25. Cost efficiency of cryopreservation as a long-term conservation method for coffee genetic resources.
Coffee (Coffea spp.) is one of the world?s most valuable agricultural export commodities produced by small-scale farmers. Its germplasm, which holds useful traits for crop improvement, has traditionally been conserved in fi eld genebanks, which presents many challenges for conservation. New techniques of in vitro and cryopreservation have been developed to i

27. Comparação e desenvolvimento de metodologias para o controle de qualidade de inoculantes / Comparison and development of methodologies for inoculants quality control
Inoculants containing N-fixer microorganisms generate huge economy for agricultural systems with nitrogen fertilization. In order to make inoculant products reach the market with the minimum attributes established in legislative determination, it is necessary to perform a good quality control. Therefore, this study aimed to compare methods of analysis of leg

28. Controle de Sitophilus zeamais (Coleoptera: curculionidae) em variedades de milho crioulo com uso de plantas inseticidas
Os cereais representam 90% dos grãos produzidos no mundo e são a principal fonte de alimentos para os seres humanos e animais de criação. Entre os cereais, o milho é a agricultura mais difundida e cultivada no mundo, devido à sua capacidade de adaptação aos mais diferentes ecossistemas. A manutenção da qualidade do grão de milho após a colheita �

29. Propagação in vitro de Anacardium othonianum rizz., uma espécie frutífera e medicinal do cerrado / In vitro propagation of Anacardium othonianum rizz., a savannah fruiting and medicinal species
Anacardium othonianum Rizz., known as caju de árvore do cerrado, is a fruiting and medicinal species native of the savannah ecosystem, with great economic potential. Since agricultural expansion in the savannah was followed by the reduction of native vegetation, micro propagation has significantly contributed for the propagation of several species, resultin

30. La geología, geomorfología, pedología y uso de la tierra en las municipalidades de Puerto López (Colombia) y Uberlândia (Brasil)
On account of the precaution to raise the quality of life for people in Brazil and Colombia, isolated studies were developed to know the main human and physical resources and thus establish standards for proper management and exploitation of the territory. The aim of this study was to map and compare the geology, geomorphology, soils and land use and natural

31. Desempenho de diferentes estrategias de aeração de milho armazenado / Performance of different aeration strategies for stored corn
The efficiency of grain storage doesn t consist only to "save" the agricultural production, but mainly to avoid the problem with the moisture migration, incidence of insects and development of microorganism in grains, during the process. Aeration is currently used for reducing and homogenization the intergranular temperature, aiming to minimize these problem

33. TEMPERATURE AND HUMIDITY OF A SANDY LOAM SOIL CULTIVATED WITH MAIZE / TEMPERATURA E UMIDADE DE UM SOLO FRANCO ARENOSO CULTIVADO COM MILHO
Water is a key factor for crop yields, and causes major fluctuations in productivity, especially for maize cultivated in southern Brazil. Mulching the soil surface, temperature and soil moisture are factors closely linked and, when handled properly, can provide the increases crop yields. The soil water conservation is an important aspect for more stable and
