The purpose of the experiment was to find alternative ways to replace traditional mineral fertilizers with less expensive biofertilizers. Simultaneously with the introduction of mineral fertilizers, we introduce at least twice as many slags, which have a long decomposition period and thereby pollute the soil and reduce natural fertility. The experiment conducted for 5 years gives full reason that new types of biofertilizers can be used in full to obtain a given yield threshold for varieties of hard spring and winter wheat. With lower costs for their purchase, they are able to bring the yield to 3.05 t/ ha (Don Elegia variety) and winter durum wheat to 3.84 t / ha (Aksinit variety) with the use of Gumi 20 biofertilizer. Based on the analysis of the experimental data obtained, conclusions were formulated about the mechanism of obtaining the specified yield levels of durum wheat varieties belonging to the spring and winter type
Key words: Spring durum wheat, winter durum wheat, biofertilizers, Gumi 20, Benefit+, grade Urasnokutka 13, grade Donskoy elegia, grade Aksinit, grade Agate Donskoy
