MICROBIOCENOSIS OF RHIZOSPHERIC SOIL AND PRODUCTIVITY OF WINTER WHEAT UNDER THE USE OF AGROBACTERIUM RADIOBACTER 204, ACTIVATED WITH NANOCARBOXYLATES OF METALS
Journal Title: Сільськогосподарська мікробіологія - Year 2017, Vol 26, Issue
Abstract
The effectiveness of pre-sowing inoculation of winter wheat seeds with Agrobacterium radiobacter 204, pre-activated with nanocarboxylates of metals, and the preparation Avatar (a complex of trace elements - metal nanocarboxylates), applied in combination and separately, was studied. The combined application of bacterization and a complex of trace elements positively affects the microbiocenosis of the rhizospheric soil of winter wheat: an increase in the number of ammonifiers (from 43.8% to 77.1%), nitrogen-fixing bacteria (from 2.7 to 3.5 times) was noted, while the number of micromycetes reduced. Pre-sowing bacterization and application of nanocarboxylates of metals contributes to the increase of the potential nitrogen-fixing activity of rhizosphere soil and increase of wheat yield by 24.4% compared with the control variant.
