El artículo describe el trabajo simbólico llevado a cabo por las agencias de desarrollo rural y las organizaciones agrarias en la provincia de Misiones en la década de 1990. Se consideran las publicaciones destinadas a los pequeños productores y las formas de apropiación de los textos a partir de conceptos de la historia cultural. Los impresos analizados ponen en juego distintas representaciones de la agricultura familiar, especialmente las nuevas categorías agrarias que se difunden en la provincia (campesinos, mujeres rurales, agricultores sin tierra). La producción de los textos se organiza de acuerdo a las dimensiones que estructuran el campo del desarrollo rural: saberes nativos versus transferencia tecnológica; integración agroindustrial versus autonomía campesina; agricultura industrial versus agroecología, etc.This article describes the symbolic work carried out by the agencies of rural development and the agrarian organizations in the province of Misiones in the decade of 1990.

Description
An account of the resource
Estimating crop nitrogen (N) status with sensors can be useful to adjust fertilizer levels to crop requirements, reducing farmers’ costs and N losses to the environment. In this study, we evaluated the potential of hyperspectral indices obtained from field data and airborne imagery for developing N fertilizer recommendations in maize (Zea mays L.). Measurements were taken in a randomized field experiment with six N fertilizer rates ranging from zero to 200 kg∙N∙ha−1 and four replications on two different dates (before the second fertilizer application and at flowering) in 2012. Readings at ground level were taken with SPAD®, Dualex® and Multiplex® sensors, and airborne data were acquired by flying a hyperspectral and a thermal sensor 300 m over the experimental site. The hyperspectral imagery was used to calculate greenness, chlorophyll and photochemical indices for each plot. The Pearson coefficient was used to quantify the correlation between sensor readings and agronomic measurements. A statistical procedure based on the N-sufficient index was used to determine the accuracy of each index at distinguishing between N-deficient and N-sufficient plots. Indices based on airborne measurements were found to be as reliable as measurements taken with ground-level equipment at assessing crop N status and predicting yield at flowering. At stem elongation, the reflectance ratio, R750/R710, and fluorescence retrieval (SIF760) were the only indices that yielded significant results when compared to crop yield. Field-level SPAD readings, the airborne R750/R710 index and SIF760 had the lowest error rates when distinguishing N-sufficient from N-deficient treatments, but error reduction is still recommended before commercial field application.

Description
An account of the resource
The antifungal protein (AFP) produced by Aspergillus giganteus, encoded by the afp gene, has been used to confer resistance against a broad range of fungal pathogens in several crops. In this research, transgenic olive plants expressing the afp gene under the control of the constitutive promoter CaMV35S were generated and their disease response against two root infecting fungal pathogens, Verticillium dahliae and Rosellinia necatrix, was evaluated. Embryogenic cultures derived from a mature zygotic embryo of cv. ‘Picual’ were used for A. tumefaciens transformation. Five independent transgenic lines were obtained, showing a variable level of afp expression in leaves and roots. None of these transgenic lines showed enhanced resistance to Verticillium wilt. However, some of the lines displayed a degree of incomplete resistance to white root rot caused by R. necatrix compared with disease reaction of non-transformed plants or transgenic plants expressing only the GUS gene. The level of resistance to this pathogen correlated with that of the afp expression in root and leaves. Our results indicate that the afp gene can be useful for enhanced partial resistance to R. necatrix in olive, but this gene does not protect against V. dahliae.

An account of the resource
Objetivou-se avaliar neste trabalho a influência da variabilidade climática sobre a pluviometria local e, consequentemente sobre a produção agrícola, sobretudo das culturas de milho, feijão e mandioca, responsáveis pelas maiores atuações na renda dos agricultores familiares de Aiuaba (CE). Os resultados das Análises de Ondeletas apontaram ciclos de 5-6 anos (ENOS) para ocorrência de anos chuvosos, consequência da associação de diferentes escalas temporais, enquanto que em anos secos foram observados ciclos entre 4 e 6 anos (ENOS), mostrando que a escala de ENOS influencia em toda série de precipitação. Na falta de associação com as demais escalas temporais ocorreram anos secos. Correlações entre precipitação e todas as variáveis de produção apresentaram-se altas e com significância estatística, manifestando menores correlações apenas entre precipitação e área planta e colhida para a cultura da mandioca, únicas variáveis sem significância estatística. O presente estudo mostrou que as informações geradas para o município são proveitosas para os diversos setores como agrícola e socioeconômico. Notou-se também que a variabilidade climática tem efeitos substanciais na produção da agricultura familiar local. A B S T R A C T In semi-arid regions such as the county of Aiuaba (CE) the agricultural productivity is more likely to be influenced by edaphoclimatic factors, what beyond of the importance of the producer’s technological level, also influence directly in agriculture. The objective this work was to evaluate the influence of climate variability on the local rainfall and consequently on agricultural production, especially of maize, beans and cassava, account for the greatest performances in the income of farmers of Aiuaba (CE). To reach these objectives were used statistical methods as Correlation and Analysis of Wavelet. The results of the Wavelet analysis pointed cycles of 5-6 years (ENSO) for the occurrence of rainy years, a consequence of several different temporal scales, while in dry years were observed cycles between 4 and 6 years (ENSO), showing that the ENSO scale influence on all series of rainfall. In the absence of association with other timescales occurred dry years. Correlations between rainfall and all production variables were high and with statistical significance, showing only small correlations between rainfall and plant and harvested area for cassava, only variables not statistically significant. This study showed that the information generated for the city are useful for various industries like agriculture and socioeconomic. It was also noted that climate variability has significant effects on the production of local family farmers. Keywords: Climate variability, Family farming, Correlation, Wavelets, ENSO.

Márcia Varela Silva, Mayron Augusto Borges de Oliveira
Description
An account of the resource
O sistema de produção orgânico visa a produção de alimentos ecologicamente sustentáveis, economicamente viáveis e socialmente justos, capaz de integrar o homem ao meio ambiente. A adoção desse sistema de produção vem crescendo, tanto em área cultivada como em número de produtores e mercado consumidor, embora ainda represente uma parcela pequena da agricultura. O crescimento da agricultura orgânica se deve ao fato da agricultura convencional basear-se na utilização intensiva de produtos químicos, fazendo com que os consumidores vejam neste sistema de produção uma possibilidade de risco à saúde e ao meio ambiente, buscando produtos isentos de contaminação. Com isso, a agricultura orgânica tem se destacado como uma das alternativas de renda para os pequenos agricultores, devido à crescente demanda mundial por alimentos mais saudáveis. Os produtos orgânicos não usam agrotóxicos, são obtidos em sistemas sustentáveis, pois mantêm os recursos naturais e a fertilidade do solo, e têm qualidade garantida por certificadoras. A agricultura orgânica considera a propriedade agrícola como uma unidade, como um organismo, onde o solo, a planta, o animal e o homem interagem harmoniosamente com o meio ambiente, demonstrando vantagens econômicas, sociais e ambientais dos sistemas de produção orgânico, tendo sempre em foco a importância da certificação desses produtos de origem orgânica, que é um elemento importante para o direcionamento do sistema de produção orgânica. A certificação orgânica padroniza e facilita a comunicação entre os agentes responsáveis pelo processo de produção e o seu consumidor, promovendo a transparência dos atributos intrínsecos relevantes do produto para o consumidor, que busca um produto de qualidade superior ao convencional, possibilitando a utilização do selo fornecido pelas certificadoras, que é a garantia que o consumidor tem de estar consumindo produtos orgânicos. Afinal, com o crescente interesse pela agricultura orgânica, surge a necessidade de uma verificação segura, que garanta ao consumidor a certeza de estar adquirindo produtos orgânicos. O objetivo deste trabalho é a realização de uma abordagem sobre a situação atual do processo de certificação orgânica no Brasil.

A bioética ambiental, entendida como hermenêutica crítica, pode contribuir significativamente na discussão sobre as causas da crise ecológica e os parâmetros necessários para uma sustentabilidade socioambiental. Dois âmbitos da sociedade atual são centrais para essa questão: o modo como funciona a economia e a agricultura. A equação que rege o modelo de economia pelo consumo e que determina o tipo de agricultura pela química constituem processos produtivos que são ambientalmente suicidas, porque não respeitam os princípios básicos de funcionamento da natureza: ecocentrismo, entropia, trofobiose/homeostase. Por isso esses princípios precisam tornar-se parâmetros para definir e alcançar a sustentabilidade socioambiental.

An account of the resource
Se comparó el efecto en la fertilidad del suelo y en la producción de fríjol (Phaseolus vulgaris) x millo (Sorghum sp.) de sistemas parciales de agricultura biológica y convencional (local), durante 3 semestres (1995A-1996A), utilizando un arreglo de parcelas divididas y un diseño en bloques completos al azar con 3 replicaciones, en el que la Parcela Mayor fue el tipo de manejo de plagas (biológico o químico), la Subparcela fue el arreglo de cultivo (asocio vs cultivo) y la Sub-subparcela fue el tipo de fertilización química vs abonamiento orgánico. En ninguno de los tres semestres se presentaron diferencias significativas entre los rendimientos de fríjol por efecto de los tipos de agricultura, confirmando resultados anteriores de 1994A y B. Durante 1995B, los rendimientos del millo fueron significativamente superiores en el sistema biológico, debido probablemente, a efectos edáficos. Los Indices de Uso Eficiente de la Tierra (IET) fueron superiores a 1 en toda la experiencia, indicando el efecto positivo del asocio. Se constataron incrementos en acidez, capacidad de intercambio catiónico, bases totales y saturación total del suelo en todas las parcelas, que incidieron para que su fertilidad global aumentara de baja a moderada.<br />The effects of organic versus conventional farming methods in soil fertility and intercropping yields (Phaseolus vulgaris x Sorghum sp.) was studied throughout three growing seasons (1995A-1996A). The methodoly used to conduct the study was to divide the field into parcels, aplying natural vs chemical disease controls, monoculture vs intercropping and manure vs chemical fertilizers. As well as other experience carried out in 1994, neither bean growing season presented significant differences between the two agricultural systems, although the yield of sorghum in the organic farming system was superior to that of the conventional system during 1995B, probably due to edaphic effects. The Efficient Land Use Index<br />(IET) were superior to 1 during all over the experience, showing the benefits of the intrercropping systems. There was increases on pH, exchangecationiccapacity,totalcations and total soil saturation that also increasedsoil fertility from lower to medium levels in both organical and conventional systems.<br />
