1. Consumptive water use of banana under micro irrigation using a soil-water balance approximation
RESUMO A cobertura do solo contribui para a manutenção do teor de água do solo em níveis razoáveis para o crescimento da cultura. E influi na demanda hídrica da cultura e tempo de irrigação. O objetivo deste estudo foi estimar a evapotranspiração e a absorção de água radicular pela cultivar de bananeira ‘BRS Princesa’ através de uma abordag

2. APPLICABILITY OF THE SWAT HYDROLOGICAL MODEL IN THE MUCURI RIVER BASIN
ABSTRACT Land-use changes promote significant variations in streamflow regimes, and hydrological models allow studying their impacts. Based on this approach, this study aimed to assess the applicability of the SWAT model for different land-use scenarios and their respective impacts on the flow regime of the Mucuri River. The average monthly and daily water b

3. MODELING YIELD, SOIL WATER BALANCE, AND ECONOMIC RETURN OF SOYBEAN UNDER DIFFERENT WATER DEFICIT LEVELS
ABSTRACT Evaluating the impacts of water stress on crop yield allows comparing irrigation management alternatives, aiming to ensure an economic return for the irrigated farms. Thus, the main objectives of this study were to model the soil water balance, deriving the crop coefficients, grain yield prediction, and economic return of soybean grown at different

4. INFLUENCE OF SOIL TEXTURE, CLIMATE AND VEGETATION COVER ON SECONDARY SOIL SALINIZATION IN PAMPAS PLAINS, SOUTH AMERICA
ABSTRACT Land-use change from herbaceous to woody cover -or vice versa- largely affects water fluxes, which in turn can mobilize existing salts dissolved in the soil, and thereby negatively affect soil and/or water quality and site productivity. Secondary salinization was observed after afforestation at the Northern and Eastern subregions of the Río de la P

5. Soil water storage variability in a three-dimensional analysis in the root zone of irrigated melon
ABSTRACT A detailed knowledge of the soil water storage variability in the root zone can promote recommendations regarding the ideal positioning of sensors, as well as make the calculation of soil water balance more precise and accurate. This study aimed to assess soil water storage variability in the melon root zone and indicate – based on spatial variati

6. Physiological responses of Eucalyptus urophylla young plants treated with biostimulant under water deficit
Resumo Os bioestimulantes consistem em uma mistura de reguladores de crescimento que, quando aplicados nas plantas, atuam no equilíbrio hormonal, melhorando seu desenvolvimento. Stimulate® é um bioestimulante composto por ácido indolbutírico (0,005%), cinetina (0,009%) e ácido giberélico (0,005%), que promove o crescimento das raízes, melhora a absor

7. Water balance in soil covered by regenerating rainforest in the Paraíba Valley region, São Paulo, Brazil
Resumo Objetivou-se avaliar o balanço hídrico em Latossolo Vermelho-Amarelo coberto por floresta tropical em regeneração há 30 anos, na bacia do rio Una entre abril de 2016 e março de 2017. Os valores da capacidade de campo (FC) e ponto de murcha permanente (PWP) usados para calcular a capacidade de água disponível (AWC) no solo foi determinado pela

8. Land use and water quality in watersheds in the State of São Paulo, based on GIS and SWAT data
Resumo O uso e ocupação do solo influenciam a qualidade e a disponibilidade de água, devendo ser considerados numa gestão integrada dos recursos hídricos e no planejamento das bacias hidrográficas. Ferramentas de geoprocessamento têm sido utilizadas para classificação do uso do solo e combinadas com modelos hidrológicos para avaliação do impacto

9. Analysis of Infestation of Nematode Meloidogyne exigua in a Rubber Tree Plantation in the Triângulo Mineiro Region
ABSTRACT This study analyzed the use of the water balance, precipitation, temperature and NDVI (Normalized Difference Vegetation Index) to determine the optimum moment for evaluating infestation by the nematode Meloidogyne exigua in a rubber tree plantation by remote sensing. Nineteen sampling points were defined, divided into three areas, with high and low

10. Analysis of the effect of impermeability of urban soils on the infiltration of rainwater in the city of Recife, PE
Resumo O processo de urbanização interfere nos elementos do ciclo hidrológico, alterando as características de infiltração, escoamento e evaporação da água oriunda da chuva. Para analisar este ciclo hidrológico há diversos métodos e ensaios que visam caracterizar hidrodinamicamente o solo de uma localidade. Entretanto, a realização de coletas e

11. Elevated atmospheric CO2 concentration improves water use efficiency and growth of a widespread Cerrado tree species even under soil water deficit
ABSTRACT Changes in atmospheric CO2 levels are accompanied by ecological interactions involving other environmental factors, such as drought, which can severely alter the water balance of plants, thereby influencing sap flow, gas exchange, and plant growth. The objective of this study was to evaluate the water use economy, leaf gas exchange, and growth of yo
