Using two rice genotypes as a test system (OP1505 and OP1509), the aim of this studywas to develop an agronomic workflow for Se biofortification through foliar fertilization (withsodium selenate and sodium selenite). During the biofortification process, the state of the culture(slope, surface drainage, water lines and normalized differences vegetation index—NDVI), using anUnmanned Aerial Vehicles synchronized by global positioning system (GPS) was further assessed.It was found that after sowing, the water-drainage pattern became profoundly altered, followingthe artificial pattern, created by grooves between plots. NDVI values, compared to the control, didnot show significant differences. These data were correlated with physiological monitoring duringbiofortification. Furthermore, it was found by eco-physiological data obtained through leaf gasexchanges, that the application of 300 g Se ha−1did not show any toxicity effects in the biofortifiedplants. In the context of innovation, it was concluded that the application of precision agriculturetechniques in conjunction with leaf-gas exchange measurements allow for an efficient monitoring ofthe experimental field conditions and the development of the rice cycle during the implementation ofthe biofortification workflow.
