“…Additionally, they have been used as coinoculants with Azospirillum brasilense in maize (Gavilanes et al., 2020) and with a mix of Rhizobium tropici and R. freirei plus A. brasilense in common bean (Horácio et al., 2020). However, other cyanobacteria do not fix N but may contribute to crop growth via similar mechanisms to those of the most commonly known plant growth-promoting bacteria (Singh et al., 2017; Gavilanes et al., 2021).…”

Summary Groundnut plants can obtain N from N2 fixation via symbiosis with rhizobia, and inoculation with selected strains can improve grain yields. We report the results of four field experiments carried out under subtropical conditions to confirm whether microbial inoculants can improve groundnut performance through the effects of single inoculation with Bradyrhizobium arachidis (SEMIA6144), coinoculation with Arthrospira platensis (IPR7059) or Synechocystis sp. (IPR7061), or N fertilization with 100 kg ha-1 N on plant growth, nodulation, N accumulation in tissues, grain protein concentration (GPC), and grain yield. There were no effects of inoculation treatment or N fertilizer on shoot or root dry weight. In clayey soil, coinoculation with B. arachidis and cyanobacteria increased grain productivity by an average of 19% compared to that in the noninoculated control. In this clayey soil with a higher P content, regardless of whether coinoculated with B. arachidis or cyanobacteria or single inoculated, grain productivity was 16% greater on average than that resulting from N fertilizer addition. In conclusion, the success of rhizobial inoculation in groundnuts is dependent on the soil, probably due to P limitation and weather conditions.

“…Microbial interactions in the rhizosphere are intensified by released plant root exudates, which are the main food source for microorganisms, increasing their population density and activity (Raaijmakers et al, 2009;Gavilanes et al, 2021). Plants benefit from root-associated microorganisms through various activities (phytohormones, nutrient supplementation, and pathogen suppression), ultimately increasing growth, health, and yield, thus decreasing the dependence on harmful chemicals and their aftereffects (Raaijmakers et al, 2009;Syed and Tollamadugu, 2019).…”

The shaping of onion seedlings performance through substrate formulation and co-inoculation with beneficial microorganism consortia

IntroductionSmart management in crop cultivation is increasingly supported by application of arbuscular mycorrhizal fungi (AMF) and plant growth-promoting microorganisms (PGPM), which sustain soil fertility and plant performance. The aim of this study was the evaluation of the effects of consortia composed of (Claroideoglomus claroideum BEG96, Claroideoglomus etunicatum BEG92, Funneliformis geosporum BEG199, Funneliformis mosseae BEG 95, and Rhizophagus irregularis BEG140) and PGPM (Azospirillum brasilense – AZ, or Saccharothrix sp. – S) on onion cultivated in growing media with a composition corresponding to a degraded soil. MethodsThree types of substrate formulations were used, with peat:sand ratios of 50:50, 70:30, 100:0 (v:v). The analysis of substrate parameters crucial for its fertility (pH, salinity, sorption complex capacity, and elements’ content) and characteristics reflecting onion seedlings’ performance (fresh weight, stress biomarkers, and elements’ content) was performed. ResultsAMF colonized onion roots in all treatments, showing increasing potential to form intercellular structures in the substrates rich in organic matter. Additionally, co-inoculation with PGPM microorganisms accelerated arbuscular mycorrhiza establishment. Increased antioxidant activity and glutathione peroxidase (GPOX) activity of onion roots sampled from the formulations composed of peat and sand in the ratio of 100:0, inoculated with AMF+S, and positive correlation between GPOX, fresh weight and antioxidant activity of onion roots reflected the successful induction of plant acclimatization response. Total phenols content was the highest in roots and leaves of onion grown in substrates with 70:30 peat:sand ratio, and, in the case of roots, it was correlated with AMF colonization parameters but not with antioxidant activity.DiscussionAMF and PGPM efficiency in supporting onion growth should be linked to the increased onion root system capacity in mineral salts absorption, resulting in more efficient aboveground biomass production. AMF and PGPM consortia were effective in releasing minerals to soluble fraction in substrates rich in organic matter, making elements available for uptake by onion root system, though this phenomenon depended on the PGPM species. Microorganism consortia enhanced onion seedlings’ performance also in substrates with lower content of organic carbon through plant biofertilization and phytostimulation

Groundnut can obtain N from the N2 fixation in the symbiosis with rhizobia and inoculation with selected strains can improve grain yields. We report the results from four field experiments, aiming to verify if microbial inoculants may improve groundnut performance, through the effects of single inoculation with Bradyrhizobium sp. (SEMIA6144), of co-inoculation Arthrospira platensis IPR7059 or Synechocystis sp. IPR7061, and of the N fertilization with 100 kg ha− 1 of N on plant growth, nodulation, N accumulated in tissues, grain protein, and grain yield. There were no effects of inoculation treatments and N-fertilizer on shoot and root dry weights. In clayey soil, co-inoculation with Bradyrhizobium sp. and cyanobacteria increased grain productivity by an average of 19% compared to the non-inoculated control. In this clayey soil with higher P content, regardless of whether co-inoculated with Bradyrhizobium sp. and cyanobacteria or single inoculated, grain productivity was 16% higher on average compared to nitrogen fertilizer. In conclusion, it was clear that success of rhizobia inoculation in groundnut is dependent on the soil, probably due to P limitation, and weather conditions.
