FORMATION OF CARROT BIOLOGICAL PRODUCTIVITY INDICATORS UNDER THE INFLUENCE OF THE FERMENTED ORGANIC FERTILIZER AND THE MICROBIOLOGICAL PREPARATION

Abstract

The effect of the fermented organic fertilizer and the microbiological preparation on the yield capacity level of carrot and the quality of the obtained product was investigated. It was found that significant crop yield increases (on 26,0–38,4 %) when the fermented fertilizer is applied (11 t/ha) or in cases of its integrated usage (5,5 t/ha) together with the microbiological preparation, as well as soil treatment using the preparation with previously applied mineral fertilizers (N₃₀). When the fertilization systems under consideration are used, quality indicators of the root crop are significantly improved – there is an increase of carotene content and nitrate level does not exceed the maximum allowable concentrations.
