Effect of different biologics for presowing seed treatment for sowing indicators of winter soft wheat

The article presents the results of studies on the influence of organic-mineral fertilizers Alga 1000 and Gumiful Pro, growth regulator Program "Mak-simum," humic fertilizer Gumavit, growth stimulator Ruther for seed treatment on the fractional composition, weight of 1000 seeds and their level-ing in varieties of winter soft pine-nitsa Don 107 and Elanchik in field experi-ence on chernozem ordinary. The highest specific gravity of the studied varie-ties was a fraction with a seed thickness of 2.6-2.4 mm. The maximum leveling in the Don 107 variety was provided by the drug Gumiful Pro- 85.9%, in the Elanchik variety - an option with the Maximum program - 89.4%. On the basis of "mass of 1000 seeds" in the Don 107 variety, the maximum values were es-tablished on control, and in the Elanchik variety when using the drug Gumavit. In laboratory conditions, the effect of drugs on the inoculation properties and linear sizes of seedlings of the studied varieties was established. Both varieties showed the maximum laboratory germination of seeds in the version with Gumiful Pro – 99%.
