Title A name given to the resource Efeitos do Pronaf sobre a produção agrícola familiar dos municípios tocantinenses Creator An entity primarily responsible for making the resource Eder Lucinda Pereira, Jean Santos Nascimento Description An account of the resource Este artigo tem por objetivo avaliar a capacidade do Pronaf de contribuir para a redução do hiato entre o potencial produtivo e o produto efetivo da agropecuária tocantinense. Em termos metodológicos, além das análises descritivas, foram empregadas a regressão linear pela média e a regressão quantílica. A pesquisa concentrou-se no estado do Tocantins, abarcando todos os municípios (unidades de análise), no período de 2002 a 2009. Foram evidenciadas a importância relativa do setor agrícola para a economia tocantinense, a forte participação da agricultura familiar na produção total do setor e a significativa presença do Pronaf, que, para além de contribuir no processo de legitimação da agricultura familiar, como ressaltado em estudos anteriores, se mostrou capaz de estimular a produção vegetal e animal dos municípios estudados. Além disso, dadas as especificidades do Pronaf no Tocantins, em termos de cobertura e distribuição dos recursos, supõe-se que as constatações confiram ao programa características para também contribuir no processo de redução da desigualdade no estado. Entretanto, adverte-se que, embora o programa mereça a atenção dos formuladores de políticas, dada sua capacidade de estimular a produção agrícola municipal, deve-se concebê-lo como uma intervenção de caráter complementar, já que o trabalho familiar, como registrado na literatura, se mostrou decisivo no desempenho produtivo da agricultura familiar.

Title A name given to the resource Cultivation of Agaricus blazei on Pleurotus spp. spent substrate Creator An entity primarily responsible for making the resource Regina Maria Miranda Gern, Nelson Libardi Junior, Gabriela Nunes Patrício, Elisabeth Wisbeck, Mariane Bonatti Chaves, Sandra Aparecida Furlan Description An account of the resource The aim of this work was the use of Pleurotus ostreatus and Pleurotus sajor-caju for the previous lignocellulolytic decomposition of banana tree leaf straw and the further use of the degraded straw as substrate for the culture of Agaricus blazei. For optimising the production of A. blazei in terms of yield (Y%) and biological efficiency (BE%), adjustments to the composition of the substrate were evaluated in a 2(5) experimental design. The following components were tested in relation to % of substrate dry mass: urea (1 and 10%), rice bran (10 or 20%) or ammonium sulphate (0 or 10%), inoculum (10 or 20%) and the casing material (subsoil or burned rice husks). The best results (79.71 Y% and 6.73 BE%) were found when the substrate containing 10% of rice bran, without ammonium sulphate, inoculated with 20% and covered with subsoil was used.O cultivo de fungos comestíveis e medicinais utilizando resíduos da agroindústria vem se apresentando como uma alternativa econômica para o pequeno produtor rural, favorecendo a agricultura familiar do nordeste catarinense. Este trabalho avaliou o fungo Pleurotus para a decomposição lignocelulolítica de palha de folhas de bananeira e a utilização da palha residual como substrato para o cultivo de Agaricus blazei. Ajustes na composição do substrato residual de Pleurotus, tais como o tipo e a concentração da fonte de nitrogênio, a porcentagem de inóculo e a camada de cobertura, foram avaliadas. O substrato residual que mais favoreceu a produção de A. blazei em Eficiência Biológica (6,73%), Rendimento (79,71%) e menor tempo para emissão do primeiro primórdio (27 dias) foi o substrato residual de P. ostreatus inoculado com 20% de inóculo (ms), 10% de farelo de arroz (ms), sem sulfato de amônio e utilizando terra de subsolo como camada de cobertura.

Title A name given to the resource Índices emergéticos de sustentabilidade da produção leiteira em uma propriedade de base familiar em Palmeira, Paraná, Brasil Creator An entity primarily responsible for making the resource Pedro Henrique Weirich Neto, Joelcio Eurich, Carlos Hugo Rocha Description An account of the resource Na busca da sustentabilidade, metodologias para obtenção de parâmetros ou índices representativos seriam ferramentas básicas e essenciais para acompanhamento das gestões dos processos. Este trabalho teve por objetivo o cálculo de índices emergéticos para avaliação da sustentabilidade da produção leiteira. Para isso, o estudo foi realizado em uma propriedade rural, de base familiar, localizada no município de Palmeira, Paraná. A partir dos dados reais da propriedade, calculou-se a razão de rendimento emergético líquido (EYR), a razão de investimento de emergia (EIR), a carga ambiental (ELR), a razão de intercâmbio de emergia (EER), a renovabilidade (%R), a rentabilidade econômica simples (RES) e o índice de sustentabilidade (SI). Fundamentado nos métodos de análise emergética, foram encontrados os seguintes valores: EYR = 1,33; EIR = 3,05; ELR = 3,15; EER = 1,71; %R = 24; SI = 0,42; RES = 0,12. Estes índices demonstram que apesar de economicamente viável, RES = 0,12, em termos energéticos a propriedade apresenta-se com um baixo índice de sustentabilidade (SI).

Title A name given to the resource Effect of planting density on green ear yield of maize cultivars bred in different periods Efeito da densidade de plantio sobre o rendimento de espigas verdes de cultivares de milho desenvolvidas em diferentes épocas Creator An entity primarily responsible for making the resource Paulo Sérgio L e Silva, Severino R Duarte, Fábio Henrique T de Oliveira, Júlio César do V Silva Description An account of the resource Corn cultivation in the Northeast region of Brazil is characterized by a great diversity of production systems, ranging from large companies (modern cultivars and relatively high planting densities) to small farms (family agriculture, traditional cultivars, and low planting densities). In the present work we evaluated the effects of planting density (30; 40; 50; 60; or 70 thousand plants ha-1 - TPH) on green ear yield of cultivars Centralmex (traditional) and AG 510 (hybrid). Different densities were achieved by maintaining 1.0 m between rows and varying the spacing between pits, within the row. Cultivars and planting densities were combined in a factorial scheme, arranged in a random block design with four replicates and four 6 m long row plots. The number of green ears increased with density in both cultivars, but in a significantly more intense pace in cultivar AG 510. Cultivar AG-510 (14.9 t ha-1 on average, maximum yield at 58 TPH) yielded significantly more unhusked green ears than cultivar Centralmex (13.6 t ha-1 on average, maximum at 61 TPH). Marketable green ear yield increased with density in both cultivars, but more intensively in cultivar AG 510, which significantly out yielded cultivar Centralmex from 43 TPH ahead. The difference between cultivars at the planting density of 70 TPH was 14.4 t ha-1. There was no response of cultivar Centralmex in number of marketable husked green ears, while cultivar AG 510 increased yield with planting density. The difference between both cultivars started being significant at 38 TPH. Husked ear length decreased linearly and similarly in both cultivars as planting density increased. Planting density did not influence plant and ear height, and cultivar Centralmex was superior in both characteristics at all planting densities. There was no effect of cultivars on stalk diameter and root system biomass. Both characteristics decreased linearly as planting density increased.O cultivo do milho na região Nordeste do Brasil é caracterizado por uma grande diversidade de sistemas de produção, que variam de grandes empresas (cultivares modernas e densidades de plantio relativamente elevadas) a pequenas propriedades (agricultura familiar, cultivares tradicionais e baixas densidades de plantio). O objetivo do presente trabalho foi avaliar os efeitos da densidade de plantio (30; 40; 50; ou 70 mil plantas ha-1 - MPH) sobre o rendimento de espigas verdes das cultivares Centralmex (tradicional) e AG 510 (híbrido). As diferentes densidades foram obtidas mantendo-se 1,0 m entre fileiras e variando-se o espaçamento entre covas na fileira. As cultivares e densidades de plantio foram combinadas em um arranjo fatorial disposto no delineamento de blocos ao acaso, com quatro repetições e parcelas com quatro fileiras de 6,0 m. O número de espigas verdes aumentou com a densidade nas duas cultivares, mas de maneira significativamente mais intensa na cultivar AG 510. A cultivar AG 510 (com rendimento médio de 14,9 t ha-1 e rendimento máximo na densidade de 58 MPH) produziu significativamente mais espigas verdes despalhadas que a cultivar Centralmex (rendimento médio de 13,6 t ha-1 e rendimento máximo na densidade de 61 MPH). O rendimento de espigas verdes comercializáveis aumentou com a densidade de plantio nas duas cultivares, mas mais intensamente na cultivar AG 510, que superou significativamente a cultivar Centralmex a partir da densidade de 43 MPH. A diferença entre cultivares na densidade de plantio de 70 MPH foi 14,4 t ha-1. Não houve alteração significativa no número de espigas despalhadas comercializáveis na cultivar Centralmex. Porém, na cultivar AG 510, essa característica aumentou com a densidade de plantio. A diferença entre as cultivares tornou-se significativa a partir de 38 MPH. O comprimento da espiga despalhada diminuiu linearmente e de maneira similar em ambas as cultivares com o aumento da densidade de plantio. A densidade de plantio não influenciou as alturas da planta e de inserção da espiga, com superioridade da cultivar Centralmex para essas características em todas as densidades de plantio. Não existiu efeito de cultivares sobre o diâmetro do colmo e biomassa do sistema radicular e ambas características diminuíram linearmente com o aumento da densidade de plantio.

Title A name given to the resource Viabilidade agronômica de consórcios entre cebola e alface no sistema orgânico de produção Agronomic viability of onion and lettuce intercropped in the organic cultivation system Creator An entity primarily responsible for making the resource José Carlos Polidoro, José Guilherme M Guerra, Raul de LD Ribeiro, Patrícia D de Paula, Marcius Nei Z Cesar, Rejane E Guedes Description An account of the resource Foram comparados três consórcios de cebola (cv. Alfa Tropical) e alface (cv. Regina 2000), variando o intervalo de tempo entre transplantios de cada espécie para o campo. O experimento, no delineamento de blocos casualizados, constou dos tratamentos monocultivos de cebola e de alface e três consórcios entre as olerícolas, em seis repetições, mantendo-se o espaçamento da cebola e transplantando- se a alface no mesmo dia, 15 dias e 30 dias depois da cebola. A alface ocupou as entrelinhas alternadas da cebola, representando, em todos os consórcios, metade da densidade populacional do respectivo monocultivo. Com exceção do último tratamento (alface 30 dias após a cebola), os consórcios mostraram-se vantajosos em termos de elevação de renda por unidade de área cultivada. A introdução da alface não reduziu a produtividade da cebola, em bulbos de padrão comercial e o crescimento da folhosa foi comparável ao do seu monocultivo. Os índices de equivalência de área confirmaram a viabilidade do cultivo consorciado, o qual, a par do adequado desempenho agronômico, possibilita um melhor aproveitamento de insumos e serviços no manejo orgânico adotado.Three intercrops of onion (cv. Alfa Tropical) and lettuce (cv. Regina 2000) were compared, varying the time intervals between transplants of each one in the field. The experiment was made in a complete randomized block design with the treatments (replicated six times): monocrops of onion and of lettuce, and intercrops of the two vegetables keeping the same onion spacing arrangement, with lettuce transplanted on the same day, 15 days, and 30 days after onion. Lettuce seedlings were placed between onion rows in an alternating manner, thus corresponding to half of its monocrop population density. Except for the last treatment (lettuce 30 days after onion planting) the intercropping system was advantageous in terms of increased income by cultivated area unit. Introducing lettuce into the system did not decrease onion yield in marketable bulbs. In addition, lettuce growth was comparable to that of its monocrop. The land equivalent ratio values confirmed the viability of intercropping onion and lettuce. Besides the adequate agronomic performance, the system leads to more efficiency of inputs and hand labor utilization under the organic management adopted.

Title A name given to the resource Agroecologia, consumo sustentável e aprendizado coletivo no Brasil Agroecology, sustainable consumption and collective learning in Brazil Creator An entity primarily responsible for making the resource Fernando Passos dos Santos, Leila Chalub-Martins Description An account of the resource O que acontece quando consumidores e produtores agroecológicos adotam uma prática econômica alternativa ao consumo convencional? O presente artigo analisa e qualifica as comunidades aprendentes existentes no âmbito desse tipo de prática econômica. O estudo de caso do grupo de consumo coletivo de produtos agroecológicos Trocas Verdes, situado em Campinas (SP), no contexto da agricultura familiar no Brasil, mostrou que as trocas econômicas são também trocas de saberes. Além disso, tais trocas constituem uma práxis em educação ambiental. As três dimensões da sustentabilidade - econômica, social e ambiental - são as categorias de análise utilizadas para determinar o potencial pedagógico existente na articulação de uma prática de consumo coletivo. A partir da metodologia da pesquisa participante, observou-se que, na venda direta de produtos agroecológicos a grupos de consumidores organizados de forma autônoma ou que funcionam em regime de autogestão, essa prática econômica também caracteriza um processo de educação ambiental crítica, pois possibilita que se apreenda coletivamente a realidade socioeconômica dos atores envolvidos. As dinâmicas socioeconômicas são objeto de aprendizado dos consumidores e pesquisadores atuantes nas compras e, assim, conclui-se que esse tipo de prática promove um aprendizado coletivo. O presente estudo confirma que um importante fator para a existência de comunidades aprendentes é a autogestão da organização social.What happens when consumers and agro-ecological producers adopt an economic practice alternative to conventional consumption? This article characterizes and analyzes the learning communities which exist within this type of economic practice. The case study of Trocas Verdes (Green Exchange), - a group of collective consumption of agro-ecological products, located in Campinas (SP) - in the context of family farming in Brazil, has shown that economic exchanges are also exchanges of knowledge. Moreover, these exchanges constitute a praxis in environmental education. To determine the educational potential which exists in the articulation of a practice of collective consumption, we have used the three dimensions of sustainability - economic, social and environmental - as categories of analysis. Based on the participatory research methodology, we have observed that in the direct sale of agro-ecological products to groups of consumers that are organized independently or self-managed, this economic practice also characterizes a process of critical environmental education, because it allows learning collectively the socioeconomic reality of the actors involved. The socio-economic dynamics are learnt by the consumers and researchers working in the trade, and thus it is possible to conclude that this practice promotes collective learning. This study confirms that an important factor for the existence of learning communities is the self-management of social organizations.
