This research was aimed mainly to identify the extension role of cooperatives in the marketing of smallscale farmers' crops through the supply chain and electronic marketing. The research data were collected using a questionnaire thr ough personal interview. A sample of 118 respondents was taken by 5% of the small farmers surveyed in the villages of Koum Al Barkaa, Al Atraby and Al Omaraa. The statistical analysis methods were the percentages, arithmetic average, frequencies, standard deviation , And the coefficient of variance, as well as the simple correlation coefficient, multiple correlation coefficient, multiple regression coefficient, partial regression coefficient, (t) test, and the (f) ratio using the computer through the SPSS program. The most important research results are Folbwing: The decrease af the arithmetic mean of most independent variables, with the increase in the variance between the respondents, and the degrees in the overall scores of the agricultural extension role of the cooperatives in marketing the crops of the small farmers. At the same time it was found that the mean value of the total degrees of the supply chain and electronic marketing for small farmers were 119,53 degree. In terms of multiple regression relationships, it was clear from the regression model that three independent variables are responsible for the interpretation of 38.2% of the total variance in the overall scores of the agricultural extension role of cooperatives in marketing the crops of small farmers as a dependent variable at the probability level 0.01. Between multiple independent variables regressions relationship, supply chain and electronic marketing that there is a dependent variable and independent variables collectively responsible for the interpretation of 26.8% of the total variation in total incident degrees supply chain and electronic marketing of Small farmers Crops both in dependent variables at the potential level .01.
