THE EFFECTS OF THE ORGANIC TECHNOLOGY ELEMENTS OF GROWING ON SOYA PRODUCTIVITY UNDER CONDITIONS OF POLISSIA OF UKRAINE

Abstract.

The materials of the field studies on determining the effects of the organic technology elements on growth, growing and crop yield of an ultra- early soya sort Ustia as well as the accumulation of a biological nitrogen of the air on the light-grey soils of Polissia Ukraine have been given. The essence of the organic technology elements lies in growing ecologically safe produce without the application of both mineral fertilizers of synthetic origin and pesticides, in the renewal of soil fertility with the application of inoculants of biological origin as well as complex fertilizers on the chelating basis. It has been proved that on the light-grey soils of Polissia, seed inoculation by the inoculants Optimize 200 and by phosphorobacterin, as well as foliar fertilizing with complex fertilizers on the chelating basis in the period of seed upswelling enable to receive a soya crop yield at a rate of 3.25-3.33 t/ha. As many as 212 kg/g of biological nitrogen are accumulated in topsoil on account of fixation the nitrogen of the air by the bacteria, by means of byproduct covering (straw), leaves’ phyto-mass and root remains. It has been determined that soya growing on the mixture of perennial grasses with the application of the elements of biologization enables to receive biological yield within 3.54 t/ha, that exceeds average annual yield (2016-2018) by 0.29t/ha as compared to its growing on one field during three years (monoculture)
