Features of tomato development during inoculation by cyano-bacterial communities

The paper investigates the phytostimulating activity of cyano-bacterial communities on tomatoes (Solanum) in a laboratory experiment. The greatest germination, in comparison with bacteria of Bacillus megaterium, the EPIN – extra stimulator and control, was found in the experiment variant with treatment by the cyano-bacterial community No. 21 with a concentration of 0.05 g/ml – 70.0% on the 10th and 90.0% on the 20th day of exposure. The community was dominated by nitrogen-fixing cyanobacteria of the genus Nostoc. The maximum values for plant height and leaf count were in variants with inoculation by cyano-bacterial communities at a concentration of 0.05 g / ml. The most active phytostimulation properties have community No. 21 and No. 11
