Title A name given to the resource Substratos e doses de biofertilizante bovino na produção de mudas de aceroleira Creator An entity primarily responsible for making the resource Kássio Alves Dantas, Tamires da Costa Figueiredo, Evandro Franklin de Mesquita, Francisco Vanies da Silva Sá, Nubia Mariza Ferreira Description An account of the resource Objetivou-se avaliar os efeitos de diferentes composições de substratos e níveis percentuais de biofertilizante bovino fornecido ao solo, para a produção de mudas de acerola. O experimento foi conduzido no período de 29 de março a 09 de junho de 2012, em viveiro de produção de mudas do Campus IV da Universidade Estadual da Paraíba, Catolé do Rocha-PB. Foi utilizado o delineamento experimental em blocos casualizados, empregando o esquema fatorial 4 x 2, distribuídos em três blocos, sendo três plantas por parcela, totalizando 72 unidades experimentais, referentes aos níveis de biofertilizantes (0,0; 4,0; 8,0 e 12,0% volume) e dois substratos S1 = (50% areia, 25% solo, 25% esterco bovino); S2= (50% esterco bovino, 25% areia, 25% solo). A aplicação do biofertilizante foi feita em fundação, 24 horas antes do semeio e uma de cobertura aos 32 DAS (dias após a semeadura). A adubação orgânica com biofertilizante, independentemente dos substratos, influencia positivamente o crescimento e acúmulo de matéria seca das mudas de aceroleira. A adição de biofertilizante bovino até 7,15% em volume, independentemente do substrato utilizado, proporcionou mudas de boa qualidade.

Title A name given to the resource Perfil social e percepção de feirantes sobre agricultura de base orgânica e agroecológica Creator An entity primarily responsible for making the resource João Manoel da Silva, Tania Marta Carvalho dos Santos, Luanna Cabral de Almeida, Sheylla Patrícia Gomes do Nascimento, Romário Guimarães Verçosa de Araújo, Clayton dos Santos Silva, Jessé Rafael Bento de Lima, Crisea Cristina Nascimento de Cristo, Jakes Halan de Queiroz Costa Description An account of the resource RESUMO: A busca por alimentos mais saudáveis e melhoria na saúde vem trazendo à população, a procura por alimentos orgânicos, porém, ainda há dúvidas e desconhecimentos acerca de suas concepções. Por outro lado, há a vertente social da produção agroecológica. Essas duas tentem a confundir a população, onde a mesma crê nas duas como uma só. Cada uma com suas peculiaridades. Diante disso, objetivou-se por meio desse estudo conhecer a percepção de feirantes sobre agricultura de base orgânica e agroecológica em feira livre de duas cidades alagoanas. Para tanto, foi adotado um questionário preestabelecido. Com os dados coletados, foi realizada a tabulação dos mesmos e os dados foram expressos em porcentagem sobre a amostragem total. Ao se analisar os valores e as respostas dos entrevistados, observa-se a forte presença do gênero feminino e de pessoas acima dos 40 anos. União dos Palmares possui feirantes com menores níveis de escolaridade. A percepção mostra que a maioria dos feirantes não possui esclarecimento acerca da diferença entre essas duas bases, além de não conhecer suas definições. Quanto á comparação entre as duas cidades, nota-se que as diferenças encontradas são características quando se avalia o perfil social dos entrevistados, onde a percepção não possui diferenças relevantes.    Palavras-chave: feira livre, agroecologia, agricultura orgânica, qualidade alimentar, rurbanidade Date A point or period of time associated with an event in the lifecycle of the resource 2018 Identifier An unambiguous reference to the resource within a given context 10.28998/rca.v16i0.6591 Source A related resource from which the described resource is derived Ciência Agrícola Publisher An entity responsible for making the resource available Universidade Federal de Alagoas Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Agriculture (General), Plant culture, Forestry Relation A related resource <a href="http://www.seer.ufal.br/index.php/revistacienciaagricola/article/view/6591" target="_blank" rel="noreferrer noopener">http://www.seer.ufal.br/index.php/revistacienciaagricola/article/view/6591</a> https://www.socictopen.socict.org/files/original/3460bc6f2cf4a6a48ba991e1e43f830d.pdf 69c4a81ac8232604077978fd398ca895 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 A Competitividade da Cadeia Produtiva de Orgânicos para Agricultura Familiar Creator An entity primarily responsible for making the resource Caroline Sales Arruda, Tiago Ricardo Ribeiro, Diana Marques dos Anjos Description An account of the resource Os anos 70 foram marcados pelo processo de modernização da agricultura, da transformação do complexo rural no chamado Complexo agroindustrial. Atividades como a agricultura orgânica apresentam-se como crescente tendência em alguns países, inclusive no Brasil, sendo a agricultura familiar responsável por grande parte da produção. No entanto, a competitividade da cadeia produtiva de produtos orgânicos fundamenta-se em estratégias de diferenciação de produtos e o grande desafio consiste na capacidade de criação, principalmente, de um ambiente institucional que possibilite melhor coordenação entre os agentes e, conseqüente ganho de competitividade para a cadeia. O presente trabalho visa analisar este ambiente e outros fatores que de forma direta ou indireta afetam a competitividade da cadeia produtiva de orgânicos, por meio do paradigma clássico proposto pela economia industrial. Em primeiro instante este aborda breve contexto sobre cadeia de produção e conceitos sobre competitividade, seguido por discussão acerca da cadeia produtiva a fim de analisar a competitividade da mesma no setor em questão.

Title A name given to the resource Salt stress in cowpea plants on biofertilized soil = Estresse salino em plantas de feijão-caupi em solo com fertilizantes orgânicos. Creator An entity primarily responsible for making the resource Geocleber Gomes de Sousa, Thales Vinícius de Araújo Viana, Claudivan Feitosa de Lacerda, Benito Moreira de Azevedo, Giovana Lopes da Silva, Fellype Rodrigo Barroso Costa Description An account of the resource The use of organic fertilizer from animal waste can mitigate the harmful effects of salinity of irrigation water on the plants. This experiment was performed in the experimental area of the Universidade Federal do Ceará, Weather Station (EstaçãoMeteorológica), from September to November 2012, aiming at evaluate the response of the cowpea (Vigna unguiculata L.)to salinity levels and biofertilizer types in a greenhouse. The experimental design was that of completely randomized, 5x3factorialwith five replications. The first factor consisted of electrical conductivity of irrigation water levels, as follows: 0.8 dS m-1; 1.5 dS m-1; 3.0 dS m-1; 4.5 dS m-1 and 6.0 dS m-1; and the second factor comprised three conditions: without biofertilizers (B0), with enriched crabbio fertilizer (B1) and with bovine common biofertilizer (B3). The evaluated variables were: photosynthesis, leaf temperature, transpiration, stomatal conductance, plant height, stem diameter, number of leaves, leaf area, and shoot dry mass. The crab enriched biofertilizer more efficiently mitigates the salt stress on plant height, stem diameter, number of leaves, leaf area, photosynthesis, transpiration and stomatal conductance of cowpea cultivar BRS ITAIM compared to plants with biofertilizer and biofertilizer bovine common. The biofertilizer of crab enriched more efficiently mitigates the salt stress on plant height, stem diameter, number of leaves, leaf area, photosynthesis, transpiration and stomatal conductance of cowpea cultivar BRS ITAIM compared to plants without biofertilizer and bovine common biofertilizer. = O uso de fertilizantes orgânicos provenientes de resíduos de origem animal pode atenuar os efeitos danosos da salinidade da água de irrigação sobre as plantas.

Title A name given to the resource Effect of Compost Application on Some Properties of a Volcanic Soil from Central South Chile Efecto de la Aplicación de Compost sobre Algunas Propiedades de un Suelo Volcánico de La Región Centro-Sur de Chile Creator An entity primarily responsible for making the resource Pedro José Valarini, Gustavo Curaqueo, Alex Seguel, Karina Manzano, Rosa Rubio, Pablo Cornejo, Fernando Borie Description An account of the resource Soil compost application is a common soil management practice used by small farmers of Central-South Chile that produces positive effects on soil properties and also promotes presence and activity of arbuscular mycorrhizal fungi (AMF). This fungi form symbiosis with plant roots improving plant nutrition, as well as producing glomalin, a glycoprotein that has been associated with soil aggregation stability. Therefore, the aim of this study was to evaluate, in an Ultisol from Central-South Chile, the effect of different doses of compost on some soil characteristics at the end of the third year of a crop sequence including wheat (Triticum aestivum L.), bean (Phaseolus vulgaris L.), and grassland (Lolium multiflorum Lam. associated with Trifolium repens L.). Studied soil characteristics included chemical (pH, available-P, organic C), biological (C and N biomass, AMF spore number, root colonization percentage, mycelium length, and glomalin content), as well as physical parameters (water holding capacity [WHC], and water stable aggregates [WSA]). Results showed that, in general, compost application increased soil pH, mycorrizal roots, mycelium length, glomalin levels, and WSA. Significant relationships were found between C and N biomass, C biomass and WSA, C biomass and glomalin, WSA and WHC, among others. Results suggest that compost application to this type of soil is a feasible option as a fertilizer substitute, and a way to avoid soil erosion by small local farmers involved in organic agriculture.La aplicación de compost al suelo, práctica habitual en predios de pequeños agricultores de la región centro-sur de Chile, produce efectos positivos en sus propiedades y promueve la presencia y actividad de los hongos micorrícicos arbusculares (AMF). Estos hongos forman simbiosis con las raíces de las plantas mejorando su nutrición y además producen una glicoproteína llamada glomalina, la cual ha sido relacionada con la estabilidad de los agregados de suelo. Por lo anterior, el objetivo de este estudio fue evaluar el efecto de la aplicación de distintas dosis de compost sobre algunos parámetros de un Ultisol de la zona centro-sur de Chile, al finalizar el tercer año de una secuencia de cultivos formada por trigo (Triticum aestivum L.), frejol (Phaseolus vulgaris L.) y pradera permanente (Lolium multiflorum Lam. asociada con Trifolium repens L.). Se estudiaron parámetros químicos (pH, C orgánico, P-Olsen), biológicos (C y N biomásico, número de esporas de AMF, micorrización de raíces, longitud de micelio y niveles de glomalina), y físicos (capacidad de retención de agua, WHC, y agregados estables al agua, WSA). Los resultados mostraron que, en general, la aplicación de compost incrementó el pH, micorrización radical, niveles de glomalina, longitud del micelio fúngico y porcentaje de WSA. Se encontraron correlaciones entre C y N biomásico, C biomásico y WSA, C biomásico y glomalina, WSA y WHC. Los resultados aportan antecedentes sobre el uso beneficioso de compost como una alternativa viable de sustitución de insumos y disminución de la erosión en asentamientos de pequeños agricultores orientados a la agricultura orgánica.

Title A name given to the resource Euglossine bees as potential bio-indicators of coffee farmas: Does forest access, on a seasonal basis, affect sbundance? Creator An entity primarily responsible for making the resource Ingemar Hedström, Jessica Harris, Kimberly Fergus Description An account of the resource In order to understand the implications of agriculture on the environment, ecosystem health must be measured. Observing the presence of a biological indicator within an ecosystem is one such method. In this study, male euglossine bees were observed using as attractant cineole 1:8, at adjacent organic (La Paz) and conventional (La Carena) coffee farms near the Northern Barranca River, San Ramón, Alajuela, Costa Rica. Simultaneous data collections were conducted on both farms in April 2004 (late-dry season) and June 2004 (early-rainy season) and combined with the findings of August 2004 (mid-rainy season). These observations show that orchid bees are a viable bio-indicator of organic farm health on a seasonal basis. In the dry season there was no significant difference in orchid bee abundance between the two farms. There is a strong tendency for more bees during the rainy season, suggesting that orchid bee abundance is linked to seasonality and forest access. Rev. Biol. Trop. 54 (4): 1189-1195.

Title A name given to the resource Estimating evaporation with thermal UAV data and two-source energy balance models Creator An entity primarily responsible for making the resource H. Hoffmann, H. Nieto, R. Jensen, R. Guzinski, P. Zarco-Tejada, T. Friborg Description An account of the resource Estimating evaporation is important when managing water resources and cultivating crops. Evaporation can be estimated using land surface heat flux models and remotely sensed land surface temperatures (LST), which have recently become obtainable in very high resolution using lightweight thermal cameras and Unmanned Aerial Vehicles (UAVs). In this study a thermal camera was mounted on a UAV and applied into the field of heat fluxes and hydrology by concatenating thermal images into mosaics of LST and using these as input for the two-source energy balance (TSEB) modelling scheme. Thermal images are obtained with a fixed-wing UAV overflying a barley field in western Denmark during the growing season of 2014 and a spatial resolution of 0.20 m is obtained in final LST mosaics. Two models are used: the original TSEB model (TSEB-PT) and a dual-temperature-difference (DTD) model. In contrast to the TSEB-PT model, the DTD model accounts for the bias that is likely present in remotely sensed LST. TSEB-PT and DTD have already been well tested, however only during sunny weather conditions and with satellite images serving as thermal input. The aim of this study is to assess whether a lightweight thermal camera mounted on a UAV is able to provide data of sufficient quality to constitute as model input and thus attain accurate and high spatial and temporal resolution surface energy heat fluxes, with special focus on latent heat flux (evaporation). Furthermore, this study evaluates the performance of the TSEB scheme during cloudy and overcast weather conditions, which is feasible due to the low data retrieval altitude (due to low UAV flying altitude) compared to satellite thermal data that are only available during clear-sky conditions. TSEB-PT and DTD fluxes are compared and validated against eddy covariance measurements and the comparison shows that both TSEB-PT and DTD simulations are in good agreement with eddy covariance measurements, with DTD obtaining the best results. The DTD model provides results comparable to studies estimating evaporation with similar experimental setups, but with LST retrieved from satellites instead of a UAV. Further, systematic irrigation patterns on the barley field provide confidence in the veracity of the spatially distributed evaporation revealed by model output maps. Lastly, this study outlines and discusses the thermal UAV image processing that results in mosaics suited for model input. This study shows that the UAV platform and the lightweight thermal camera provide high spatial and temporal resolution data valid for model input and for other potential applications requiring high-resolution and consistent LST.
