Sowing qualities of spring barley seeds when using biostimulants

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%.
