Study of the effect of the application of an organic microelement complex on the yield and quality of field crops in the conditions of the Saratov Left Bank

Abstract

The article presents the materials of studies of effect of foliar application of organomineral fertilizers on the productivity and quality of agricultural crops grain in the conditions of dark chestnut soils of the Saratov Left Bank. It is shown that the application of an organic microelement complex (OMEK “Universal”) contributes to an increase in yield at the level of 0.28 t/ha in winter wheat. of 0.07 t/ha in chickpeas and sunflower and of 0.23 t/ha in corn. Analysis of the product quality showed that after foliar fertilization with an organic microelement complex (OMEK “Universal”). these values were higher compared to the control and after application of Bionex-Kemi. When calculating the economic efficiency. the highest indicators of net income were after foliar application with fertilizer with an organic microelement complex (OMEK “Universal”).
