“…The biometric characteristics were evaluated based on the isolated effects of arbuscular mycorrhizal fungi (AMF) and phosphorus (P). This trend aligns with the findings of Bassan et al (2018), who similarly did not observe an interaction between P doses and mycorrhizal fungi on the growth of P. dubium seedlings (p<0.05), indicating only isolated effects. Conversely, different results were obtained in the development of Schizolobium amazonicum seedlings concerning P doses associated with AMF species, with Brito et al (2017) observing a positive interaction between these factors.…”

“…It was observed that C. etunicatum and MIX exhibited minimal symbiotic efficiency, while G. albida displayed the best symbiotic efficiency. In a study by Bassan et al (2018) involving the inoculation of mycorrhizal fungi and phosphorus doses, P. dubium seedlings exhibited high dependence and mycorrhizal efficiency for the species G. albida and C. etunicatum, while symbiosis with G. clarum and G. margarita was ineffective.…”

Studies have underscored a growingdemand for innovative practices in the cultivation of seedlings from forest species, with a notable emphasis on the utilization of organic waste, inoculation with arbuscular mycorrhizal fungi (AMF), and phosphate fertilization. This study aimed to evaluate the impact of organic residues, inoculation with AMF, and phosphorus on the growth and quality of Peltophorum dubium (Spreng.) Taub. seedlings. Two independent experiments were conducted. In Experiment I, treatments included inoculation with various AMF species: control (without inoculation), Clareoideoglomus etunicatum, Rhizophagus heterosporum, Rhizophagus clarum, and MIX (a combination of the three AMF species), all in conjunction with varying doses of phosphorus (0, 60, 120, 180, and 240 mg kg-1 soil). In Experiment II, treatments comprised a control group (without AMF) and inoculation with Glomus clarum, Gigaspora margarita, Gigaspora albida, Clareoideoglomus etunicatum, and MIX (a combination of the four AMF species), each associated with four substrates: S1) soil + coarse sand – SCS, S2) SCS + poultry manure, S3) SCS + cattle manure, and S4) SCS + sheep manure. Peltophorum dubium seedlings exhibited heightened growth with the inoculation of R. heterosporum, R. clarum, and MIX. Positive responses were observed in seedlings when exposed to organic residues, particularly sheep manure, resulting in increased biomass production and enhanced Dickson quality index. The AMF inoculation, specifically with R. heterosporum, R. clarum, and MIX, provided optimal growth conditions for P. dubium seedlings. Remarkably, the utilization of organic residues, notably substrates with chicken manure and cattle manure, exerted substantial positive effects on both growth and quality of P. dubium seedlings.
