Filipova I. Agrotechnical measures of growing of the Sіlybum marіanum in the conditions of irrigation in the South Ukraine

Object of researches - Development of agrotechnical measures of growing of the Sіlybum marіanum in the conditions of irrigation on the south of Ukraine. The purpose of researches is development of agrotechnical measures: basic till of soil, width of spaces between rows, terms of sowing and background of mineral feed, at growing of the Sіlybum marіanum in the conditions of irrigation. Methods of researches - the field, laboratory, statistical; computation-comparative, economic, mathematical. Results of researches - For a theory: First for the terms of irrigation of south of Ukraine the water-physical indexes of soil and efficiency of the use of moisture and nutritives by the plants of the Sіlybum marіanum. Definite efficiency of action and co-operation of factors in the conditions of irrigation - basic till of soil, width of spaces between rows, terms of sowing, background of mineral feed and got mathematical models of harvest of seeds of the explored culture. For practice: On results the research are improved and offered to production the elements of technology of growing of the Sіlybum marіanum, which can be applied on the irrigated earths of South Steppe of Ukraine. The sphere of the use is the agricultural enterprises of south of Ukraine.
