Effect of soil type and salinity on growth, yield and chemical composition of Artemisia annua plant. Artemisia annua L. (A. annua) plant belongs to family Asteraceae. It has several biological properties and important bioactive constituents were isolated from A. annua such as artemisinin and essential oil. Salt stress and soil types are the most environmental factors, which has a very high impact on growth, yield and metabolism of medicinal and aromatic plants. More than nineteen percent of different agricultural soils in Egypt have salts as well as irrigation water. In such conditions cultivation of resistant medicinal and aromatic plants is one way to utilize these soils. Therefore the selection of suitable plants, which could cope with these conditions, is a necessity. In this investigation the possible effects of saline irrigation water and / or soil types on the growth, yield and chemical composition of A. annua were evaluated at the Experimental Farm, Faculty of Agriculture, Cairo University and National Research Centre (NRC), Egypt, during 2014 and 2015 seasons.Artemisia annua plants were exposed to different levels (0.0, 1.6, 3.2, 4.7, 5.3 and 7.9 dS m-1) of saline irrigation water (SIW) under two soil types (clay and sandy loam). Growth characters (Plant height, branch number, fresh and dry mass) as well as chemical composition (essential oil content, artemisinin, photosynthetic pigments, total carbohydrates, total soluble sugars, proline, total flavonoids, total phenolic compounds, free radical scavenging and mineral contents) were recorded
