Mykolaiko V. Peculiarities of formation of yield and quality of seeds of chicory root, depending on agro-technological measures of Ukraine

In this dissertation the theoretical generalization and new solution of scientific problems are provided, which manifests itself in ensuring the high yield and seed germination of chicory root on the basis of studying of biological peculiarities of growth and development of plants and seed production, depending on weather conditions of vegetation period, dates and methods of planting, feeding area, directed regulation of the process of flowering and setting of seeds in irrigated and rainfed conditions, levels of fertilizer and methods of formation of generative organs. Theoretically substantiated and developed the basic elements of technology of cultivation of seed and a seedbed preparation of seed. It was experimentally proved that the quality of the seeds depends on its productivity; there is a strong correlation between these indicators. Direct average correlation was established between root yield and inulin content and between inulin content and dry matter content. On the basis of studies the conditions of storage of uterine root crops of chicory root was substantiated and the influence of genotype on chemical composition during storage. The close correlation between the seed yield of chicory root and its laboratory similarity was discovered as in rainfed conditions of cultivation, so with drip irrigation. The use of complex agronomic measures - drip irrigation, the optimal layout of the seed of chicory and their pinching provides a significant increase in the yield of seeds. It was found that the quality of seeds depends as on planting schemes of seed, using of mineral fertilizers and so the modes of drip irrigation. The economic efficiency of the developed agrotechnological activities was identified. Key words: drip irrigation, roots, pinching, scheme and planting term, survival rate, productivity, flower formation, tying of seeds, laboratory similarity, and storage of uterine seed.
