| 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... |

| 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... |

| 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. |

| The paper deals with organic produce in one of the largest and, concerning organic production one of the most diffused counties in Hungary, Pest County located in the north-central part of the country. Factors influencing farmers’ decision on adopting or not e.g. farm size, farm type, location, structure, market for organic products, existence of organic AEM were analysed. Hypotheses based on previous empirical literature were tested by a model explicitly accounting for the effects of farm-specific variables like age, education, size of farms and share of rented land. Logit model was estimated on a cross-section data set of Hungarian farmers for the period 2007. It appears that education has a positive impact on the choice between conventional and organic... |

| 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... |

| ABSTRACT The therapeutic efficacy of herbal medicines and pesticides has increased the need to define cultivation parameters for medicinal plants. The objective of this study was to evaluate the production of essential oil and flavonoids of chamomile under irrigation levels and organic fertilizer doses. The experiment was conducted in the experimental area of the Campus II of the University of Western São Paulo, in the city of Presidente Prudente, SP, Brazil. The experimental design was a randomized block in triple factorial (6 x 2 x 3), corresponding to irrigation depths (150, 100, 75, 50, 25 and 0% of the reference evapotranspiration (ETo)), organic fertilizers (poultry manure and cattle manure) and the fertilizer doses (0, 3 and 5 kg m-2), with four... |

| ABSTRACT With the occurrence of prolonged droughts in the Brazilian semi-arid region, water scarcity directly influences agriculture in this region, so that water reuse and bovine manure application become a viable alternative for pepper production. In this context, the present study aimed to evaluate the sustainable production of chili peppers (Capsicum frutescens) under levels of irrigation with treated wastewater and doses of bovine manure. The following bovine manure doses were considered: D1 (0% manure and 100% soil), D2 (10% manure and 90% soil), D3 (20% manure and 80% soil), D4 (30% manure and 70% soil), D5 (40% manure and 60% soil) and D6 (50% manure and 50% soil), based on volume. Three levels of irrigation were applied, based on the water... |

| 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: The aim of the present study was to evaluate the effect of different irrigation depths on the yield, water use efficiency (WUE), and yield response factor (Ky) of carrot (cv. 'Brasília') in the edaphoclimatic conditions of Baixada Fluminense, RJ, Brazil. Field trials were conducted in a Red-Yellow Argisol in the 2010-2011period. A randomized block design was used, with 5 treatments (depths) and 4 replicates. Depths were applied by drippers with different flow rates, and the irrigation was managed by time domain reflectometry (TDR) technique. The reference (ETo) and crop (ETc) evapotranspiration depths reached 286.3 and 264.1mm in 2010, and 336.0 and 329.9mm in 2011, respectively. The root yield varied from 30.4 to 68.9t ha-1 as a response to... |
