1. Suitable weather condition frequency for fungicide soybean application in Tangará da Serra, Mato Grosso, Brazil
ABSTRACT The aim of this study was to model the decendial and hourly variability of meteorological variables, namely air temperature, relative air humidity and wind speed, in the Tangará da Serra region, Mato Grosso, Brazil, to determine the best schedules for fungicide applications to soybean crops. Hourly weather data between 2004 and 2017 from the Tangar

2. Modeling hourly air temperature based on internationally agreed times and the daily minimum temperature
RESUMO Existem áreas que exigem conhecimento da variação da temperatura do ar ao longo do dia, como previsão de doenças ou cálculo de horas de frio. Porém, nem sempre há estações meteorológicas automáticas próximas para observar esta variável. Nesse sentido, modelos que descrevem a variação temporal diária da temperatura do ar podem ser util

3. Dados de estação meteorológica oficial subestimam o estresse por calor em bovinos leiteiros criados em ambiente tropical
RESUMO Determinaram-se os valores de temperatura do ar, umidade relativa e índice de temperatura e umidade (ITU) de uma propriedade rural de produção de leite a pasto e da estação meteorológica oficial mais próxima, confrontando-os. Na fazenda, as leituras dos dados foram registradas por uma estação meteorológica automática, a cada cinco minutos,

4. Simulation of Flow in the Capim River (PA) using the SWAT Model
ABSTRACT Flow in the Capim River watershed, located in the state of Pará, Brazil, was estimated using the Soil and Water Assessment Tool (SWAT) model in order to determine its use efficiency. The meteorological data (from 2000 to 2010) were collected from an automatic station located in the municipality of Paragominas. The pluviometric and fluviometric dat

5. TIME AVAILABLE FOR SPRAYING AND MECHANIZED SOWING IN THE NORTHEAST OF THE STATE OF MATO GROSSO DO SUL AND SOUTH OF GOIÁS
ABSTRACT The sizing of mechanized agricultural systems depends on the soil and climatic conditions, the crop and the work regime. The aim of this study was to determine the probabilities of time available during an agricultural year for mechanized spraying and sowing in the northeast region of the State of Mato Grosso do Sul and south of Goiás. The meteorol

6. Chemical composition and photosynthetically active radiation of forage grasses under irrigation
The present study aimed to estimate the photosynthetically active radiation of tropical forage grasses in ten cutting dates, under irrigation. The following treatments were used: Brachiaria decumbens grass (Brachiaria decumbens cultivar Basilisk), Marandu grass (Brachiaria brizantha cultivar Marandu), Xaraes grass (Brachiaria brizantha, cultivar Xaraes), Mom

7. Desenvolvimento e avaliação de uma estação meteorológica automática para manejo de irrigação / Development and evaluation of an automatic meteorological station for irrigation management
Devido ao crescente aumento populacional mundial, a agricultura irrigada é uma importante estratégia para maior produção de alimentos, fibras e agroenergia. A determinação da lâmina de irrigação por meio de estudos da evapotranspiração da cultura (ETc) tem sido uma tecnologia amplamente divulgada e utilizada em razão da sua operacionalidade. Para

9. EMISSÃO DE GASES DE EFEITO ESTUFA EM SISTEMAS DE MANEJO EM SOLO DO PLANALTO MÉDIO DO RIO GRANDE DO SUL / SHORT-TERM GREENHOUSE GASES EMISSIONS IN SOIL MANAGEMENT SYSTEMS IN OXISOL OF SOUTHERN BRAZIL
Agriculture is directly linked to atmospheric concentration of greenhouse gases (GHG) through basic processes that occur in the soil-plant system. Agricultural soils can act as a source or sink of GHG depending on the management practices adopted. The objective of this research was to evaluate the GHG flux in different soil management systems. This project w
