RESUMO
O objetivo do trabalho foi verifi car a efi ciência da co-digestão anaeróbia dos dejetos suínos com crescentes níveis de adição de óleo de descarte e lipase. Foram testadas quatro doses de óleos (8, 12, 16 A biodigestão anaeróbia apresenta-se como uma excelente alternativa para o tratamento e reciclagem energética dos nutrientes contidos nos dejetos de suínos, reduzindo o potencial poluidor e os riscos sanitários, além de promover a geração do biogás.No entanto os rendimentos de biogás podem variar em função da qualidade do resíduo adicionado ao biodigestor e grau de diluição, conforme observado por ORRICO JÚNIOR et al. (2010)
The main challenge encountered in agriculture today is to produce a healthy food for a growing population that is increasingly concerned with the health and food they are consuming, thus opting for organic foods because they have a high nutritional value and food safety. Banana is the second most consumed fruit in the world for its easy access, and when introduced into the organic system, the value of the crop is added. The objective of this work was to show the ways of production of ’Prata Anã’ banana with organic fertilization, showing the benefits, management, productivity and other details regarding the production and conservation of the environment. This work had as the research method used, the descriptive one, where the techniques of data collection in articles, books, theses and dissertations were used. Thus, there are practices, such as organic agriculture, that contribute to reducing the impacts produced by the use of pesticides. By making use of organic fertilizer the soil becomes more productive and fertile, increasing its biodiversity and improving the quality of the food produced. With the production of organic banana, it is desired that the producer has a distinct market with a differentiated product, being environmentally friendly, economically viable and socially fair. This paper aims to show the processes for the implementation of a banana plant, in order to help instruct potential stakeholders.
This study aimed to obtain more uniform ripening of the fruits harvested by applying growth regulators Ethephon and Mathury™, aimed at improving the quality of coffee drinks. Was used to cultivate Tupi Yellow (IAC 5162), planted in December 2008. The experimental design was a randomized blocks, being employed five treatments: T1 Application Mathury™ to 113 days prior to collection (DAC); T2 Application Mathury™ after 85 DAC; T3 Application Mathury™ after 57 DAC; T4 Ethephon application when the plants were 30% of cherry fruit and T5- Control (without applications). After sorting the fruit maturation percentage, we selected those who were classified as cherry; these were dried and submitted to analysis: selection by size; classification by type of defects; sugars; solid soluble; electrical conductivity; potassium leaching; titratable acidity; ether extract; pH and sensory analysis. There was a significant difference in the ripening of fruits, noting an increase of 57% the percentage of cherry fruit and 89% reduction of fruit goes through when applied Ethephon. While there have been differences in the percentage of fruit maturation and the physical-chemical analysis, it is concluded that such differences did not influence the coffee beverage quality as it achieved the same standard classification panel test.
Em resposta à instituição do Programa Nacional de Produção e Uso do Biodiesel (PNPB) em 2005, em 2012 o estado de Minas Gerais regulamentou o Pró-Macaúba como política pública de fomento à produção da macaúba, incentivando uma fonte produtora de energia renovável na perspectiva da sustentabilidade ambiental, social e econômica. Neste contexto, este artigo analisa e discute a identificação e articulação governamental dos programas da Secretaria de Estado da Agricultura, Pecuária e Abastecimento (SEAPA/MG) com a efetivação do Pró-Macaúba no Plano Plurianual de governo do período 2012/2015. A metodologia da pesquisa adotou a pesquisa bibliográfica e documental, tendo abordagem qualitativa e finalidade descritiva. Os resultados demonstram que dos 68 programas 35% deles demonstraram identificação e articulações parciais favoráveis ao Pró-Macaúba, 63% não demonstraram nenhuma identificação, e apenas um programa demonstrou-se totalmente identificado e articulado. Não foi possível perceber nos programas da Secretaria finalidades claras de incentivo ao cultivo e comercialização do coco de macaúba. Há sobreposição de programas em unidades executoras distintas, e apesar da resposta dada pelo estado de MG ao PNPB criando e regulamentando o Pró-Macaúba, sua integração aos programas da Secretaria encontra-se limitada, pois os objetivos do Pró-Macaúba não estão efetivamente identificados e articulados nos programas das unidades executoras da SEAPA/MG.
