Common bean (Phaseolus vulgaris L.) is one of the most commonly grown legumes worldwide, whose production is often exposed to the negative effects of drought. The aim of this study was to determine the suitability of multispectral analysis, i.e. vegetation indices in the detection of drought stress in common bean. Two treatments were used in this experiment: 1. control solution and 2. solution with the addition of polyethylene glycol (PEG) which stimulates drought stress. 5 common bean landraces were used ('Biser', 'Puter', 'Tetovac', 'Trešnjevac', 'Zelenčec'), of which 5 plants were grown in each treatment. On the sixth day after application of the treatment, the plants were scanned with a multispectral 3D plant scanner. The intensity of reflection of electromagnetic radiation in the visible part of the spectrum (red, blue and green), near infrared (NIR) and far red (FR) were analysed. Based on these data, vegetation indices such as chlorophyll index, anthocyanin index and normalized differential vegetation index were calculated. Significant differences were found between drought treatment and control for all measured parameters except for the intensity of electromagnetic radiation reflection in the red part of the spectrum. The obtained results indicate the suitability of using multispectral analysis in the assessment of drought stress in beans.
