The most critical stage in the entire production process is harvesting and processing, where there is the greatest risk of such damage occurring. The objective of this work was to develop a quick and practical methodology for evaluating mechanical damage in soybean seeds. The work was carried out in a factorial design with two 5x6 factors using different concentrations of sodium hypochlorite (4.75, 5.0, 5.25, 5.50 and 5.75%) and soaking times (3, 4, 5, 6, 7 and 10 min). The solutions were prepared from commercial 9% sodium hypochlorite, performing the necessary dilutions using the dilution equation C1V1 = C2V2. This treatment was applied to three soybean cultivars: Olimpo 80I82RSF IPRO, M7601 I2X, and Bônus 8579RSF IPRO, one batch of each, from 2023/2024 growing season, with four replicates of 100 seeds per treatment. For mechanical damage tests, a seed counter and the necessary sodium hypochlorite were used to prepare 1.0 liters of stock solution. The results indicated that, for soybean cultivars Bônus 8579 RSF IPRO and M7601 I2X, among the concentrations evaluated in this study, the 5.75% sodium hypochlorite solution associated with a treatment time of 3 minutes presented the lowest values of mechanical damage. For Olimpo 80I82 RSF IPRO cultivar, it was observed that a 5.75% sodium hypochlorite concentration combined with a 10-minute exposure time resulted in a lower rate of mechanical damage. However, the literature and technical recommendations from Embrapa indicate the use of a 5.25% solution, emphasizing that further research comparing different concentrations in different batches is necessary to validate possible methodological adjustments, since these conditions do not compromise the reliability of the results and allow for greater speed in the evaluation process.

The search for sustainable management practices has become increasingly important in the face of environmental problems and high production costs. Furthermore, the labor lack in the field increases the demand for techniques that facilitate cultivation, reduce costs, and increase productivity. The objective of this study was to evaluate the effect of a biological product and the productive performance of determinate growth habit tomato hybrids for the fresh market. The work was carried out in two experimental areas in the municipality of Morrinhos. A phosphorus-solubilizing inoculant composed of the bacterium Bacillus velezensis UFV3918, associated with organomineral fertilizer, was used. Tomato plants were cultivated at densities of 10,000 plants ha-1 and 20,000 plants ha-1. The data were subjected to statistical analysis, with means compared using Fisher's exact test (LSD ≤ 0.05). Significant differences in productivity were observed in function of hybrids, planting densities, and biological product application. The results indicate that the use of bio-inputs, associated with the cultivation of specific hybrids in a ground-level system, have the potential to increase productivity and reduce costs, constituting a viable alternative for producers who supply the fresh market.

The transformations observed in the traditions and culture of the Calon Roma Community of Lagoa Quente, in Caldas Novas, over the period studied indicate the occurrence of significant changes. These changes appear to be related to the need for cultural continuity within a context marked by discriminatory practices and low social visibility. The objective of this research is to identify evidence of Overculturality in the Calon Roma Community of Lagoa Quente, in Caldas Novas, Goiás, as well as to understand its history and culture, thereby contributing to the valorization of the cultural identity of this ethnic group through the dissemination of an e-book in the form of a literary novel that addresses the historical trajectory and cultural manifestations of the Roma people. This research is qualitative in nature. The methodological procedures include literature review (Mattar, Ramos, 2021), case study (André; Ludke, 2018), life history (Marconi; Lakatos, 2003), oral history (Silva; Santos, 2022), state-of-the-art review (Romanowski; Ens, 2006), and the conversation methodology (Silva, 2024). Data collection will be carried out through interviews and direct observation. Data analysis will employ discourse analysis (Greimas, 1975), the evidentiary paradigm (Ginzburg, 1989), and thematic analysis (Braun; Clarke, 2006). The specific objectives guide the analysis of theoretical frameworks addressing the origin, culture, and Roma identity. The historical trajectory and cultural practices of the Calon Roma Community of Lagoa Quente, located in Caldas Novas, were also investigated. Furthermore, the study sought to discuss the role of education in the valorization of Roma culture and its impact on processes of identity consolidation and social empowerment. The analysis of the case study and the life history of the first Calon Roma individual from the community to enter higher education identified evidence of the Overculturality process and made it possible to understand the individual’s context within the community and the role of education in ethnic survival and empowerment Editor: Instituto Federal Goiano Tipo: Dissertação e Produto Técnico e Educacional Mon, 27 Apr 2026 00:00:00 GMT https://repositorio.ifgoiano.edu.br/handle/prefix/6610 2026-04-27T00:00:00Z https://repositorio.ifgoiano.edu.br/handle/prefix/6609 Título: PRODUÇÃO DE BIOGÁS A PARTIR DE DEJETOS SUÍNOS: EFEITOS SAZONAIS NO RENDIMENTO DE METANO E NO DESEMPENHO DO BIODIGESTOR Autor(es): Silva, Maria das Dores Xavier da Primeiro Orientador: Minafra, Cibele Silva Abstract: This study evaluated the influence of seasonal conditions on the biogas profile generated from swine manure treated in a German-type biodigester. The research was conducted at a finishing pig farm located in the municipality of Rio Verde, Goiás, Brazil, consisting of three production units and totaling approximately 28,000 animals.The residues, composed of feces, urine, feed leftovers, and wash water from the facilities, were subjected to mechanical agitation and subsequently directed to a Continuous Stirred-Tank Reactor (CSTR). The monitoring of biogas production and composition was carried out over a twelve-month period, covering different seasonal conditions, in order to assess the influence of climatic and operational factors on anaerobic digestion efficiency.Measurements were performed three times a day (at 08:00, 11:00, and 16:00) at a fixed point in the pipeline, using a portable digital multigas analyzer capable of quantifying the concentrations of carbon dioxide (CO2), methane (CH4), oxygen (O2), and hydrogen sulfide (H2S).Statistical analyses were conducted in the R environment (R Core Team, 2024), using Pearson correlation, Generalized Additive Models (GAM), and cluster analysis.The results indicated that the observed correlations confirm the influence of oxygen (O2) and temperature on methanogenesis and sulfidogenesis processes. CH4 and CO2 production showed seasonal stability, while O2 and H2S concentrations varied significantly, indicating greater sensitivity to climatic conditions. Cluster analysis demonstrated that more strictly anaerobic environments favor higher methane production.Thus, the integrated monitoring of gases and environmental factors is essential to ensure bioreactor stability, demonstrating that the efficiency of anaerobic digestion depends on the balance between microbiological processes and the adopted operational practices.
