The use of organic fertilizers in the ecological production of sugar, fodder and table beets increases significantly the volumes of organic raw material for production of forages and food. The influence of variants of treatment with the organic fertilizers Free N 100, Raim Zolfo, Heliosulfure, and the biodynamic preparations 500 and Fladen, on the productivity and dry matter content of the sugar beet variety Diex, fodder beet variety Sasha and Radost table beet variety has been tested on the Experimental ecology field (carbonate black earth) of AI-Shumen during the period 2019-2020. The test was conducted using the long plots method in 4 repetitions with 8.2 sq. meters area of the experimental plot, in crop rotation of wheat-beet-sorghum, without any use of conventional pesticides and fertilizers. The productivities of the treated with biological preparations variants exceed that of the control in the more favorable for the development of the crops 2019, as well as in the extremely dry for the vegetation 2020.
