The average mass of shallot onion bulbs was: variety Uralsky 40 – 51,3 g, Krepysh – 48,1 g, Debut – 49,7 g, Ural violet – 34,4 g, Monastyrsky – 76,9 g. The maximum average weight of the bulb was obtained in the variety Monastyrsky, a significant excess of the studied varieties was 50-124%. The minimum average weight of the Ural violet variety is significantly less than other varieties. According to the average weight of the bulbs of the Uralsky 40, Krepysh and Debut varieties, there were no significant differences. In terms of yield, the varieties Monastyrsky (2,32 kg/m2) and Uralsky 40 (1,86 kg/m2) significantly exceeded the varieties Krepysh, Debyut and Ural violet by 52-123%. The difference between the last three varieties is not significant. The high safety of bulbs was noted in varieties Ural violet and Ural 40 – 96.2 and 86,4%. The average safety of bulbs in varieties Debut and Krepysh was 76.2 and 60,2%. The bulbs of the Monastyrsky variety were the worst preserved, only 42,8% of healthy bulbs. Root treatment with a solution of grade A of the agrochemical Tyumensky at a dose of 2 l / m2 had a positive effect on the productivity of shallots, variety Uralsky 40, the size of the bulbs increased, and the yield increased by 28-36%.
