Study was conducted in the Horticulture department, Faculty of Agriculture and Forestry, Mosul University for the
period 15 September 2019 until 1 July 2020 to study the extent of the impact different types of Bio-stimulants powders (Garlic,

of control treatment. The experiment was conducted in randomized complete blocks designing RCBD with three replications
and 5 bulbs for one replicate. The treatment of yeast at a 12 g.plant-1 achieved the highest values of vegetative and flowering,
as for the yield of the volatile oil, the treatment of yeast at 12 g.plant-1 also achieved the best results, which amounted to 3.7%
for the percentage of oil and 40.25 g.kg-1 for the amount of oil and the best specific weight of the oil was 0.825, while the
density of the oil is 0.800.
