Elements of biologization to ensure high energy and economic efficiency of sugar beet growing under the conditions of the Podillia

Abstract

Purpose. To study the ways of improving energy and economic efficiency of sugar beet cultivation based on the biological system of fertilizer grain-beet crop rotations under the conditions of sufficient moisture, the right-Bank forest-Steppe.
 Methods. Laboratory and field, statistical.
 Results. The results of studies on ways of improving energy and economic efficiency of sugar beet cultivation based on the biological system of fertilizers in grain-beet crop rotations under the conditions of sufficient moisture in the Right-Bank Forest-Steppe are presented, which included technology for sustainable cultivation of sugar beet under the conditions of an acute shortage of organic fertilizers. The technology includes the following elements of biologization: straw, green manure biomass was used as an alternative organic fertilizer directly under sowing of pre-crop. The positive results of increasing energy and economic efficiency of sugar beet is shown.
 Conclusions. In the acute shortage of organic fertilizers, it is required to use mineral fertilizers and basic elements of biologization, such as green manure, crop residues, and perennial grasses and legumes as pre-crops. This will contribute to the increase in the value of the gross output of feedstock, energy-economic viability and sustainability of agricultural systems in agronomic sense.
