The effect of using dry microalga (Chlorella vulgaris) as soil additives on the nutrient status and shoot and root growth of maize plants (Zea mays L. var. Triple-hybrid 310) was investigated. Algae were added to the soil before sowing in the rates of 50, 100, 150 and 200 Kg /Fed, in addition to the basic NPK fertilizers. Significant increase in the nutrient taken up by shoots and roots was calculated as a result of adding different alga-levels. Addition of algae has significant increases in root volume, chlorophyll formation, dry weight of shoots and roots as well as plant height. The best treatments were 150 and 200Kg algae/Fed.
