Abstract :

This study was undertaken to compare the effects of some organic fertilizers and chemical fertilizer applicatios of fruits in strawberry in Erzurum condition at research area of Horticulture Department of Agriculture Faculty of Ataturk University between 2010 and 2011. First class of Fern strawberry cultivar frigo seedlings which grown in organic condition were used as plantal materials in the experiment. The Experiment was conducted based on Completely Randomized Design arrangement with three replications and each replicate had 40 plants. In the study, NPK (8-5-10Ec Fertilizer) liquid chemical fertilizer for conventional growing, Makro Crop,Stym 25, Biofarm and Mol organic certificated commercial fertilizer and organic farmyard sweetened for organic growing wereapplied as fertigation in strawberry growing. According to research results, TSS, total sugar and vitamin C contents were higher in organic fertilizer application when comparing to conventional fertilizer. While the highest vitamin C content (126,67 mg/100 ml) was Biofarm organic fertilizer application, the lowest value was determined as (72,53 mg/100 ml) in control application in 2011.Conventional application had 97,67 mg/100 ml vitamin C content. The highest nitrite and nitrate contents were determined in chemical fertilizer application while the lowest value was reported in Stym 25 organic fertilizer.
