Mangueira: melhoramento genético, variedades e mercado.
No full textA cultura da mangueira ocupa uma extensa área do território brasileiro, gerando, no ano de 2018, uma produção superior a 1 milhão e 300 mil toneladas. Embora praticada em vários estados, a mangiculturanacionalé mais representativa em determinadas regiões. A principal região é o Vale doSubmédioSão Francisco, que,responsável por quase 90%das exportações brasileiras, ampliou a área colhida de 39 mil hectares para 49 mil hectares em 2019. As demais regiões que se destacamsão os municípiosde Livramento de Nossa Senhorae Dom Basílio, na Bahia, com 12 mil hectares, o oeste de São Paulo, com 8 mil hectares, e o norte de Minas Gerais, com 7 mil hectares, considerando-se estimativas de 2018. As quatro regiões já somavam, em 2019, mais de 76 mil hectares (Lima et al., 2018; Anuário Brasileiro de Horti e Fruti, 2019, 2020
Vida literária e desencantos: uma história da formação intelectual de Lima Barreto (1881-1922)
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.O pensamento  conceito abordado aqui enquanto um processo vinculado à formação intelectual do sujeito  pode ser um fenômeno multifacetado e permanecer em aberto. Com base nessa premissa, os diagnósticos elaborados por Lima Barreto (1881-1922) sobre a modernidade serão mapeados a partir das mediações culturais que estabeleceram com ícones bastante representativos das letras modernas, como, por exemplo, Anatole France, Tolstói, Dostoievski, Thomas Carlyle e Jules Gaultier. É preciso esclarecer, de antemão, que esse trabalho constitui um ponto de vista, entre muitos possíveis, sobre as relações mantidas por Lima Barreto e a cultura escrita que circulou em seu tempo. Buscar compreender alguns nuances do processo de maturação intelectual desse escritor, a partir das influências que recebeu das literaturas estrangeiras, não significa crer no argumento de que a criatividade barretiana foi um tipo de reflexo das ideias europeias. A partir, principalmente, das impressões de leitura de Lima Barreto e do catálogo de sua biblioteca particular, pretendo comparar as ideias literárias desse escritor com as de outros homens de letras que fizeram parte de sua geração. Por meio desse procedimento, é possível trabalhar com a perspectiva de que os diagnósticos de Afonso Henriques sobre a política, a modernidade brasileira e a vida intelectual, na Primeira República, podem dialogar com contextos documentais bem mais amplos do que o da história nacional.Abstract : The thought - a concept discussed here as a process linked to the intellectual formation of the subject - can be a multifaceted phenomenon and still remain open. Starting from this premise, the diagnoses elaborated by Lima Barreto (1881-1922) about modernity will be mapped starting from the cultural mediations that have established quite representative icons of modern letters, for example, Anatole France, Tolstoy, Dostoyevsky, Thomas Carlyle and Jules Gaultier. We must clarify in advance that this work is a point of view, among many possible, on relations maintained by Lima Barreto and the written culture that circulated in his time. Search to understand some nuances of intellectual maturation process of this writer, starting from the influences received from foreign literature, does not mean believing in the argument that the creativity of Barreto was a kind of reflection of European ideas. From mainly of Lima Barreto s reading impressions and his personal library catalog, want to compare the literary ideas of this writer with the other brazilian authors that were part of his generation. Through this procedure, is possible work with the perspective that the diagnostics about politic, brazilian modernity and the intellectual life, in the First Republic, made by Lima Barreto, be able to inserteds in documentary contexts more extensive than the local history

Características da mangicultura no Vale do Submédio São Francisco.
No full textO cultivo da mangueira na região semiárida brasileira caracteriza-se por práticas agronômicas intensivas, alto investimento tecnológico e produção orientada para o mercado exterior. Estas características são possíveis devido as condições climáticas favoráveis ao rápido metabolismo dos tecidos vegetais, o que aliado a práticas agronômicas adequadas permitem a produção precoce, o encurtamento dos ciclos e fases fenológicos e a possibilidade de frutos com coloração, teores de açucares e ácidos orgânicos compatíveis com os padrão de qualidade mais exigentes
