Ocorrência de plantas daninhas em cultivo consorciado de café e nogueira-macadâmia

Arborization can benefit coffee plantations by reducing the wind speed and temperature variation in the crop. It is also possible that the incident radiation can affect the weed populations and reduce the need for their control. This study aimed at assessing the weeds population and distribution, in arabica coffee intercropped with three macadamia cultivars, six years after planting, in Dois Córregos, São Paulo State, Brazil. Treatments consisted of a 3x3+1 factorial scheme, i.e., coffee intercropped with three macadamia cultivars (HAES 816, IAC 4-20 and IAC 9-20) and three sampling positions of weeds in the intercropping (in the macadamia tree canopy projection, among the macadamia tree canopies projections and in the single rows), plus an additional treatment (sole coffee). The weeds incidence and control, as well as their phytosociological characterization, were evaluated. For coffee intercropped with macadamia, the weeds occurrence and number of species were smaller than for sole coffee. For the projection in the canopy and among canopies of macadamia trees, there was an average decrease of 82% in the occurrence of weeds, in comparison with the sole coffee. The IAC 9-20 cultivar was more efficient in reducing the occurrence of weeds, when intercropped with coffee, for presenting a taller canopy, with a larger diameter.

Cobertura e depósito de calda fitossanitária em plantas de café pulverizadas com equipamento original e adaptado para plantas altas

The objective of this study was to evaluate the coverage of spray droplets on coffee plants as well as their deposition using a sprayer with and without adaptation of an auxiliary branch for tall plants. The experiment was conducted following a randomized block design with six treatments and four replications to evaluate the percentage of coverage for the spraying liquids in water sensitive paper fixed at four quadrants and two heights (lower and upper) of the plants, and the spray deposit with metallic marker (MnSO4) on sheets in the same positions of the water sensitive paper in two spray volumes (450 and 750 L h(-1)). The experiment was conducted in October 2011 in the town of Patroc nio-MG, and the experimental plots consisted of 30 plants of Catua IAC-99, with approximately 12 years of age and average height of 3.50 meters. The experiments were conducted following a randomized block design with six treatments and four replications to evaluate the coverage and deposition, in two spray volumes (450 and 750 L ha(-1)). Leaves were collected in four positions and also at the top four in the lower canopy. The results of the evaluations were analysed statistically by F test and for comparison of means by Tukey test at 5% probability. The auxiliary branch installed at the rear of the equipment is the most suitable when compared to use of equipment without this feature or installed in the front of the equipment. Furthermore, the application volume of 450 L ha(-1) results in coverages and deposits of spraying liquids equivalents to volume of 750 L ha(-1), considered sufficient according to the parameters evaluated.

Recuperação de áreas degradadas por erosão hídrica em propriedades produtoras de café nos municípios de Getulina e Vera Cruz - SP

The Paulista West region has suffered through the decades an intense process of deforestation when substituting native areas of Atlantic rainforest and Cerrado by agricultural cultivation, mainly coffee in the 20th century. This occupation process without planning and management of the soil resulted in serious erosion problems. Besides, the soil erosion promoted the reduction of agricultural production and the silting of rivers. This paper aims identify the factors of natural scope (geological, geomorphologic and pedologic characteristics) which participate in unleash of erosion process in two agricultural properties producers of coffee in order to apply mechanical techniques of recovery in erosive focuses of furrow and ravine kinds. One of the properties is at the city council of Getulina, located on the sandstones of Adamantina Formation; the other is at the city council of Vera Cruz, located on the sandstones of Marília Formation. However, taking into consideration the analysis of the natural dynamics, they are not enough to explain the complexity of the phenomena which are processed in the geographic space. It made indispensable the incorporation of socio-economic factors, such as the use and occupation process of the soil considering the society as landscape transformers. In order to better understand the importance of each one of the elements that contributes to the unleash of the studied erosions, it was collected soil samples in the areas, general descriptions and texture and morphologic analysis. Finally, it was elaborated the maps of the use and occupation of the soil and the vegetal coverage surrounding the properties studied. It was observed in the rural property of Getulina the substitution of the coffee by pasture that finds degraded. It, in addition to the cattle stomp, which changed the texture and density characteristics among the soil horizons, and the concentration of superficial water flow intensified the occurrence of ...

Circuito espacial produtivo e círculos de cooperação dos café Fairtrade: análise da Associação dos Agricultores familiares do Córrego D'Antas (ASSODANTAS), Poços de Caldas/MG

The aim of this research project is to analyze the spatial productive circuit and circles of cooperation of Fairtrade coffee, taking as a case of study the Associação dos Agricultores Familiares do Córrego D'antas (ASSODANTAS), Poços de Caldas - MG. The main purpose is to analyze material flows (grains, supplies, etc.) established between geographically separated stages of production (production, exchange, distribution and consumption) and the relationships between the agents in order to analyze the organization and regulation of production of Fairtrade coffee. It is understood as the insertion of the Fairtrade ASSODANTAS to permit the creation of new production lines, adding value and providing greater identity and autonomy to their small farms, when compared with traditional coffee trade commodity

Amplificação, clonagem e sequenciamento de promotores de café (Coffea arabica cv Mundo Novo) específicos de fruto e ubíquos

The Coffee Genome Project made available to the scientific community relevant information that made practical the identification and cloning of important genes, as well as the identification of the major sequences involved on their regulation. The aim of the present study was to amplify, clone and sequence coffee promoters with specific expression patterns. For that, coffee ESTs which known expression profiles were employed. First, the promoter regions of coffee genes showing, respectively, fruitspecific and ubiquitous expression were amplified using the Genome Walking strategy. Amplified sequences were then inserted in the pGEM-Teasy vector (Promega) and sequenced. Once completed the sequencing, an expression cassette was constructed using the binary vector pCAMBIA-1381z (Cambia). These expression cassettes were cloned into Agrobacterium tumefaciens, and transgenic tobacco plants were generated aiming the functional characterization of these promoters

Regiões competitivas agrícolas e vulnerabilidade territorial: o papel do Consórcio Pesquisa Café

This academic work presents the final results of the undergraduate research about new agricultural technical systems developed by “Consórcio Pesquisa Café” (CPC), which main objective was to analyze the impacts of scientific inputs in different coffee producing regions, particularly in South of Minas Gerais. The creation of the CPC meets the demands of a global scientific coffee-growing (SANTOS, 2000) under development in the current period technical-scientific-informational (SANTOS, 2009). On this period, also called globalization, the technoscience, the information and the finances guide the actions of companies and institutions submitted by imperative of competitiveness on international market. The Brazilian’s coffee-growing regions (South of Minas Gerais, Cerrado Mineiro, Espírito Santos Ridge’s, Western Bahia, among others) on search of higher productivities, begin gather technical, informational and communicational densities (SANTOS, 2009). Considering these facts, we detail in this research, the major agricultural technical systems developed by “Consórcio Pesquisa Café” (CPC), expressed in new management techniques, new cultivars and new chemicals, mechanical and biological inputs. In the concluding part of this undergraduate research we analyze how these new technical systems contribute to increased competitiveness and vulnerability of South of Minas Gerais in front of international market
