The life cycle of wheat includes production, use of machinery and application of agricultural chemicals such as pesticides and fertilizers. This study was done to evaluate green house gases (GHG) emission of Varieties Rice under Traditional and Semi-mechanized Farming Systems in guilan province (north of Iran). For this purpose data were collected by using a face-to-face questionnaire during 2010 years. The comparison of calculated and measured amounts of green house gases emission were showed that breed varieties higher green house gases emission than local varieties. Also, The comparison of calculated and measured amounts of green house gases emission were showed that semi-mechanized system higher green house gases emission than traditional system.
