Kapustina L. Substantiation of the items of the technology of garlic growing in Forest-Steppe zone of Ukraine

The results of 3-year research of the definite items of garlic growing technology are submitted. Trails were set in the Forest-Steppe zone of Ukraine. Different varieties of garlic (Promin, Starobilsky mistsevy, Marmurovy, Kozak, Dobrody, Hotynivsky, Shotynsky) were estimated by their economical and biological properties. It were determined yields of underground and air bulbs of above given varieties, number and weight of air bulbs from one plant, biochemical composition. It was determined the influence of the terms of winter garlic planting using cloves and air bulbs. The best time for planting of winter garlic cloves is first decade of October. The quiescence state, plants development and yields were taken into consideration at determining the best term of planting. At this term is was obtained the garlic yield 12,3-13,3 t/ha. Following varieties of garlic were estimated by their yield, bulb weight and biochemical composition: Ukrainian bily hulyaipilsky, Odesky 13, Zhytomyrsky, Vinnytsky. Two of them were recommended for State Committee, that is responsible for seed-trial and development of the List of varieties allowed to be grown in Ukraine. The best time for spring garlic growing appeared to be the early spring at the time of the first ability to go on the field. This time of planting allowed to get 4,3 t/ha of garlic bulbs.
