Autor(es): Andrade, Antônio Nunes de Orientador: Dias, Thiago Jardelino Abstract: Water is one of the most important elements for the development of vegetables, including sweet potato (Ipomoea batatas L.), an herbaceous dicotyledonous plant with an edible tuberous root rich in fiber, carbohydrates, vitamins, proteins and sugars. Thus, the objective of this study was to select sweet potato genotypes tolerant to water deficit. For this, nine genotypes were used (Brazlândia Branca, FSC-FW-42, UFSCLW- 102, UFSC-LO-66, UFSC-LP-46, UFSC-FP-40, UFSC-LP-115, UFSC-FP-39, UFSC-LP-75).The plants were subjected to two water levels: irrigation with 80% of the substrate retention capacity (control, well-irrigated), and total water restriction between 30 and 51 days after planting (DAP), and harvested at 120 DAP. The experiment was carried out in a greenhouse located in the experimental area of the Seedling Production Laboratory, belonging to the Center for Human, Social and Agrarian Sciences of the Federal University of Paraíba (CCHSA/UFPB), in Bananeiras, Paraíba, Brazil. The experimental design was completely randomized, in a 2 × 9 factorial scheme (water conditions × genotypes), with 6 replicates. Wilting symptoms, biomass production, gas exchange, chlorophyll index, chlorophyll fluorescence, relative water content and electrolyte leakage were evaluated. Water deficit caused oxidative stress, increasing electrolyte leakage and reducing growth and productivity in all genotypes evaluated. The genotypes UFSC-FW-42, UFSC-LW-102 e UFSC-LP-115 were those that presented the highest productivity under water deficit, and the UFSC-FW-42 and UFSC-LP-115 genotypes also presented lower electrolyte leakage and higher FV/FM, suggesting a greater antioxidant capacity of these genotypes. In this context, the genotypes that presented the greatest tolerance to water deficit were UFSCFW-42 and UFSC-LP-115, which present cream and purple colored pulp, respectively. These results represent an important advance for the continuation of breeding programs with these materials aiming at tolerance to water deficit.

The junior enterprise (EJ) provides undergraduate students with the opportunity to work in business management while simultaneously providing formal professional services. Given this information and the potential local demand for professional support in the agricultural field, specifically in coffee farming, a group of students from the Bachelor's degree in Agroecology at the Federal University of Paraíba, Campus III in Bananeiras, Paraíba, decided to found the program's junior enterprise. The objective of this work was to describe and analyze the history of the founding of the junior enterprise of the Bachelor's degree in Agroecology. The methods used in this process included meetings between students and advisors, meetings with SEBRAE (Brazilian National Support Service for Micro and Small Enterprises), PROEX/UFPB (Office of the Provost for Extension at the Federal University of Paraíba), and Executive Consultoria, the junior enterprise of the Business Administration program on the same university campus. Accounting and legal advice were hired, the bylaws were registered, the election and inauguration were registered, the National Registry of Legal Entities (CNPJ), municipal licenses were obtained, a selection process with a semi-structured interview, and a preselection online questionnaire for the program community about the MEJ program was completed. During this period, three private rural consulting contracts were signed, a service proposal was submitted to a city hall, and bioinput sales were also conducted. The existence of the EJ program and the institution's support with grants are considered extremely important. The EJ program helps to raise awareness of the program and the professional activities of the Bachelor of Agroecology student, as well as personal and professional development.

The present study aims to conduct a floristic survey of the arboreal and shrubby apicultural pasture in an area destined for the implementation of a model apiary at the Center for Human, Social, and Agrarian Sciences (CCHSA/UFPB), located in Bananeiras-PB. The research, conducted between August and December 2024, involved the identification of species in six sample plots, evaluating 331 plant individuals distributed across 21 families and 49 botanical species. The most representative families were Fabaceae, Myrtaceae, Apocynaceae, and Anacardiaceae. The species Talisia esculenta stood out for the highest abundance, followed by Xylopia sericea and Vismia guianensis. The ten most abundant species, corresponding to 61% of the sampled individuals, mainly provide pollen to bees, with 40% of them also offering nectar. The results demonstrate the significant potential of the area for apicultural production, especially for pollen-based products such as propolis and royal jelly, supported by the annual distribution of floral resources. It is concluded that the vegetation surrounding the model apiary presents ecological and productive relevance, and it is necessary to deepen studies on the phenology of the species and plant-bee interactions in order to ensure greater precision in understanding the local api-flora and favor the traceability of apicultural products.

In this context, university extension connects academic knowledge with local wisdom. This study aimed to systematize methodological experiences from extension projects between 2022 and 2025 at UFPB's Campus III, focusing on the training of goat milk producers in Paraíba. The methodology used was Holiday’s experience systematization method, which helped identify relevant learnings through the analysis of project proposals and final reports. The empirical material included institutional documents analyzed using Bardin's thematic content analysis technique. The results reveal a similar methodological pattern with common stages: defining locations and institutional partnerships, prior training of students, field diagnosis, development of teaching materials, and producer training. Challenges were identified in three areas: methodological (lack of continuous evaluation and a database), structural (property and logistical limitations), and relational (dependence on intermediary institutions). Based on these findings, guidelines are proposed for future extension actions, such as continuous evaluation protocols, adaptive schedules, active methodologies, and formalizing the integration of local knowledge. These recommendations, aligned with the principles of popular education and dialogical extension, aim to strengthen extension activities in dairy goat farming in the region.
