Title A name given to the resource ANÁLISE PRELIMINAR DA VULNERABILIDADE E CONTAMINAÇÃO DE ÁREA SOB CULTIVO AGRÍCOLA COM BARRAGEM SUBTERRÂNEA NO SEMI-ÁRIDO Creator An entity primarily responsible for making the resource Suzana Maria Gico Lima Montenegro, Thaísa Alcoforado de Almeida, Teresa Eira Leitão, Abelardo Antônio de Assunção Montenegro Description An account of the resource A agricultura familiar é praticada no semi-árido do Nordeste do Brasil de forma empírica, utilizando escassos recursos hídricos subterrâneos em geral vulneráveis. O objetivo desse trabalho é a investigação preliminar da vulnerabilidade e contaminação de um desses sistemas. A área em estudo está localizada na região semi-árida brasileira, no Estado se Pernambuco. A investigação foi procedida na barragem subterrânea Cafundó II, onde é praticada a agricultura familiar de pequeno porte. A investigação preliminar da vulnerabilidade à contaminação foi efetuada a partir da aplicação do índice de vulnerabilidade GOD. Complementarmente, amostras da água subterrânea de um poço utilizado para irrigação e piezômetro foram coletadas para determinação da concentração iônica, visando avaliar contaminação. Observa-se que a área adjacente à barragem subterrânea de Cafundó II apresenta alta vulnerabilidade à contaminação. A água subterrânea está dentro dos padrões vigentes para a água de consumo humano e cultivo de vegetais de consumo sem cozimento, mas a salinidade supera o limite de tolerância das principais culturas praticadas na área apresentando risco perda de produtividade destas. Os resultados refletem a influência da formação geológica e da prática da irrigação, associada ao uso de agroquímicos.

Title A name given to the resource Reconexión producción-consumo: cambio para la seguridad alimentaria y nutricional y el desarrollo rural. Creator An entity primarily responsible for making the resource Shirley Rodríguez-González, Sergio Schneider, Gabriela Coelho-de-Souza Description An account of the resource El objetivo de este estudio fue analizar la importancia del cambio del sistema alimentario convencional para el logro de la seguridad alimentaria y nutricional y el desarrollo rural. Este texto se dividió en tres secciones. En la primera se caracterizó el sistema alimentario convencional y sus consecuencias, mostrándose la necesidad de un cambio que procure la integración de las dimensiones social, ambiental y de salud. En la segunda parte se abordó el papel del Estado en las intervenciones relacionadas con el sistema de abastecimiento alimentario, las cuales son fundamentales para la construcción de la seguridad alimentaria y nutricional y la activación de procesos en el área rural que favorezcan su desarrollo. Finalmente, se presentó la experiencia de Brasil con el Programa Nacional de Alimentación Escolar, en la cual se realizó una vinculación de los alimentos producidos por los pequeños productores con el programa de alimentación escolar, permitiendo la reconexión de la producción y el consumidor a través de mercados institucionales. Esta vinculación creó incentivos para la seguridad alimentaria y nutricional de los pequeños productores y al mismo tiempo, mejoró la disponibilidad de alimentos de mayor calidad para poblaciones vulnerables y promueve patrones alimentarios que permiten la conservación de la cultura alimentaria.

Title A name given to the resource Soil Management and Efficiency of Rhizobia Strains of Cowpea Vigna unguiculata (L.) Walp. in the Tropics Manejo de Suelo y Eficiencia de Cepas de Rizobio de Frijol Vigna unguiculata (L.) Walp. en los Trópicos Creator An entity primarily responsible for making the resource José Geraldo Donizetti dos Santos, Alana das Chagas Ferreira Aguiar, Edilson Máximo Silva Junior, Danubia Lemes Dadalto, Merijane Rodrigues Sousa, Gustavo Ribeiro Xavier, Emanoel Gomes de Moura Description An account of the resource In the humid tropics, the largest obstacle to the implementation of sustainable farming systems is the reduced efficiency of nutrient use by crops. This study assesses the effectiveness of five selected rhizobia strains in symbiosis with cowpea (Vigna unguiculata (L.) Walp.), with the objective of replacing N fertilization in the predominant agricultural system used by smallholder farmers. The study was carried out in three adjacent areas with distinct agricultural uses: conventional tillage, itinerant agriculture, and a no-till system. The experimental design was in randomized complete blocks with four replicates and seven treatments: five rhizobia strains (BR3262, BR3267, BR3299, INPA3-11B, and UFLA 3-84) and two controls without inoculation (one without mineral N and another fertilized with 74 kg N ha-1). We measured the dry mass of 100 grains, nodules and shoots, as well as cowpea yields and calculated relative and absolute efficiency indices for dry biomass production of cowpea shoots. Agricultural uses affected the number and dry mass of the nodules and, consequently, the mass of the dry plant matter and bean yield. In terms of yield, there was a major difference between the conventional and the itinerant systems. Yield was around four times as high in the itinerant system (1009.9 kg ha-1 compared to 243.7 kg ha-1). Under conditions of cohesion-prone soils, the system of conventional tillage reduces the possibility of cultivation of a second harvest in the year even with inoculation or N fertilization.En los trópicos húmedos, el mayor obstáculo para la aplicación de sistemas de agricultura sostenible es la reducción de la eficiencia del uso de nutrientes por los cultivos. Este estudio evalúa la eficacia de cinco cepas de rizobios seleccionados en simbiosis con frijol (Vigna unguiculata (L.) Walp.), con el objetivo de sustituir la fertilización nitrogenada en el sistema de uso de suelo predominante utilizado por los pequeños agricultores. El estudio se llevó a cabo en tres zonas adyacentes de distintos usos agrícolas: labranza convencional, agricultura itinerante, y un sistema de no laboreo. El diseño experimental fue en bloques al azar con cuatro repeticiones y siete tratamientos: cinco cepas de rizobios (BR3262, BR3267, BR3299, INPA3-11B y UFLA 3-84) y dos controles sin inocular (uno sin N mineral y otro fertilizado con 74 kg de N ha-1). Se midió el peso en seco de 100 granos, de los nódulos y de los brotes, así como los rendimientos de frijol y se calcularon los índices de eficiencia relativa y absoluta para la producción de biomasa seca de los brotes de frijol. El sistema de uso del suelo afecta el número y peso en seco de los nódulos y, en consecuencia, la masa de la materia vegetal seca y el rendimiento del frijol. En términos de rendimiento, hubo una gran diferencia entre el convencional y los sistemas itinerantes. La productividad fue alrededor de cuatro veces mayor en la agricultura itinerante (1009,9 kg ha-1 en comparación con 243,7 kg ha-1). En condiciones de suelos propensos a la cohesión, el sistema de labranza convencional reduce la posibilidad de cultivo de una segunda cosecha en el año, incluso con la inoculación o la fertilización nitrogenada.

Title A name given to the resource Produção de muda de maracujazeiro amarello submetidas ã salinidade em solo como biofertilizante bovino Effect of saline irrigation waters and bovine biofertilizer application on the production of yellow passionfruit seedling Creator An entity primarily responsible for making the resource Lourival Ferreira Cavalcante, Walter Esfrain Pereira, Francisco de Oliveira Mesquita, Járisson Cavalcante Nunes, Alex heus Rebequi, Antonio João De Lima Neto Description An account of the resource O experimento foi desenvolvido em abrigo protegido no período de 1 de maio a 31 de julho de 2008, no município de Areia, estado da Paraíba, PB, Brasil, com objetivo de estudar os efeitos da salinidade da água de irrigação sobre o comportamento inicial de mudas de maracujazeiro amarelo em substrato não salino com e sem biofertilizante bovino. Os tratamentos foram distribuídos no delineamento inteiramente casualizado, com três repetições e doze plantas por parcela, em arranjo fatorial 5 x 2 x 2, referente aos níveis de salinidade da água de irrigação: 0,5; 1,0; 2,0; 3,0 e 4,0 dS m-1, no solo sem e com biofertilizante bovino em duas idades das plantas (25 e 65 dias após a emergência das plântulas). Foram avaliados o crescimento das mudas e a condutividade elétrica do solo ao final do experimento. O biofertilizante foi aplicado, uma única vez, após diluído em água de baixa salinidade na razão de 1:1, dois dias antes da semeadura, ao nível de 10% do volume dos substratos. O aumento da salinidade das águas inibiu o crescimento em altura das mudas, área foliar e comprimento radicular, mas, em qualquer circunstância, com menor intensidade nos tratamentos com o biofertilizante. O aumento da condutividade elétrica da água de irrigação elevou a salinidade do solo, independentemente da adição do biofertilizante.The experiment was conducted in a greenhouse from May 1 to July 31, 2008, in Areia county, Paraiba State, PB, Brazil, in order to evaluate the effects of irrigation water salinity on initial growth of the passionfruit seedlings in non-saline substrate with and without bovine biofertilizer. The treatments were distributed in a completely randomized design, with three replications and twelve plants per plots, in a factorial arrangement 5 x 2 x 2, corresponding the former to the levels of salinity in the irrigation water: 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1, in soils with and without bovine biofertilizer applied at two moments (25 and 65 days after seedling emergence). The growth of the seedlings and the soil electrical conductivity were evaluated at the end of the experiment. The biofertilizer was diluted in a low saline water at a 1:1 ratio and was applied once two days before sowing, corresponding to 10% of the substrates volume. The increase in water salinity inhibited the growth in height of plants, leaf area and root length, but always to a lesser extent in the treatments with bovine biofertilizer. The increase in electrical conductivity of the irrigation water elevated the soil salinity, independently of the addition of biofertilizer.

Title A name given to the resource Análise exploratória da socioeconomia de sistemas agroflorestais em várzea flúvio-marinha, Cametá-Pará, Brasil Exploratory socioeconomic analysis of agroforestry systems in tidal river floodplains, Cametá, Pará, Brazil Creator An entity primarily responsible for making the resource Raimundo Nonato da Silveira Ribeiro, Antônio Cordeiro de Santana, Manoel Malheiros Tourinho Description An account of the resource Este trabalho objetivou identificar e caracterizar o sistema de exploração da várzea flúvio-marinha em unidades de produção agroflorestal - UPA, nos aspectos florísticos e socioeconômicos. Utilizaram-se as técnicas do inventário florestal, orçamentos unitários e questionários. Os resultados expressaram uma composição florística média de 2.920,7 indivíduos/ha com circunferência à altura do peito (CAP)>10 cm, com maiores frequência de açaí (50,63%), cacau (31,02%) e virola (6,76%). O Sistema está constituído pela exploração florestal madeireira, não-madeireira, pesca e criação de aves e suínos. O custo anual do sistema agroflorestal - SAF é de R$ 1.866,25/UPA e a renda bruta anual oriunda do SAF é de R$ 2.959,08/UPA. Concluiu-se que o sistema é do tipo agrossilvipastoril, em que a atividade de criação de aves e suínos utiliza como fonte de alimentos a mariscagem na várzea. A tecnologia utilizada, em princípio, favorece a conservação e preservação do ecossistema, há todavia a necessidade de qualificação de mão-de-obra familiar. A renda bruta anual do SAF denota viabilidade econômica das UPA no nível do salário mínimo, porém, tais unidades são pluriativas, apresentando rendas múltiplas, cujas rendas não-agrícolas são fundamentais para a permanência das famílias na atividade e no meio rural.The purpose of this paper is to identify and characterize forestry and socio-economic systems of tidal river floodplain utilization in agroforestry production units (UPA). Forest inventory techniques, budget sheets and questionnaires were utilized. The results obtained express an average floristic composition of 2,920.7 plants/ha, with a breast-high circumference (CHC)>10cm, the highest frequency being for açaí (Euterpe oleracea) (50.63%), cocoa (Theobroma cacau) (31.02%) and virola (Virola surinamensis) (6.76%). The system comprises timber and non-timber forest exploitation, fishing, and poultry and swine raising. The annual cost of the agroforestry system (SAF) is R$1,866.25/UPA and annual gross income is R$2,959.08/UPA. It was concluded that the system is an agro-silvi-pastoral one, where poultry and swine raising utilizes floodplain shellfish as feed source; in principle, the technology used is favorable to the ecosystem conservation; however, there is a need for improving the quality of family labor. The SAF annual gross income demonstrates the economic feasibility of the UPAs at a minimum wage level; however, such units are multi-functional and have multiple incomes whose non-agricultural earnings are fundamental to families persevering in this activity and staying in the rural environment.

Pérez Díaz, Ana Lucia Vásquez Vela, Agustín Cerna Mendoza, Manuel Santiago Doria Bolaños, Luís Arévalo López, João Luiz Lopes Monteiro Neto, Wilson F Guerra Arévalo, Sara Thiele Moreira Sobral, Carlos Abanto-Rodríguez Description An account of the resource La utilización de extractos vegetales como insecticidas naturales es una alternativa eficiente y ecológicamente viable para el uso directo en el control de plagas. En el estudio se evaluó el efecto de diferentes concentraciones de resina de Jatropha curcas en el control de larvas de Hypsipyla grandella Zéller, para el efecto en un Diseño Completamente al Azar (DCA), en esquema de parcelas subdivididas, se evaluaron cinco tratamientos, en tres repeticiones y 10 discos foliares de S. macrophylla por unidad experimental. Las parcelas principales consistieron en cinco concentraciones (%) de resina de J. curcas: T1:0; T2: 10; T3: 20; T4: 30; y T5: 40 y las subparcelas en los tiempos de evaluación (horas): 6, 12, 18 y 24 en el transcurso del día. Como variables medidas se incluyeron el consumo del disco foliares-CDF (%), el incremento de consumo foliar-ICF (%), la sobrevivencia-SL (%), la mortandad – ML (%), el número de orificios foliares-NOF y actividad larval-AL (%). La resina de J. curcas en concentración de 40% ocasiona en larvas de H. grandella una mortalidad de 67% y una actividad larval < 30%). Los resultados indican que las concentraciones de extracto de J. curcas ocasionaron efectos significativos en todas las variables evaluadas, no obstante, las concentraciones menores fueron menos eficientes en el control de larvas. Se concluye que la resina de J. curcas es un bioinsecticida potencial en el control de larvas de H. grandella presentando los mejores resultados en concentraciones > 30%.

Creator An entity primarily responsible for making the resource José Maria Arcanjo Alves, Ataiza de A. Sousa, Sebastião R. G. da Silva, Guido Nunes Lopes, Oscar José Smiderle, Sadra Cátia Pereira Uchôa Description An account of the resource O pinhão-manso (Jatropha curcas L.), da família Euforbiaceae, é uma espécie que pode ser cultivada em diferentes condições edafoclimáticas. Apresenta valor medicinal, ornamental e na produção de óleo. Atualmente tem aumentado o interesse no conhecimento agronômico desta cultura, visando à seleção e o aprimoramento de variedades mais produtivas e economicamente viáveis, principalmente devido ao alto potencial na produção de óleo para fabricar o biodiesel. Apesar de ainda não ser cultivada comercialmente no Brasil, mostra-se viável para a agricultura familiar das regiões Norte e Nordeste, pois tem alta resistência à seca e boa adaptação as altas temperaturas e insolação, além de produzir em solos ácidos e de baixa fertilidade como os do cerrado da Amazônia. Estudos estão sendo conduzidos com essa cultura no estado de Roraima visando desenvolver tecnologias viáveis de produção para serem adotadas pela agricultura familiar, como uma alternativa promissora na geração de emprego e renda, promovendo a recuperação e proteção de áreas alteradas ou degradadas e permitindo o consórcio com fruteiras nativas e culturas anuais. = The pinhão-manso (Jatropha curcas L.), from the Euforbiaceae famíly, is a species that can be raised in different edafoclimatic conditions. It presents a regular medicinal and ornamental value, and it is also useful for oil production, Nowadays it is increasing the interest in the agronomic knowledge of this culture, mostly related to the selection and improving of more productive and economically feasible varieties, mainly due to its high potencial for biodiesel production. Although this species is not yet cultivated for market use in Brasil, it has shown feasibility for family agriculture in North and Northeast regions, because of its great resistance to draught as well as its good adaptation to high temperatures and insolation. This species can also produce in highly acid and scarcely fertile soils, such as those in the Amazonian savannah. There are various studies in progress dedicated to this culture in Roraima state, and through these studies, it may be achieved a possibility to develop feasible production technologies that could be adopted by family agriculture. That would show a promising alternative for job creation and better income, fostering the recovering and protection of modified areas, and promoting the organization of native fruit and annual cultures consortiums.

ABSTRACT In this paper will be discussed the outcomes from the study of agroecological and organic market agricultural practices conducted in the counties of Dona Francisca, Agudo and Nova Palma, belonging to Quarta Colônia – a region located in the center of the Rio Grande do Sul state in Brazil. The main goal of this work is to analyze the production of organic and agroecological foods in this region, using the qualitative approach to guide the data collection and analysis of the results. The paper is structured in two parts. The first one is composed by the literature review, in which we present and develop the concepts of agroecological, ecological and organic agriculture. The second part addresses the agroecological and organic farming experiences. Both discussions will lead to the disclosure of the final considerations, highlighting their particularities regarding to the rural development at the local / regional level. Keywords: Agroecological Based Agriculture; Organic Agriculture; Quarta Colônia. RESUMEN En este artículo, serán discutidos los resultados en que se refiere al estudio de prácticas agrícolas de base agroecológica y orgánica de mercado, realizado en los municipios de Dona Francisca, Agudo e Nova Palma, pertenecientes a la Quarta Colônia – región ubicada en el centro del Estado de Rio Grande do Sul, en Brasil. Este trabajo tiene como objetivo central el análisis acerca de la producción de alimentos orgánicos y agroecológicos en la región, utilizando el abordaje cualitativo para el direccionamiento de la recolección de datos y del análisis de los resultados. El artículo se estructura en dos partes. La primera está compuesta por la revisión de literatura, en la que presentamos y desarrollamos los conceptos de agricultura agroecológica, ecológica y orgánica. La segunda parte aborda experiencias de agricultura de base agroecológica y orgánica. Ambas discusiones llevarán a la construcción de las consideraciones finales, destacando sus particularidades en relación al desarrollo rural a nivel local / regional.

Title A name given to the resource Ecología trófica del jabalí europeo (Sus scrofa) silvestre en Chile Trophic ecology of the wild boar (Sus scrofa) in Chile Creator An entity primarily responsible for making the resource FABIÁN M. JAKSIC, ÓSCAR SKEWES, ROBERTO RODRÍGUEZ Description An account of the resource Documentamos la dieta del jabalí silvestre en el centro-sur de Chile basados en el examen de 20 estómagos colectados en los faldeos de volcán Mocho-Choshuenco (39°54' S, 72°02' O) y en el Parque Nacional Vicente Pérez Rosales (41°03' S, 71°54' O). La dieta está representada por animales, vegetales y hongos. Entre los vegetales y hongos son consumidas tanto las partes epígeas como hipógeas, lo mismo que frutos y semillas. Hongos y rizomas de Gunnera tinctoria constituyen ítemes vegetales cuantitativamente importantes en la alimentación. El jabalí forrajea en general en ambiente boscoso, pero las especies vegetales más frecuentes en la dieta se encuentran en espacios abiertos o fuera del bosque. El ambiente dominado por Chusquea spp. constituye un importante sitio de alimentación. Los roedores de la familia Muridae dominan entre los animales determinados en la dieta del jabalí. Esta situación, sin embargo, parece obedecer a la ocurrencia de una ratada producto de la semillación masiva de Chusquea spp. durante la época de muestreo. Las aves de la familia Rhinocryptidae e invertebrados (en especial larvas del coleóptero Chiasognathus grantii) constituyen parte frecuente de los ítemes animales de la dieta del jabalí. En comparación a estudios en otras partes del mundo, el jabalí silvestre en Chile consume hongos en porcentaje de ocurrencia similar (65 %) a su dieta en Estados Unidos de América pero bastante más alta que su dieta en Europa (5-32 %). En relación al volumen del componente animal, el jabalí en Chile consume más (16,1 %) que en Estados Unidos de América (6 %) y que en Europa (7-13 %)We document the diet of wild boar in south-central Chile based on analysis of 20 stomachs collected on the outskirts of Mocho-Choshuenco volcano (39°54' S, 72°02' W) and of Vicente Pérez Rosales National Park (41°03' S, 71°54' W). The diet incorporates animals, plants and fungi. Among the latter two, both epigeal and hypogeal parts are consumed, together with fruits and seeds. Fungi and rhizomes of Gunnera tinctoria are the most abundant plant items in the diet. The wild boar in Chile forages chiefly in forested environments, but nonetheless the most frequent plant items in its diet are found in open spaces or outside the forest. Environments dominated by bamboos Chusquea spp. constitute important foraging sites. Rodents in the family Muridae prevail among animal items in the wild boar diet. This situation, however, is associated to the occurrence of a mouse outbreak (ratada) resulting from the mast seeding of Chusquea spp. during our study. Birds in the family Rhinocryptidae together with invertebrates (specially Coleopteran larvae of Chiasognathus grantii) made up a sizeable part of the animals in the wild boar diet. In comparison to elsewhere, the wild boar in Chile consumes fungi in a similar percentage of occurence (65 %) as in the United States of America but much higher than in Europe (5-32 %). With regard to the animal component, the wild boar in Chile consumes more (20 % volume) of such items than in the United States of America (6 %) and in Europe (7-13 %) Date A point or period of time associated with an event in the lifecycle of the resource 2007 Subject The topic of the resource South America, Sudamérica, bosque templado, especie invasora, invasive species, mast seeding, mouse outbreak, ratada, semillación masiva, temperate forest Source A related resource from which the described resource is derived Revista Chilena de Historia Natural Publisher An entity responsible for making the resource available BMC 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, Zoology Relation A related resource <a href="http://www.scielo.cl/scielo.php?script=sci_arttext&amp;pid=S0716-078X2007000300004" target="_blank" rel="noreferrer noopener">http://www.scielo.cl/scielo.php?script=sci_arttext&amp;pid=S0716-078X2007000300004</a> https://www.socictopen.socict.org/files/original/171d617887d777ab062031ab6234cee5.pdf f1541a353b637f4d847870c6cc6edb01 Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource Dosis y frecuencia de biofertilizantes en Cucumis sativus L. Municipio de Siuna RACCN Nicaragua Creator An entity primarily responsible for making the resource Jamil Castillo Martínez, Oscar Moltalván Castellón Description An account of the resource La aplicación de abonos orgánicos en la producción agrícola, ha constituido especial importancia desde la percepción de calidad, inocuidad y medio ambiente, en el municipio de Siuna, ya que se han realizado estudios sobre el efecto de los abonos orgánicos; sin embargo, no se han hecho estudios en la zona que evalúen las cantidades y frecuencias de los fertilizantes orgánicos especialmente los foliares.Esta investigación evalúa los efectos de las dosis y frecuencias de aplicación de biofertilizante en el cultivo de Cucumis sativa L, desde su crecimiento, desarrollo y productividad, con la finalidad de evaluar con más detalle el comportamiento de cultivo, y poder recomendar de manera confiable cómo se pueden obtener máximos rendimientos a menores costos y sin afectar el medio ambiente. Es una investigación experimental en el nivel explicativa, se utilizó un diseño completamente aleatorio con tres replicas y un modelo estadístico donde se analizaron cada uno de los tratamientos.Los principales resultados son: El crecimiento y desarrollo en el cultivo del pepino son similares en los diferentes niveles de concentración y aplicación del fertilizante, hay una mejor respuesta a una menor frecuencia y mayor dosis de aplicación del biofertilizante en el número de flores producidas por plantas y la producción de pepino es mayor con menor frecuencias y mayores concentraciones de fertilizante, y que por lo tanto también son más rentables Date A point or period of time associated with an event in the lifecycle of the resource 2019 Subject The topic of the resource CRECIMIENTO Y DESARROLLO, Productividad, inocuidad, rentabilidad Identifier An unambiguous reference to the resource within a given context 10.5377/ruc.v21i2.7767 Source A related resource from which the described resource is derived Revista Universitaria del Caribe Publisher An entity responsible for making the resource available Universidad de las Regiones Autónomas de la Costa Caribe Nicaragüense Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Environmental sciences, Social sciences (General), Education (General) Relation A related resource <a href="http://revistas.uraccan.edu.ni/index.php/Caribe/article/view/575" target="_blank" rel="noreferrer noopener">http://revistas.uraccan.edu.ni/index.php/Caribe/article/view/575</a>
