Abstract: This paper is focused on the statistical assessment of seasonal effects on farmers' income, their workocupation in farm, and sales of apple products. In focus of this study we have taken two regions Prizren and Korça. By making a comparing between Albania and Kosovo, with regard to significance of the model of seasonal effects for apples. In this paper we have used several statistical and econometric methods to evaluate the seasonal effects on economic phenomena taken in the study. We have used the variation indicators to show the distribution of the observed phenomenon. We also have used dummy variable models. Dummy variables are often used in time series analysis, in seasonal and qualitative analysis of applied data. Each dummy variable is set to 1 if the point of datas is received from a specified season and otherwise 0. To evaluate the seasonal effects in a time series through 1dummy variables, we need to use four dummy variables, one for each quarter, or three dummy variables and a constant. These variables use them as inputs or factors in a regression model. In our paper, we have categorized sales, for apples in 5 different periods. To estimate the magnitude of seasonal effects and to test their significansy are used four dami variables. The purpose of this paper is to show whether the pattern of seasonal effects for apples is significant.
