Workshop on Berry Production in Changing Climate Conditions and Cultivation Systems, Geisenheim, Almanya, 01 Temmuz 2009, cilt.838, ss.59-61
Erzurum city located in the Eastern Anatolia Region in Turkey is characterized by a high altitude (around 2000 m a.s.l.) and a very short vegetation period. For these reasons, the strawberry harvest period starts at the beginning of July and ends in early October. The day-neutral cv. 'Fern' was the main cultivar used in commercial production. In the last years, climate change was observable in this region. The aim of this study was to discuss the possible results of the climate change on strawberry yield in the Erzurum region according to long term, 2006-2007, and 2007-2008 meteorological data and a field experiment with cv. 'Fern' during two years (harvest of 2007 and 2008). The data showed that on one side the winter before the harvest of 2008 had only 78 snow-covering days in contrasts to the 110 days in the winter 2006-2007. On the other hand, the summer 2008 was unusual because the night temperatures were increased in average by 4 degrees C in comparison to 2007. However, the warmer conditions in 2008 did not have a positive effect on fruit yield, because the decrease in snow-covering days during the previous winter negatively affected strawberry plants (yield of 13 tons per ha in 2008 and 19 tons per ha in 2007).
