| The poultry litter keeps the birds comfortable and absorbs the humidity generated in the environment, reducing the feet injuries. Then, its quality is essential. The objective for carrying out the present study was to evaluate the quality of the coffee husk poultry litter, treated with chemical additives, based on its humidity, N-ammonia, pH and bacteria total counting. The experiment was carried out in Minas Gerais state, Brazil, in a coffee producer region. It were used three facilities, in which it were placed circular boxes, each of them divided in seven parts, 2 m2 each one, where it were put the different types of poultry litter, being these the seven treatments: sawdust and coffee husks litter, being this last, new and untreated or treated with... |

| Studies testing the High Energy Moisture Characteristic (HEMC) technique in tropical soils are still incipient. By this method, the effects of different management systems can be evaluated. This study investigated the aggregation state of an Oxisol under coffee with Brachiaria between crop rows and surface-applied gypsum rates using HEMC. Soil in an experimental area in the Upper São Francisco region, Minas Gerais, was studied at depths of 0.05 and 0.20 m in coffee rows. The treatments consisted of 0, 7, and 28 Mg ha-1 of agricultural gypsum rates distributed on the soil surface of the coffee rows, between which Brachiaria was grown and periodically cut, and compared with a treatment without Brachiaria between coffee rows and no gypsum application. To... |

| The objective of this article was to analyze the managerial styles in coffee farmers of two regions in Minas Gerais State, Brazil (Sul and Zona da Mata), and the difficulties which can be compromising the administrative effectiveness. Primary data were collected from forms applied to 56 coffee farmers, in the harvest period 2003/2004. To analyze the relation between the dominant managerial styles and the reached economic and technical performances in the activity, the analysis of simple correlation was used (coefficient of Pearson). Regressions were estimated to indicate as the situational variables had intervened in the styles. Among the main results it is important to point out that the producers, in general, presented as dominant managerial style 9,9,... |

| Recent studies on coffee (Coffea arabica L.) cultivation in agroforestry systems in Southern Brazil have shown the potential of partial shading to improve management of this crop. The objective of this work was to evaluate microclimatic conditions and their effects on coffee production of plants shaded with pigeon pea (Cajanus cajan) in comparison to unshaded ones, from May 2001 to August 2002 in Londrina, State of Paraná, Brazil. The appraised microclimatic characteristics were: global radiation, photosynthetic and radiation balance; air, leaf and soil temperatures; and soil humidity. Shading caused significant reduction in incident global solar radiation, photosynthetically active radiation and net radiation, and attenuated maximum leaf, air and soil... |

| ABSTRACT The objective of this study was to evaluate the performance of a variable-rate fertilizer distribution system for coffee crop, simultaneously applying two products. Two types of tests were performed: transversal deposition and longitudinal deposition. The transversal deposition test, with tarps, aimed to quantify the variations between programmed and applied doses, using a completely randomized design (CRD), in a factorial scheme, and the Scott-Knott test at p < 0.05. The longitudinal deposition test aimed to determine the distribution characteristics of the equipment along the displacement line, based on relative frequency values. In addition, the application rates on both sides of the distribution system were analysed using a CRD and the... |
