The present study was carried out to record and report the phtototoxic effect of Suaeda fruticosa extract on germination of Abelmoschus esculentus and Brassica oleracea. Sueda fruticosa is an evergreen small much branched succulent Shrub growing to 1 m; in saline soil of xeric habitat of District Bannu. This plant has inhibitory effect on germination of radicle and plumule of seed. In this study the effect of different concentration (0 mg/ml, 5mg/ml, 7mg/ml, 10mg/ml) of shade dry leaf methanol extract of Suaeda fruticosa on germination of Abelmoschus esculentus and Brassica oleracea were investigated. The results showed that the methanol extract of this plant gradually decreased the germination percentage, especially at higher concentration. The radicle and plumule length were also affected by different concentration. Maximum growths were occurred at control Petri dish; the growth decreased as the concentration of extract increased; growth become Minimum at higher concentration. The same results were observed in the field by apply the same amount of methanol extract of this plant. It is concluded that presence of Suaeda fruticosa in the field may retard the germination and seedling of Abelmoschus esculentus plants and Brassica oleracea. It was also show that no growth occurs at higher concentration.
