| A regiao do Nordeste Mineiro e a quarta maior regiao produtora de cafe do Cerrado. Seu cafe tem sido considerado de ma qualidade devido ao despreparo ou falta de tecnica de alguns pequenos e medios produtores no processo de pos-colheita. Levando-se em conta o baixo preco da terra, a facilidade de contratar mao-de-obra e as condicoes edafoclimaticas, essa regiao podera tornar-se uma das maiores produtoras de cafe do Pais. Compreende tres Polos de influencia: Teofilo Otoni, abrangendo dezoito municipios e um milhao de hectares, caracteriza-se por ter grandes cafeicultores. O cafe e a principal cultura e, talvez, unica atividade agricola em escala comercial; Capelinha com dezesseis municipios numa area de 1,6 milhoes de hectares. Nesse polo predominam medios... |

| An indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) for ochratoxin A (OTA) detection in green, roasted and instant coffees was developed using anti-OTA monoclonal antibody. Immunological reagents prepared were OTA-BSA (4.76 mg/mL), anti-OTA.7 MAb (2x10³-fold dilution) and HRP-anti IgG (10³-fold dilution). The detection limit was 3.73 ng OTA/g and correlation coefficients (r) between this immunoassay and high performance liquid chromatography were 0.98 for green coffee, 0.98 for roasted and 0.86 for instant. OTA levels detected by ic-ELISA were higher than by HPLC, with ELISA/HPLC ratio of 0.66 - 1.46 (green coffee), 0.96 - 1.11 (roasted) and 0.93 - 1.82 (instant). ELISA recoveries for OTA added to coffee (5 - 70 ng/g) were 81.53 % for... |

| The objective of this study was to determine the damage levels caused by Orthezia praelonga Douglas, 1891 and Leucoptera coffeella (Guérin-Mèneville 1842), on rangpur lime and Obatã coffee leaves, respectively. Measurements were based on a new concept for the evaluation of the following plant physiological parameters: photosynthesis, stomatal conductance, leaf temperature and transpiration, and internal concentration of CO2 (by infrared analyzer). A negative correlation between infestation level and photosynthesis was found, where the negative inflexion point of the curve was considered as a reference for damage levels. The control level for O. praelonga is below the 7-13% limit for damaged leaf area (40 to 70 scales per leaf), while for L. coffeella it is... |

| ABSTRACT: The development of Coffea canephora cultivars is based on the characterization of genotype × environment interaction, which is interpreted to quantify the differential behavior of clones at different cultivation sites. The objective of this research was to study the genotype x environment interaction aiming to select clones of broad and specific adaptation to different environments of the Western Amazon. Twelve clones with hybrid characteristics of the botanical varieties Conilon and Robusta and four open pollinated clones, had their performance evaluated in comparison with four controls. The genotype × environment interaction was interpreted based on the environmental quality index, the non-parametric estimator of Lin and Binns, 1988 and on the... |

| RESUMO: O nitrogênio (N) é um dos macronutrientes mais exigidos pelo cafeeiro. Sua utilização é necessaria para o cultivo nos solos de cerrado, pois estes não fornecem o nutriente em quantidades suficientes. Foi realizado um ensaio com o objetivo de estudar o efeito de fontes e doses de N no café decotado a 1,5 m de altura em 1997. O experimento foi instalado num Latossolo Vermelho na área experimental da Embrapa Cerrados, em Planaltina -DF. Os tratamentos foram constituídos de 0, 200, e 600 kg ha-¹ de N na forma de uréia parcelados em frações de 1/4, 1/2 e 3/4 no primeiro ano e em 3/4, 1/2 e 1/4 fornecidos no segundo ano e repetidos respectivamente, no terceiro e quarto anos. Foram também acrescidos dois tratamentos, 100 kg N ha-¹ na forma de uréia... |

| The objective of this work was to evaluate the agronomic traits of coffee tree progenies. The experiment was set in Ouro Verde Farm, located at Campos Altos County, MG. Twenty three coffee progenies and seven control cultivars were used. These progenies are from the fourth generation of crossing between Timor Hybrid and Catuaí. The experiment was set in a randomized block design with four replicates, a total of 120 plots with 8 plants per plot. The yield of processed coffee sacks ha-1 was evaluated in eight crop years from the 2003 to the 2011 harvests. The percentage of fruits at the cherry stage, floating fruits, coffee classification (sieve above 17), income and plant vigor were evaluated in the 2010 and in the 2011 harvests. It was concluded that the... |

| Three degrees of red mite infestation (Oligonychus ilicis McGregor) (Acari: Tetranychidae) were evaluated with regard to leaf anatomy, photosynthetic gas exchange and leaf ethylene production, in a commercial crop of approximately 12-year-old trees of Coffea arabica 'Catuaí Vermelho'. As a complementary study, foliar anatomy was also evaluated in a recuperated crop of C. arabica 'Mundo Novo' that had presented a high degree of red mite infestation during the dry period of the prior growing season. The red mite-infested leaves were bronze-coloured, with intensity proportional to the degree of internal damage. On feeding, the red mite introduces its stylet in the adaxial epidermis and, as a result, chloroplasts are destroyed in the feeding area. The number... |

| The coffee is one of the most important products in the economy of Minas Gerais. In some specific places it has a great importance in the local production, but in any place the economic players involved in that market have the same trouble: the share of risk taken by them. Therefore, would be really important, and useful, to calculate the risk share of each player. Than, this article showed the risk amount absorbed by the players in the coffee market of Minas Gerais, based in the prices paid in the south of that state, the greatest region producer, trough two models of Value at Risk (VaR), the Normal Model and the Historic Simulation Model. The results shows a risk absorbed about 17,28%, with 95% of sure, and 24,60% with 99% of sure, both of them in a... |

| The objective of this work is to analyze coffee production and processing in the economic structure of Minas Gerais, to determine its importance and its linkages to the structure of the State economy, by using input-output matrix. Therefore, it is determined linkages indexes of Rasmussen-Hirschman, boarding fields, pure linkage index (GHS) and regional multipliers of product, income and employment. These applications are complementary to the identification of key sectors of the economy. The 1995 input-output matrix was used. Linkages indexes of Rasmussen-Hirschman and the analysis of the influence field pointed out that coffee production presents multiplying indicators above those of the economy, presenting higher backward and forward linkages. The coffee... |

| ABSTRACT The benefits of mycorrhization occur with the growth of hyphae in colonized roots by promoting an increase of the contact surface which improves the initial growth due to a better absorption of water and nutrients. The objective was to evaluate the effect of arbuscular mycorrhizal fungus Rhizophagus clarus inoculation over the initial development and nutritional response of six genotypes of Coffea arabica L. Six genotypes of Coffea arabica L. were used (MGS Aranas, H29-1-8-5, Red Catuai IAC 144, IPR 100, Catigua MG2, Paraíso H 419-1) and with arbuscular mycorrhizal fungus - AMF: Rhizophagus clarus and without the application of the fungus. For the production of coffee seedlings, seeds were placed to germinate in plastic trays with sterile sand.... |

| The commodity nature of green coffee is the main cause of “the coffee paradox” (decreasing prices at production level and rising prices at consumption level). So, a requirement to reach a less unfair distribution of the added value between the supply chain would be to “decommodify” the coffee market not only at the final consumer level, but also at the production level. Certifications (like Fair Trade, Organic, Rainforest Alliance, Utz Kapeh, or Birdfriend) are often presented as a way to reach this result, but according to some authors these schemes seem to be rather an extension of the standardization wave to new quality attributes (linked to social and/or environmental characteristics of the production process). Geographical indications (GIs) seems to... |
