In the training and experimental farm of the Kuban State Agrarian University Krasnodarskoe from February 19 to July 6, 2020, an experiment was conducted on the comparative analysis of differentiated fertilizer application in on-line and off-line modes. The aim of the experiment was to compare the modes of differentiated application of nitrogen fertilizers (first and second top dressing) for winter wheat using task maps and GreenSeeker sensors. The calculation of economic efficiency showed that when using nitrogen scanners, fertilizers are saved on average 16 kg / ha, compared to the mode of creating task maps based on the NDVI index based on satellite data without losing grain yield and quality (gluten content increased by 2.3 %; protein content-0.6 %).
