Title A name given to the resource Determinación de la presencia de genes cry en cepas nativas de Bacillus thuringiensis Creator An entity primarily responsible for making the resource Jairo Alonso Cerón Salamanca, Abraham Fuya Quintero, Luis Alejandro Chaparro Giraldo Description An account of the resource A partir de dos tipos de muestras, suelo asociado a cultivos de papa (Solanum tuberosum) y polvo asociado a sitios de almacenamiento de granos (cereales) colectado en las centrales de Corabastos y Paloquemao en Bogotá, se aislaron 88 cepas nativas de Bacillus thuringiensis bacilo grampositivo patógeno de insectos plaga de cultivos agrícolas. De las 88 cepas obtenidas 57 de ellas se escogieron para separarlas posteriormente mediante subcultivos en virtud a sus características fenotípicas al interior de la colonia llevando esto a obtener un número de 145 cepas nuevas para un total de 176 cepas de B. thuringiensis caracterizadas  morfológicamente y por su patrón de formas de las ICPs mediante microscopía de contraste de fases, y de las proteínas Cry arrojado por los perfiles de SDS-PAGE; en el total de cepas hubo presencia predominante de ICPs con forma romboide acompañadas por al menos otras dos formas distintas, y mostraron perfiles electroforéticos de proteínas de peso molecular entre el rango de 130, 116 y 60 kDa. Del total de cepas B. thuringiensis nativas aisladas en este estudio, 59 (30 de suelos y 29 de polvo) fueron analizadas mediante la técnica PCR, encontrando que 100% de ellas son portadoras de alguno de los seis tipos de genes cry1 estudiados cry1Aa5 (71,2%), cry1Ab9 (66,1%), cry1Ac5 (45,8%), cry1Ba1 (39%), cry1Ca3 (49,1%), y cry1Da1 (71,2%); adicionalmente se observó la presencia de productos génicos inespecíficos, posiblemente nuevos, amplificados por la PCR y relacionados con los genes cry1C (55,9%), cry1B (30,5%) y otros genes cry1 no estudiados por este método en al menos el 50% de las cepas estudiadas. De acuerdo con estos resultados se estableció un total de 19 genotipos diferentes según los genes cry1 estudiados, presentados por las cepas nativas en estudio determinando que estos son diferentes en composición genética según la fuente de procedencia del aislamiento, permitiendo establecer estrecha correlación entre el potencial bioinsecticida de las cepas de B. thuringiensis y su fuente de aislamiento. Mediante el estudio hecho con PCR en cepas que se separaron a partir de un aislamiento con variabilidad fenotípica al interior de la colonia, se logró establecer que existen diferencias en la composición genética de genes cry al interior de una misma colonia según se observa por variabilidad morfológica de la misma. Esto conllevó a la propuesta de una hipótesis de trabajo bajo el concepto ecológico de población de individuos de una misma especie, referida por una parte a una posible distribución de funciones al interior de una colonia de B. thuringiensis manifestada por la presencia de individuos que se pueden diferenciar morfológica y genéticamente en algún estadio de su crecimiento cuya interacción podría estar gobernada por principios de organización jerárquica.

Title A name given to the resource Vegetative growth of raspberry (Rubus idaeus L.) ‘Autumn Bliss’ with vermicompost application intercropped with lupine (Lupinus mutabilis Sweet.) Creator An entity primarily responsible for making the resource Enoc Jara-Peña, Ángel Villegas, Prometeo Sánchez, Antonio Trinidad, Alfonso Muratalla, Ángel Martínez Description An account of the resource The present investigation was carried out with objective to determine the response of red raspberry to vermicompost application and lupine (intercropped or not) in the phase of vegetative growth under greenhouse conditions in Montecillo, Mexico. In the experiment 11 treatments were studied with 9 replications per treatment, with a complete factorial (5 × 2) plus an additional treatment consisting of a chemical fertilization with N100 P80 K80. As vegetable material adventitious buds of raspberry were used, statistically significant differences were found between treatments in number of leaves, plant height, cane diameter, fresh and dry matter in raspberry. The biggest response was obtained with 90 and 120 g pot–1 of vermicompost. In general, the lupine intercropped with raspberry permitted a slight competion but favored the biggest development in the foliar area.

However, note that many difficulties in many respects managerial and market access restrictions. Within this context, the main goal of this project was to support the Organization of family farmers in a cooperative (COOFELIZ) of the municipality of happy-mg expected. To this end were undertaken actions such as workshops, training for project planning and preparation, discussions with partners and organizational support intended to help with learning processes for strengthening social COOFELIZ framework. There are indicative of the project has contributed to a better organization of cooperated, allowing access of the cooperative programmes of public policies and elaboration and adoption of a rural extension project with funding from the MDA. Can be concluded that the joints and partnerships formed of family farming organisations are fundamental to promote local development-related actions, and the involvement of members on the actions of cooperatives is fundamental to your organizational growth and overcoming the problems faced by enterprises in solidarity.

Title A name given to the resource The management of molasses agroindustries in the Noroeste Missões-RS, Brazil, by the perception of their managers Creator An entity primarily responsible for making the resource Denise Medianeira Mariotti Fernandes, Gabriel Thomas Description An account of the resource The study on the management of molasses agribusinesses and other sugarcane derivatives of Noroeste Missões-RS, Brazil, in the perception of their managers, is needed so that information and data can be analyzed and transformed into knowledge. This type of study contributes to the development of the sector, job creation and income increment, which keeps younger generations in the field in the succession of family agribusinesses. In this research work it was noticed that the managers surveyed do not adopt formal management tools such as schedules and worksheets for the division of labor and financial controls, and do informally, without sometimes not realize that adopt some administrative tool. Advantages have been reported in the creation and legalization of agribusinesses process, such as increased employment, product mix and production volumes for marketing, in addition to increased sales, profitability and open up new domestic and foreign markets. These advantages outweigh any disadvantages cited by some managers, as an increase in taxes, delay in return on the initial investment and various additional costs. The brown sugar and the molasses are the products manufactured and sold within the sample of the Northwest Region Missions/RS, and the sugar has a representative rate of 51.8% and 41.6% molasses. Within the agricultural industries most representatives of production and marketing to highlight the F, G, with 29% and 25% respectively of the total produced products. Although, it was realized that the organic seal has more significant impact than the flavor gaucho seal forward the opening of new domestic and foreign markets for export, and two of the seven agribusinesses sample have permission to use the labels. Finally, glimpses the horizon a framework for future knowledge in the industry, which may come through new research, for analysis in greater depth, adding to is sample those informally, that is, managers system handicraft production of sugar cane derivatives.

Title A name given to the resource Agricultural Sustainability and Agrarian Geography: The Context of Organic Agriculture in Rio de Janeiro State Creator An entity primarily responsible for making the resource Regina Cohen Barros Description An account of the resource The aim of the present study is to contribute to current debates in AgrarianGeography concerning the dynamics of Brazilian rural space as exemplified by the case of Rio de Janeiro State. Rio de Janeiro presently is experiencing rural transformation provoked by the increasing urbanization of the countryside so redefining the geographical concepts of “rural” and “urban” within historical and contemporary processes of capitalist development. Within this general process, organic agriculture has emerged within vegetable farming in the Região Serrana Fluminense. As most vegetable production in this region is undertaken using conventional modern methods, organic farming for the metropolitan market is marketed through new separate channels so as to guarantee product authenticity. In the beginning, farmers were of urban origin, but as organic production expanded in response to increasing urban demand, some local farmers shifted from conventional to organic methods.

Foram analisados os seguintes parâmetros de produtividade e qualidade nutricional: massa verde, massa seca e teor de proteína bruta das duas culturas. O aumento da salinidade da água de irrigação de 2,89 dS/m para 3,69 dS/m reduziu a altura das plantas, o teor de proteína bruta, a produtividade de massa verde e seca das duas culturas. A produtividade do sorgo em relação a todos esses parâmetros foi superior àquela das duas cultivares do capim elefante, sendo a produtividade da cultivar do capim roxo relativamente superior àquela do capim verde. Dessa forma, o sorgo BRS Ponta Negra se apresenta como alternativa de sustentabilidade socioeconômica para o aproveitamento da água residual da dessalinização em sistema que apresente condições de salinidade igual ou inferior à estudada, garantindo, assim, uma fonte alternativa de renda e emprego para a agricultura familiar ou para Associação de Usuários de Água na região semiárida.

Title A name given to the resource Allelopathic effects of orange (Citrus sinensis L.) peel essential oil Efeitos alelopáticos do óleo essencial da casca da laranja (Citrus sinensis L.) Creator An entity primarily responsible for making the resource Jose Pedro Nepomuceno Ribeiro, Maria Inês Salgueiro Lima Description An account of the resource Crop weeds are the main problem in agriculture, causing a worldwide annual loss of about US$95 billion. The principal method for control is the use of synthetic herbicides. The continued use of these products increases crop costs, reduces crop quality, and leaves toxic residues in the environment, which are a threat to human and livestock health. Therefore, there is a demand for environmentally friendly methods of weed control. The use of allelopathic compounds from crop residues is an alternative. Orange is one of the biggest crops in the world, and its cultivation generates large amounts of residues. There is strong evidence of bioactivity in orange peel essential oil. Therefore, the objective in this work was to verify the allelopathic proprieties of this oil. We extracted the oil from the peels of recently discarded oranges using water vapor flow with a Clevenger extractor, and tested it against the growth of Euphorbia heterophylla L. and Ipomoea grandifolia (Dammer) O'Donell seedlings when placed in contact with the oil vapor. The results were both quantitative and qualitative in the inhibition of the seedlings.Plantas daninhas são o principal problema da agricultura no mundo, causando anualmente um prejuízo de U$95 bilhões. A principal forma de combate às plantas daninhas são os herbicidas sintéticos. Entretanto, o uso continuado desses produtos encarece a produção, reduz a qualidade dos alimentos, deixa resíduos tóxicos no ambiente e ameaça a saúde humana e animal. Existe assim, uma demanda por técnicas menos agressivas de controle. O uso de compostos alelopáticos de descartes de culturas para esse fim é uma alternativa. A laranja é uma das maiores culturas do mundo, e gera grandes quantidades de resíduos. Existem evidências da bioatividade no óleo essencial da casca da laranja. Nesse trabalho, nosso objetivo foi verificar a existência de propriedades alelopáticas desse óleo. Para isto, extraímos o óleo por arraste de vapor de água utilizando o aparelho de Clevenger, e colocamos os produtos volatilizáveis do óleo essencial em contato com plântulas de Euphorbia heterophylla L. e Ipomoea grandifolia (Dammer) O'Donell. O resultado foi inibição tanto quantitativa quanto qualitativa das plântulas Date A point or period of time associated with an event in the lifecycle of the resource 2012 Subject The topic of the resource Agricultura orgânica, Controle de pragas, Crop residues, Limonene, alelopatia, allelopathy, descartes de cultivos, limoneno, organic agriculture, plantas invasoras de culturas, weed controly, weeds Identifier An unambiguous reference to the resource within a given context 10.1590/S0102-33062012000100025 Source A related resource from which the described resource is derived Acta Botânica Brasílica Publisher An entity responsible for making the resource available Sociedade Botânica do Brasil Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Botany Relation A related resource <a href="http://www.scielo.br/scielo.php?script=sci_arttext&amp;pid=S0102-33062012000100025" target="_blank" rel="noreferrer noopener">http://www.scielo.br/scielo.php?script=sci_arttext&amp;pid=S0102-33062012000100025</a>
