“…The overflight was performed at 100 m asl, allowing a spatial image resolution of 0.10 m. After obtaining the wavelengths, NDVI, NDRE, GNDVI, and SAVI were calculated. These procedures were performed according to Silva et al (2020). The agronomic traits evaluated were plant height (PH, m), first cob height (FCH, m), stem diameter (SD, cm), cob length (CL, cm), number of rows per cob (NRC), number of grains per row (NGR), and grain yield (YIE, kg ha −1 ).…”

“…This demonstrates that the VI’s evaluated here can be used as an auxiliary approach for evaluating the performance of soya bean plants submitted to different base saturation levels in the soil. VI’s have been used even during the crop development cycle aiming at obtaining additional information about its nutritional status, as well as its yield potential (Da Silva et al., 2020; Osco et al., 2020; Ramos et al., 2020).…”

“…The broad diversity of remote sensors enables capturing different aspects of the plant phenotype. Different combinations of RGB, multispectral, and thermal image data associated with weather and soil have been employed to train deep learning models for crop yield forecasting ( Vega et al, 2015 ; Gracia-Romero et al, 2019 ; Zhang et al, 2019a ; Maimaitijiang et al, 2020 ; da Silva et al, 2020 ). The models can support differentiating crop performance in relation to irrigation regimes ( Gracia-Romero et al, 2019 ), quantify growth rate under nitrogen treatment ( Holman et al, 2016 ; Arroyo et al, 2017 ; Aranguren et al, 2020 ), estimate variation of wheat grain protein content ( Rodrigues et al, 2018 ; Sharabiani et al, 2019 ), and monitor crop height variation during the season ( Ziliani et al, 2018 ).…”
