavensis increased the yield of sweetcorn by 16%, while B. subtilis yielded an increase of 13.8%, and B. pumilus produced an increase of 11.8%, with higher protein and fiber contents in the grains to the control [4]. Phares et al [47] and Kaur et al [48] stated that phosphate-solubilizing bacteria (PSB) are important components of sustainable agriculture, since PSB increased the availability of phosphate by mineralizing the insoluble fraction of inorganic phosphate. The authors noted considerable improvements in the plant-growth parameters, phosphorus (P) content, and soil availability of P with bacterial treatments using Bacillus spp., Pseudomonas spp., and Arthrobacter spp., in potatoes and maize.…”

The plant-growth-promoting rhizobacteria (PGPR) in the rhizosphere affect plant growth, health, and productivity, as well as soil-nutrient contents. They are considered a green and eco-friendly technology that will reduce chemical-fertilizer usage, thereby reducing production costs and protecting the environment. Out of 58 bacterial strains isolated in Qassim, Saudi Arabia, four strains were identified by the 16S rRNA as the Streptomyces cinereoruber strain P6-4, Priestia megaterium strain P12, Rossellomorea aquimaris strain P22-2, and Pseudomonas plecoglossicida strain P24. The plant-growth-promoting (PGP) features of the identified bacteria involving inorganic phosphate (P) solubilization, the production of indole acetic acid (IAA), and siderophore secretion were assessed in vitro. Regarding the P solubilization, the previous strains’ efficacy reached 37.71%, 52.84%, 94.31%, and 64.20%, respectively. The strains produced considerable amounts of IAA (69.82, 251.70, 236.57, and 101.94 µg/mL) after 4 days of incubation at 30 °C. Furthermore, the rates of siderophore production reached 35.51, 26.37, 26.37, and 23.84 psu, respectively, in the same strains. The application of the selected strains in the presence of rock phosphate (RP) with tomato plants under greenhouse conditions was evaluated. The plant growth and P-uptake traits positively and significantly increased in response to all the bacterial treatments, except for some traits, such as plant height, number of leaves, and leaf DM at 21 DAT, compared to the negative control (rock phosphate, T2). Notably, the P. megaterium strain P12 (T4), followed by R. aquimaris strain P22-2 (T5), revealed the best values related to plant height (at 45 DAT), number of leaves per plant (at 45 DAT), root length, leaf area, leaf-P uptake, stem P uptake, and total plant P uptake compared to the rock phosphate. The first two components of the PCA (principal component analysis) represented 71.99% (PCA1 = 50.81% and PCA2 = 21.18%) of the variation at 45 DAT. Finally, the PGPR improved the vegetative-growth traits of the tomato plants through P solubilization, IAA, and siderophore production, and ameliorated the availability of nutrients. Thus, applying in PGPR in sustainable agriculture will potentially reduce production costs and protect the environment from contamination by chemical fertilizers and pesticides.

According to the measurements of Phares et al [ 57 ], the amount of applied NPK fertilizer can also be reduced by certain strains from genera Pseudomonas in corn cultivation, and Ummara et al [ 58 ] reported that the application of PGPB in corn also increases diesel oil tolerance. Citrobacter freundii strain LMG 3246, Citrobacter braakii DSM 17596, and strain G5 are compatible as PGPB and can be developed as biofertilizers [ 59 ].…”

Plant growth-promoting bacteria (PGPB) and other living organisms can help with the challenges of modern agriculture. PGPB offer ever-expanding possibilities for science and commerce, and the scientific results have been very advanced in recent years. In our current work, we collected the scientific results of recent years and the opinions of experts on the subject. Opinions and results on soil–plant relations, as well as the importance of PGPB and the latest related experiences, are important topics of our review work, which highlights the scientific results of the last 3–4 years. Overall, it can be concluded from all these observations that the bacteria that promote plant development are becoming more and more important in agriculture almost all over the world, thus, promoting more sustainable and environmentally conscious agricultural production and avoiding the use of artificial fertilizers and chemicals. Since many mechanisms of action, namely biochemical and operational processes, are still under investigation, a new emerging scientific direction is expected in the coming years with regard to PGPB, microbial, and other plant growth-stimulating substances, in which omics and microbial modulation also play a leading role.

“…Because of the low NPK compound fertilizer, content (16:16:16 %) of N, P, and K its save for crops in each phase. [12] revealed that sorghum must absorb sufficient amount of N, P, and K during the vegetative stage to obtain optimal growth [13]. In addition to soil amendments and NPK fertilization, productivity can be increased in Ultisol cultivation land by applying liquid organic fertilizer and eco enzymes.…”

The increase in world population must be accompanied by the increase of food production. Diversification of food is also needed to support a healthy and productive world community. Increasing food diversification is conducted by increasing soil fertility. Improvement of soil fertility was carried out by using soil amendments and NPK fertilization, as well as using eco enzymes on sorghum on Ultisol soil. This study was using factorial RBD design split-split plot 3 × 2 × 2 with three replications and 108 pots with 10 kg Ultisol pot-1. The main plot consisted of soil amendments (no amendment, biochar, compost), sub-plots, NPK (600, 900 kg ha-1), split-split plot, eco enzyme (sprayed eco enzyme once week-1 and every two weeks sprayed). The results showed that there were interactions between soil amendments and eco enzymes on soil pH and NPK. There is an interaction between NPK and eco enzymes on soil pH, soil EC, and sorghum leaf chlorophyll. There is an interaction between soil amendments, NPK, and eco enzymes on N, P, and K content and yield potential. The use of soil amendments, NPK, and eco enzymes effectively improves Ultisol fertility and sorghum yields to support food diversification.
