Abnormally low air temperatures have been observed in April-June 2017 in many regions of the European part of Russia. This led to delays in the development of vegetation, including agricultural crops. The weather anomaly impacted most significantly the sowing time and development of spring crops. We show that in many regions of European Russia, spring crops follow an anomalous scenario of growing which strongly differs from their multi-year average development path. Maps of spring crops’ NDVI deviations from multi-year means aggregated within administrative regions are presented. Also, detailed analysis of NDVI seasonal dynamics for some regions is performed. It has been demonstrated that at the beginning of May and in the first half of June 2017, spring crops’ NDVI values were significantly behind multi-year mean trajectories, but by the end of June, they mainly reached or, in some cases, even exceeded those levels. At the same time, in the regions of observation during the analyzed period the accumulated air temperature was significantly behind its trajectory of 2016. Thus in 2017, we certainly observe an abnormal development of spring crops in European Russia.
