This study deals with t11e study of agiicultural mechanization and its relationship with agiicultural production in Vientiane Municipality, Laos. The study is based on data collected tlu·ough a smvey of 48 fa1mers from 10 villages spread in four dist1icts in Vientiane Municipality. Fanns were divided in two main categories: fatms using power tillers, and traditional fa1ms using animal drawn implements. The power tiller users were further divided into tlu·ee sub categories as the fatmers who own power tiller and using them in dry and rainy season, the fa1mers who hired power tillers in both rainy and dty season and the farmers who own power tiller and using them in rainy season only. The traditional farmers using animal drawn implements grew crops in rainy season only due to lack of inigation facilities. The main crop is rice. The main sources of fann power are human labour, draft animals and power tiller. The average holding size for 48 selected farmers was 2.15 hectare of which on an average 1. 79 ha was cultivated during rainy season and 1. 58 in dry season. The yield of paddy crop varied between 2.3 to 5. 8 tons per hectares for the dry season and between 1.4 to 4. 8 tons per hectare for the rainy season dee crop. The fa1mers who own power tillers had the highest average yield of paddy 3.24 t/ha in rainy season and 4.10 t /ha in dty season followed by the fatmers hi.ting power tiller. The cropping intensity of fatmers having irrigation was higher than those with out inigation. The cropping intensity offatmers who own power tillers was 187%, it was 172% for the farmer who hires power tillers. In case of fatm without irrigation, the cropping intensity was 100% for farmers owning power tillers and for the traditional fatms where only one crop in rainy season was taken. The Family income of farms using power tiller was higher than the family income of traditional farmers using animal drawn implements.
