The article describes the results of a three-year field experiment studying the effects of sowing periods on the crop structure, biometric indicators and productivity of white lupine varieties Degas and Gamma. The experiment was conducted in 2015-2017 on the leached chernozem of the experimental field of Kurgan State Agricultural Academy in the forest-steppe zone of Kurgan Region. The first sowing period corresponded to the physical soil maturity (the third decade of April - the first decade of May), the subsequent sowing periods were 6-8 days after the first one. Only in 2015, the full ripeness phase was not achieved (the third sowing period). The optimal sowing period was the first one: the yield of lupine grain varied from 2.5 to 14.9 t/ha.
