A mudança do perfil do consumidor, aliada aos riscos da contaminação por agrotóxicos, tem levado à busca de alternativas ecologicamente apropriadas para produção de frutas. Os objetivos deste trabalho foram avaliar a incidência de antracnose, o desempenho e estado nutricional de variedades de mangueira conduzidas organicamente na região de Pindorama-SP. Foram utilizadas 17 variedades de mangueira. O experimento foi instalado em delineamento experimental em blocos completos ao acaso, com 17 tratamentos (variedades) e seis repetições. Foi avaliada a severidade de antracnose nas folhas, através de uma escala diagramática, atribuindo-se notas aos sintomas. Foram avaliados o crescimento e o desenvolvimento (altura da planta, perímetro do tronco e da copa) e o estado nutricional, mediante análise foliar, das diferentes variedades utilizadas. Através dos resultados obtidos, podem-se considerar como muito suscetíveis à antracnose as variedades Bourbon, Rocha e Rosa; e resistentes, as variedades IAC 111, Alfa, Beta e Parvin; as variedades de manga apresentaram o mesmo padrão de crescimento; as maiores alturas da planta corresponderam aos maiores diâmetros do tronco e da copa; a variedade Parvin apresentou o melhor desempenho dentre as variedades estudadas, com relação à resistência à antracnose, altura e diâmetro do caule e da copa, podendo ser recomendada ao cultivo orgânico. As variedades Omega e Alfa também apresentaram bom crescimento, podendo ser indicadas para esse cultivo, pelo menos nessa fase inicial; as variedades Surpresa e Rosa não apresentaram bom desempenho, no campo, em relação às demais, não devendo ser recomendadas para o cultivo orgânico, principalmente a variedade Rosa, bastante suscetível à antracnose. As concentrações de N, P e K foram elevadas na fase vegetativa das plantas, comparadas |à baixa concentração de Ca; houve carência de Boro em todas as variedades estudadas. A manga Rosa, provavelmente, sofreu toxicidade ao excesso de manganês, ocasionando diminuição em seu desenvolvimento.The consumer's profile change, allied to the risk of toxic substances contamination, is inducing the search for ecological alternatives of fruits production. The objectives of this work were to evaluate the anthracnose incidence, the development and nutritional status of mango varieties organically cultivated in Pindorama, SP. Seventeen mango varieties were used. The experiment was designed in completely randomized blocks, with 17 treatments (varieties) and six replications. The anthracnose severity in leaves was evaluated by a diagrammatic scale, with grades attributed to the symptoms. The growth and development (plant height, stem and crown perimeter) and the nutritional state indicated by leaf analysis were used for evaluation of the varietal behavior. The varieties Bourbon, Rocha and Rosa could be considered very susceptible to anthracnose and IAC 111, Alfa, Beta and Parvin were resistant; the mango varieties presented the same growth pattern; the largest plant heights corresponded to the largest diameters of the stem and crown; the Parvin variety presented the best performance among the varieties in relation to the anthracnose resistance, height and diameter of the stem and crown, and could be recommended for organic cultivation. The Omega and Alfa varieties also presented good development and could be indicated for that cultivation, at least in that initial phase; Surpresa and Rosa varieties did not present good field development in relation to the others, and should not be recommended for the organic cultivation, mainly the variety Rosa, which is quite susceptible to anthracnose. The concentrations of N, P and K were higher in the vegetative phase of the plants, when compared to the low concentration of Ca; there was lack of Boron in all the studied varieties; Rosa variety probably suffered toxicity to the excess of manganese, causing decrease in its development.

O objetivo deste estudo é realizar um relato do gestor nacional do Programa Nacional de Alimentação Escolar (PNAE), com ênfase no período de 2003 a 2010. Trata-se de ensaio crítico baseado em revisão da literatura e em dados oficiais. Em relação ao volume de recursos financeiros e ao número de alunos atendidos, observou-se que, em 2003, o Programa executou um total de 954,2 milhões de reais para atender 37,3 milhões de alunos, ao passo que em 2010, o total de recursos passou a ser de 3 bilhões de reais para um total de 45,6 milhões de alunos atendidos. Outros avanços importantes foram os estímulos para a ampliação e o fortalecimento do papel dos Conselhos de Alimentação Escolar e as estratégias normativas para as ações do nutricionista como Responsável Técnico. A Lei nº 11.947/2009 fez o PNAE avançar ainda mais, estendendo o programa para toda a rede pública de educação básica e de jovens e adultos, e recomendando que 30% dos repasses do FNDE sejam investidos na aquisição de produtos da agricultura familiar. São evidentes os avanços nos critérios técnicos e operacionais visando maior flexibilidade, eficiência e eficácia na gestão do PNAE. Espera-se que tais avanços possam se traduzir em melhoria das condições de alimentação e nutrição dos escolares.The scope of this paper is to study the report of the manager of the Brazilian School Nutrition Program (PNAE), with special emphasis on the period from 2003 to 2010. It is a critical essay based on a review of the literature and the official data. It was revealed that the program spent 954.2 million Brazilian reals in 2003 to assist 37.3 million students, and in 2010 the total resources increased to 3 billion Brazilian reals with 45.6 million students attended. Other important advances were the broadening and strengthening of the role of the School Nutrition Councils and the regulatory strategies of nutritionists as Accountable Technicians. Law No. 11.947/2009 gave a new impetus to the PNAE, extending the program to the entire basic public education grid and youths and adults, and recommending that 30% of the funds transferred from the FNDE should be used to acquire products from small farmers. The progress in technical and operational criteria seeking greater flexibility, efficiency and effectiveness in the management of the Program is clear for all to see. It is hoped that these advances will translate into effective improvement in food and nutrition conditions for schoolchildren.

Description
An account of the resource
La cuestión de género en el campo se presenta como un tema que no se ve con la profundidad requerida por el derecho puesto por el Estado en nuestro país. La investigación de este trabajo establece la realidad de las mujeres rurales brasileñas, de clase social baja, a cuestionar el contexto en el que el derecho agrario ayuda a reducir o perpetúa la desigualdad de género en el campo. Se trata de un análisis jurídico en un enfoque particular de la realidad de las mujeres rurales, sobre todo en tono crítico frente a sus dificultades en el acceso a los recursos agrícolas, extensión rural, a los créditos, a la tierra y permanecer en ella, entre otras condiciones que ofrecen las barreras a las actividades autónomas de las mujeres rurales. El objetivo es verificar el papel del derecho agrario en relación con las mujeres rurales e indicar, por medio de la crítica de la ciencia moderna y opresiva, debates necesarios sobre el destaque local y la invisibilidad socio-económica de las mujeres rurales, a partir de posibles enfoques ecofeministas. Por lo tanto, este estudio se estableció con la literatura, de acuerdo con el método deductivo de análisis. En un primer momento, es criticada la opresión patrocinada por el modelo hegemónico de la agricultura, con el fin de fomentar las prácticas de resistencia, especialmente ecofeministas. La falsa exención del derecho agrario en la cuestión de género en el campo, tras una posición a favor del capital. Después, hay contextualización del debate, para que exprese la relación entre el medio rural, el agronegocio, las dificultades de supervivencia que enfrentan las mujeres rurales y el derecho agrario, para relacionar la preocupación con el medio ambiente al feminismo y la necesidad de que el derecho del estado no perpetua la desigualdad de género y construya espacios abiertos de participación efectiva de la mujer rural en tiempos de toma de decisiones. Por último, nociones están indicadas para situar la comprensión de los campesinos y por lo tanto de las mujeres rurales.

An account of the resource
Os sistemas agroflorestais (SAFs) representam uma alternativa agroecológica de produção, sob regime sustentável, para os agricultores familiares na várzea dos Rios Solimões/Amazonas, principalmente no que se refere ao manejo florestal, à diversidade de produtos e à geração de renda. Diante disso, o objetivo deste trabalho foi compreender as diferentes formas de apropriação e de manejo dos recursos naturais através dos SAFs, nos subsistemas roça, sítio e lagos, como componente para a sustentabilidade dos agricultores familiares da localidade Costa da Terra Nova, município do Careiro da Várzea, Amazonas. O método empregado foi o Estudo de Caso com aplicação de questionários, entrevistas e observação participante. A produção familiar na Costa da Terra Nova é representada pelos SAFs, constituído pelos os subsistemas: roça quintal e lago, que proporcionam produtos tanto para subsistência quanto para comercialização local, e estabelecendo a agricultura como fundamental atividade na localidade. O principal produto para comercialização é obtido das hortaliças cultivadas na época da vazante no subsistema roça nas comunidades São Francisco e Nossa Senhora da Conceição; e do extrativismo pesqueiro no subsistema lago, na época da cheia, principalmente na comunidade São José. A criação de animal se dá no subsistema sítio e é apenas para subsistência, sendo as aves e os suínos os principais animais domésticos criados nas três comunidades. Portanto os SAFs tradicionais, constituídos pelos subsistemas, roça, sitio e lago, são responsáveis pela sustentabilidade socioeconômica da localidade pesquisada, servindo, como alternativa agrícola melhor adaptada às condições locais das áreas de várzea na Amazônia.The Agroforest Systems (SAF's) presents an agro ecological alternative of production under sustainable basis for the families farmers, in the várzea (floodplain) of the Solimões/Amazonas Rivers, especially when it is refereed to the forest management, to the products diversity, and the incomes. This study has objective to understand the different ways of appropriation and management of natural resources through SAFs in the different subsystems as clearing, home garden, and lakes as a sustainability component of families’ farmers from Costa da Terra Nova located in the Careiro da Várzea County (Amazon). The methodology used was the case study with the questionnaires applied, interviews and participant observation. The families’ production in the Costa da Terra Nova is represented for agroforestry systems accordingly with the subsystem: farm, home garden and lakes that provide products for their subsistence as much as much for local commercialization. The local communities established the agriculture as a fundamental activity. The main product is obtained from the vegetables grown during the receding water period in the field subsystem in the communities São Francisco and Nossa Senhora da Conceição; and the extrativismo fishing boat on subsystem lake in water period, predominant in community São José. The animal raising is used only for self-subsistence, being the birds and the pigs the mainly domestic animals raising in the three communities. Thus, the traditional agroforestry systems combined with the forest subsystem, clearing, home garden, and lakes are responsible for social-economics sustainability for the studied area, and could be used as an alternative agriculture better adapted for the local conditions at the Amazonian floodplain areas.

Description
An account of the resource
A grande vantagem no emprego da vinhaça concentrada é que ela pode substituir em grande parte os nutrientes da adubação mineral. O uso agrícola da vinhaça concentrada como biofertilizante e os seus benefícios ao solo e às plantas são indiscutíveis. O objetivo desse estudo foi estudar o efeito do uso de vinhaça concentrada, denominada de biofertilizante, em combinação com fertilizantes comerciais, aplicados via fertirrigação, nos componentes de produção da cultura da alface. O experimento foi instalado em ambiente protegido localizado na região centro-norte do Estado de SP. A cultivar utilizada foi a Verônica, o delineamento foi inteiramente casualizado e os tratamentos foram doses de vinhaça concentrada que variaram de 50% a 250% da referência da adubação convencional de potássio. As variáveis analisadas da alface foram: massa fresca total (MFT) massa fresca comercial (MFC), diâmetro do caule (DC), comprimento do caule (CC) e número de folhas (NF). O uso da vinhaça concentrada como biofertilizante líquido proporciona aumento significativo nas principais características morfológicas da alface, resultando em plantas maiores, com maior número de folhas e maior massa fresca. Esse biofertilizante mostra-se realmente eficaz no aumento da produtividade da cultura da alface. Para as condições em que este trabalho foi realizado, pode-se concluir que a aplicação, via fertirrigação, de 2,97 m3 ha-1 de vinhaça concentrada e enriquecida com nitrogênio atende a adubação da cultura da alface.

ResumoExiste atualmente uma preocupação com o processo crescente de ocupação humana desordenada na bacia hidrográfica do rio Pequeno e a sua consequente degradação ambiental. Isso vem sendo demonstrado através de alertas e denúncias feitas por diversos segmentos da sociedade, as quais estão, frequentemente, sendo veiculadas pela mídia local e regional. Essa bacia merece atenção especial na medida em que o rio Pequeno desempenha um papel importante na disponibilização de água superficial para São José dos Pinhais na Região Metropolitana de Curitiba (PR). Diante desse cenário, faz-se mister investigar as atuais condições ambientais da bacia hidrográfica do rio Pequeno, visando avaliar qualitativamente as implicações ambientais decorrentes das diversas práticas agrícolas desenvolvidas pela agricultura familiar, pelo uso e ocupação do solo na bacia em tela. Na presente pesquisa, buscou-se evidenciar a problemática à luz de uma abordagem teórica que contemple o inter-relacionamento das variáveis ambientais, procurando caracterizar os relacionamentos entre os elementos naturais do meio e a dinâmica de uso e ocupação do solo atual. Constatou-se que esta é uma área ambientalmente frágil e, diante dos diversos usos e ocupação dos solos identificados, essa bacia vem passando por um processo de degradação ambiental acentuada, o que promove a deteorização da qualidade de suas águas, tornando assim, iminente o risco da sua perda como abastecimento público, pois a atividade agrícola na bacia, com o manejo intensivo dos solos, o uso de agroquímicos e a urbanização, geram impactos ambientais, tanto em termos de processos erosivos quanto em riscos de contaminação dos recursos hídricos.AbstractThere is, nowadays, a concern regarding the environmental consequences of the growing process of unordered human settlements at Pequeno River hydrographical basin, in São José dos Pinhais (Parana State, South Brazil). Such concern has been demonstrated in frequent denunciations made by several society groups in local and regional midia. The Pequeno River basin deserves special attention mainly because it plays an important role as a source of superficial water to São José dos Pinhais city, at the Metropolitan Region of Curitiba. Provided this scenario, it is essential to determine the present environmental conditions of the Pequeno River basin in order to qualitatively evaluate the environmental implications resulting from the agricultural practices and land use made by the families in that region. The research for this article focused on demonstrating, through a theoretical point of view inter-relating the environmental variables, the linkage between the natural elements and the present land use dynamics. It was found that this basin is an environmentally fragile area that is going through a severe degradation process due to the various uses of land and soil appropriation, generating a poor water quality and increasing the risk of shortage and thus affecting the water supply. The agricultural activities at the basin rely on intensive soil management with chemical control, and combined with the ongoing urbanization, they generate environmental impacts both related to erosive processes and water contamination risks.

Description
An account of the resource
Com a necessidade de buscar alternativas para a produção de um alimento mais saudável e com baixo nível de toxicologia tanto para as pessoas como para o meio ambiente. As chamadas caldas e fertilizantes orgânicos vêm com esse propósito, na qual são utilizadas na agricultura orgânica. Com este intuito as oficinas objetivaram levar aos agricultores técnicas de preparo e uso da calda bordalesa e sulfocálcica para o controle de insetos e doenças, bem como a produção de fertilizante orgânico, por meio do processo de compostagem. Realizada em assentamentos rurais no município de Itapiúna no Ceará para agricultores rurais, levou informações que podem utilizar tranquilamente em suas propriedades, principalmente por se tratar de fácil execução e com baixo custo, tanto as caldas como a compostagem, houve grande interesse pela aprendizagem por parte dos agricultores.

El objetivo de este trabajo fue evaluar la respuesta prolífica de cormos de banano cv. Williams a la aplicación de 6-bencilaminopurina (6-BAP) y un bioestimulante a base de extracto de algas, en condiciones de cámara térmica. En la granja experimental “La Teodomira” de la Universidad Técnica de Manabí, Ecuador, se realizó una investigación desde noviembre del 2013 a abril del 2014. Los tratamientos fueron 6-bencilaminopurina (6-BAP) en concentraciones de 0, 20, 40 y 80 mg/l, y un bioestimulante a base de extractos de algas en dosis de 0, 20, 40 y 80 ml/cormo. La bencilaminopurina fue aplicada en el cormo, y el bioestimulante fue aplicado en drench. El diseño utilizado fue bloques completos al azar con tratamiento factorial A x B, donde los factores fueron 6-BAP y el bioestimulante, los tratamientos, fueron replicados cuatro veces, para un total de 64 unidades experimentales. Se detectaron diferencias significativas (p≤0,0001) para el factor 6-BAP, donde la mayor tasa de multiplicación fue alcanzada con la concentración de 40 mg/l con 47,28 plántulas/cormo. No hubo diferencias significativas (p≥0,9167) para el bioestimulante, ni para la interacción 6-BAP x bioestimulante (p≥0,3789). Se evidenció la formación de tejido calloso a partir de los brotes de primera generación (R1). Con la concentración de 80 mg/l de 6-BAP, se observó la presencia de plántulas anormales, en mayor proporción en las que provenían de tejido callo

Description
An account of the resource
El objetivo de este estudio fue evaluar in vitro la actividad fijadora de nitrógeno y solubilizadora de fosfato de bacterias endófitas de pasto colosoana (Bothriochloa pertusa). Se colectó la raíz, los tallos y las hojas del pasto en cuatro zonas agroecológicas del municipio de Corozal, Sucre, Colombia, durante el segundo semestre del año 2012. Cada tejido fue sometido a proceso de desinfección superficial. Se aislaron bacterias endófitas en medio de cultivo agar R2A, a partir de cada tejido se determinó la densidad poblacional (UFC/g de tejido), por conteo en superficie; la separación de morfotipos se realizó mediante la forma, color, tamaño y apariencia. La actividad fijadora de nitrógeno y solubilizadora de fosfato se evaluó in vitro sobre medios de cultivos específicos. Todos los resultados obtenidos fueron analizados utilizando el programa estadístico R. Hubo diferencias significativas para densidades poblacional de bacterias con respecto a tejido, con mayores valores en raíz (1,61 x 1010/g raíz), seguida de tallo (7,44 x 109/g tallo) y los valores más bajos se reportaron para hojas (5,42 x 109/g hoja). Se encontró significancia entre la densidad poblacional con relación a los factores de zona, fincas y tipo de tejido analizado. Los resultados de la identificación con kit API20E confirmaron la presencia de las bacterias endófitas Aeromonas salmonicida y Pasteurella pneumotropica con capacidad simultánea de solubilizar fosfatos y fijar nitrógeno.
