| Certified organic production by small-scale farmers in developing countries is increasingly promoted as an opportunity to access a growing and dynamic market, while at the same time, enhance productivity and improve incomes. Nevertheless, adoption has been limited. The economics literature suggests profitability is the main constraint, however, the sustainable agriculture literature is inconclusive and considers attitudes of significant importance. Using the Theory of Planned Behaviour, this study investigates the psychological barriers to adoption using small-scale avocado producers from Michoacan, Mexico as a case study. The data is obtained from a household study carried out during 2004 and is modelled using an ordered probit model. Despite positive... |

| Este estudo teve como objetivo avaliar a produção de massa fresca de alface, rúcula e manjericão consorciados, sombreados ou não, com e sem adubação orgânica, em sistema de transição agroecológica no Assentamento 72, Ladário-MS. Os tratamentos foram: T1 - sem sombreamento e com adubação orgânica; T2 - sem sombreamento e sem adubação orgânica; T3 - com sombrite 50% e com adubação orgânica; T4 - com sombrite 50% e sem adubação orgânica. O tratamento sem a cobertura do sombrite e com adubação orgânica de esterco bovino proporcionou maiores resultados de massa fresca para a alface, rúcula e manjericão consorciados, propiciando ao agricultor maior renda numa mesma área cultivada. The aim of this study was evaluate the fresh mass of lettuce, arugula and basil... |

| Studies with botanical insecticides have become more popular as an alternative to Integrated Pest Management. The purpose of this study was to evaluate the effect of leaf and fruit aqueous extracts, from the species Clibadium sylvestre, and leaves and root of Derris amazonica species at concentrations of 0, 1, 2, 4 and 8%, in the control of the aphid Myzus persicae (Hemiptera: Aphididae). Four experiments were conducted; two tests with choice preference and two tests with no choice preference, giving nine treatments and five repetitions. Phytochemical screening was carried out from the leaves and fruit of the species C. sylvestre and leaves and root of D. amazonica. Evaluations of mortality, number of nymphs, and deterrence index of the insects were... |

| Snap bean is a species widely cultivated in Goiás, in which cultivars of indeterminate growth are used in a staking system. Considering the high cost of staking and the unavailability of a workforce, there has been a demand for bush cultivars, but little is available on the market. In this sense, the present study was developed to evaluate, in 2016, under the conventional and organic cultivation systems, in Anápolis-GO, the behavior of 20 bush snap bean genotypes. The experimental design was randomized blocks, with 20 treatments and three replications. There was a significant interaction between genotypes and cultivation systems for vigor, average pod mass, number of pods per plant, and pod yield, evidencing that the types of cultivation, organic and... |

| ABSTRACT This study was carried out to evaluate the contributions to the optimization of water use in a carrot crop under different forms of mulch using Gliricidia sepium, fertilization with castor bean cakes and irrigation water depths. The experiment was conducted in Seropédica, RJ, Brazil (22º 46’ S and 43º 41’ W), from June to September 2010. The experiment was conducted using a split-split-plot scheme (5 x 3 x 2), with four replicates. The five plots had irrigation depths corresponding to 0, 43, 72, 100 and 120% of crop evapotranspiration (ETc); the three subplots contained the different forms of mulch (whole leaves (WL) and chopped leaves and branches (CLB)) and the absence of mulch (AM); and the two sub-subplots contained either the presence (PF) or... |

| ABSTRACT The objective of this work was to evaluate the quality of chicory seedlings in organic substrata and their influence on yield and commercial yield in a protected environment and under direct sunlight. Seedling and field production experiments were conducted in a randomized block design with four blocks. In the first experiment, seedlings were produced on substrata by alternating the conditioner: 1) dry coconut fiber + blend (soil, organic compost, charcoal); 2) carbonized rice husk + blend; 3) crushed ouricuri stem + blend; 4) decomposed kapok stem + blend and 5) commercial substratum. Sufficient seedlings were produced for the evaluations and transplantation. In the field phase, two experiments were evaluated, one in a protected environment and... |

| Este artigo analisa o processo de implantação da agricultura orgânica em assentamentos de reforma agrária, ainda recente no Brasil, e que trouxe consigo uma rápida transformação para a agricultura familiar. Procura analisar a contribuição da agricultura orgânica como alternativa de sustentabilidade sócio- econômica e ambiental da produção e entender o processo de reforma agrária brasileira e suas dificuldades, mostrando os possíveis caminhos para o agricultor assentado agregar valor à produção e se inserir em uma economia de mercado. Além do que, analisa os impactos identificados na elevação da renda familiar e melhoria nas condições de vida. Procurou-se analisar o caso do assentamento Ronda/Chico Mendes, no município de Pombos, em Pernambuco. A pesquisa... |

| The perfect segregation of the different agricultural production types, namely conventional, organic or based on genetically modified organisms is not possible in practice. But the side by side functioning of this systems in agricultural production and further on of the products on the shelves requires suitable measures during cultivation, harvest, transport, storage, and processing to ensure co-existence. Consumers, food and feed industry, as well as wholesalers and retailers in European Union, including Polish ones demand a reasonable degree of choice between GMO and non-GMO derived products. Accordingly the ability to maintain different agricultural production and processing systems is a pre-requisite for providing a high degree of consumer choice. As... |

| Resumo: Apesar de o modelo agrícola convencional ou industrial ter proporcionado aumentos significativos de produtividade dos cultivos e formado sistemas "aparentemente" rentáveis, tem sido severamente questionado por estar associado a uma série de problemas ecológicos e socioambientais. As agriculturas tidas como alternativas ao modelo convencional são consideradas com potencial para contribuir e enfrentar esses problemas. Entre elas estão aquelas relacionados à segurança alimentar e à preservação do meio am biente, tais como a Agroecologia (AE) e Agricultura Orgânica (AO). Para além de objetivos comuns, ambas (AE) e (AO) se referem à ecologia e questionam o modelo tecnológico implantado durante o século XX. |

| Environmental and social justifications for organic conversion subsidies are as pervasive in the United States as in Europe, but national policy does not explicitly support organic agriculture. Using Sweden's experience, we analyze factors that affect whether a subsidy is required to motivate organic conversion. We use a utility difference model to compare farmers who converted before and after the subsidy. Significant factors in conversion without subsidies are greater livestock diversity and more sales outlets. Farmers requiring subsidies manage larger farms, are more concerned with organic inspection quality and adequacy of technical advice, and reside in areas with more organic farms. Results suggest that a subsidy induces mainly those already... |
