Abstract: The losses of agricultural production in Bulgaria, as a result of climatic anomalies and unfavorable weather conditions during the years since the beginning of the 21st century, are significant and are growing continuously. The dates of the last spring and first autumn frosts limit the potential growing season. Damage from late spring frosts is a major limiting factor for the production of agricultural products. In the last 40 years, studies on the regime and risk of occurrence of late spring and early autumn frosts with data on a sufficient number of observation points have not been done. The aim of the study is to assess the risk of late spring frosts in the agricultural lands of Bulgaria. The phenomenon of frost is observed in the NIMH meteorological network. Agricultural crops are affected by frost during the potential growing season. We selected the cases of frost appearance after the permanent transition of air temperatures above 10°C for 50 stations from the territory of Bulgaria. The study period is 1991-2022. The results of this study will be useful in assessing the agroclimatic resources of a given region and planning agricultural production, especially for some spring crops and orchards.
