Research was carried out during the experimental cycle 2004-2006 at Varias, on a typical chernozem. We studied four bacterial strains (NT4, NT5, NT16, and NT17). Results pointed out the negative impact of applying nitrogen fertilizers on the number of nodosities and on their weight. Among bacterial strains tested on the agri-fundN0 and N30, to notice NT17. On the agri-fund fertilized with N60, the total number of nodosities was close to the number of nodosities in all the strains studied.
