During 2020-2021, a bifactorial experiment was set up on the ARDS Caracal cernozome to study the influence of biostimulator seed treatment (Ympact and Kerafol applied in different doses) on different levels of fertilization. The seed used in the first testing year-2021 and that obtained in 2022 was tested in terms of germination at different temperatures (1°C, 5°C, 10°C, 15°C and 20°C) as well as in terms of the number of days required for germination depending on the factors presented above. The Glosa wheat seed germinated at all temperatures, distinctly and very significantly more than at 1°C. However, there were no differences between the other temperatures, each taken as a control. The number of days required for germination is very significantly reduced from one temperature to another. At 1°C, wheat requires 33 days to germinate, while at 20°C, only 4 days. For the NPK fertilized variant in autumn + ammonium nitrate and foliar in spring, germination of the seed obtained is very little different between temperatures of 5, 10, 15 and 20°C and between the biostimulator treatment variants.
