Efficiency of pre-sowing seed treatment of spring barley by nanostructured water-phosphorite suspension

This article presents the results of a study on the use of phosphorite rock of the usual grinding of the Syundyukovskoye deposit in the Republic of Tatarstan and nanostructured water-phosphorite suspension as a means for pre-sowing seed treatment of the main feed crop of the republic - spring barley (Hordeum vulgare) when grown on heavy loamy leached chernozem based on an experimental field in the Buinsky municipal district of Tatarstan. The effect of phosphorite rock and nanostructured water-phosphorite suspension on the yield and quality indicators of spring barley cultivar Rakhat was studied. In field experiments, the effectiveness of treating barley seeds with a nanostructured water-phosphorite suspension was revealed. In field experiments, the effectiveness of treating barley seeds with a nanostructured water-phosphorite suspension at a dose of 1.25 kg per ton of seed was revealed. The acceleration of the passage of the phases of plant development (seedlings, tillering, exit to the tube) by 2-5 days, an increase in productivity by 2.0 15.0 centner per hectare and an improvement in grain quality in terms of protein content of up to 10.8 % in comparison with other experience options were established.
