Santos Júnior, Nilson érito Timóteo dosCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Potato is an important food source for the world, and to evaluate the effect of the percentage of potassic sources (double sulphate of potassium and magnesium and potassium chloride) Atlantic cultivar, the experiment was conducted in Whermann farm, located in Cristalina-GO, from 19 July to 19 November 2011. The experimental design was a randomized blo...
Validação de métodos para teste de germinação em sementes de espécies florestai...
Pereira, Vanderley JoséConselho Nacional de Desenvolvimento Científico e Tecnológico; CHAPTER II: The standardization of inter-laboratory results of germination test of forest species seeds requires that the methods be robust and subject to low variability. Therefore, the objective was to compare and discuss different forms of the coefficient of variation for normal seedlings in the method validation process for testing germination o...

Oliveira, Valécia Martins deCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Soybean is a central culture whose grain productivity stands out thanks to advances in genetic improvement. The aims recommended to soybean improvement include reaching high grain productivity, stability and adaptability to diverse environments. The research this study presents aimed at studying genotype environment interaction in regard to grain prod...
Repetitividade e reprodutibilidade na validação de métodos para testes de germi...
Brandão, Núbia Almeida LeiteFundação de Amparo a Pesquisa do Estado de Minas Gerais; In the process of method validation, the International Association for Seed Analysis quantifies repeatability and reproducibility by lot. However, this process for seed analysis is defined by a analysis of variance model with two factors, and an R&R study is recommended. Regardless if estimated by lot or by factorial analysis of variance model, repeatabil...
Correlações entre caracteres como critério de seleção indireta, adaptabilidade ...
Bisinotto, Fabiano FariaSoybean [Glycine max (L.) Merrill] is a Fabaceae, which comes from China. Currently, it is widely grown in the world and in Brazil, as it is a source of oil and protein, very important in feeding in general. It is a valued product in commerce, considered a commodity. Soybean breeding programs are to obtain highly productive cultivars, associated with other features of interest, such as agronomic characters, res...
Variabilidade espacial de atributos do solo e emissão de CO2 em uma pedossequên...
Mikhael, Joseph Elias RodriguesFundação de Amparo a Pesquisa do Estado de Minas Gerais; Precision Agriculture is a tool available to the producer that allows visualization of the spatial variability of edaphoclimatic factors in each agricultural area, considering the peculiarities of each one at the management time. The change from a purely descriptive phase of geological phenomena to a quantitative approach is remarkable. This process of tr...
Tratamento de semente de milho com suspensão concentrada à base de zinco
Bonotto, IvanThe perspective for maize are very encouraging, in view of the global needs for food, feed, and more recently, for clean energy. The Brazil is the third in this cereal production among the U.S.A and China and has high potential for growth in production, with the following advantages, such as production area, available water, potential to produce two annual crops, research institutes, etc. However, it is estimat...
Modelagem geoestatística de nematoides, argila e atributos químicos do solo em ...
Pimentel, Reinaldo RodriguesCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; This study evaluated the spatial distribution of nematodes, clay content and soil chemical properties with the aid of geostatistics in an area mostly cultivated with soybeans. For this, georeferenced samples of soil and roots, from a rural property in Paracatu MG, were collected and subjected to chemical, physical and nematode analyses. Sampling was c...
