Influence of microbiological preparations on the yield and sowing qualities of buckwheat seeds in the Orel region

Nowadays, a large amount of experimental material has been accumulated, which notes the positive effect of biologics on the yield and quality of various crops, including buckwheat. With the introduction of intensive technologies, it is important not only to increase yields, but also to improve the sowing qualities of seeds. Therefore, this aspect has been reflected in the research. The aim of the research was to establish the effect of microbiological preparations BioAzFK and Fitosporin-AS used in pre-sowing seed treatment on the yield and sowing qualities of buckwheat seeds in the conditions of the Orel region. The field experiment was conducted on the basis of the SEPC "Integration" of the Orel State Agrarian University named after N.V. Parakhin. The object of the study was the seed material of buckwheat of 2022 sowing of the variety Devyatka. As a result of the conducted studies, it was found that the combined use of biologics BioAzFK (3l/t)+ Fitosporin-AS (1.5 l/t) as a pre-sowing treatment of buckwheat seeds increased the germination energy of seeds by 8% to control, and laboratory germination by 3.2%. Taking into account the density of standing buckwheat plants in full shoots showed an advantage from the joint use of the two studied biological products. In this variant, the density of standing plants was 11.3% higher than in the control. The variants with separate use of biologics differed slightly from each other, however, against the background of control, they showed a significant difference of 4.4 and 6.9%, respectively. The largest increase in buckwheat grain yield to the control was on average in the BioAzFK (3l/t)+ Fitosporin-AS (1.5 l/t) variant: 18.9 c/ha, which was 17.3% higher than in the control. All the experimental variants significantly differed from the control, giving an increase in yield from 7.5 to 17.3%. A significant mass of 1000 grains (34.8 g) was obtained from the seeds of buckwheat plants of BioAzFK (3l/t)+ Fitosporin-AS (1.5 l/t).
