Agronomic performance and genetic diversity of cowpea lines under conditions of Recôncavo da Bahia

O feijão-caupi [Vigna unguiculata (L.) Walp] está entre as principais culturas de subsistência para pequenos agricultores do Norte e Nordeste do Brasil. Contudo, sua produtividade é baixa em comparação a outras regiões do país, podendo estar associada à utilização de cultivares não adaptadas. Assim, objetivou-se identificar as linhagens de feijão-caupi mais produtivas e adaptadas às condições do Recôncavo da Bahia. O experimento foi conduzido em Cruz das Almas-BA, localizada no Recôncavo da Bahia, sendo constituídas por 16 linhagens e quatro cultivares de feijão-caupi, totalizando 20 tratamentos que foram distribuídas em delineamento experimental em blocos casualizados e quatro repetições. No momento em que todas as vargens da parcela se encontravam secas foi realizada a colheita e em seguida foi realizada a avaliação das características agronômicas, comprimento médio das vagens; massa de cinco vagens; massa dos grãos em cinco vargens, número de grãos em cinco vagens e número médio de grãos por vagem. Os dados foram submetidos à análise de variância e suas médias foram agrupadas pelo teste Scott-Knott, visando complementar as informações e demonstrar a variabilidade genética entre as linhagens foi realizada análise multivariada. Houve diferenças entre as linhagens para as cinco características avaliadas e a partir da análise de componentes principais e análise de agrupamento e heatmap foi observada a formação de quatro grupos com destaque para as linhagens MNC03-737F-5-9 e MNC03-736F-7, que exibiram potencial agronômico em relação às demais linhas e cultivares avaliadas, sendo, portanto, recomendadas para produção de feijão-caupi nas condições do Recôncavo da Bahia.Cowpea is among the main subsistence crops for small farmers in the North and Northeast of Brazil. However, its productivity is low compared to other regions of the country, and may be associated with the use of non-adapted cultivars. Thus, the objective was to identify the most productive cowpea lines and adapted to the conditions of the Recôncavo da Bahia. The experiment was carried out in Cruz das Almas-BA, located in Recôncavo da Bahia, consisting of 16 lines and four cultivars of cowpea totaling 20 treatments that were distributed in a randomized block design and four replications. At the moment when all the varieties in the plot were dry, the harvest was carried out and then the evaluation of the agronomic characteristics was carried out. average length of the pods; weight of five pods; grain weight in five varieties, number of grains in five pods and average number of grains per pod. The data were subjected to analysis of variance and their means were grouped by the Scott-Knott test, in order to complement the information and demonstrate the genetic variability between strains. Multivariate analysis was performed. There were differences between the strains for the five characteristics evaluated and from the analysis of main components and cluster analysis and heatmap, the formation of four groups was observed, with emphasis on the strains MNC03-737F-5-9 and MNC03-736F-7, which exhibited agronomic potential in relation to the other lines and cultivars evaluated, and are therefore recommended for the production of cowpea under the conditions of the Recôncavo the Bahia

The causes of school evasion in a private higher education institution: case study

The objective of this research was to identify the causes that motivated the students to evade the courses of a private Higher-Education Institution - IES, in the city of Porto Velho-RO. It was intended to raise the number of students evaded by periods and courses in recent years to assess the impact of school evasion on HEI management decisions. To obtain results, we used the interpretation of data obtained through quantitative and qualitative research, questionnaires and interviews

Agronomic evaluation and quality flour among cassava cultivars under field conditions

O Brasil se destaca entre os cinco maiores produtores de mandioca do mundo, contudo, a produtividade varia no território nacional, devido, dentre outros fatores, a utilização de variedades inadequadas para região, nesse sentido, objetivou-se selecionar cultivares de mandioca nas condições do Recôncavo baiano, em época de colheita com 12 meses. No trabalho foram utilizadas 15 cultivares distribuídas em blocos casualizados com três repetições, avaliando-se sete características agronômicas e a qualidade da farinha. Os dados foram submetidos a análise de variância e multivariada. Pela análise de variância foi observada variação para todas as características com exceção do comprimento da raiz. Produtividade acima de 35,00 t. ha-1 foi registrada para todas as cultivares, com destaque para a cultivar Irará que atingiu 47,00 t. ha-1 e médias superiores para as características agronômicas e de qualidade de farinha, contrariamente às cultivares BRS Tianguá e BRS Jarina. Correlações positivas de alta magnitude foram registradas entre as características de qualidade da farinha, com destaque para as cultivares BRS Amansa burro e 9783/13. As cultivares Irará, BRS Amanso burro e 9783/13 se destacaram para as condições desse estudo, podendo ser utilizadas pelos produtores de mandioca do Recôncavo da Bahia.Brazil stands out among the five largest cassava producers in the world, however the productivity is quite varied in the national territory, being associated, among other factors, the use of varieties unsuitable for the region, in this sense, the objective was to select cassava cultivars under the conditions of the Recôncavo Bahian, at harvest time with 12 months The work was conducted in Recôncavo da Bahia using 15 cultivars distributed in Randomized Blocks with three replications, evaluating seven agronomic characteristics and quality of flour. The data were subjected to analysis of variance and multivariate. Through the analysis of variance, variation was observed for all characteristics evaluated, except for the root length. Yields above 35,00 t. ha-1 were recorded for all cultivars with emphasis on the cultivar Irará, which reached a yield of 47,00 t. ha-1, this cultivar also stood out in the multivariate analysis composing an isolated group and lower results were recorded in BRS Tianguá cultivars and BRS Jarina, who had formed the third group with below average results for agronomic and flour quality characteristics. Positive correlations of high magnitude were recorded between the characteristics of flour quality with emphasis on the cultivars BRS Amansa burro and 9783/13. The cultivars Irará, BRS Amansa burro and 9783/13 stood out for the conditions of this study, and can be used by cassava producers in the Recôncavo da Bahia

ANÁLISE DA MUDANÇA NA COBERTURA VEGETAL DA RESERVA ECOLÓGICA DOIS IRMÃOS RECIFE (PE)

Com o avanço da urbanização da cidade do Recife a Reserva Ecológica de Dois Irmãos, sofre constante pressão da população. Sendo um dos maiores trechos de mata atlântica da cidade, a reserva também abriga três grandes açudes, dentre eles o açude do Prata que abastece a população local e tem boa qualidade, porém caso a floresta não seja preservada a qualidade desses afluentes também serão diretamente afetados. Foi realizada uma análise através de ortofotocarta da região, comparando as imagens de 1975 e de 2015 do Parque estadual. Os resultados mostraram que mesmo com a tendência de aumento do desmatamento, a partir da expansão urbana, na cidade do Recife, a cobertura vegetal no local do estudo ainda se apresenta preservada, o que dá destaque as políticas conservação realizadas no local. 

Kailo: a systemic approach to addressing the social determinants of young people’s mental health and wellbeing at the local level [version 1; peer review: awaiting peer review]

The mental health and wellbeing of children and young people is deteriorating. It is increasingly recognised that mental health is a systemic issue, with a wide range of contributing and interacting factors. However, the vast majority of attention and resources are focused on the identification and treatment of mental health disorders, with relatively scant attention on the social determinants of mental health and wellbeing and investment in preventative approaches. Furthermore, there is little attention on how the social determinants manifest or may be influenced at the local level, impeding the design of contextually nuanced preventative approaches. This paper describes a major research and design initiative called Kailo that aims to support the design and implementation of local and contextually nuanced preventative strategies to improve children's and young people’s mental health and wellbeing. The Kailo Framework involves structured engagement with a wide range of local partners and stakeholders - including young people, community partners, practitioners and local system leaders - to better understand local systemic influences and support programmes of youth-centred and evidence-informed co-design, prototyping and testing. It is hypothesised that integrating different sources of knowledge, experience, insight and evidence will result in better embedded, more sustainable and more impactful strategies that address the social determinants of young people’s mental health and wellbeing at the local level
