Abstract

A factor experiment was carried out in the horticultural facility unit of the Department of Horticulture and Gardening Engineering / College of Agriculture - Tikrit University for the period from February-June 2020 to study the effect of fertilization with Mycorrhizae and NPK on the growth of the root system and the active compounds of volatile oil in the leaves of the plant aromatic tea Pelargonium graveolens L. The experiment included two factor factors. The first is to add the biological fertilizer to the Mycorrhiza fungus at two levels without addition (comparison) and the addition at a concentration of 18 gm.pot-1 The second factor is spraying with chemical fertilizer NPK in three levels, the first without adding (comparison), the second is spraying the plant with 1 gm. Liter-1 and the third is spraying a plant with 2 gm . liter-1. Implemented according to the Randomized Complete Block Design (R.C.B.D). The results showed that the treatment exceeded the addition of Mycorrhizae as the percentage of dry matter to the root total, which amounted to 26.342%. While the NPK addiction treatment exceeded the leaf content of the active compounds in the volatile oil, including Linalool, Limonene, Geraniol, and α-Pinene, it gave 4.175%, 1.168%, 29.640% and 1.625%, respectively. The interaction treatment between biological and chemical fertilization gave a significant superiority in the dry matter percentage of the root group and the leaf content of Linalool, Limonene, Geraniol and α-Pinene.
