Abstract
The study was conducted at a private field north of Basra Governorate during the growing season 2019 with objective of exploring the effect of three seaweed extracts (Agazone, Agrosign and Alagen) at a concentration of 1ml per liter and three application methods (soaking seeds, spraying plants and soaking seeds +spraying) on growth, flowering and yield of Okra. The results indicated that soaking seeds+ spraying the plants gave the highest values of vegetative and flowering growth characteristics compared to the other methods. Also, the results showed that Alagen extract gave the highest values in plant height, number of leaves and the percentage of flowering .Whereas the highest values resulted in leaf area, number of branches, number of flowers and total fruit weight of plant were resulted from the use of the Agrosign extract. The interaction between both factors was significant on vegetative growth and yield characteristics.
Key words: Agazone extract, Agrosign extract, Alagen extract, Okra.
