Optimal nutritional area for garlic seed plants

Abstract

Relevance. A large number of forms and varieties of garlic created in the selection process allowed this culture to spread almost all over the world: in temperate regions, in subtropics and even in tropical regions. Currently, the world's acreage of garlic is 1.438 million hectares, the average yield is 16.9 tons per hectare, the gross yield is 24.255 million tons. The largest producers of garlic are China, India, South Korea and Egypt. The highest yield was recorded in Uzbekistan, Egypt, China, Tadjikistan. In Uzbekistan, it is grown everywhere, mainly on household plots and small areas in farms. In the republic, varieties of garlic are South-violet (1972) and May VIR (1978). Material and methods. Since 2004, the Surkhandarya Scientific Experimental Station of the Vegetable Melon Crops and Potato Research Institute has been conducting selection work to create new varieties of garlic. As a result of the research, the Chidamli variety was introduced and, since 2016, introduced into the State Register. All zoned varieties belong to the group of autumn-sprouting varieties. The purpose of this research is to determine the optimal nutritional area for seed plants of garlic in elite seed production. The object of research was the garlic variety Chidamli. Results. During organization of elite seed рroduction, planting of clovers on pattern (40+15+15) x l0 sm, (40+10+10+10) x l0 sm was considered acceptable. Big and qualitatative bulbs and clovers were got bu this planting pattern. Yielding capacity was 24,4-26,2 t/ha, average weight of bulbs 63-66 g, clovers number 13,0 pcs., average weight of clovers 4,5-4,7 g.
