Evaluation of Climate-Drought-Yield Relationship on Wheat (T. aestivum L.) by Krigging Method in Turkey

The purpose of this study to classify similarities/dissimilarities of provinces and to determine the potential of provinces on wheat for rainfall, temperature (maximum, minimum and mean temperatures), yield and drought by Krigging method in Turkey. Important relationships appear between acreage, production and crop yield. Climatic factors (rainfall, minimum, maximum and mean temperatures) seemed main determiners to built drought and to yield and production of wheat. Particularly rainfall is most efficient factor on drought and crop yield. Drought, diseases, lodging and winterkill could be assumed as major determinants in wheat crop production in Turkey. Besides, climatic, topographic and soil conditions are very significant factors in determining yield and production of wheat.
