Hyssopus officinalis is not of the most important medicinal plants. It is used as a medicinal, spice essential oils plant and its flowers and leaves are used in food industry flavouring liquers and candies. As a medicinal plant, It is used as an antiasthema, chronic, coughs and bronchitis diseases.
The results of this project will help in the further improvement of production of hyssop seed yield for pharmaceutical, cosmetical and food industries. The main purpose of this project is the investigation about effect of nitrogen and phosphorus fertilization and also finding out the most suitable amount of them which could be used for hyssop cultivation in order to increase quantity of hyssop seed yield. The treatments consisted of all combinations of four levels of N & P. We have studied the effect of increasing (0, 20, 40, 60, kg/ha) N & P DOSAGE. The experimental plots were laid out in randomized complete blocks with four replicates in every treatment.
On the basis of examinations, it could be concluded that N fertilization had a very important role on the seed yield.
