| Abstract | Uma variação significativa na produção de trigo é observada em condições de campo devido aos efeitos climáticos, genéticos e agronômicos que nem sempre estão relacionados com a informação contida nas imagens de satélites de sensoriamento remoto. O avanço tecnológico, na área de sensoriamento remoto, tem propiciado o surgimento de radiômetros hiperespectrais que operam na faixa de comprimento de onda de 400 a 2500 nm, o que possibilita obter medidas de reflectância de dosséis agrícolas em condições de campo a fim de permitir um melhor entendimento sobre as relações entre o comportamento espectral e variáveis biofísicas de culturas agrícolas. Neste sentido, foi instalado um experimento, na fazenda experimental do Instituto Agronômico em Campinas-SP, Brasil, com quatro genótipos de trigo, submetidos a cinco doses de nitrogênio (0, 30, 60, 90 e 120 kg ha-1). O objetivo da pesquisa foi estudar o comportamento espectral do trigo por meio de simulação das bandas do sensor TM do Landsat-5 e dos índices de vegetação NDVI e SAVI. Além disso, fez-se uma análise da correlação da radiação fotossinteticamente ativa absorvida acumulada ( e da eficiência do uso da radiação com a produção de grão (G) e a altura das plantas. As medidas radiométricas foram obtidas com o radiômetro FieldSpec FR PRO, que opera na faixa de comprimento de onda de 350 a 2500 nm. Os resultados mostraram que não houve diferenças significativas no comportamento espectral dos genótipos. No entanto, a análise de profundidade de banda da absorção da clorofila mostrou que houve diferença significativa para o comprimento de onda de 675 nm, o que justificou a diferença observada na e na G. ABSTRACT A significant variation in wheat production is observed under field conditions due to climatic, genetic and agronomic effects that are not always related to information contained in remote sensing satellite images. Technological advancement in the remote sensing area has promoted the appearance of hiperspectral radiometers operating in the wavelength range of 400 to 2,500 nm and made it feasible to obtain reflectance measurements of agricultural canopies under field conditions in order to allow a better understanding of the relationship between spectral behavior and biophysical variables of agricultural crops. Thus, a field experiment was carried out in the experimental farm of the Agronomic Institute at Campinas, São Paulo State, Brazil, with four wheat genotypes, submitted to five Nitrogen doses (0, 30, 60, 90 and 120 kg ha-1). The objective of this research was to study the spectral behavior of wheat through the band simulation of Landsat-5 TM sensor and vegetation indices NDVI and SAVI. Furthermore, a correlation analysis was performed with the accumulated absorbed photosynthetically active radiation and the radiation use efficiency (G) with grain yield and plant height. The radiometric measurements were acquired with the FieldSpec FR PRO that operates in the wavelength range of 350 to 2,500 nm. The results showed that no significant differences were observed for the spectral behavior of the genotypes. However, the analysis of the absotion band for chlorophyll absorption showed a significant difference for the wavelength of 675 nm, which explained the difference observed for and for (G). |
