Abstract: The article presents the results of experiments on the use of growth stimulants for pre-sowing seed treatment in primary seed production of spring durum wheat of the Triada variety in 2022-2024. Two-component combinations of drugs were used as stimulants: Kornevin, Gumi-20, succinic acid, ethamone and chlorella suspension. Kornevin + succinic acid and Kornevin + ethamone increased germination energy by 2.5-3.0%, and laboratory germination by 4.0% and 3.0%, respectively. The yield of spring durum wheat in the succinic acid + chlorella suspension and Kornevin + Gumi-20 variants increased by 0.36 and 0.46 t/ha, including coarse fractions by 0.1 and 0.14 t/ha compared with the control. The yield in the Kornevin + Gumi-20 variant increased due to an 8.8% increase in the number of productive stems per 1 m2, a 6.6% increase in ear water content and a 6.3% increase in grain weight per ear, which resulted in a 15.1% increase in yield. The maximum value of the seed cenosis capacity of 7034 units/m2 and a reproduction coefficient of 1:39.1 was obtained using a root growth stimulator (1 g/l of water) + Gumi-20 (2 ml/l of water). A high content of protein and crude gluten at the class 2 level for durum wheat grain was established during pre-sowing treatment with root growth stimulators (1 g/l of water) + chlorella suspension (diluted with water 1:4) and succinic acid (1 g/l of water) + chlorella suspension (diluted with water 1:4). These growth stimulators are recommended for the pre-sowing treatment of spring durum wheat seeds of the Triada variety in primary seed nurseries.
