Food loses is one of the main challenges in third countries.The strategic of agriculture is very important in GNP in our country so this is useful for reduling food loses and increasing agriculture produts, making jobs, developing exporting none-oil production and food security. Due to factors such as high per Captia consumption of rice the possibility of agricalturre of rice in specific climatic coudition and rice is Considered. as one of strategic production(Tavalaei. 1375.18) In this research in to consideration the important role of agricultural mechanization in farming of this production paddy case study of 10 rural municipalities from of rice field and farms mechanized caltivation of erditionall Calture, yield and rice production wastes is located. The results showed that yield of treditonal rice farms is 4/8 and in mechanized farms is 5/3 tons per hectar. and cost waste per unit surface in mechanized and traditional farms Respectively is, 2.181,301 and 3,352, 039 rials. In creased yield in mechanized farms to traditional farms is broader levels affected by the mechanization of agricaltuer and traditional varieties application. waste reduction of production of mechanized fram is based on mechanization which is parially affected by the increased yield(Bajvar, 1383.20) He it is the main foundation of divition of villages and house holds is in tomechanized and traditional by the cnteria of the In ternational Rice Research Institute that is desired the carrent conditions and scope of the study and it showed that the only differnc between mechanized and traditional shalikaran is implanting and harvesting operation. Considering the importance of fram area inusing agricultural machines in the present study of the lands is classified in two four groups: Less than one hectar. -1-3 hectars.3-5 hectars-More than 5 heectars. In taditional villages, farms were not more than 5 hectars. So Comparison traditional and mechanized farms among the three group took less than five hectares.
