Melnichenko T. Productivity of turnip celery varieties and improvement of seedling technology under the conditions of the Right-Bank Forest-Steppe of Ukraine

Object: patterns of high productivity and quality of commodity production coriander sowing depending on the methods of growing technology. Purpose: To develop effective elements of the technology of growing coriander sowing in forest-steppe of Ukraine. Novelty: first recommended varieties of coriander sowing to grow in open ground by applying the optimal time and method of planting and layout. Determined the most effective growth regulators for pre-treatment of seeds. The economic analysis and calculated biology assessment of the proposed elements of the technology of growing coriander sowing. Results: in the forest-steppe of Ukraine the high yielding capacity of verdures given by such varieties as Americano and Yantar- 3.3 t/ha by increasing the mass of plants to 12,0 and 11,7 g. The largest mass of seeds from one plant and yield from 1 hectare obtained in a variety of Americano - 2,5 g/plant. More cost-effective is growing of coriander sowing method for circuit placement 15х8 cm and density of plant 830 thousand pcs./ha. For the first time it was proved that pre-treatment of seeds of coriander with plant growth regulators and Lihnohumat and Emistim C promotes faster germination of seeds, increases germination, enhances growth and helps to increase productivity of output sowing coriander of Yantar variety at 0,56-0,64 t/ha and Nectar variety of 0,48-0,57 t/ha and improved indicators of chemical composition.
