Effect of Foliar Application with seaweed extract (Acadian) on growth and Yield of two Saffron Cultivars).(Crocus sativus L

Abstract

"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.C.B.D.) with two factors and each treatment consist of three replications . The results showed that spraying with seaweed extract (Acadian) at (2) g.L1, increase significant in the number of shoots(4.86)bud.plant-1 and leaves / Plant(11.30)leaves. plant-1 . with the highest content of total chlorophyll in the leaves (1.79) CCI , and highest number of Corms and Cormels (4.23 Corm. plant-1 , 3.03 Cormel. plant-1) respectively , highest of wet weight of the Corms and Cormels (5.13 , 2.25) g , respectively and the highest diameter of the Corms (3.27) cm . 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.plant-1 and leaves / Plant(12.20) leaves. plant-1. 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. plant-1 , highest of wet weight of the Corms (5.57) g , with the highest diameter of the Corms (3.29) cm "
