Title A name given to the resource O perfil socioeconômico e o uso de Tecnologias de Informação e Comunicação (TIC) pela agricultura familiar no Vale do Caí/RS Creator An entity primarily responsible for making the resource Luana Barcelos, Douglas Ritt, Cidonea Machado Deponti, Silvio Cezar Arend Description An account of the resource O presente artigo refere-se ao projeto de pesquisa e de extensão denominado 'O uso e a apropriação de TICs pela agricultura familiar no Vale do Caí - RS', financiado pelo edital do MCTI/CNPq. O objetivo deste artigo é traçar o perfil socioeconômico dos agricultores familiares do Vale Caí e verificar o uso das TIC (Tecnologias de Informação e Comunicação) pelos agricultores familiares. Foram aplicados 375 formulários de entrevistas semiestruturados com informações socioeconômicas e culturais que serviram de base para a formação do perfil dos agricultores estudados e questões relativas ao uso e à apropriação das TIC. Essas informações foram tabuladas e verificou-se que os agricultores familiares do Vale do Caí, de acordo com resultados levantados, apresentam idade média de aproximadamente 42 anos, moram com a família na propriedade rural, cultivam principalmente a silvicultura e a citricultura, pouco mais da metade tem rendimentos de até 2 salários mínimos ao mês e apresentam baixa escolaridade, basicamente o ensino fundamental incompleto. No que tange ao uso das TIC destaca-se que somente 16 propriedades não possuem bens de comunicação e de informática e em relação ao acesso à internet, constata-se que 46,1% dos entrevistados acessam diariamente a rede.

Title A name given to the resource Nitrogen fixation by groundnut and velvet bean and residual benefit to a subsequent maize crop Fixação de nitrogênio por amendoim e mucuna e benefício residual para uma cultura de milho Creator An entity primarily responsible for making the resource Bruno José Rodrigues Alves, Segundo Urquiaga, Ambate Okito, Robert Michael Boddey Description An account of the resource Chemical fertilisers are rarely avaiable to poor farmers, for whom the nitrogen (N) is often the most limiting element for cereal grain production. The objective of this study was to quantify the contribution of biological nitrogen fixation (BNF) to groundnut (Arachis hypogaea) and velvet bean (Mucuna pruriens) crops using the 15N natural abundance (delta15N) technique and to determine their residual effect and that of a natural fallow, on growth and N accumulation by two rustic maize varieties. The contribution of BNF calculated from delta15N data was 40.9, 59.6 and 30.9 kg ha-1, for groundnut, velvet bean and the natural fallow, respectively. The only legume grain harvested was from the groundnut, which yielded approximately 1.000 kg ha-1. The subsequent maize varieties ('Sol de Manhã' and 'Caiana Sobralha') yielded between 1.958 and 2.971 kg ha-1, and were higher after velvet bean for both maize varieties and 'Sol da Manhã' groundnut, followed by 'Caiana' after groundnut and, finally, the natural fallow. For a small-holder producer the most attractive system is the groundnut followed by maize, as, in this treatment, both groundnut and maize grain harvest are possible. However, a simple N balance calculation indicated that the groundnut-maize sequence would, in the long term, deplete soil N reserves, while the velvet bean-maize sequence would lead to a build up of soil nitrogen.Fertilizantes químicos raramente estão disponíveis aos agricultores com poucos recursos econômicos, e assim o N é, freqüentemente, um elemento mais limitante para a produção de grãos. O objetivo deste trabalho foi quantificar a contribuição da fixação biológica de nitrogênio (FBN) às culturas de amendoim (Arachis hypogaea) e mucuna (Mucuna pruriens), por meio da técnica de abundância natural de 15N e determinar o efeito residual das leguminosas e do pousio sobre o crescimento e acumulação de N em duas variedades de milho. A contribuição da FBN calculada a partir dos dados de delta15N, foi de 40,9, 59,6 e 30,9 kg ha-1, respectivamente, para amendoim, mucuna e o pousio. A única leguminosa de grão colhida foi amendoim que produziu aproximadamente 1,000 kg ha-1. A produtividade da cultura de milho (variedades Caiana e Sol da Manhã) variou de 1,958 a 2,971 kg ha-1 de grãos, sendo mais alta após mucuna em ambas as variedades de milho e após amendoim na Sol da Manhã, seguida por Caiana após amendoim e por último o pousio normal. Para pequenos agricultores o sistema mais atrativo é o que inclui amendoim seguido pelo milho, uma vez que duas colheitas de grãos são possíveis. Contudo, o cálculo do balanço de N indicou que a seqüência amendoim-milho diminuiria, a longo-prazo, a reserva de N do solo, enquanto a seqüência mucuna-milho ajudaria a aumentar a reserva de N do solo.

The treatments were a mixture of twochemical pesticides (Chlorothalonil and Pyraclostrobin) and a biological one (Bacillus subtilis) with andwithout fertilizers. In total there were 16 treatments with 3 repetitions, installed in a CCN-51commercial cocoa farms and under a Randomized Complete Block Design (RCBD). The results showedthat the use of fungicides (chemical and biological), decreased the incidence of 'moniliasis'(Moniliophthora roreri), 'brown spot' (Phytophthora spp.) and 'cherelle wilt'; but the application offertilizers did not increase the effectiveness of these products. The treatment only agricultural laborsdid not decrease the final incidence of 'moniliasis', nor of the 'brown rot'; instead, the final incidenceof 'cherelle wilt' increased. The number of cocoa fruits and yield were not directly related and thehighest yield of dry cocoa beans corresponded to T2 [Agricultural labors + Clorotalonil (1 kg ha-1) (c/15days) + Pyraclostrobin (0.5 kg.ha-1) (c/90 days) + Fertilizers (0.4 kg.ha-1) + organic fertilizer (2kg/planta)], which also had the highest net income/ha.

Title A name given to the resource Establishment of the size of portions of fruit and vegetable consumption for use in food guides in the Spanish environment: proposal of the Scientific Committee of the '5 a day' Association Creator An entity primarily responsible for making the resource Giuseppe Russolillo, Eduard Baladia, Manuel Moñino, Iva Marques-Lopes, Andreu Farran, Joan Bonany, Victoria Gilabert, Iciar Astiasarán, Maria Dolores Raigón, Alfredo Martínez, Juan Manuel Ballesteros, Francesc Miret, Andreu Palou, María Dolores Romero-de-Ávila, Isabel Polanco, Esperanza Torija, Fernando Rodríguez-Artalejo, Nuria Martínez Description An account of the resource Introduction: food servings are standard amounts of food stuffs or drinks to help dietetic advice to promote and preserve health. The aim is to establish the serving size of fruits and vegetables (FH) to be used in food based dietary guidelines (FBDG). Material and methods: Methodology of the United States Department of Agriculture (USDA) was adapted to establish serving sizes for FBDG, along of the followed by the food exchange system. Data was collected from the FH portion sizes reported in nutritional surveys and common sizes available in the Spanish market, and they were adjusted to an easily recognisable quantities of food with equivalence on key nutrients: the compliance with public health goals for FH consumption was evaluated. Results: Portion sizes typically reported in Spanish nutrition surveys are scarce and not homogeneous, and no data published in scientific journals on portion sizes were available. The Spanish FBDG, in spite of showing a range of serving size for FH, do not assure that they are interchangeable nor specify the method to obtein them.The serving of vegetables was 139,44 g (DS:± 21.98, CV: 0.16), 137,68 g (DS:± 49,61, CV: 0,36) for fruits and 28.00 g (DS:± 7,53, CV: 0.,27) for dried fruits. Conclusions: With the established servings, the recommendation of consuming at least 5 servings of FH a day' would allow reaching the Public Health goals for FH established in 600 g (net weight) / person / day. It is recommended that the Spanish Agency for Consumers, Food Safety and Nutrition (AECOSAN) uses this methodology to establish serving sizes for the rest of food groups that make up the FBDG for the Spanish population.

A caracterização fitotécnica compreendeu a massa do fruto, o diâmetro transversal e longitudinal e a espessura da 'casca' e a contagem de sementes viáveis e inviáveis por fruto. Realizou-se um experimento para cada porta-enxerto, em casa de vegetação sob nebulização intermitente, e as avaliações foram a cada 3 dias, após o início do processo germinativo, verificando-se porcentagem de germinação e índice de velocidade de germinação. A utilização do GA3 e a retirada do tegumento em sementes do porta-enxerto Flying Dragon aumentam a porcentagem de germinação e o índice de velocidade de germinação, e para o porta-enxerto citrumelo Swingle, a retirada do tegumento das sementes aumenta a porcentagem de germinação e o índice de velocidade de germinação.The objective was phytotechnical characterization of fruits, assess the effect of removing the husk of the seed, the influence of GA3 and growth promoter (Stimulate®) on the germination of seeds of rootstock Flying Dragon and citrumelo Swingle. The phytotechnical characterization included the weight of the fruit, transverse and longitudinal diameter and thickness of the 'peel' and the counting of viable and unviable seeds per fruit. There was an experiment for each rootstock in green house under intermitent mist and the evaluations were every 3 days after the beginning of the germination process, there is percentage of germination and germination speed. The use of GA3 and removal of seed husk of the rootstock Flying Dragon increase the germination percentage and germination speed, and the rootstock citrumelo Swingle removal of the husk of seeds increase the germination percentage and the germination speed.

Esta importância tem motivado a busca por formas de consolidação desta atividade, principalmente a agricultura familiar. Com o objetivo de avaliar as características dos solos, relacionando-os as percepções e avaliações dos agricultores locais, dois assentamentos da RMPA foram visitados, e lotes de moradia e produção familiar escolhidos para este trabalho. Foram utilizados recursos de entrevista semiestruturada, caminhamento e escolha de algumas glebas para amostragem e observação dos solos. Os resultados mostraram que estes solos têm limitações ao uso, como textura arenosa, baixa fertilidade natural e drenagem restrita em algumas áreas. Os assentados conseguem distinguir estas características, e para isto foi importante a comparação com os solos de suas localidades de origem. Este público demonstrou maior familiaridade com abordagens no campo, evidenciando serem estas as formas mais produtivas de diálogo com técnicos e pesquisadores. Foi percebida a identidade entre várias observações do público, e critérios e atributos técnico-científicos utilizados em levantamentos e avalição de aptidão de uso das terras, mostrando a aproximação entre estas diferentes formas de saber, e viabilizando trabalhos no sentido de planejamento de sistemas de produção sustentáveis, de forma participativa.

Title A name given to the resource ATRIBUTOS QUÍMICOS DO SOLO UTILIZANDO COMPOSTO ORGÂNICO EM CONSÓRCIO DE ALFACE-CENOURA SOIL CHEMICAL ATTRIBUTES USING ORGANIC COMPOST IN LETTUCE-CARROT INTERCROPPING Creator An entity primarily responsible for making the resource Angela Maria Quintão Lana, Márcio Sampaio Pimentel, Helvécio De-Polli De-Polli Description An account of the resource  A utilização indiscriminada de fertilizantes responde por problemas relacionados à lixiviação e escoamento superficial, tornando mais negativo o balanço energético na olericultura. Por este prisma, a agricultura orgânica busca otimizar a utilização de recursos naturais na propriedade e evitar desperdícios pela adoção de práticas conservacionistas. Dessa forma, dois experimentos de consórcios de alface-cenoura, submetidos a 0 t ha-1, 12 t ha-1, 24 t ha-1 e 48 t ha-1 de composto orgânico, foram realizados em 2000, no município de Seropédica, RJ, com o objetivo de monitorar os teores de P, K, Ca, Mg e pH, em Argissolo Vermelho-Amarelo. O delineamento experimental foi em blocos ao acaso, com cinco repetições. Os tratamentos foram combinados em esquema de parcela subdividida no tempo, sendo as doses de composto orgânico as parcelas, e as coletas de solo as subparcelas. As coletas de solo foram realizadas na profundidade de 0-10 cm, 15 dias antes da instalação (DAI), 0, 6, 57 e 101 dias após plantio (DAP), no primeiro experimento, e 8 DAI, 1, 6, 60 e 116 DAP, para o segundo experimento. Quando submetido a doses crescentes de composto orgânico, independentemente do composto, P e K responderam às doses, enquanto Ca e Mg foram influenciados pela qualidade do composto. O período de máxima disponibilidade de P, K, Ca e Mg às plantas foi aos 6 DAP, em ambos os experimentos. As maiores correlações foram obtidas em P x Ca, P x Mg e K x Ca e apresentaram variação com a qualidade do composto orgânico. PALAVRAS-CHAVE: Dinâmica de nutrientes; fósforo; potássio; adubação orgânica. Indiscriminate use of fertilizers is responsible for problems as leaching and surface runoff, making more negative the energy balance in agroecosystems. The organic soil management using biological practices avoids waste and optimizes the exploration of natural resources. Two experiments, with intercropped lettuce and carrot and fertilized with organic compost (0 t ha-1, 12 t ha-1, 24 t ha-1, and 48 t ha-1), were conducted in Seropédica, Rio de Janeiro State, Brazil, during the year 2000, to observe P, K, Ca, and Mg levels, and pH in an Ultisol. Twenty treatments were evaluated using a complete randomized block design, with four replications. The treatments were combined as plots split in time, using doses of organic compost as main plots, and five collecting times as split plots. Soil was sampled at 0-10 cm, before and during the experimental period: 15 days before installation (DBI), 0, 6, 57, and 101 days after planting (DAP), in the first experiment, and 8 DBI, 1, 6, 60, and 116 DAP, in the second. P and K reflected the compost doses, independently of compost type, while Ca and Mg were dependent on compost quality. The period of maximum availability of P, K, Ca, and Mg occurred at 6 DAP, for both experiments. Highest correlations occurred between P and Ca, P and Mg, and K and Ca, which were associated with organic compost quality. KEY-WORDS: Nutrients dynamics; phosphorus; potassium; organic manure.
