The pre-sowing spring wheat seeds treatment effectiveness by biopreparation LPB

Pre-sowing treatment of seeds of grain crops is recognized as one of the most effective ways to increase yield. Seed treatment carried out by chemical, biological and physical methods. The FGBNU VNIIMZ has developed a multifunctional liquid-phase biopreparation - LPB, whose distinguishing features are agronomically beneficial microflora, as well as physiologically active substances and nutrients for plants. The effect of LPB on growth and development is associated with an increase in metabolic processes, in particular with the transformation of hardly accessible organic compounds of the soil. The aim of the work was to study the effect of the pre-sowing treatment of seeds of spring wheat Irgina cultivar with the biopreparation LPB on the yield and individual indicators of grain quality. The results of laboratory and field experiments conducted in 2017-2018 are given. In a laboratory experiment, seven different concentrations of LPB were tested. The best biometric indicators of plants were noted in the variants using 1% and 2% concentrations, which were used during the field experiment...
