Most of the vegetable crops are known to depend upon arbuscular mycorrhizal fungal (AM) symbiosis for growth and development, since AM fungi provide nutrients and water in exchange for photosynthates.  The influences of AM fungi (Glomus intraradices (G) and Acaulospora laevis (A)) with Trichoderma viride (T) and Pseudomonas fluorescens (P) alone and in combinations on growth, mycorrhization, chlorophyll content, nutrient uptakes, and yield of broccoli plants were studied in pot culture under glasshouse conditions. The obtained results demonstrated that the single inoculation of broccoli plants with T. viride significantly increased the above ground fresh weight, root length, chlorophyll b, head diameter, root phosphorus, and shoot nitrogen in comparison to uninoculated control plants. On the other hand, consortium of G+A+T+P significantly increased plant height, above ground dry weight, root fresh weight, chlorophyll a, head fresh weight, and root nitrogen content. Similarly, G+T showed maximum leaf area, and P alone showed maximum uptake of shoot phosphorus. Whereas when P was supplied along with T, early flowering was recorded. AM fungal colonisation was negligible and only root tips were found infected in G or A treated plants which confirms low dependency of broccoli on AM fungi.

Although arbuscular mycorrhizal (AM) fungi are known to promote growth and yield of agricultural crops, inoculation methods for effective scaling up from greenhouse to the field are still underexplored. The application of single or mixed beneficial AM fungal isolates is hindered by the lack of experimental reproducibility of findings at different scales and the cost-effectivity of inoculation methods. Seed coating has been considered a feasible delivery system of AM fungal inocula for agricultural crops. In this study, the impact of single and multiple AM fungal isolates applied via seed coating on chickpea productivity was evaluated under greenhouse and field conditions. Overall, plants inoculated with multiple AM fungal isolates had better performance than those inoculated with single AM isolate under greenhouse and field conditions. While plants in greenhouse displayed higher shoot dry weight (14%) and seed individual weight (21%), in field, inoculation with multiple AM isolates increased pod (160%), and seed (148%) numbers, and grain yield (140%). Under field conditions, mycorrhizal root colonization was significantly higher in chickpea plants inoculated with multiple AM fungal isolates compared to other treatments. These findings highlight the potential of field-inoculation with multiple AM fungal isolates via seed coating as a sustainable agricultural practice for chickpea production.

Field experiment was conducted using randomized complete block design with three replicates to evaluate the effect of biofertilizer of Pseudomonas putida and Pseudomonas fluorescens seperatally or together with peatmoss or bentonite as carriers in interaction with four mineral fertilizer levels  zero, 25%, 50%, and 75% of the recommended level on the growth and yield of wheat (Alrasheed varity). Tow control treatments were used, the first included no addition of biofertilizer and  mineral fertilizer and the second included the addition of the recommended level (100%) of mineral fertilizer. The highest value of grain yield was achieved with the treatment of mixed bacterial isolates with an increment mineral fertilizer which to 5.75 Mgha-1 which increased 41.7% compared to first control treatment and 0.9% over the second control treatment. The highest biological yield was achieved mixed bacterial culture  with bentonite and 75% of  the recommended level of mineral fertilizer giving 16.20 Mgha-1 with an increment of 18.8% compared to first control treatment and 11.2% over the second control treatment. The weight of 1000 grain was 47.43g which increased by 21% over the first control treatment and7.4% over the second control treatment with the treatment that include the addition of  Pseudomonas  fluorescens with bentonite and 50% of the recommended level of mineral fertilizer.

The specific objectives of this study were 1 ) knowing certain types of organic fertilizers on the growth of shallots 2 ) knowing the concentrations of Pseudomonas fluorescenss certain the growth of shallots, 3 ) knowing the types of organic fertilizers and the concentrations Pseudomonas fluorescens specificity increase the optimal yield of shallots. To achieve this goal, this research was conducted using factorial experiments with a split Plot Design with 10 treatments and 3 replications. So that there are 10 treatment combinations of a total number of 30 experimental plots. There were 2 factors that were tried, namely the first factor of Organic Fertilizer as the main plot, namely: cow manure 10 ton ha-1 (K1), chicken manure 10 ton ha-1 (K2). While the second factor as the subplot is the concentration of Pseudomonas fluorescens: Watering with water (as a control) 100 ml (P0), Watering with a concentration of Pseudomonas fluorescens 5 ml + normal water 95 ml (P1), Watering with a concentration of Pseudomonas fluorescens 10 + ordinary water 90 ml (P2), sprinkling with a concentration of Pseudomonas fluorescens 15 ml + 85 ml plain water (P3), Flushing with a concentration of Pseudomonas fluorescens 20 + ordinary water 80 ml (P4). The shallot cultivar of Sabu Raijua which was given organic fertilizer of 10 tonnes of chicken manure. Ha-1 and a concentration of Pseudomonas fluorescens 20 + 80 ml of plain water gave the highest growth component at the age of 10 WAP, namely at the age of 10 WAP, namely plant height (37.667cm). Leaves (34, 800 trees), number of tillers (10, 533 trees). The results of shallot bulbs of Sabu Raijua cultivar from organic fertilizer treatment of 10 ton ha-chicken manure1s with a concentration of Pseudomonas fluorescens 20 ml + 80 ml water resulted in components, namely tuber weight per plot (276.70 g ), number of tubers per plot (291, 70 tubers ).

The aim of the research was to examine the effect of rhizospheric bacteria Azotobacter chroococcum, Pseudomonas fluorescens (strains 1 and 2) and Bacillus subtilis on the growth and yield of onion and on the microorganisms in the rhizosphere of onion. The ability of microorganisms to produce indole-acetic acid (IAA), siderophores and to solubilize tricalcium phosphate (TCP) was also assessed. The experiment was conducted in field conditions, in chernozem type of soil. Bacillus subtilis was the best producer of IAA, whereas Pseudomonas fluorescens strains were better at producing siderophores and solubilizing phosphates. The longest seedling was observed with the application of Azotobacter chroococcum. The height of the plants sixty days after sowing was greater in all the inoculated variants than in the control. The highest onion yield was observed in Bacillus subtilis and Azotobacter chroococcum variants. The total number of bacteria and the number of Azotobacter chroococcum were larger in all the inoculated variants then in the control. The number of fungi decreased in most of the inoculated variants, whereas the number of actinomycetes decreased or remained the same.
