It was established that treatment of buckwheat seeds with soil saprotroph mould Chaetomium cochliodes 3250 contributes to increase the number of N2-fixing bacteria in cropsroot zone. Thus, the number of Azospirillum and Azotobacter cell was getting more in rhizosphere soil. The number of all studied ecological-trophic bacteria groups was getting more on the root surface simultaneously with N2-fixation process intensification. Nitrogenase activity had grown in 1.3 times in rhizosphere soil and in 11.3 times on the root surface.The mold usage seemed to be positive to rise up the buckwheat harvest by 12.6%.
