“…The quantity and distribution of branches determine the canopy architecture, which influences light interception, lodging resistance, and seed production (Yang et al., 2021). In our study, positive results were observed, with the co‐inoculation of T. asperellum showing an 18% increase in branch number compared to that with the standard inoculation with Bradyrhizobium spp.…”

Co‐inoculation of soybean with plant growth‐promoting microorganisms has the potential to increase yield, and the Amazon is a biome rich in these beneficial microorganisms. Soybean is the most important grain crop in Brazil and is highly benefited by inoculation with Bradyrhizobium spp. strains, both of which represent exotic symbiotic partners. The objective of this study was to evaluate the effects of soybean co‐inoculation with Amazonian strains of Trichoderma asperellum and Bacillus amyloliquefaciens. Greenhouse and field experiments were conducted during the 2020 and 2021 crop seasons in Brazil, respectively. The experimental design was completely randomized in the greenhouse, and randomized blocks were used in the field, both with 3 × 2 factorial schemes. Standard inoculation with Bradyrhizobium and co‐inoculation with T. asperellum and B. amyloliquefaciens was considered the first factor, and the second factor was represented by phosphate fertilization (0 and 100 kg ha−1 of P2O5). The root system volumes were 25% and 17% higher than those of the standard inoculation with T. asperellum and B. amyloliquefaciens, respectively. In 2020, co‐inoculation with T. asperellum increased yield by 15%, plant height by 27%, and net profit by up to 121 USD compared with standard inoculation. In 2021, co‐inoculation with T. asperellum and B. amyloliquefaciens resulted in increases in several growth parameters compared to those with standard inoculation, including 7% and 13% greater yields, and 159 USD and 309 USD increases in net profit, respectively. Our results indicate the possibility of expanding soybean co‐inoculation with local strains of Bacillus and Trichoderma, with benefits for productivity and profitability.

“…Genetic analysis of SD revealed that SD was controlled by a batch of different QTLs. Using 257 soybean accessions, generalized linear model (GLM) and enriched compressed mixed linear model (E-cMLM) revealed that satt382 (A1) and satt534 (B2) with the highest positive and negative additive effects, respectively, were associated with SD (Yang, 2011). Five SD-associated QTLs (qSD-1-1, qSD-8-1, qSD-8-2, qSD-24-1, and qSD-24-2), located on the A2, C2, and L linkage groups, with phenotypic variance explained by 8.7-17.0%, were identified using composite interval mapping (CIM) based on 165 materials from the soy01 population (Zhou et al, 2009).…”

IntroductionSoybean stem diameter (SD) and branch diameter (BD) are closely related traits, and genetic clarification of SD and BD is crucial for soybean breeding.MethodsSD and BD were genetically analyzed by a population of 363 RIL derived from the cross between Zhongdou41 (ZD41) and ZYD02878 using restricted two-stage multi-locus genome-wide association, inclusive composite interval mapping, and three-variance component multi-locus random SNP effect mixed linear modeling. Then candidate genes of major QTLs were selected and genetic selection model of SD and BD were constructed respectively.Results and discussionThe results showed that SD and BD were significantly correlated (r = 0.74, P < 0.001). A total of 93 and 84 unique quantitative trait loci (QTL) were detected for SD and BD, respectively by three different methods. There were two and ten major QTLs for SD and BD, respectively, with phenotypic variance explained (PVE) by more than 10%. Within these loci, seven genes involved in the regulation of phytohormones (IAA and GA) and cell proliferation and showing extensive expression of shoot apical meristematic genes were selected as candidate genes. Genomic selection (GS) analysis showed that the trait-associated markers identified in this study reached 0.47-0.73 in terms of prediction accuracy, which was enhanced by 6.56-23.69% compared with genome-wide markers. These results clarify the genetic basis of SD and BD, which laid solid foundation in regulation gene cloning, and GS models constructed could be potentially applied in future breeding programs.

“…Thus, currently, the great challenge of the farmers is to increase the productivity of soybean. One of the alternatives found is the use of plant regulators (such as herbicides applied in subdoses) (Silva et al, 2009) in order to stop the growth in plant height and to induce lateral branches, which might lead to a greater formation of reproductive nodes and, consequently, more flowers and pods per plant (Yang et al, 2021). Plant growth regulators are synthetic chemicals with an effect on plant metabolism, so they inhibit, alter, or promote physiological and biochemical processes in plants (Nagashima et al, 2010;Silva et al, 2012).…”

The use of growth regulators through the herbicide subdoses is a promising alternative capable of reducing the size of plants, making them more compact and photosynthetically more active and efficient. The objective was to evaluate the effect of herbicide application on the development and production components of six soybean cultivars. The experiment was conducted in field under randomized blocks with four replications. Six soybean cultivars (M8644 IPRO, M8372 IPRO, M8349 IPRO and M8766 RR, NS7901 RR and CD251 RR) were submitted the application of three herbicides and their respective subdoses (2,4-D - 40.3 g ha-1; Imazetapir - 26.5 g ha-1 and Lactofen - 96 g ha-1). An additional treatment without the application of any herbicide was also evaluated (Control treatment). Subdoses of 2,4-D, Lactofen and Imazetapyr provided greater plant height, height of insertion of the first pod, branches per plant, number of pods and number of grains. A new adequacy in the doses of 2,4-D, Lactofen and Imazetapyr is necessary to contribute in the future to increase the productivity of soybean.
