                            <p>The aim of this study is forecasting the honey production amount in Turkeyfor 1950-2014 period by practising upon the data for 1950-2014 period and determining the best model type. It was seen in the study that the difference of the series itself from the autocorrelation function graph were not stable and the series became stable after the first difference was taken. Augmented Dickey-Fuller test was carried out for the stability test. Model predictions were made from previously tested models whose parameter predictions were significant and AkaikeInformationCriterion (AIC) and Schwartz Bayesian InformationCriterion (BIC) values were the lowest. The most appropriate prediction model defined for the honey production is the one called ARIMA (0,1,1) which is an integrated moving average model with a first degree mobility. In accordance with this model, it is predicted that the honey production inTurkey will increase consistently from 2015 to 2020 and the number in 2015 will be 100 501 and107 887 in 2020.</p></trans-abstract>

Bunun için, 1950-2014 döneminin baz alındığı bal üretimi serisinden yararlanılmıştır. Çalışmada, serinin otokorelasyon fonksiyonu grafiğinden durağan olmadığı, birinci fark alındıktan sonra serinin durağan hale geldiği görülmüştür. Durağanlık testi için genişletilmiş Dickey-Fuller testi kullanılmıştır. Denenen modellerden parametre tahminleri anlamlı bulunan ve Akaike bilgi kriteri (AIC) ile Schwartz Bayesci bilgi kriteri (BIC) değerleri en küçük olan model tahminleri yapılmıştır. Bal üretimi için belirlenen en uygun tahmin modeli ARIMA(0,1,1) şeklinde ifade edilen bütünleşik birinci dereceden hareketli ortalama modelidir. Bu modele göre 2014-2020 yılları arasında Türkiye’de bal üretiminin devamlı artış göstererek 2015 yılında 100 501 ve 2020 yılında ise 107 887 olacağı tahmin edilmektedir.</p></abstract>
