Description
An account of the resource
Estimular o empreendedorismo da juventude rural, visando sua inserção no protagonismo das mudanças que ocorrem nas comunidades, torna-se, a cada dia, mais relevante para o desenvolvimento rural sustentável. O restrito acesso às políticas públicas adequadas tem deixado muitos agricultores/as familiares, em especial os/as jovens, desacreditados/as da viabilidade de suas atividades. Este texto apresenta os resultados do projeto de extensão 'Empreendedorismo rural: consolidação da Empresa Júnior de Agronomia da UESB', desenvolvido com jovens da agricultura familiar - estudantes do ensino médio do Colégio Estadual Luís Eduardo Magalhães, do município de Caraíbas-BA. Foram realizadas oficinas de empreendedorismo rural e de plano de negócio agrícola, cursos de avicultura caipira e de horticultura em canteiros econômicos, fundamentados na realidade local. Oitenta e cinco jovens foram beneficiados e receberam kits com o material básico para iniciarem a implantação da avicultura caipira ou o cultivo de hortaliças em canteiros econômicos. A partir do conhecimento adquirido e dos kits que receberam, os jovens iniciaram uma atividade empreendedora própria, esperando-se, portanto, que possam desenvolver maior vínculo com o meio rural e perfazer uma renda que permita sua permanência no campo.

El artículo analiza las condiciones de la producción campesina tomando en cuenta las investigaciones recientes sobre los paisajes agrarios y las pautas de residencia así como los elementos que en las fuentes literarias permiten identificar patrones de conducta compatibles con el modelo de la economía campesina. Se estudian asimismo los debates acerca del despegue en el mundo griego de una agricultura familiar intensiva y el rol de los modelos explicativos 'demográficos'. Finalmente, se plantea la relación entre los campesinos y el mercado considerando la presencia de esclavos en el marco de las economías domésticas. La conclusión central hace hincapié en la incidencia de la noción de autarquía en la organización de las unidades campesinas y los límites que éstas encontraban para cumplir con ella.The article analyzes the conditions of peasant production taking into account recent researches on agrarian landscapes and residence patterns as well as the elements that in the literary sources allow identifying patrons of behaviour compatible with the model of the peasant economy. It is also studied the debates about the development of an intensive family agriculture in the Greek world and the role of 'demographic' explanatory models. Finally, it is considered the relation between peasants and the market considering the presence of slaves within the domestic economies. The central conclusion insists on the incidence of the notion of autarky in the concrete organization of peasant units and on the limits that these found to fulfill with it.

O aumento da procura no mercado de frutas frescas junto com a elevada cotação do suco de maracujá no mercado nacional e internacional fez crescer o interesse pela fruta, em especial o maracujá-roxo no centro sul do país visando a exportação. O presente trabalho objetivou avaliar os efeitos de bioestimulante na emergência e desenvolvimento de plântulas de maracujazeiro 'Roxinho do Kênia' (Passiflora edulis Sims.) quando propagados de forma sexuada. Os tratamentos foram constituídos pelas concentrações do produto comercial Stimulate®: testemunha (sem bioestimulante); 6; 12; 18; 24 e 30 mL.kg-1 de sementes. Foram avaliadas a porcentagem de emergência de plântulas, número de folhas, massa seca da parte aérea, caule e raiz(g), comprimento da raiz (mm), diâmetro e comprimento do caule(mm), área foliar e clorofilas 'a' e 'b. A aplicação de bioestimulante nas doses de 6 e 12 mL.kg-1 promove o aumento da porcentagem de emergência de plântulas de Passiflora edulis Sims em um menor tempo. O uso do mesmo também promove o desenvolvimento das plântulas, com melhores resultados para as dose de 12 e 24 mL.kg-1 de sementes tratadas.

Esta investigación, tuvo como objetivo principal establecer indicadores de calidad en el proceso de fermentación anaerobia de bioles de producción local y conocer sus principales componentes químicos. Se realizó la determinación periódica de los parámetros físico químicos 'in situ' y en laboratorio, luego se realizó un tamizaje químico, evaluándose además su actividad fertilizante mediante la determinación de macro y micronutrientes. Se observó que los bioles con bioactivad presentan los siguientes intervalos de confianza en sus parámetros físico-químicos: pH entre 3,4 y 4,6; conductividad entre 16,2 y 23,84 mS/cm; densidad entre 1,030 y 1,060 Kglm3. El tamizaje químico permitió determinar de forma preliminar la presencia de los siguientes grupos químicos: alcaloides, terpenos/esteroides, quinonas, fenoles y taninos, entre otros, algunos de los cuales han sido asociados a su actividad antimicrobiana y promotora del crecimiento vegetal, constituyendo estos resultados los primeros generados en el país sobre el estudio de bioles de producción local, permitiendo el diseño de una metodología útil para la evaluación de otros bioinsumos de uso agrícola. Para el análisis estadístico del proceso de producción, se obtuvo un modelo de regresión polinómica de fado dos, para cada variable; además del coeficiente de determinación del modelo (R-). También se analizó la tendencia central y dispersión de las variables (parámetro de calidad), a través del promedio y la desviación estándar en el proceso y producto terminado.

Description
An account of the resource
El desarrollo de estrategias de mejora que vinculen la diversidad biológica y los servicios productivos y de regulación de los cultivos es un imperativo cuando se trata de la promoción de una agricultura de bajos-insumos (en la que se incluye la agricultura ecológica). En los sistemas de bajosinsumos, la producción tiene que basarse en los utensilios suministrados por la diversidad dentro y entre cultivos, usar los recursos locales e incluir a las variedades tradicionales, como fuente de genes útiles y de genotipos, para el desarrollo de nuevas variedades o para que las variedades locales evolucionen como nuevas poblaciones. Los sistemas de bajos-insumos requieren una mejora descentralizada y participativa diseñada para incorporar el 'know-how' de los agricultores y la perspectiva de los consumidores. Caracteres del cultivo que permitan la reducción de los insumos, como la eficiencia en el uso de la asociación con especies beneficiosas tales como los polinizadores aumentarán en importancia. Este artículo describe aproximaciones de mejora dirigidas a la implementación de una sinergia entre los servicios de producción y de regulación prestados por la agricultura en el contexto de sistemas de bajos-insumos.

An account of the resource
The objective of the study was to characterize the 'rice' production plots, a concerted survey of 50 questions used was, ofwhich 35 questions related were to the socio-economic component and 15 related to the environmental component. Amultivariate analysis carried out was to form groups or clusters, whose purpose was to group the plots and formconglomerates (clusters) with a high degree of internal homogeneity and external heterogeneity. For the processing of thedata, the statistical software Info Stat used. Was Among the most important results, it was found that the majority ofproducers own their plots, sow between 0.5 to 5 hectares, the yield of grain rice is between 5 000 to 8 000 kg/ha and all doconventional agriculture. The conglomerate analysis classifies the plots into 6 groups, the producers of conglomerate 1 sharethe greatest number of variables (21), having in common the variables: ownership of the plot, use of chemical fertilizers,burning of weeds and harvest residues, use of agrochemicals. The producers of conglomerate 5 have 12 variables incommon, among them: they do not incorporate organic matter, they do not rotate crops, they do not use biological control,and they do not use repellents. It recommended is to promote the rotation and association of crops under the diversityprinciple; likewise, to promote the self-sustained fertility of the soil, and to include in the productive process, the integratedmanagement of insect pests and phytopathogens.

O presente artigo refere-se ao projeto de pesquisa e de extensão denominado 'O uso e a apropriação de TICs pela agricultura familiar no Vale do Caí - RS', financiado pelo edital do MCTI/CNPq. O objetivo deste artigo é traçar o perfil socioeconômico dos agricultores familiares do Vale Caí e verificar o uso das TIC (Tecnologias de Informação e Comunicação) pelos agricultores familiares. Foram aplicados 375 formulários de entrevistas semiestruturados com informações socioeconômicas e culturais que serviram de base para a formação do perfil dos agricultores estudados e questões relativas ao uso e à apropriação das TIC. Essas informações foram tabuladas e verificou-se que os agricultores familiares do Vale do Caí, de acordo com resultados levantados, apresentam idade média de aproximadamente 42 anos, moram com a família na propriedade rural, cultivam principalmente a silvicultura e a citricultura, pouco mais da metade tem rendimentos de até 2 salários mínimos ao mês e apresentam baixa escolaridade, basicamente o ensino fundamental incompleto. No que tange ao uso das TIC destaca-se que somente 16 propriedades não possuem bens de comunicação e de informática e em relação ao acesso à internet, constata-se que 46,1% dos entrevistados acessam diariamente a rede.

Description
An account of the resource
Chemical fertilisers are rarely avaiable to poor farmers, for whom the nitrogen (N) is often the most limiting element for cereal grain production. The objective of this study was to quantify the contribution of biological nitrogen fixation (BNF) to groundnut (Arachis hypogaea) and velvet bean (Mucuna pruriens) crops using the 15N natural abundance (delta15N) technique and to determine their residual effect and that of a natural fallow, on growth and N accumulation by two rustic maize varieties. The contribution of BNF calculated from delta15N data was 40.9, 59.6 and 30.9 kg ha-1, for groundnut, velvet bean and the natural fallow, respectively. The only legume grain harvested was from the groundnut, which yielded approximately 1.000 kg ha-1. The subsequent maize varieties ('Sol de Manhã' and 'Caiana Sobralha') yielded between 1.958 and 2.971 kg ha-1, and were higher after velvet bean for both maize varieties and 'Sol da Manhã' groundnut, followed by 'Caiana' after groundnut and, finally, the natural fallow. For a small-holder producer the most attractive system is the groundnut followed by maize, as, in this treatment, both groundnut and maize grain harvest are possible. However, a simple N balance calculation indicated that the groundnut-maize sequence would, in the long term, deplete soil N reserves, while the velvet bean-maize sequence would lead to a build up of soil nitrogen.Fertilizantes químicos raramente estão disponíveis aos agricultores com poucos recursos econômicos, e assim o N é, freqüentemente, um elemento mais limitante para a produção de grãos. O objetivo deste trabalho foi quantificar a contribuição da fixação biológica de nitrogênio (FBN) às culturas de amendoim (Arachis hypogaea) e mucuna (Mucuna pruriens), por meio da técnica de abundância natural de 15N e determinar o efeito residual das leguminosas e do pousio sobre o crescimento e acumulação de N em duas variedades de milho. A contribuição da FBN calculada a partir dos dados de delta15N, foi de 40,9, 59,6 e 30,9 kg ha-1, respectivamente, para amendoim, mucuna e o pousio. A única leguminosa de grão colhida foi amendoim que produziu aproximadamente 1,000 kg ha-1. A produtividade da cultura de milho (variedades Caiana e Sol da Manhã) variou de 1,958 a 2,971 kg ha-1 de grãos, sendo mais alta após mucuna em ambas as variedades de milho e após amendoim na Sol da Manhã, seguida por Caiana após amendoim e por último o pousio normal. Para pequenos agricultores o sistema mais atrativo é o que inclui amendoim seguido pelo milho, uma vez que duas colheitas de grãos são possíveis. Contudo, o cálculo do balanço de N indicou que a seqüência amendoim-milho diminuiria, a longo-prazo, a reserva de N do solo, enquanto a seqüência mucuna-milho ajudaria a aumentar a reserva de N do solo.
