Abstract
The results of the developed methods of increasing the sowing qualities of spring barley seeds, which will significantly increase the crop yield, are presented. As a result of the studies it was found that the application of biostimulants contributed to the increase of laboratory germination rate by 20.8−33.3 %. The most significant increase occurred when treated with Albit biostimulant - 96.2%. Sprout length increased in variants with soaking in solution of Epin-Extra (11.4 cm), Zircon (11.9) and Albit (11.6). The length of roots increased by 28-52%. There was an increase in the biomass of seedlings in all variants with treatment by 7.2-12.2%. Application of preparations significantly increased the number of roots by 30...36% compared with control. At the same time, the positive role of biostimulants Albit and Restart, Zh in increasing the height of seedlings by 20-27%.
