26. Effect of alternative sanitary treatments in the quality of seed of grape tomato produced under organic management / Efeito de tratamentos sanitários alternativos na qualidade de sementes de tomate cereja produzidas sob manejo orgânico
As sementes produzidas sob manejo orgânico têm atualmente grande importância, pois de acordo com a legislação vigente, a produção orgânica deve ser baseada em sementes produzidas sob manejo orgânico. Entretanto, são escassos na literatura trabalhos relacionados à produção, qualidade fisiológica, armazenamento e tratamento de sementes produzidas

27. ECONOMIC VALUATION OF RURAL QUINTAIS - THE CASE OF FARMERS IN CONNECTION WITH Cooperafis (AGRICULTURAL COOPERATIVE FAMILY Itapuranga-GO) / VALORAÇÃO ECONÔMICA DE QUINTAIS RURAIS O CASO DOS AGRICULTORES ASSOCIADOS À COOPERAFI (COOPERATIVA DE AGRICULTURA FAMILIAR DE ITAPURANGA-GO)
The valuation of family farming by Brazilian society constitutes an important tool for local development, since it uses scarce resources like land, labor force, efficiently. The rural homegardens are important production systems to complement other forms of land use, which besides providing food security for farmers, they perform functions aesthetic, recreat

28. Bioecological studies on Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) in the control of Diaphorina citri Kuwayama, 1907 (Hemiptera: Psyllidae) / Estudos bioecológicos de Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) para o controle de Diaphorina citri Kuwayama, 1907 (Hemiptera: Psyllidae)
Since 2004, have been detected in citrus-growing areas of São Paulo, the bacterias that are responsible for the main disease of citrus worldwide, known as greening or huanglongbing. The widespread distribution in Brazil of the vector psyllid, Diaphorina citri and the presence of the pathogen in citrus-growing areas is a limiting factor for production. Tamar

29. Análise qualitativa de um projeto com uma família de agricultores no assentamento rural Fazenda Pirituba II / Qualitative analysis of a project developed with a family of agriculturists in fazenda pirituba ii rural settlement
Agroecology emerges as a science in the 70s of the 20th century. It criticizes convencional agriculture based on a paradigm that passes over social individual connected to natural resources management what brings up serious social and environmental consequences. It proposes an alternative to the subject division of positivist science and incorporates social

31. Agroecological innovations for household farming: a case study on the agroforest systems in Upper Jequitinhonha / InovaÃÃes agroecolÃgicas para a agricultura familiar: um estudo de caso sobre sistemas agroflorestais no Alto Jequitinhonha - MG.
The process of modernization of farming brought about significant transformations in Brazilian rural milieu. The âgreen revolutionâ was considered by many authors a harmful model in environment and socially excluding. It was characterized by the standardization of the agricultural production processes, disregarding the countryâs regional particularities.

32. Frações orgânicas e agregação do solo em diferentes sistemas de produção orgânico. / Organic fractions and soil aggregation in different organic production systems.
O uso e manejo adequados do solo inferem diretamente na sua qualidade e são aspectos fundamentais ao desenvolvimento de uma agricultura sustentável. O objetivo deste trabalho foi avaliar a influência de sistemas de manejo agrícola orgânico nas diferentes frações da matéria orgânica e agregação do solo, e correlacioná-las com mudanças nas proprie

33. Indicadores de qualidade do solo sob sistema de produção agrícola convencional em conversão para agroecológico
Microbial and biochemical indicators of soil quality, mainly those related to carbon and nitrogen cycling, are useful to access the effect of soil management and its effects on the sustainability of the agroecosystems. The aim of this work was to access changes occurring in the soil due to the transition from conventional to agroecological agricultural syste

34. Performance of lettuce (Lactuca sativa L.) intercropped with different green manures / Desempenho de alface (Lactuca sativa L.) consorciada com diferentes adubos verdes
The agricultural production systems currently used are in most cases ecologically impacting and use high amounts of natural resources. Within this context, vegetable production is an activity characterized by intensive land use and high demand for farm inputs, requiring the adoption of an agroecological management approach for sustaining its production. Thus

35. Monitoramento do uso da terra e dos níveis de nutrientes do solo no Sistema Integrado de Produção Agroecológica utilizando geoprocessamento. / Monitoring of land use and soil nutrients levels on an integrated agroecological production system by image processing.
Agroecological production systems are more complex than conventional ones, since a series of crops follow in sequence or are intercropped to achieve high diversity and maximize soil nutrient recycling. The full understanding of these systems require systemic analyses and therefore, adequate tools. To understand soil fertility evolution, heterogeneity should

36. Variabilidade espacial da qualidade físico-hídrica do solo de um sistema em produção agroecológica. / Spatial variability of physical - hydric soil quality of an agroecological production system
The knowledge of physical hydric soil quality indicators is crucial during planning and management of agriculture activities. Many articles had been written to identify and to correlate the physical hydric soil quality and crop production. However, the most part of the results are not reliable for mapping spatial variability, mainly in large areas. The objec
