Título: BIOPROSPECÇÃO E POTENCIAL DE MITIGAÇÃO DO DÉFICIT HÍDRICO NA SOJA POR BACTÉRIAS PROMOTORAS DE CRESCIMENTO DE PLANTAS Autor(es): Tavares, Germanna Gouveia Primeiro Orientador: Costa, Alan Carlos Primeiro Membro da Banca: Silva, Adinan Alves da Segundo Membro da Banca: Müller, Caroline Terceiro Membro da Banca: Moura, Jadson Belém de Abstract: Soybean (Glycine max) is one of the most important agricultural commodities for global food supply; however, it frequently experiences yield losses due to environmental stresses, particularly drought. In addition, the crop has high nutritional requirements to achieve productivity levels that meet the growing global demand for food. This study investigated the potential of plant growth–promoting rhizobacteria (PGPR) to mitigate the drought effects in G. max and to enhance plant development. Initially, in vitro assays were carried out to identify functional traits of the bacteria, followed by genetic characterization. Based on this screening, 11 bacterial isolates, identified as belonging to the genus Bradyrhizobium spp., were selected according to the evaluated functional traits. Subsequently, two greenhouse experiments were carried out to simulate field conditions. The first experiment aimed to select bacteria with the greatest potential to promote the growth of inoculated plants, while the second evaluated the ability of these bacteria to enhance plant tolerance to water deficit. In both experiments, gas exchange, chlorophyll a fluorescence, photosynthetic pigments, and plant growth were assessed under well-watered and water-stress conditions, with and without inoculation using native or commercial bacteria, in addition to morphological evaluations of shoot and root systems. The results indicated that plant growth–promoting bacterial strains improved photosynthetic rates, electron transport efficiency, and root growth under both well-watered and drought stress conditions.

Título: CONECTIVIDADE RURAL E AGRICULTURA FAMILIAR: AVALIAÇÃO DA COBERTURA MÓVEL NO MUNICÍPIO DE RIO VERDE - GOIÁS Autor(es): Oliveira, Márcio da Silva Primeiro Orientador: Silva, Jesiel Souza Abstract: Rural connectivity has a direct impact on the agricultural sector, and its absence represents a structural barrier that limits access to technical, productive, and management information for farming activities. This study emphasizes the relevance of mobile connectivity for fami-ly farming, analyzing how network coverage influences the integrated management of rural properties. The main objective is to evaluate the effects of mobile signal coverage on the management of family farming units in Rio Verde (GO), comparing areas with and without coverage. The research was conducted through bibliographic review, documentary analysis, and primary data collection with farmers, using both quantitative and qualitative approaches to broaden the understanding of the results. Findings reveal that, despite low income, limited mechanization, and restricted participation in public policies, farmers show high smartphone usage and strong awareness of the importance of connectivity for education, financial ser-vices, commercialization, and cooperation among producers. The study highlights the main challenges and opportunities for family farming in the context of digital transformation, showing that access to reliable internet can strengthen competitiveness, increase production efficiency, and reduce rural-to-urban migration. Connectivity, by enabling access to real-time weather forecasts, input prices, and market channels, becomes indispensable for the sustainability of family farming and for improving living conditions in rural áreas.

Título: PARÂMETROS NUTRICIONAIS DA CANA-DE-AÇÚCAR CULTIVADA COM CARBONATITO FOSFÁTICO E MICRORGANISMOS BIOSSOLUBILIZADORES DE FÓSFORO Autor(es): Lemes, Breno Caires Candido Pereira Primeiro Orientador: Valicheski, Romano Roberto Abstract: Brazil's dependence on imported fertilizers and the low availability of phosphorus in tropi-cal soils intensify the search for sustainable alternatives for crop nutrition. The objective was to evaluate the nutritional status of sugarcane subjected to different phosphorus sources associated with biosolubilizing microorganisms. The experiment was carried out in a green-house, in a randomized block design with four replications. Three phosphorus sources were evaluated (phosphate carbonatite rock powder, single superphosphate, and a combination of both) associated with inoculation/co-inoculation of Bacillus spp., Cladosporium cladospori-oides, and Trichoderma harzianum. Ninety-five days after planting, foliar macro- and mi-cronutrient levels were determined. The results showed that the use of the remineralizer provided phosphorus levels like soluble fertilizer, in addition to contributing to potassium supply. The combination of sources favored an increase in zinc. Regarding microorganisms, Trichoderma harzianum stood out by promoting increases in phosphorus, sulfur, and micro-nutrients, regardless of the source used, while Bacillus spp. and Cladosporium cladospori-oides showed greater efficiency when associated with poorly soluble sources. It is concluded that the use of remineralizers associated with biosolubilizing microorganisms constitutes a promising strategy to increase the nutritional efficiency of sugarcane, reduce dependence on imported fertilizers, and promote sustainable production systems.

Título: PLATAFORMA VIRTUAL DE MATURIDADE TECNOLÓGICA Autor(es): Souza, Tays Abstract: Technological Readiness Levels (TRL’s) are widely used as eligibility criteria in innovation funding calls; however, many organizations—particularly micro and small enterprises—face difficulties in accurately identifying the development stage of their technologies. The absence of accessible, standardized, and reliable instruments for measuring technological maturity undermines the alignment of proposals with funding agencies’ requirements and may limit access to innovation resources. This study proposes and develops a Virtual Technological Maturity Platform, grounded in technological auditing and structured around TRL levels, capable of diagnosing the development stage of technologies, supporting decision-making, and guiding qualified submissions to funding mechanisms. The research is based on a theoretical review of technological auditing, innovation management, and TRL, as well as on the analysis of consolidated technology assessment models employed by renowned institutions. From this framework, a diagnostic instrument composed of parameterized strategic questions was developed and subsequently implemented in a web-based digital platform. As a Technical Technological Product, a digital solution was conceived to automatically identify the TRL of projects, organizations, or solutions, systematizing strategic information and providing guidance regarding compliance with funding calls and programs. The platform contributes to strengthening innovation governance and bridging science, technology, and the market. The adoption of a structured TRL-based technological auditing instrument can enhance organizations’ capacity to understand their technological positioning, improve R&D&I proposals, and increase the likelihood of securing funding. The Virtual Technological Maturity Platform demonstrates potential to strengthen the effectiveness of public innovation policies and evidence-based decision-making. Validation will be conducted across different sectors and organizational sizes, with future developments including integration with funding agencies’ databases, incorporation of new metrics, and continuous improvement through analytical intelligence and learning from real-world use.
