Rudik O. Agro-Ecological Substantiation and Development of Basic Elements of Cultivation Technologies of Dual Purpose Oil-Bearing Flax under Conditions of the South of Ukraine

Object of research - The process of growing flax oil double use depending on agroecological features and technological measures in the southern Ukraine. The purpose of the research is agro-ecological substantiation and development of elements of adaptive technology of growing flax oil on irrigated and irrigated lands for efficient dual use of production according to the existing possibilities for technical processing of stems. Research methods - general scientific, special methods: field; laboratory-field; biochemical analysis; comparative settlement; physical-statistical modeling. Research Results - For Theory: For the first time, an agro-technological set of conditions has been created to enable the creation of a dual-use flax oil morphotype. A detailed technological assessment of flax straw on the basis of histological and physicochemical analysis is given. In the conditions of the South of Ukraine the complex influence of moisture supply, mineral nutrition backgrounds, row widths, seeding rates on the processes of formation of biological mass of culture, dynamics of quantitative and qualitative indicators of seeds and stems were studied. For Practice: According to the research, technology elements have been substantiated that provide high yields and yields suitable for the technical processing of straw. Of the available varieties are offered the most suitable for the production of seeds and simultaneous removal of the bark of straw. Experimental studies have found that the intensification measures that provide increased seed yield at the same time cause an increase in yield and straw quality. The necessity of a differentiated approach to the choice of technological schemes of straw processing and use in accordance with the soil-climatic conditions and technical support of farms with the means of harvesting is grounded. Scope - agricultural enterprises of southern Ukraine.
