The ways to increase the stability of plants of winter barley to harmful organisms when growing in the steppe zone of the Crimean peninsula

Abstract

The article presents results of research conducted in 20112014 in the steppe zone of the Crimean peninsula on the nonirrigated lands of the Institute of Agriculture of the Crimea. The aim of the research was to optimize the sowing terms barley of different biotypes in the conditions of the steppe zone of Crimea, to study the characteristics of the formation of barley agrobiocenosis in the system of technological methods of its cultivation and to develop on this basis the basic elements of agricultural technology adapted to modern conditions, which provides the most complete disclosure of the potential of productivity and sustainability to unfavorable development conditions, as well as an increase in resistance to pests of winter barley and two-handles in conditions of Crimean steppe. The terms of winter barley sowing have been improved due to changes in weather and climatic conditions. For the first time, the processes of growth and development of winter barley and two-handle barley when it was grown under conditions of the steppe part of the Crimea were studied. The practical significance of the obtained results is that for the conditions of the steppe zone of Crimea agricultural enterprises are recommended optimal terms for sowing winter barley and two-handles, which allows minimizing the negative impact of environmental conditions and ensuring active growth, increase and productivity of plants, as well as obtaining high-quality grain without additional costs of cultivation.
