Gurev, G.P. | Vasilchikov, A.G.
The article presents the results of field experiments of 2017-2018 on the study of the influence of strains of nodule bacteria 653, 26-34, 700, as well as the synthetic growth regulator Melafen on the symbiotic indicators of nitrogen fixation (the number and weight of nodules) and the yield of beans. Positive effect of the above preparations, including Melafen on the formation of symbiotic apparatus and the harvest of beans, has been established. At the same time, the increase in grain yield, depending on the strain of root nodule bacteria, was from 9 to 55%, and from the use of Melafen, from 18 to 21%. It is noted that the synthetic growth regulator Melafen also stimulated the formation of nodules on the roots of beans, although it is noticeably less so in contrast to preparations of nodule bacteria. Also, the best strain under the code number 26-34, deposited in the collection of the ARRIAM strains in 2000, isolated in the laboratory of microbiology VNIIZBK under number 8 was selected
