Acúmulo de nutrientes nos frutos e teor foliar de pimenta malagueta (capsicum frutescens) sob diferentes manejos de adubação fosfatada / Accumulation of nutrients in fruits and foliar content of chilly pepper (capsicum frutescens) under different management of phosphate fertilization
O cultivo de pimentas (Capsicum frutescens) tem grande importância para o agronegócio brasileiro. Nos últimos anos vem-se tendo a busca incessante por meio de melhorar a qualidade nutricional das plantas e com isso melhorar a qualidade e produtividade dos frutos. Os fertilizantes de liberação lenta têm se mostrado como uma excelente alternativa em relação a adubação mineral convencional, promovendo melhorias relacionadas a nutrição das plantas. O Fósforo (P) é o nutriente que mais influencia no tamanho dos frutos, crescimento da planta e sistema radicular, o que, consequentemente, pode beneficiar a absorção de outros nutrientes. Desta forma, objetivou-se avaliar a influência de diferentes doses e fontes de adubação fosfatada sobre os teores de macro e micro nutrientes na parte aérea e frutos de pimenta. Realizou-se o experimento em casa de vegetação no campus JK da UFVJM, Diamantina- MG, no delineamento inteiramente casualizado com onze manejos de adubação (ausência de adubação - testemunha, tratamento mineral – Super fosfato simples, tratamento orgânico – Torta de filtro, organomineral peletizado 50% da dose de P2O5, organomineral peletizado 100% da dose de P2O5, organomineral granulado 50% da dose de P2O5, organomineral granulado 100% da dose de P2O5, MAP revestido 50% da dose de P2O5, MAP revestido 100% da dose de P2O5, Formulado triplo 50% da dose de P2O5 e Formulado triplo 100% da dose de P2O5). Foram avaliados os teores de macro e micro nutrientes da parte aérea frutos da pimenta, sendo os macro nutrientes avaliados: Fósforo (P), Potássio (K), Cálcio (Ca), Magnésio (Mg) e os micro nutrientes avaliados: Ferro (Fe), Manganês (Mn), Zinco (Zn). A adubação organomineral se destacou com relação aos teores nutricionais no fruto e folha da pimenta malagueta (Capsicum frutescens), o que provavelmente pode estar relacionado aos benefícios que a adubação mineral com incremento da adubação orgânica apresenta. Em especial tem-se o organomineral granulado 50%, que apresentou resultados expressivos com relação a absorção de macro e micro nutrientes, além da vantagem de poder utilizar metade da dose indicada.
Agronomic characteristics and postharvest quality of strawberry in a semi-hydroponic cultivation system
Abstract The objective of this work was to evaluate the influence of using a semi-hydroponic system on the agronomic and postharvest variables of strawberry cultivars. The experiment was conducted in a randomized complete block design, with cultivars Aromas, Camarosa, Festival, Merced, Oso Grande, and San Andreas, with eight plants per plot and five replicates. Agronomic and postharvest variables were evaluated. Cultivar San Andreas showed the highest values for the agronomic variables number of commercial fruits and total and commercial yield per plant, with the highest yield in October, November, and December. The postharvest variables moisture, firmness, pH, titratable acidity, and reducing sugars did not differ between cultivars. In a semi-hydroponic system, the San Andreas cultivar presents the best results for the agronomic variables related to fruit yield, with the highest yield in October and November
Using active learning strategies during a quality improvement collaborative: exploring educational games to enhance learning among healthcare professionals
Background The Breakthrough Series model uses learning sessions (LS) to promote education, professional development and quality improvement (QI) in healthcare. Staff divergences regarding prior knowledge, previous experience, preferences and motivations make selecting which pedagogic strategies to use in LS a challenge.Aim We aimed to assess new active-learning strategies: two educational games, a card game and an escape room-type game, for training in healthcare-associated infection prevention.Methods This descriptive case study evaluated the performance of educational strategies during a Collaborative to reduce healthcare-associated infections in Brazilian intensive care units (ICUs). A post-intervention survey was voluntarily offered to all participants in LS activities.Results Seven regional 2-day LS were held between October and December 2022 (six for adult ICUs and one for paediatric/neonatal ICUs). Of 194 institutions participating in a nationwide QI initiative, 193 (99.4%) participated in these activities, totalling 850 healthcare professionals. From these, 641 participants responded to the survey (75.4%). The post-intervention survey showed that the participants responded positively to the educational activities.Conclusion The participants perceived the various pedagogical strategies positively, which shows the value of a broad and diverse educational approach, customised to local settings and including game-based activities, to enhance learning among healthcare professionals
Brazilian Flora 2020: Leveraging the power of a collaborative scientific network
International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
