The study was conducted in order to study the monitoring of the development of winter wheat plants on leached chernozem using non–invasive and traditional methods for determining the nitrogen content of soil - plants. Field studies were conducted from 2022 to 2024 on the land use of an agricultural experimental station within the framework of the state assignment for the provision of public services (performance of works) dated April 25, 2924 No. 082-03-2024-220/3 on the topic "Monitoring the development of crops using invasive and remote research methods and taking operational measures to adjust nutrition and phytosanitary conditions (Stage I)". The scheme of the field experiment involved the study of the following options: control, Background N13P60, Background +N35, Background + N51, Background + N70, Background + N87. The humus content in the 0...20 cm soil layer of the experimental site was 5.4% (according to Tyurin), mobile phosphorus and potassium (according to Machigin) - 25 and 270 mg / kg, respectively, N-NO3 – 30 mg/ kg, pH of the soil solution – 6.5 units. As a result of the research, it was revealed that nitrogen top dressing significantly increased the yield of winter wheat, and the difference in the average data relative to the control was 0.53 and 1.53 t/ha. The highest productivity of winter wheat relative to all variants of the experiment was provided by the option with the introduction of Background + N70 – 5.27 t/ha, which is higher than other variants of the experiment.
