Evaluation of the Onezhskiy liquid humic preparation effect on the growth and productive indicators of barley (Hordeum vulgare)

The yield of grain and leguminous crops in the Vologda Region lags significantly behind that in the Leningrad Region, while a comparative analysis of the fertilizers used for cultivating agricultural crops in these regions has revealed significant differences relevant only to the application of organic fertilizers (the difference is 2.3 times). The purpose of the work is to study the effect of the Onezhskiy liquid humic preparation, which has been developed and produced in the Vologda Region, on the growth and productivity of the Sonet barley variety. The results of the small-plot field experiment in 2024 has showed significant efficiency of its use: during the heading phase, the assimilation surface of barley increases by 2.7 times, the chlorophyll content by 34-45%, and the final grain productivity by 13- 50%. It should be noted that the most effective method of applying this preparation has been a one-time soaking of barley seeds before sowing and phyllosphere spraying. The results allow us to confirm that the Onezhskiy liquid humic preparation has turned out to be more effective than the wellknown and widely used preparation «Gumat +7».
