Response Two Strawberry Cultivars (Fragaria × ananassa Duch.) for foliar Application of Algae and Iron chelate Fertilizers

Abstract

 The beginning of this study in the seasons of 2021-2022 from the orchard at agricultural training center in Erbil /Ministry of Agriculture / Kurdistan Region/ Iraq, The experiment examines the impact of Algae and Iron Chelate at three doses on growth, blooming, and yield as a foliar spray and their interactions on growth, chemical composition, production, and quality of strawberry at two strawberry cultivars (Fragaria x ananassa Duch.). Festival and Sabrina, using the six spraying while doing the experiment in the morning start in November 10 2021 to January 1 2022. The results showed The effect of fertilizer (Algae and Iron chelate) were significantly effect on leaf area, the value was (9.94) were obtained from Sabrina cultivar by using (6gm.L-1 algae and 2ml.L-1 iron chelate). and significantly Effect on fruit size, the value of fruit size is registered with Festival, (6 gm.L-1 algae) and (2 ml.L-1 iron chelate) which are (12.37). Also by spring (6gm.L-1 algae and 2ml.L-1 iron chelate), recorded the anthocyanin's value significant value (16.71 mg.100g-1 F.W.). Additionally, the relationship between (Cultivars + Fertilizers + Concentration) was significantly affected on leaf area, the value recorded in (sabrina + 6 gm.L-1 algae + 2ml.L-1 iron chelate) (14.46 cm2).  Also was significantly affected on fruit size, the value was recorded in (sabrina + 6 gm.L-1 algae + 2 ml.L-1 iron chelate) (13.04) in comparison with untreated strawberry cultivars, on the interaction among (Sabrina + 6gm.L-1 Algae + 2ml.L-1 Iron chelate) obtained the value (10.06 mg.100g-1 F.W.), which obtained from the (sabrina + 0.0 algae+ 0.0 iron chelate).
