The influence of microbiological fertilisers on the productivity and quality of winter wheat

Abstract

The study was aimed at assessing the yield and quality of winter wheat grains inoculated with Beijerinckia fluminensis (Azotovit) and Paenibacillus mucilaginosus (Phosphatovit) in a three-year experiment on leached Chernozem in the forest-steppe zone of the Middle Volga region. The seeds of the plants were treated before sowing with microbiological fertilisers, both individually and together at a dose of 2 L/t. Bacteria Beijerinckia fluminensis and Paenibacillus mucilaginosus contained in fertilisers increased the resistance of plants to adverse conditions: seedling completeness increased by 5.4%, winter hardiness by 17.4%, and harvestability by 15.0%. The use of fertilisers led to an increase in the productivity of winter wheat grain to 32.4%. The technological parameters characterising the baking properties were improved: the content of crude gluten in the grain of winter wheat has increased to 29.1% at 75 GDI (gluten deformation index) units (I group (good) of gluten quality).
