| Food consumers are, in general, concerned with acquiring healthy food which does not pose risks to their health. These preferences are directly related to the way the economic agents organize themselves inside the food sector. In this context, the organic products’ share in the food market is rising considerably, mainly because they consist not only of a healthier product, but also because they contribute positively to the environment. Nevertheless, these characteristics are not immediately observed by the consumers, which makes the certification process an essential mechanism not in the transaction process but also in gaining the confidence of several markets. This article lists some advantages and disadvantages of the certification process raised in the... |

| This paper provides an economic analysis that compares the profitability and land management capability of four different organic cropping systems used to produce winter squash (Cucurbita pepo cv. ‘Delicata’) and cabbage (Brassica oleracea var. capitata cv.’ Farao’). The organic cropping systems are part of a long term experiment designed for vegetable production in the Northeast, and designed to maintain ecological integrity and contribute to environmental stewardship. Our research addresses the causal chain from soil processes to economic outcomes including soil quality, efficiency in cycling of nutrients, off-farm impacts, pressures from weeds, insects and diseases, crop yield and quality, and marketing opportunities. Interactive crop budgets were... |

| Organic farmers face heightened pressure in developing a portfolio of different marketing channels and in bargaining competitively with increasingly sophisticated marketing participants in the supply chain for organic products. This research assists producers by identifying specific farm and demographic factors that enhance earnings given the choice of marketing outlet. The two significant selectivity coefficients confirm that organic earnings when marketing through a single outlet are biased upward since farmers who are better suited to market through multiple outlets have already moved away from this marketing strategy. An accurate evaluation of the projected earnings from any marketing strategy must account for selectivity effects. |

| Dado que o desenvolvimento de sistemas de produção orgânica, em relação aos convencionais, implica em mudanças importantes na estrutura e na tecnologia empregadas, buscou-se mensurar e analisar, em condições determinísticas e de riscos, os níveis de eficiência econômica e de viabilidade financeira da produção orgânica de 'Niágara Rosada', sem e com o uso de cobertura plástica, desenvolvida pela Embrapa Uva e Vinho. |

| The aim of this work was to evaluate biological indicators of soils used under the systems of organic farming, agroforestry and pasture in the south western part of the Amazon region of Brazil. The experiment was carried out at the Seridó Ecological Site, located in Rio Branco, in the state of Acre, Brazil. The experimental design was completely randomised, with five treatments (land-use systems) and six replications, with each replication consisting of four single samples. The systems of land use evaluated were: 1) native forest (control); 2) agroforestry (AFS); 3) pasture; 4) intercropped passion fruit, maize, cassava, pineapple and forage peanut; and 5) intercropped passion fruit, maize, cassava, pineapple and tropical kudzu. It was found that organic... |

| O objetivo desse trabalho foi avaliar o efeito da cobertura do solo com aveia preta e manutenção da palha sobre o terreno, bem como cobertura do solo com filme de polietileno preto, sobre a produção de biomassa e teores de Mn e Zn, em alface cultivada no sistema orgânico, por dois anos consecutivos. Utilizaram-se cinco tratamentos: solo sem cobertura, coberto com filme de polietileno preto, coberto com aveia deitada, coberto com aveia ceifada e solo coberto com aveia na sua forma natural, para o cultivo de três cultivares de alface. O experimento seguiu delineamento experimental de blocos ao acaso, com quatro repetições e análise estatística com parcelas subdivididas. Concluiu-se que o cultivo de alface em sucessão à aveia preta, sobre a palha, promoveu... |

| ABSTRACT This study was conducted to compare edible giblets weight, tibial bone mineral density (BMD), and bone mineral content (BMC) of two slow-growing broiler genotypes (Hubbard S757; S757 and Hubbard Grey Barred JA; GB-JA) reared with outdoor access, and to determine the relationship between these variables. Day-old chicks (straight-run) of the genotypes S757 (n=120) and GB-JA (n=120) were housed for 98 days. Each genotype was assigned to six pens of 20 birds each. Birds were reared in indoor floor pens and moving shelters with outdoor access (during daylight hours). Absolute body (BW), heart (HW), spleen (SW), liver (LW), gizzard (GW), and abdominal fat pad (AFW) weights of the genotype S757 and male birds were statistically higher than that of the... |

| In many agricultural experiments the variables are biologically correlated and it is inappropriate to study them only under univariate analysis. Therefore, we evaluated commercial characteristics of crisphead lettuce cultivars and covers under a multivariate approach, using canonical discriminant analysis. We used a split plot design and we tested the cover crop, cultivar and interaction effects by using MANOVA (α= 5%). Means and its standard errors were obtained for average total weight, weight of the head, volume and density of plants. Canonical discriminant analyses were performed using PROC CANDISC procedure in SAS (SAS Institute, 2008) system. Canonical plots were obtained using JMP 9.0 (SAS Institute, 2010) linked to SAS database. With these plots it... |

| ABSTRACT Pesticide environmental risks and increased weed resistance have encouraged studies for alternatives to herbicides. Among these are weed thermal control methods by controlled heat application machines. Thus, this study aimed to test a prototype of heat-applicator machine as a function of changes in gas pressure, travel speed, and tire traffic effect on plants. Then, three experimental factors were tested: gas pressure (98, 196, and 245 kPa), travel speed (0.56, 0.78, and 1.17 m s−1), and tire traffic effect on plants (with and without traffic). The results showed that tire traffic effect on plants and subsequent heat application had no effect on control rate. Weed control rates reached levels considered satisfactory using a heat application speed... |
