In spring 2016, an abnormally early development of crops is observed in the southern regions of Russia. This phenomenon covers a number of regions, including Krasnodar, Rostov and Stavropol. This paper analyzes the phenomenon using remote monitoring data. The analysis was performed using the Vega-Science system that in particular allows obtaining information on weekly average NDVI values for arable land, winter and spring crops in comparison with the "norm" obtained by averaging the corresponding values for the period since 2001. By the comparisons, we can assess the condition of agricultural crops. It is shown that in the southern regions of Russia the NDVI values of winter crops are higher than "normal" by more than 25%. For spring crops, such pattern is observed in the Krasnodar and Stavropol regions, as well as on the south of the Rostov region. This paper considers the time variation of NDVI, showing that this year the development of winter crops is almost a month ahead of the "norm". Spring crops also demonstrate much earlier development. A comparison with previous years leads to the conclusion that this year witnesses the most significant anomaly of agricultural crops early development in the southern regions of Russia since the beginning of this century.
