Sowing time of winter crops in Belarus and recommendation for optimization in conditions of modern climate change

Assessment of agroclimate conditions the autumn period on territory Belarus under modern climate change with distribution cumulative temperatures during for 2000–2020 is presented. The results analysis estimates moisture indicators (precipitation amounts, Selyaninov’s hydrothermal coefficient, and productive reserves in arable soil layer 0–20 cm) are provided. Based literary sources, recent research by Belarusian scientists, data from observation points state hydrometeorological network phases development winter crops (wheat, triticale, rye) autumn, studies tillering depending sowing time weather period, an was carried out criteria were clarified to calculate optimal Belarus. grain has been calculated administrative regions observations, taking into account predicted air temperature September. Recommendations given calculating no as well possible consideration types field location.
