Global warming and greenhouse gas emission are one of the important researches in recent years. There are a wide range of greenhouse gas resources and one of them is agricultural activities. During agricultural activities CO2 emission from soil occurs. Water requirement in plant production is met by using various irrigation methods. The most widely used methods are drip irrigation, sprinkler irrigation and surface irrigation. Drip irrigation in recent years has been preferred due to its less water use. This study was carried out to determine soil CO2 emission in apple orchard of Jersey Mac apple cultivars grafted on M9 which was irrigated by drip irrigation, sprinkler irrigation and surface irrigation methods.
