GROBIOLOGICAL STUDY OF THE CULTURE OF CABBAGE IN THE CONDITIONS OF ASTRAKHAN REGION
The article presents data on the results of the variety study of white cabbage in the Astrakhan region, taking into account the climatic characteristics of the region. Soil and climatic conditions of the Astrakhan region are extreme for crop production, so the selection of the optimal assortment of white cabbage, maximally adapted to specific environmental conditions, is an important condition for reducing the negative effects of stress factors. In the course of research work the following methods were used: "Method of field experience» B. A. Dospekhov, «Experimental work in the field G. F. Nikitenko, «method of field experience» S. S. Litvinov. The article also provides data on the coefficient of water consumption of cabbage, phenological observations and biometric measurements. The influence of varietal characteristics on the yield and structure of the crop was determined. Material for the study was provided by the Federal state budget scientific institution «Federal scientific center for vegetable» (Federal state budgetary institution "FICO"). The most promising varieties of cabbage are identified during cultivation on drip irrigation. Most efficiently used the water of two mid-season varieties - Fame and Glory 1305 231 when the consumption ratio of 43,7 61,3 m3/kg, respectively. These varieties have shown productivity: Glory 1305 - 105 t/ha and the Glory of 231 - 81 t/ha. Planned area of research aimed at improving the efficiency of production of cabbage in the specific soil-climatic zone. In the future, the study of the agrobiological potential of varieties of cabbage on a complex of economically valuable traits is aimed at the allocation of a new source material for breeding purposes.
