The development of winter crops in southern regions of Russia during spring 2017 is similar to abnormally early developments observed in 2016. The paper presents results of an analysis performed using VEGA-Science system (http://sci-vega.ru/), which in particular provides weekly data on NDVI vegetation index values. The winter crops NDVI deviations from statistical norm (multi-annual NDVI for 2001–2016) estimated at the level of administrative regions provide information on the status of agricultural crops. The analysis shows that in Rostov and Volgograd Regions the 2017 winter crops demonstrate advanced development in comparison to 2016. The winter crops in Krasnodar and Stavropol Regions are growing slower compared to 2016 but they have more advanced status in comparison to the multi-annual mean scenario. The paper also demonstrates that at the beginning of April, the 2017 winter crops sprouting area exceeded corresponding data of 2016, in particular, in Kursk, Belgorod, Voronezh and Rostov Regions. Proceeding from these observations, we may expect the winter crops yield in these regions similar to the record yield of 2016. The analysis also shows, that in the southern regions of European Russia, the precipitation accumulated since the beginning of 2017 falls behind the value reached in 2016. However, in the second half of April this gap has reduced diminishing the risk of spring crops underdevelopment due to a lack of moisture in May 2017.
