Aim: Hexavalent chromium (Cr ) is one of the most toxic heavy metals that have deteriorating effects on the growth and quality of the end product of wheat. Consequently, this research was designed to evaluate the role of Bacillus subtilis and phosphorus fertilizer on wheat facing Cr stress.
Methods And Results: The soil was incubated with Bacillus subtilis and phosphorus fertilizer before sowing. The statistical analysis of the data showed that the co-application of B. subtilis and phosphorus yielded considerably more significant (p < 0.05) results compared with an individual application of the respective treatments. The co-treatment improved the morphological, physiological and biochemical parameters of plants compared with untreated controls. The increase in shoot length, root length, shoot fresh weight and root fresh weight was 38.17%, 29.31%, 47.89% and 45.85%, respectively, compared with untreated stress-facing plants. The application of B. subtilis and phosphorus enhanced osmolytes content (proline 39.98% and sugar 41.30%), relative water content and stability maintenance of proteins (86.65%) and cell membranes (66.66%). Furthermore, augmented production of antioxidants by 67.71% (superoxide dismutase), 95.39% (ascorbate peroxidase) and 60.88% (catalase), respectively, were observed in the Cr - stressed plants after co-application of B. subtilis and phosphorus.
Conclusion: It was observed that the accumulation of Cr was reduced by 54.24%, 59.19% and 90.26% in the shoot, root and wheat grains, respectively. Thus, the combined application of B. subtilis and phosphorus has the potential to reduce the heavy metal toxicity in crops.
Significance And Impact Of The Study: This study explored the usefulness of Bacillus subtilis and phosphorus application on wheat in heavy metal stress. It is a step toward the combinatorial use of plant growth-promoting rhizobacteria with nutrients to improve the ecosystems' health.

Plant growth-promoting rhizobacteria (PGPR) are known to enhance the productivity, development, yield, and soil health of both medicinal and vegetable crops. The present investigation evaluated the influence of PGPR on the growth attributes and physiological parameters of ginger, alongside soil quality, under field conditions. Field trials were carried out over three consecutive years (2020 to 2022), with ginger being planted each March.

The demand for bioenergy resources continues to grow due to increased emerging economic value and emission trading systems. On top of that, energy crop (EC) resources are key to addressing the interconnected global challenges of sustainable development with the adoption of Renewable Portfolio Standard (RPS) and the post-Paris Agreement in Korea. Current research on interactions between EC and plant growth-promoting rhizobacteria (PGPR) emphasizes the energy potential regarding greatly enhanced ecological and economic effects that may increase in the future.

This study assessed microalgae monocultures/consortia with brassinolide (BR) for aquaculture wastewater treatment; co-cultures of Scenedesmus obliquus, Bacillus subtilis, Phanerochaete chrysosporium showed superior pollutants removal efficiencies. In medium-concentration wastewater, on Day 7, 91 % removal efficiency was achieved for chemical oxygen demand (COD), 94 % for total nitrogen (TN), 92 % for total phosphorus (TP), 94 % for Zn, 96 % for Cu, and over 99 % for tetracycline (TC). The three-culture system outperformed the microalgae monoculture control, with the latter reaching only 82 % COD, 85 % TN, 83 % TP, 67 % Zn, 63 % Cu, and 87 % TC removal efficiency under the same conditions.

Fusarium culmorum is a soil-borne fungal pathogen causing root and stem rot, seedling blight, and significant yield losses in small grain cereals, including wheat. This study aimed to evaluate the antifungal potential of Bacillus subtilis ED24, an endophytic strain isolated from Ziziphus lotus (L.) roots, and its effects on wheat growth and yield under controlled conditions.
