| Abstract | ABSTRACT In this study the relationship between hazelnut yield and climatic conditions were analyzed. Black Sea Region, Turkey, is one of the most favorable habitat for hazelnut cultivation in the world. Having the highest economic value among various hazelnut cultivars cultivated in this region, Tombul hazelnut finds the optimum conditions- principal of these conditions is the climate one- in Giresun. Therefore, with the assumption that it can be accepted as the most suitable sample for this study, Giresun was selected. The time period between 1993 - 2007 which included reliable data on climate and production was analyzed. Among many factors effective on yield, climatic conditions have a principal role. With this purpose, the special climatic requirements of hazelnut during its each phenological period were examined and their effects on yield were analyzed. This analysis was made in two ways. The first one is the special climatic requirements analysis and the second one is the correlation and simple linear regression analysis. In the former the effect of daily, monthly and annual meteorological data in accordance with hazelnut’s special climatic requirements on yield was analyzed year by year. In the latter, the correlation between climatic variables and yield was analyzed and then simple linear regression was performed. According to both analyses, the most considerable climatic variable affecting the yield was determined as temperature. Keywords: hazelnut, climate, correlation and simple linear regression analysis, Giresun (Turkey). OZET Bu calismada findik verimliligi ile iklim kosullari arasindaki iliski incelenmistir. Findik yetistiriciliginde Dunya’da en uygun alanlardan birisi Karadeniz Bolgesi’dir. Bolgede yetistirilen findik cesitleri icerisinde ekonomik degeri en yuksek olan findik Tombul findik olup, en uygun kosullari, ozellikle iklim kosullarini Giresun’da bulmaktadir. Bu sebeple calisma alani olarak Giresun ili secilmistir. 1993 – 2007 donemine ait guvenilir iklim ve findik uretimi verileri analiz edilmistir. Findik verimliligi uzerinde etkili olan bircok faktor arasinda, en onemli faktorlerden birisi iklim kosullaridir. Bu amacla, findigin fenolojik donemlerinde ozel iklim istekleri incelenmis ve bunlarin verimlilik uzerine etkileri analiz edilmistir. Bu analiz iki turlu yapilmistir. Birincisi ozel iklim istekleri analizi, ikincisi korelasyon ve basit lineer regresyon analizidir. Oncelikle, findigin ozel iklim isteklerine bagli olarak gunluk, aylik ve yillik meteorolojik verilerin verimlilik uzerine etkisi yildan yila analiz edilmistir. Sonrasinda, iklim degiskenleri ve verimlilik arasindaki korelasyon analiz edilmis ve basit lineer regresyon denklemi uygulanmistir. Her iki analizin sonucuna gore; findik verimliligini etkileyen en onemli faktor olarak sicaklik olarak tespit edilmistir. Anahtar Kelimeler: Findik, iklim, korelasyon ve basit lineer regresyon analizi, Giresun. |
