Description
An account of the resource
A survey was done based on 19 goat shepherds at counties of Centre-highlands, Northern and North-western regions of the Rio de Janeiro State and at the county of Pedra Dourada, Zona da Mata region, State of Minas Gerais. We aimed to characterise the primary sector of the goat milk production chain settled at those regions. Therefore, questionnaires were applied in order to depict profiles of the shepherds, their families, the role of the wife in the activity, the resources available, dependence on income generated by the activity, and how producers administrate their business. Farms were distributed in five strata according to the following daily milk production averages and standard deviations: 8.8 ± 0.9, 15.7 ± 3.9, 22.6 ± 2.7, 34.4 ± 3.4, and 183.8 ± 54.2 L/d. Approximately 42% of the interviewed producers conducted their activities according to a household production model and the income earned was exclusively from the dairy goat husbandry. Sons and daughters performed an important role in the business (27.80%), but most of them (62.73%) worked out at non farm activities. The percentage of wives that worked directly in the activity (@47%) indicated that it could contribute to gender equity in the rural environment. Most of the production systems (63.16%) presented positive gross margins. We have noticed, however, that shepherds perceived only the business gross margin and that the most accurate registries taken were those related to revenues. In general, producers of the higher strata were favoured by their larger production scale, but asymptotic behaviours for costs and amounts invested in animals, equipments and buildings were observed. These characteristics should be considered when policies related to the dairy goat primary sector have to be planned.Realizou-se um levantamento com base em 19 caprinoculturas de municípios das regiões Centro-Serrana, Norte e Noroeste do estado do Rio de Janeiro e do município de Pedra Dourada, região da Zona da Mata de Minas Gerais, para caracterizar o setor primário da cadeia produtiva do leite de cabra produzido nestas regiões. Foram aplicados questionários com o objetivo de traçar o perfil dos produtores, de suas famílias, do papel da esposa na atividade, da disponibilidade de recursos, da dependência da renda gerada na atividade e do modo como os produtores administravam seu negócio. As fazendas foram distribuídas em cinco estratos de acordo com as médias de produção diária de leite e os desvios-padrão: 8,8 ± 0,9; 15,7 ± 3,9; 22,6 ± 2,7; 34,4 ± 3,4; 183,8 ± 54,2 L/dia. Aproximadamente 42% dos produtores entrevistados conduziam suas atividades segundo o modelo familiar e obtinham renda exclusivamente da caprinocultura leiteira. Os filhos e as filhas desempenhavam papel importante no negócio (27,80%), mas a maior parte (62,73%) trabalhava fora, em atividades não-agrícolas. O percentual de esposas que trabalhavam diretamente na atividade (@47%) indica sua contribuição para a eqüidade entre os gêneros no meio rural. A maioria dos sistemas de produção (63,16%) apresentou margem bruta positiva, todavia, os produtores percebiam apenas a margem bruta do negócio e seus registros mais acurados referiam-se às receitas. Em geral, produtores de estratos mais altos são favorecidos pela produção em escala. Contudo, foram observados comportamentos assintóticos para os custos e montantes investidos em animais, equipamentos e benfeitorias, fato que deve ser considerado no planejamento de políticas relacionadas ao setor primário da caprinocultura leiteira.

Description
An account of the resource
A couve, Brassica oleracea var. acephala, destaca-se entre as plantas hortícolas como sendo frequentemente atacada por pragas, dentre as quais o curuquerê da couve, Ascia monuste orseis (Godart, 1819) (Lepidoptera: Pieridae). O controle desse inseto tem sido feito com inseticidas. Na agricultura orgânica, o uso dos referidos produtos é proibido e já existem alguns casos em que agricultores estão substituindo-o, por outras alternativas menos danosas ao meio ambiente, como as soluções homeopáticas, substâncias apontadas como ferramentas para Agroecologia. Este trabalho teve por objetivo verificar se soluções homeopáticas proporcionam mecanismos de antibiose, como deterrência alimentar, em Ascia monuste orseis, em couve 'manteiga cv. Santo Antônio' e se podem ser utilizadas no controle de pragas. As soluções testadas foram: - Sulphur 12CH; Phosphorus 5CH; Magnesia carbonica 30CH; Ruta 5CH. A testemunha foi água destilada + álcool de cereais 70% 5CH. Para o preparo de cada solução, foram retirados 0,2 ml de cada preparado homeopático, adicionados a 200 ml de água destilada pulverizados nas folhas e nos solo dos vasos. As características analisadas foram peso de lagartas no início e no final do 4° instar; peso seco de pupa (biomassa incorporada), comprimento de lagarta no 4° instar, duração do ciclo ovo-adulto, percentagem de emergência de adultos, comprimento alar, fecundidade das fêmeas e valor nutritivo das couves tratadas. Sulphur 12CH pode ser recomendado como método alternativo eficiente no controle de A. monuste orseis. Todas as soluções homeopáticas, com exceção do Phosphorus 5CH, promoveram deterrência alimentar, mecanismo de antibiose, interferindo no ciclo biológico de A. monuste orseis.

An account of the resource
Há uma preocupação crescente sobre a necessidade de produção e consumo de alimentos mais saudáveis, sem uso de agrotóxicos nem fertilizantes sintético-industriais. Neste contexto se insere a prática da agricultura orgânica, que, contudo, apresenta resultados ainda pouco avaliados nos meios acadêmicos e científicos. Assim, pretendeu-se nesta pesquisa diagnosticar aspectos técnico-ambientais da produção orgânica na região citrícola do Vale do Rio Caí, no Rio Grande do Sul. Inicialmente, foram selecionadas propriedades de oito agricultores familiares, todas já convertidas ao sistema orgânico de produção, sendo aplicadas entrevistas semi-estruturadas. Os produtores mostram-se satisfeitos com o sistema orgânico de produção e revelam bom conhecimento sobre o ambiente, plantas, solos e processos agroecológicos, adquiridos através da participação em eventos técnicos e em reuniões da Cooperativa Ecocitrus. A constante troca de experiências entre esses agricultores tem melhorado sua qualificação técnica, além de melhor conscientizá-los nos aspectos políticos, econômicos e sociais.There's a growing concern about the need for production and consumption of healthier food, without pesticides and chemical fertilizers. The practice of organic agriculture appears in this context, but still shows little assessed results in the academic and scientific context. Thus, this research is aimed at the diagnoses of organic production of citrus in the region of Caí Valley, in southern Brazil. Initially eight producers were selected, all already converted to the organic production system. To carry out the research, semi-structured surveys were applied, seeking the diagnoses of technical and environmental aspects. The organic producers have shown to be satisfied with the organic production system. Moreover, show good knowledge about the environment, plants, soil and agrobiological processes, which is possible technical events and meetings, between these of the Ecocitrus cooperative. The constant sharing of experiences among organic producers has improved their technical qualification, besides providing better awareness in the political, economic and social aspects.

O objetivo do trabalho foi adaptar procedimentos de ensaio existentes para colhedoras autopropelidas e avaliar o desempenho de colhedoras semimontadas, de uma e duas fileiras, operando com três velocidades de deslocamento em dois graus de umidade. Para tanto, foi desenvolvido um dispositivo de coleta do material efluente das máquinas, foram analisadas as perdas de plataforma, de separação e limpeza, de trilha e os parâmetros de qualidade: impureza, danos mecânicos dos grãos e falhas na germinação. O delineamento experimental foi em blocos casualizados, dispostos em esquema fatorial 2 x 3, com seis repetições. Não houve efeito dos tratamentos em relação às perdas na colhedora de uma fileira. Na colhedora de duas fileiras, houve efeito significativo nos fatores, em relação a todas as perdas, exceto as perdas de plataforma, apresentando melhores resultados com o menor grau de umidade (16%) e a maior velocidade de deslocamento (1,52 m s-1). Quanto aos indicadores de qualidade, ambas as colhedoras apresentaram melhores resultados com o menor grau de umidade, na menor velocidade de deslocamento. Concluiu-se que o procedimento adotado foi efetivo para a avaliação do desempenho de colhedoras semimontadas de milho, e o sistema desenvolvido para a coleta de material é eficiente, porém é exigente em mão de obra.The objective of this work was to adapt existent testing procedures for self propelled harvesters and to evaluate semi-mounted commercial harvesters of one and two rows, operating at three forward speeds and two grain moistures. A device was designed and adapted to the machines to collect the material other than grain (MOG) and the indicators analyzed were header loss, separation and cleaning loss, and threshing loss and the quality indicators were: impurity, damage and germination failures. The experiment was conducted as a randomized blocks design disposed in factorial outline 2 x 3, with six replications. There was no effect of treatments related to the losses for the one row harvester. For the two rows harvester there was significant effect in the grain moisture and speed, in relation to all the losses, except to header losses, presenting better results with the lowest grain moisture (16%) and higher forward speed (1.52 m s-1). Related to quality indicators, both harvesters presented better results with the lowest grain moisture in the lowest speed. It was noticed that the procedure for evaluating semi-mounted corn harvesters and the device designed to collect the MOG are efficient but exigent on labor demand.

Description
An account of the resource
Este artigo tem o objetivo de estudar o Programa Nacional de Fortalecimento da Agricultura Familiar (Pronaf) nas suas linhas de crédito para custeio e investimento, com o intuito de investigar suas relações e interfaces com a agricultura familiar, utilizando-se de um estudo no Rio Grande do Sul (microrregião do Médio Alto Uruguai). A pergunta a ser respondia é: qual o tipo de fortalecimento que o Pronaf gera junto aos agricultores familiares? Para isso, se usa como base uma metodologia qualitativa, com a utilização de entrevistas semiestruturadas e se apoia nas argumentações com dados secundários de diversas fontes e pesquisas. Conclui-se que o Programa tem lógica dupla. De um lado, ele está financiando as atividades de produção habituais dos agricultores, como grãos e commodities agrícolas. De outro, há um processo de diversificação econômica das atividades produtivas, das pequenas criações, cultivos e de alimentos básicos ao consumo das famílias.This article aims to study the National Programme for Strengthening Family Agriculture (Pronaf) in their credit lines for costing and investment, in order to investigate their relationships and interfaces with the family farm, using it for a study in Rio Grande do Sul (Middle High Uruguay microregion). The question to be answered is: what kind of building that is generating Pronaf with family farmers? To do this, it was used a methodology based on qualitative, using semi-structured interviews and underpinned by arguments with secondary data from various sources and research. It is concluded that the program has a dual logic. On the one hand, it is financing production activities usual for farmers, such as grain and agricultural commodities. On the other hand, there is a process of economic diversification of productive activities, small livestock, crops and basic food for household consumption.

Description
An account of the resource
Soursop leaves contain bioactive compounds which degrade after being separated from their native matrix. In order to protect their functionality, encapsulation can be applied. This investigation aimed to optimize the parameters for microencapsulating a hydroethanolic extract of soursop leaves after selecting a technique among freeze (FDM) and spray drying (SDM). Selection was performed through a factorial design (23) including as factors: the technique (FDM and SDM), the encapsulant (Gum Arabic and maltodextrin) and its concentration (5% and 10%), for maximizing encapsulation efficiency (EE). Spray drying microencapsulation with maltodextrin at 10% showed the highest EE. Subsequently, the drying temperature and the feeding rate were optimized through a multilevel factorial design to minimize moisture and to maximize the powder solubility and the EE. A significant effect on the response variables (p < 0.05) was found, resulting in 140 ºC and 7 mL/min as optimum parameters. Optimized treatment powder was characterized in terms of microstructure (spherical particles with a random size and irregular surfaces), annonacin content via HPTLC (0.904 ± 0.054 mg/g), color (L* 66.89 ± 0.67, a* 0.06 ± 0.56 and b* 6.01 ± 0.20) and antioxidant capacity (17.88 ± 0.86 and 90.59 ± 1.19 µmol ET/g, by DPPH and ABTS assays). Proposed SDM conditions could be taken into account for preserving bioactive compounds from soursop leaves.

O crescimento do mercado de alimentos livres de agrotóxicos vem gerando interesse de agricultores em sistemas orgânicos de produção. Os adeptos deste sistema promovem mudanças substanciais de seus métodos de produção, adquirindo conhecimentos técnicos e empíricos associados. São necessários, portanto, estudos para avaliar o sistema orgânico neste contexto, comparando-o com o modo de produção convencional, no que diz respeito aos aspectos socioeconômicos e ambientais. Este estudo teve como objetivo o diagnóstico regional desses aspectos em sistemas orgânicos e convencionais do distrito de Sussuanha, município de Guaraciaba do Norte, e do município de São Benedito, no estado do Ceará. Foram entrevistados sete agricultores orgânicos e 21 agricultores convencionais, caracterizando o meio social e as mudanças de qualidade de vida ocorridas com o tempo. As interações agricultor-meio ambiente, no sistema de produção orgânico, geraram melhoria da qualidade de vida das famílias. No sistema convencional, caracterizado pelo uso intensivo de agrotóxicos e grande dependência de adubos químicos, constatou-se que prevalece o interesse em obter a máxima produção sem preocupação com o ambiente. Esta condição se reflete no contato contínuo com agrotóxicos, além das margens de lucros restritivas, o que pode comprometer o uso do solo pelas futuras gerações, pois há uma inerente redução da fertilidade natural dos solos cultivados sob este sistema.

An account of the resource
A Nova Reforma da Política Agrícola Comum (PAC) aprovada em 2003 constitui um reforço dos principais objectivos das reformas anteriores de 1992 e de 2000, como a promoção da competitividade do sector agrícola, da multifuncionalidade dos espaços rurais e agrícolas e da exploração sustentável dos recursos. No essencial, substituem-se as ajudas diretas à produção previstas na maioria dos regulamentos das Organizações Comuns de Mercado, por um regime de pagamento único por exploração sujeito a normas de eco-condicionalidade e a limitações na reconversão dos sistemas de produção agrícola. Este artigo avalia os impactos da nova PAC na competitividade do regadio em Portugal nas explorações agrícolas do Alentejo, nomeadamente, dos efeitos do pagamento único na afetação e na retribuição dos recursos agrícolas, de modo a identificar as principais alterações nas orientações produtivas e nos rendimentos agrícolas. Também são avaliados alguns dos principais impactos sócio-econômicos e ambientais diretos decorrentes dos ajustamentos produzidos com a Nova PAC. A metodologia utilizada baseia-se no desenvolvimento de um modelo micro-econômico de programação matemática estocástica discreta de maximização do valor esperado e de minimização do risco, adaptado às características de uma empresa agrícola do Alentejo. O modelo é utilizado para avaliar prospectivamente o plano de produção e o rendimento no curto e no longo prazo, mediante os cenários da reforma da PAC de 2000 e da Nova Reforma da PAC de 2003.The 2003 Common Agricultural Policy (CAP) reform constitutes a reinforcement of the main objectives of the previous reforms of 1992 and of 2000, namely the promotion of the agricultural competitiveness, the multiple functions of the rural and agricultural areas and the sustainable resource exploitation. The direct production aids in the most Common Market Organizations are replaced by an only payment for each farm, subject to echo-conditionality and limits on the agricultural systems changes. This article evaluates the impacts of 2003 CAP reform on the Portugal irrigation competitiveness in the Alentejo region farms. The effects of the only payment in the agricultural returns, the main changes in the crop patterns and in the agricultural incomes were studied. They are also appraised direct social economic and environmental impacts of the adjustments produced with the 2003 CAP reform. The followed methodology is a discreet stochastic programming model. This model maximizes the expected income and minimizes the risk at the farm level. It was used to assess the crop patterns and the farm income in the short and in the long term, in the scenarios of the 2000 CAP and the of the 2003 CAP.

Um experimento foi desenvolvido no período de outubro de 2009 a fevereiro de 2010, em ambiente telado do Departamento de Solos e Engenharia Rural do Centro de Ciências Agrárias da Universidade Federal da Paraíba, Areia, PB, para avaliar a influência da salinidade da água de irrigação no crescimento inicial do tomate-cereja em solo não salino, sem e com dois tipos de biofertilizante bovino. O delineamento experimental foi inteiramente casualizado em esquema fatorial 5x3, com seis repetições, referente aos valores de condutividade elétrica da água de irrigação: 0,5; 1,0; 2,0; 3,0 e 4,0 dS m-1, em solo sem biofertilizante, com biofertilizante comum e enriquecido com leite, melaço e gesso agrícola. Depois de diluídos em água não salina (0,5 dS m-1) na razão de 1:1. Os biofertilizantes foram aplicados uma única vez, dois dias antes da semeadura, a nível de 10% do volume do substrato. Os biofertilizantes proporcionaram maior crescimento das plantas em relação ao solo sem os respectivos insumos, independentemente do nível de salinidade das águas. A adição do biofertilizante comum e do enriquecido elevou o caráter salino do solo com superioridade sobre os tratamentos com apenas águas salinas, mas sem diferença significativa entre ambos.An experiment was conducted, from October 2009 to February 2010, in a greenhouse of the Soil and Rural Engineering Department from CCA – UFPB, Areia – PB, to evaluate the influence of the irrigation water salinity in the initial growth of the cherry tomatoes in a non-saline soil with and without two types of bovine biofertilizer. The experimental design was completely randomized in factorial scheme 5 x 3, with six repetitions, referring to values of electrical conductivity of the irrigation water: 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1 , in the soil without biofertilizer, with ordinary biofertilizer and enriched with milk, molasses, agricultural gypsum. The biofertilizers after dilution in non-saline water (0.5 dS m-1) in the ratio of 1:1 were applied only once, two days before sowing, equivalent to 10% of the substrate volume. The biofertilizers provided higher growth of plants regarding the soil without the respective inputs, regardless of water salinity level. The addition of ordinary biofertilizer and the enriched compost raised the saline character of soil more than under saline water only, but no significant difference were observed.
