Because the production of apple is greatly affected by weather conditions, the changes of weather conditions must be considered in forecasting yield and quality level of apple.
The purpose of this study is to estimate which weather conditions affect the yield and quality of apple and present methods of improvement in forecasting production of apple.
It is presumed that 1) the yield is determined by weight, width, and length of an apple, 2) the weight is affected by both width and length of an apple, and 3) the weight, width, and length of an apple are affected by the weather conditions like temperatures, the amount of precipitation and solar radiation, and sunshine duration.
It is estimated that the yield of apple has positive relation to the rainfall in November, the lowest temperatures in March, and the duration of sunshine in June to August, but has negative relation to the highest temperatures in September.
The level of sweet has negative relation to the amount of precipitation from July to August, but has positive relation to the temperatures in June to August except the lowest temperatures in July and to the amount of solar radiation in June to August.
