Abstract

In the conditions of global warming, in particular the growing aridity of the steppe zone of Ukraine, as well as the deficit of organic matter and declining nitrogen reserves in the soil, agricultural producers are faced with the task of finding effective cultivation of drought-resistant crops that are competitive in the market, have economic feasibility and unpretentiousness in cultivation. Producers of agricultural products have paid attention to the cultivation of non-traditional culture – amaranth, which is distinguished by its biological characteristics and agrotechnics action to increase soil fertility in climate change. It was found that the optimal sowing density for growing amaranth in arid conditions of the Southern Steppe of Ukraine is 150 thousand pieces/ha. Under such conditions, the highest yield of amaranth grain is formed: for the universal variety Kharkiv-1 – 3,06 t/ha, for the grain variety Lera – 3,34 t/ha. At a sowing density of 150 thousand pieces/ha, the highest values of 1000 grains were obtained: for the universal variety Kharkiv-1 – 0,665 g, for the grain variety Lera – 0,678 g. These options provided the highest mass fractions of moisture, which were 8,6 and 9,1%, respectively. It was found that in order to obtain quality products from harvesting to processing of amaranth grain, it is necessary to use a set of technological operations aimed at preventing crop losses and preserving its useful properties
