Foliar microbiological fertilizer Algafix is represented by a mixture of living green algae speciesScenedesmus obtisausculus who are able to assimilate different hormones and antioxidants that aretransmitted through the leaves of the plant, stimulating growth and resistance to biotic and abiotic stress,and having an important influence for increased production. This paper presents an experience ofestablishing optimal Algafix dosage of winter rape and spring barley, with four graduations or doses of 1.5l/ha, 2 l/ha, 2.5 l/ha and 3 l/ha, which were compared with the control - untreated variant. We watched bothmorphological and physiological differences on the characteristics of plants in the experimental variants,and production quality indexes obtained, and the correlations established between doses of biofertilizers andmeasured parameters. In the same time, we studied how the doses of biofertilizers influence the water andmineral elements root absorption by plants grown in the two species, as well as economic efficiencycalculation. Compared with untreated control, all variants have obtained positive differences, mostproduction being registered variant V4 (dose of 2.5 l/ha), both in winter rape and spring barley cultures.
