Remote Detection of water and nutritional status of soybeans using UAV-based images. Digital aerial images obtained by cameras embedded in remotely piloted aircraft (RPA) have been used to detect and monitor abiotic stresses in soybeans, such as water and nutritional deficiencies. Thi... ... Repository: BDPA Publication year: 2022
Discriminação de sistemas de produção em pecuária por meio de EVI-2 derivado do sensor worldview-2. O objetivo deste trabalho foi testar o potencial de discriminação do índice de vegetação Enhanced Vegetation Index-2 (EVI-2), derivado de uma imagem de alta resolução WorldView-2, na avaliação de 11 t... ...

Prediction of aboveground biomass and dry-matter content in brachiaria pastures by combining meteorological data and satellite imagery. Aboveground biomass (AGB) data are important for profitable and sustainable pasture management. In this study, we hypothesized that vegetation indexes (VIs) obtained through analysis of moderate spati... ... Repository: BDPA Publication year: 2021
Poda mecanizada na macieira e seus efeitos no Índice de Vegetação por Diferença Normalizada (NDVI). A poda é um dos principais tratos culturais na cultura da macieira (Malus domestica), sendo responsável por potencializar e regular seu rendimento ao longo das safras. Neste estudo, buscou-se avaliar... ... Repository: BDPA Publication year: 2024
Understanding the land surface phenology and gross primary production of sugarcane plantations by eddy flux measurements, MODIS images, and data-driven models. Abstract: Sugarcane (complex hybrids of Saccharum spp., C4 plant) croplands provide cane stalk feedstock for sugar and biofuel (ethanol) production. It is critical for us to analyze the phenology and... ... Repository: BDPA Publication year: 2020
