Abstract

The study investigated the potential of Chlorella vulgaris to promote agricultural plant growth while inhibiting pathogenic microorganisms. Chlorella algae, purified from the Al-Gharraf River and cultured on Chu-10 medium, were examined under different conditions. The use of urea fertilizer led to varying Chlorella numbers across growth stages, with increases in early stages and a subsequent decrease. Additionally, three urea concentrations (3%, 5%, and 10%) were compared with a control treatment. Results showed Chlorella numbers reaching 50 cells per 100 mL on the seventh day and 400 cells per 100 mL on the fifth day. While the optimal cultivation conditions for Chlorella vulgaris were explored, revealing daylight, a temperature of 25°C as conducive to algae growth. The effective culture medium consisted of the Chu-10 medium. This research suggests the potential of Chlorella biomass for creating biopesticides and growth stimulators.
