The paper presents the results of remote assessing of the state of winter crops in the South, Caucasian, Central and Volga Federal Districts of Russia in spring 2023. A review of agrometeorological conditions on the above mentioned territories is given to assess the factors that influenced the state of winter crops. The meteorological conditions in autumn 2022 negatively affected the course of the sowing campaign in a number of regions: so, undersowing of winter crops was recorded in five regions of the Central Federal District based on remote sensing data in the end of 2022 compared to the end of 2021. In a number of regions of the Central and Volga Federal Districts, overwintering conditions had an adverse effect on the crops state: strong temperature fluctuations and insufficient snow cover led to a deterioration in the crops state up to their death. In general, the analysis of satellite data for the second half of April 2023 showed that a favorable situation with winter crops was observed in the Southern and North Caucasian Federal Districts, where crops developed close to or more intensively that the average multi-year norm, while in the southern regions of the Central and Volga Federal Districts winter crops developed worth than the average long-term norm and, in particular, fields with resowing of winter crops are recorded.
