Pysarenko P. The theoretical study and practical implementation of the use of different types of irrigation modes and methods of watering crops

The object of researches is the processes of forming of supplies of moisture in soil on sowing of basic agricultural cultures; dynamics of consumption of water and average daily evaporation; products processes of plants depending on the modes of irrigation, methods of watering and other factors of vital functions. Purpose of researches - scientifically theoretical ground of agrobiological bases of planning of the modes of irrigation and methods of setting of watering of basic agricultural cultures taking into account the changes of environmental, economic, technological, ecological and power conditions of conduct of the irrigated agriculture in South Steppe of Ukraine. The methods of researches are scientific methods, analytical, field, laboratory, statistical, computation and comparative-calculable. Results of researches - For a theory: First, for the modern terms of conduct of the irrigated agriculture in South Steppe of Ukraine conformity to the law of consumption of water for modern sorts and hybrids of alfalfa, wheat of winter, corn, soy is set, beet of saccharine at the natural and artificial moistening at different methods of watering and weather terms of years, the areas of the active use of moisture from soil are definite by the plants and dynamics of absorption of her during vegetation; statistical models are developed. For practice: Software for the operative planning of the modes of irrigation of agricultural cultures on the bases of design of average daily evaporation of different after biological signs cultures is developed. Complex estimation of the ekologo-meliorativ state of the irrigated arrays in the area of action of Ingulets and Frunze is conducted orositelnih systems and developed measures with the purpose of rise of productivity and improvement of their ecological state. The sphere of the use is the agricultural enterprises of south of Ukraine.
