Control the productivity of flax by treating seeds with microelements and nanopreparation

Abstract

The purpose of the research was to compare the effectiveness of nanopreparation Nutrivant Plus and trace elements on the growth, development and yield of flax. The experiment was conducted in 2017-2018 on the field of the Smolensk State Agricultural Academy. The object of the study was the flax variety S-108, zoned in the Smolensk region and bred in the Smolensk Research Institute of Agricultural Sciences (former Smolensk State Agricultural Stantion). According to the results of the experiment, it was found that trace elements and nanopreparation increased the germination of flax seeds to 93.6 %. The density of standing plants and their number before harvesting in the variants with the use of trace elements was higher than when using nanopreparation. Treatment of flax seeds with solutions of trace elements to a greater extent contributed to an increase in the yield of flax products. The largest increase in flax straw was obtained from wetting the seed material with iron and zinc sulfate – 3.2 – 4.2 t/ha (53-70 %); for flax fiber – 0.8 – 1.1 t/ha (89 – 122 %). The highest yield for seeds was obtained from treatment with nanopreparation, the increase relative to the control was 0.2 t/ha or 67 %. To achieve high profit and profitability in the cultivation of flax, it is advisable to combine seed treatment before sowing (wetting) with 0.05 % water-dispersed suspension nanopreparation of Co and Fe.
