Abstract:
Considering the benefits of intensive agriculture in our time and the
negative impact of chemical fertilizers and pesticides against the
environment, usage of plant growth-promoting rhizobacteria like
biofertilizers is one of the most promising biotechnologies used for
increasing the primary production, eliminating the need of chemical
fertilizers. In this context, the aim of our work was to study the effects of
some rhizobacterial strains isolated from moldavian plaine cambic -
chernozemic soils on the development of soybean (Glycine max L.) plants.
During the vegetation phases we measured some biometrical parameters
(plant height, number of foils, foliar area, and nodulation). Our results
suggest that rhizobacteria can stimulate the plant development probably
through improvement of nitrogen fixation and radicular nutrients exchanges.
