It was shown that pre-sowing seeds treatment of hulless oat with Microhumin preparation can reduce the dose of nitrogen fertilizer on 20 kg/ha by reactant. The highest yield increase – 0.65–0.77 t/ha was received in the variants with N20P60K60 and N40P60K60 background. Additional yield in variants with inoculation and under N60P60K60 dose of fertilizer was 0.5 t/ha. It was established that yield increase was obtained mainly due to the higher grain mass and index of productive tillering.
