Abstract
Abstract The experiment was carried out under the shade net house conditions in a private farm located in Al-Diwaniyah city, Al-Qadisiyah, Iraq to investigate the influence of applying different rates of seaweed extract (0, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 g/L) on different plant growth parameters and flowers production of gerbera ( Gerbera jamesonii L.) plant. Results showed that there were statistically differences in the levels of seaweed extract that applied as a source of organic fertilizer, and also applying seaweed fertilizer has been increased the agronomic traits and number of flowers produced per plant. It can be concluded that applying of seaweed fertilizer at 3.0 (g/L) had beneficial influenced on the growth and flowering production of gerbera plant grown under the shade net house conditions.
