The use of broadband vegetation indices to assess the weed infestation of crops

Remote monitoring of crops is limited by the absence of vegetation indices that responds contrastingly to specific technological techniques. The paper studies broadband vegetation indices and their responsiveness to weed infestation of crops and to the availability of nutrients. The EVI 2 and CVI vegetation indices significantly differed on different winter wheat nutrition systems, and the CI red edge index showed significant differences between herbicide-free and on herbicide technologies for different nutrition systems. The NDVI index did not have high reliability for any of the studied factors of agricultural technology. The obtained results demonstrate the potential of multispectral cameras for obtaining economically useful information with their correct joint interpretation.
Keywords: Vegetation indices, CIred edge, fertilizers, multispectral camera, UAV, winter wheat, weeds.
