This study was conducted at Grdarasha Field / College of Agriculture/ University of Salahaddin, Erbil during growing season (2009). The objective of the study was to investigate the effect of foliar application of potassium on the yield components Characteristices of two Varieties of Strawberry (Fragaria X ananassa Duch.) cv. Kaiser's samling and Hapil.
The major results are as following, the content of total chlorophyll and potassium content significantly increased in the concentration (200, 400) mg/L.The interaction between cultivars and K rate of spraying with potassium leaf gave significant result in the content of total chlorophyll and potassium content. And concentration 400 mg/L of spraying with potassium leaf gave significant result in the fruit set, fruit weight, fruit number, and product in plant, cv. Kaiser's samling gave significant result in the fruit set, fruit number, The interaction between cultivars and K rate of spraying with potassium leaf gave significant result in the fruit set, fruit number.But cv Hapil gave significant result in the , fruit weight, fruit number, The interaction between cultivars and K rate of spraying with potassium leaf gave significant result in the fruit weight, fruit number, concentration 400 mg/L of spraying with potassium leaf gave significant result in the TSS, TSS/AC ,Vit. C, cv Hapil gave significant result in the TSS, TSS/AC,Vit. C.
