EFFECT OF MIXING BIO-ORGANIC MIXTURES WITH PLANTING MEDIUM ON THE GROWTH AND MEDICINALLY ACTIVE SUBSTANCE OF ROSEMARY PLANTS.

The research was conducted in one of the private nurseries to find out the effect of organic and biological mixtures on the growth and medically active substance of rosemary plants, as two factors (compost and biohealth) were used in the experiment, and each factor had four levels, the first factor being compost (30, 20, 10% of the weight of the anvil), and the second factor Biohealth (15,10,5) g.l^-1 in addition to the control treatment. The experiment was designed according to a Completely randomized design (CRD) and for three replicates. Each replicate contained three plastic pots and one plant for each pot. The L.S.D test was adopted to determine the level of significance among the experimental treatments. The results showed that the interaction between compost and Biohealth treatment was superior to all treatments if the treatment gave 30% compost and Biohealth 10 g.l^-1, the highest significant increase in the characteristics of the leaves content of nitrogen, potassium, phosphorous and the medically active substance caffeic acid was 0.028, 0.523, 1.496, 0.927, 2.158 respectively, while the treatment of Compost 30% and Biohealth 15 g.l^-1 gave the highest significant increase in the leaf content of the active substance rosmarinic acid.
