“…These results are in line with the ndings of Akhtar et al [55] and Khalil et al [73], who demonstrated a marked increase in the uptake of K, N, and P in wheat treated with SiO 2 NPs and PGPB that manifested in direct proportion to the concentration of applied SiO2 NPs. Rezakhani et al [29] also reported the concentrations of Si and P in wheat shoots after using different Si and Pseudomonas sp. concentrations.…”

“…Rainfed wheat seeds (Qaboos cultivar) were purchased from the Seedling and Seed Research Institute, Lorestan, Iran. For disinfecting the seeds, they were soaked in 96% ethanol for 2 s and in 2% sodium hypochlorite solution for 90 s and washed with sterile distilled water 6-7 times [29]. The bacterial strains were initially cultured on nutrient agar (NA medium) to prepare the bacterial inoculum.…”

“…For example, the combined use of phosphate-dissolving bacteria (PFDB), a group of PGPB, and Si could enhance P availability and uptake in plants, including wheat. These approaches offer promising solutions to combat P de ciency, particularly in environments where P availability is limited or compromised [29].…”

Water deficit stress significantly reduces grain yield in bread wheat, requiring improved tolerance in cultivars. Despite recent breeding advancements, enhancing tolerance remains crucial. Plant growth-promoting bacteria (PGPB) and silicon (Si) independently boost drought resistance through different mechanisms, but their combined effects are understudied. This research explored the combined impacts of silicon dioxide nanoparticles (SiO2 NPs) and native PGPB on wheat's morphophysiological and nutritional responses under water deficit stress. The study tested various SiO2 NP concentrations (control, soil application of 100 and 200 mg/kg, and foliar application of 200 mg/kg) and PGPB strains (no bacterium, Pseudomonas fluorescens p-187, and Pseudomonas putida p-168). Results showed that SiO2 NPs significantly improved wheat tolerance to water stress, increasing shoot dry weight by 4.40 g/pot with 100 mg/kg Si-NPs and Pseudomonas fluorescens p-187 compared to the control, and root dry weight by 1.05 g/pot with foliar application of 200 mg/kg Si-NPs and Pseudomonas putida p-168. SiO2 NPs and PGPB also boosted N, P, K, and Si concentrations in wheat shoots, reduced malondialdehyde content, and increased superoxide dismutase and glutathione peroxidase activities. The best performance was achieved with 200 mg/kg Si-NPs and Pseudomonas fluorescens p-187. The study confirms that combining Si sources with PGPB effectively enhances wheat's drought tolerance. This synergistic approach offers an environmentally sustainable strategy to bolster crop resilience against water deficit stress, ensuring better wheat yield in drought-prone conditions.

“…The related study shows that Bacillus spp. can improve plant growth through the production of IAA and ACC deaminases to improve plant growth, and these enzymes are mainly involved in improving the plant root system (Rezakhani et al, 2022). On the other hand, the microbial degradation of organic matter in the vinegar residue improved the soil microenvironment of the root system of wheat seedlings.…”

Saline land rehabilitation plays a crucial role in expanding arable land resources and ensuring food security. To achieve green and sustainable improvement of saline and alkaline land, the present study utilizes vinegar residue waste composted with inter-root bacteria PGPR (phosphorus solubilizing, potassium solubilizing, and nitrogen fixing bacteria) to produce organic fertilizers that are beneficial to plants, thus rehabilitating saline and alkaline land. The total nutrient content (Σ (N + P2O5 + K2O) of the heap at the end of composting increases by 49.85%. PKN-VR (vinegar residue compost with added phosphorus solubilizing, potassium solubilizing, and nitrogen-fixing bacteria) treatment group significantly increases the stem length (55.99%), root length (54.29%), fresh weight (71.4%), and dry weight (57.9%) of wheat seedlings in the saline soil. In addition, the compost products increase the content of chlorophyll (62.2%), proline (94%), and soluble sugar (62.7%), and decrease the content of MAD (malondialdehyde) by 24.05%, thus enhancing the resilience of wheat seedlings. The contents of total nitrogen, total potassium, and total phosphorus, as well as quick-acting potassium, quick-acting phosphorus, and alkaline dissolved nitrogen in the soils of the treatment groups are significantly increased by the addition of microorganisms. The soil fertility enhancement also increases the enzyme activities of the soil. The results show that PKN-VR has considerable potential in saline soil remediation, realizes the resource utilization of vinegar residue waste, and provides a new management method for the green development of agriculture.

“…The permanent and long term use of synthetic agro-chemicals is also a major source of diseases in humans and animals because they pollute groundwater reserves by leaching through the root zone [8]. However, organic materials have the capacity to enhance and sustain the soil fertility status on long term basis as they contain a sustained amount of plant macro and micro nutrients [9,10]. Hence, farmers are getting a keen interest in soil amendments of natural fertilizers like poultry manure and phosphorus solubilizing bacteria (PSB) to sustain soil health for improving crop production [11, 8; [12].…”

Sustainable agricultural productivity is under threat due to lack of interest in the use of bio-organic fertilizers to alleviate drawbacks of conventional agricultural practices. Phosphorus solubilizing bacteria plays vital role in improving phosphorus availability to plants through slowly release from inorganic and organic soil phosphorus budgets by solubilization and mineralization. Furthermore, phosphorus solubilizing bacteria in combination with poultry manure has great potential to improve phosphorus uptake, growth and development of the plants. Firstly, a pot experiment consisted of seven strains of phosphorus solubilizing bacteria (PSB) with one control (un-inoculated) were used using completely randomized design (CRD) for 55 days screening trial to screen out the efficient phosphorus solubilizing bacterial strains. Secondly, a field experiment was performed in a randomized complete block design (RCBD) at Research Farm of College of Agriculture, Bahauddin Zakariya University, Bahadur Sub Campus Layyah, South Punjab-Pakistan during 2019-2020 to explore the effect of screened efficient phosphorus solubilizing bacterial strains; PSB0=No inoculation; PSB2=Bacillus spp. PSB2, PSB3=Bacillus spp. PSB3, PSB5=Bacillus spp. PSB5, PSB6=Bacillus spp. PSB6 in combination with poultry manure; PM0= without poultry manure and PM1= with poultry manure (20 t ha-1) on growth and yield traits of sugarbeet, and rhizosphere soil health indicators. Results regarding pot experiment showed that phosphorus solubilizing bacterial strains PSB2, PSB3, PSB5 and PSB6 had great potential to improve growth traits of sugarbeet crop and screened as efficient phosphorus solubilizing bacterial strains. Results of field experiment revealed that the combined application of efficient phosphorus solubilizing bacterial strains (PSB2 and PSB5) with poultry manure (20 t ha-1) produced the highest growth, and yield traits of sugarbeet crop, and rhizosphere soil health indicators.Our findings suggest that the combined application of efficient phosphorus solubilizing bacterial strains (PSB2 and PSB5) with poultry manure (20 t ha-1) is a promising and viable option to achieve the maximum sugarbeet productivity under changing environmental scenarios.
