STUDIES REGARDING EFFICIENCY OF BIOLOGICAL FERTILIZATION WITH ALGAFIX ON WINTER RAPE AND SPRING BARLEY PRODUCTION
2015
Foliar microbiological fertilizer Algafix is represented by a mixture of living green algae species Scenedesmus obtisausculus who are able to assimilate different hormones and antioxidants that are transmitted 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 of establishing optimal Algafix dosage of winter rape and spring barley, with four graduations or doses of 1.5 l/ha, 2 l/ha, 2.5 l/ha and 3 l/ha, which were compared with the control - untreated variant. We watched both morphological 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 and measured parameters. In the same time, we studied how the doses of biofertilizers influence the water and mineral elements root absorption by plants grown in the two species, as well as economic efficiency calculation. Compared with untreated control, all variants have obtained positive differences, most production being registered variant V4 (dose of 2.5 l/ha), both in winter rape and spring barley cultures.
