Phosphorus (P) is one of the essential macronutrients for plant growth, being a highly required resource to improve productive performance several crops, especially in weathered soils. However, large part nutrients applied form fertilizers becomes “inert” medium term and cannot be assimilated by plants. Rationalizing use phosphorus matter extreme importance environmental sustainability socioeconomic development. Therefore, alternatives management this nutrient are needed, P-solubilizing microorganisms an option optimize its allowing exploration less available fractions soils reducing demand phosphate fertilizers. The objective study discuss how can intermediate sustainable agriculture. In review study, we present studies about role as mobilizers soil. We describe plants main problems related unsustainable exploitation natural reserves chemical Mainly highlight constitute fundamental release inert portion nutrient, where mechanisms solubilization mineralization. also discussed benefits that inoculation provides crops well practices using them bioinoculants. inoculants viable future agriculture, mainly because application significantly reduce P and, consequently, reserves. addition, new research must conducted development technologies, prospecting biological products, improvement allow higher efficiency

Synergistic interactions of nanoparticles and plant growth promoting rhizobacteria enhancing soil-plant systems: a multigenerational perspective

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: April 29, 2024

Sustainable food security and safety are major concerns on a global scale, especially in developed nations. Adverse agroclimatic conditions affect the largest agricultural-producing areas, which reduces production of crops. Achieving sustainable is challenging because several factors, such as soil flooding/waterlogging, ultraviolet (UV) rays, acidic/sodic soil, hazardous ions, low high temperatures, nutritional imbalances. Plant growth-promoting rhizobacteria (PGPR) widely employed in-vitro they recognized more environmentally sustainably friendly approach to increasing crop yield contaminated fertile soil. Conversely, use nanoparticles (NPs) an amendment has recently been proposed economical way enhance texture improving agricultural yields. Nowadays, various research experiments have combined or individually applied with PGPR NPs for balancing elements response control adverse situations, expectation that both additives might perform well together. According findings, interactive applications significantly increase yields than alone. The present review summarized functional mechanistic basis role NPs. However, this article focused potential direction realize possible interaction at large scale upcoming years.

Corn Yield and Phosphorus Use Efficiency Response to Phosphorus Rates Associated With Plant Growth Promoting Bacteria

Frontiers in Environmental Science, Journal Year: 2020, Volume and Issue: 8

Published: April 7, 2020

The use of plant growth promoting bacteria that can solubilize phosphorus (P) has shown potential to improve nutrient availability in grass crops such as corn (Zea mays L.) This study was developed investigate if inoculation with Azospirillum brasilense, Bacillus subtilis or Pseudomonas fluorescens associated P2O5 rates efficiency (PUE) reflecting on greater development and yield. field trial set up a Rhodic Hapludox under no-till system Savannah conditions, completely randomized block design four replicates. Treatments were tested full factorial included: i) five (0 105 kg ha-1) ii) PGPB seed (Control – without inoculation, A. B. P. fluorescens). Inoculation found increase grain yield by 17.5% when inoculated 70 ha-1 34.7% brasilense application ha-1. In addition, biomass P uptake, number grains per row, stem diameter, ear length PUE. results this showed positive improvements uptake result an 86.9 40.6% PUE, respectively; while the less evident. Further research should be conducted biotic or/and abiotic conditions better understand role PGPB, alone combination co-inoculated method.

Inoculation with Plant Growth-Promoting Bacteria to Reduce Phosphate Fertilization Requirement and Enhance Technological Quality and Yield of Sugarcane

Microorganisms, Journal Year: 2022, Volume and Issue: 10(1), P. 192 - 192

Published: Jan. 17, 2022

Phosphorus (P) is a critical nutrient for high sugarcane yields throughout its cultivation cycles, however, higher amount of P becomes rapidly unavailable to plants due adsorption soil colloids. Some plant growth-promoting bacteria (PGPBs) may be able enhance availability and produce phytohormones that contribute crop development, quality, yield. Thus, this study aimed evaluate leaf concentrations nitrogen (N) P, yield, technological quality as function different levels phosphate fertilization associated with inoculation PGPBs. The experiment was carried out at Ilha Solteira, São Paulo-Brazil. experimental design randomized blocks three replications, consisting five phosphorus rates (0, 25, 50, 75, 100% the recommended P2O5 rate) eight inoculations, involving species PGPBs (Azospirillum brasilense, Bacillus subtilis, Pseudomonas fluorescens) which were applied combined or in single application into planting furrow RB92579 variety. B. subtilis P. fluorescens provided concentration sugarcane. alter variables stalk yield excess lack fertilizer harmful cultivation, regardless use bacteria. We recommend A. brasilense + 45 kg ha-1 aiming greater This treatment also increases sugar resulting savings 75% rate, thus being more efficient sustainable alternative reducing production costs.

Identification of the Phosphorus-Solubilizing Bacteria Strain JP233 and Its Effects on Soil Phosphorus Leaching Loss and Crop Growth

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: April 29, 2022

Phosphorus (P) is one of the most limiting nutrients in global agricultural ecosystems, and phosphorus-solubilizing bacteria (PSB) can convert insoluble P into soluble P, thereby improving absorption use soil by plants. Increasing leaching loss due to PSB that could lead water eutrophication a major concern, although no direct experimental evidence available evaluate these effects. In this study, highly efficient strain, Pseudomonas sp. JP233, was isolated from its P-solubilizing agent identified metabolomics HPLC analyses. The effects JP233 on contents leachates were also analyzed microcosm experiments absence presence maize. solubilize forms, molybdate reactive phosphorus (MRP) content reached 258.07 mg/L NBRIP medium containing 5 g/L Ca3(PO4)2 within 48 h. Metabolomics analysis demonstrated organic acid involved solubilization primarily 2-keto gluconic (2KGA). Further, revealed 2KGA rapidly accumulated 19.33 mg/mL Microcosm showed MRP total (TP) solutions not significantly higher after inoculation. However, inoculation with maize plant soils decreased TP days 14 (P < 0.01), 21 28 0.05). Inoculation strain increased biomass aerial components whole plants Thus, exhibited significant plant-growth-promoting effect development. conclusion, application does increase leachate loss. Rather, help reduce loss, while promoting P.

Plant growth-promoting bacteria are one of the most interesting methods controlling fungal phytopathogens. These can participate in biocontrol via a variety mechanisms including lipopeptide production, hydrolytic enzymes (e.g., chitinase, cellulases, glucanase) microbial volatile organic compounds (mVOCs) and induced systemic resistance (ISR) triggering. Among bacterial genera frequently studied this aspect Bacillus spp. pumilus . Due to range traits, B. is members that be used So far, number strains exhibit properties against phytopathogens have been described, e.g., HR10, PTB180, SS-10.7, MCB-7, INR7, SE52, SE34, SE49, RST25, JK-SX001, KUDC1732. capable suppressing such as Arthrobotrys conoides , Fusarium solani oxysporum Sclerotinia sclerotiorum Rhizoctonia Fagopyrum esculentum Importantly, promote plant growth regardless whether it alters native microbiota or not. However, order increase its efficacy, research still needed clarify relationship between Despite that, already concluded good candidates environmentally friendly commercially effective agents.
