The conducted studies were supposed to establish the relationship between the influence of calculated mineral nutrition and the treatment of durum wheat seeds before sowing on yield indicators and quality. Currently, the cost of mineral fertilizers has increased significantly, in addition, together with their introduction, we automatically introduce slags into the fertile layer, which are the accompanying elements of fertilizers. In this regard, the alternative presented by us in the form of seed treatment with biofertilizers is very relevant. The conducted long-term surveys give full reason that new types of biofertilizers can be used to obtain a given level of yield of varieties of hard spring and winter wheat, as well as their joint use with the estimated amount of mineral nutrition. Based on the conducted experiment, it can be stated that the use of Gumi 20+N221P87K135 on a variety of winter durum wheat can be obtained on the chernozem of the southern Volgograd region 6.62 t/ ha, while a yield of 3.03 t/ ha was obtained on the control variant of this variety. The yield of spring durum wheat varieties on the Gumi 20+N221P87K135 variant was slightly lower and it amounted to 13 – 2.50 t/ha for the Krasnokutka variety, and 5.32 t/ha for the Don Elegia variety
