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,
Yeast, Tea, Bananas peel) on the growth and floral characteristics of Hyacinthus orientalis L. Pink pereal variety. The
concentrations 6, 12 g of Garlic, Yeast, Tea, Bananas peel has been used which was added to the soil every month in addition
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.
