Using Remote Sensing to Quantify the Joint Effects of Climate and Land Use/Land...
Jardim, Alexandre Maniçoba da Rosa Ferraz; Araújo Júnior, George do Nascimento; Silva, Marcos Vinícius da; Santos, Anderson dosCaatinga biome, located in the Brazilian semi-arid region, is the most populous semi-arid region in the world, causing intensification in land degradation and loss of biodiversity over time. The main objective of this paper is to determine and analyze the changes in land cover and use, over time, on the biophysical parameters in the Caatinga biome in the semi-arid region of Brazil using remote sensing. Landsat-...

No. of bitstreams: 0 Previous issue date: 2021-03-01; The current challenge of corn (Zea mays L.) crops is to reach high yield to supply the world's demand for food, especially under different fertilization regimes and using the latest technology. We hypothesized that wavelengths and vegetation indices have a linear relationship with agronomic variables in...

No. of bitstreams: 0 Previous issue date: 2021-08-01; Carrying out monitoring during the crop cycle through vegetation indices (VIs) with obtained unmanned aerial vehicle allows agility in decisions about management practices, as well as concerning nutritional deficiencies in crops, as nitrogen (N). This nutrient absorbed in greater quantity, and that most...
Phenotypic adaptability of cotton genotypes to the brazilian cerrado for yield ...
Cotrim, Mayara Fávero; Farias, Francisco José Correa; Carvalho, Luiz Paulo de; Teodoro, Larissa Pereira Ribeiro; Silva Junior, Carlos Antonio daStudies on the adaptability and stability are fundamental for plant breeding as they are an alternative to reduce the effects of genotypes x environments interaction (GxE). Moreover, they help identify cultivars with predictable behavior, which are responsive to environmental improvements, subsidizing cultivar recommendation. This study aimed to investigate the genotypes x environments interaction in cotton gen...

No. of bitstreams: 0 Previous issue date: 2020-03-01; Brazil has the largest commercial beef cattle stock on Earth, and most of the cattle produced in the country is bred and finished on pastures. The cattle ranching sector represents a significant source of the country's greenhouse gas (GHG) emissions. Agricultural intensification has been highlighted as ...
Space-time variability of the Roncador river basin in the change of land use an...
Santos, Raquel de Oliveira; Delgado, Rafael Coll; Pereira, Marcos Gervasio; Souza, Leonardo Paula de; Teodoro, Paulo EduardoThe objective of this study was to evaluate the space-time dynamics of the soil use and occupation of the Rio Roncador river basin between 1985 and 2010. The scenes were classified by two methods (partially unsupervised - K-Means and supervised - Maximum likelihood), the Thematic Mapper sensor products on the LANDSAT 5 orbital platform were used for both images of a 25-year time series (1985 to 2000). In order ...

Facco, Cassiele Uliana; Andrade, Carlos Alberto de Bastos; Silva, Guilherme Fernando Capristo; Silva Junior, Carlos Antonio daThe growing quest for sustainability in agricultural production systems has been pushing researchers to develop new technologies under different soil and climatic conditions. Based on this, and knowing the socioeconomic importance of the bean, the use of biological nitrogen fixation (BNF) is explored. Thus, the quest for quantitative knowledge of BNF at the phenological stages in a new bean line using promising...

de Jesus, Carolina Souza Leite; Delgado, Rafael Coll; Pereira, Marcos Gervásio; Souza, Leonardo Paula de; Silva Junior, Carlos Antonio daThe objective of this study was to perform a temporal and spatial analysis of the changes in the past global solar radiation based on climate models and remote sensing data in the State of Rio de Janeiro, Brazil for the baseline period (1961-1990). Data from two climate models - the Canadian Centre for Climate Modelling and Analysis and Geophysical Fluid Dynamic Laboratory, were used for the A1B intermediate sc...
Probable monthly rainfall associated with distinct biomes of Mato Grosso do Sul...
Teodoro, Paulo Eduardo; Silva Junior, Carlos Antonio da; Oliveira-Junior, José Francisco; Delgado, Rafael Coll; Gois, Givanildo deThe aim of this study was to determine the probable monthly rainfall for the state of Mato Grosso do Sul, considering the level of 75% probability, and study the spatial distribution associated with its different biomes. The rainfall data of 32 stations (sites) in the state of Mato Grosso do Sul were collected in the period 1954-2013. In each of the 384 series, the average monthly rainfall was calculated, for a...
