Abstract:
Integrated farming systems have microbiological bases in soil, microorganisms having the ability to govern nutrient
flows to and from plants. Improvement of production is based on calibration and balancing of circuits driven by
rhizosphere microorganisms. Bioproducts have the role of supplementing microbial groups with a role in promoting
plant growth. The purpose of the paper is to determine the global reaction of two wheat varieties to the application of
bioproducts based on active microorganisms. The over- and underground growth of plants and the synthetic indices
resulted from them were followed. Development parameters are significantly influenced by the application of
bioproducts. In general, autumn wheat variety has a higher developmental balance than the spring one. For autumn
wheat the presence of the microbial consortium caused the plant to transfer significant amounts of resources to the stem.
The biological bases of spring wheat give it an oversize increase much higher than the winter wheat. A possible
explanation for the growth and gradual development of plants is the provision of organic substances in a constant flow
from both sides. For microorganisms, this situation has led to their proliferation irrespective of the presence of other
organisms, and for the plant has ensured normal growth and development. Also in the case of spring wheat, the
correlation between the stem and the root is lower than in the autumn one. The autumn variety has a clustered
development, with an evolution in favor of the stem in the early stages of vegetation, and then leads to a stronger
development of the root.
