Growth Promoting

The continuity of traditional planting systems in the last few decades has encountered its most significant challenge in the harsh changes in the global climate, leading to frustration in the plant growth and productivity, especially in the arid and semi-arid regions cultivated with moderate or sensitive crops to abiotic stresses. Faba bean, like most legume crops, is considered a moderately sensitive crop to saline soil and/or saline water. In this connection, a field experiment was conducted during the successive winter seasons 2018/2019 and 2019/2020 in a salt-affected soil to explore the combined effects of plant growth-promoting rhizobacteria (PGPR) and potassium (K) silicate on maintaining the soil quality, performance, and productivity of faba bean plants irrigated with either fresh water or saline water. Our findings indicated that the coupled use of PGPR and K silicate under the saline water irrigation treatment had the capability to reduce the levels of exchangeable sodium percentage (ESP) in the soil and to promote the activity of some soil enzymes (urease and dehydrogenase), which recorded nearly non-significant differences compared with fresh water (control) treatment, leading to reinstating the soil quality. Consequently, under salinity stress, the combined application motivated the faba bean vegetative growth, e.g., root length and nodulation, which reinstated the K+/Na+ ions homeostasis, leading to the lessening or equalizing of the activity level of enzymatic antioxidants (CAT, POD, and SOD) compared with the controls of both saline water and fresh water treatments, respectively. Although the irrigation with saline water significantly increased the osmolytes concentration (free amino acids and proline) in faba bean plants compared with fresh water treatment, application of PGPR or K-silicate notably reduced the osmolyte levels below the control treatment, either under stress or non-stress conditions. On the contrary, the concentrations of soluble assimilates (total soluble proteins and total soluble sugars) recorded pronounced increases under tested treatments, which enriched the plant growth, the nutrients (N, P, and K) uptake and translocation to the sink organs, which lastly improved the yield attributes (number of pods plant−1, number of seeds pod−1, 100-seed weight). It was concluded that the combined application of PGPR and K-silicate is considered a profitable strategy that is able to alleviate the harmful impact of salt stress alongside increasing plant growth and productivity.

The Impact

Intercropping is a farming practice that fights pests and diseases and improves plant growth. The use of plant growth-promoting rhizobacteria (PGPR) strains to boost the yield of intercrops constitutes a promising tool in agricultural practice. This study investigated the impact of single inoculation and co-inoculation with PGPR on plant biomass and phosphorus (P) and nitrogen (N) concentrations under different cropping systems. Two PGPR strains with different traits were selected: PGP13 (Rahnella aquatilis) and PS11 (Pseudomonas sp.). A greenhouse experiment was designed using durum wheat (Triticum durum L.) and faba bean (Vicia faba L.), sole cropped or intercropped, including four inoculation treatments: (i) uninoculated, (ii) inoculated with PS11 (iii) inoculated with PGP13, and (iv) co-inoculated with PS11 + PGP13. Co-inoculation under the intercropping system improved plant dry matter and enhanced bean pod and wheat spike weights to 685.83% and 385.83%, respectively, of the values for uninoculated, intercropped plants. Higher P and N concentrations were detected in intercropped, co-inoculated plants and in bean pods and wheat spikes. The results were then submitted to principal component analysis, showing that treatments with higher biomass and nutrient concentrations were strongly correlated with intercropped, co-inoculated plants.

Fusarium Chlamydosporum

The objective of this study was to evaluation the efficiency of  Arbuscular mycorrhizal fungi and some species of  Plant growth promoting rhizobacteria (PGPR) to control Fusarium chlamydosporum fungus causing agent of decline date palm off-shoots. The isolation and identification results  showed presence of F. chlamydosporum fungus from infected roots of infected palm trees and its major causing agent of diseases. The results  appeared  Pseudomonas fluorescens , Azotobacter chroococcum and Azosperillium sp. have high antagonism of pathogen under laboratory conditions. The evaluation results of  biocontrol factors Glomus  intraradices, G. mosseae, Gigaspora,  P. fluorescens, A. chroococcum and Azospirillum sp.  indicated that all treatments caused significant reduction in disease  severity of death palm off-shoots disease into13.3-60.0%. compared to control (pathogen only) 86.7%. The interaction between G. intraradices and  P. flourescens  caused significant reduction in disease severity to 13.3% and enhanced the growth of foliage and root of offshoots length to 39.0 and 36.3cm respectively and increased the fresh and dry weight of  foliage and root, 1.7750, 0.4977, 1.764 and  0.339g  this result was closed to Beltanol fungicide effect. Also all biocontrol agents which used in this study alone (without pathogen) enhancement of plant growth  compared with control treatment. The results of the current study showed for the first time that Arbuscular mycorrhizal fungi and Azospirillum sp. Bactrium to control and have good inhibition of Fusarium chlamydosporum fungus causing agent of decline date palm off-shoots and increasing plant growth in Iraq.
