Abstract EN

This study was conducted during September 2018 to May 2019 at the Lath house, belong to Horticulture and landscape Department / College of agriculture / Kirkuk university, to study the effect of foliar spraying with seaweed extract (Acadian) at different concentrations (0, 1, 2) g.

L-1 on the growth, and Yield of two Saffron Cultivars (Crocus sativus L.

)first cultivar (Bunch)and the Second cultivar (Pushal), The study was laid out in factorial Randomized Complete Block Design (R.

The results showed that spraying with seaweed extract (Acadian) at (2) g.

The two cultivar did not differ significantly in their studied characteristics.

The Interactions between the spraying levels with seaweed extract (Acadian) and Cultivars had a significant effect on improving most of the studied traits, as it gave the treatment spraying with seaweed extract (Acadian) (2)g.

L-1 and Cultivar (Pushal) increased of number of shoots(5.40) bud.

with the highest content of total chlorophyll (1.84)CCI, and highest number of Cormels (3.20) Cormel.

plant-1, highest of wet weight of the Cormels (2.28) g, while the cultivar (Bunch) was superior to the concentration of 2 g.

L-1 in the highest number of Corms (4.33) Corm.
