Abstract
The aim of this research is to estimate the production function of peanut in Diyala governorate and to analyze the economic efficiency of studied parameters . Statistic sample with 150 farmers was applied . Results indicated that logarthmetic function was the best representative of the relationship between production and independent variables (cultivated area , quantity of seed , fertilizer , herbicides , number of irrigation and labor services). R2 was 0.77 which means that 77% of the variation in peanut production in contributed to the variation of descriptive variables. Results also indicated that all variables were significant but fertilizer . Sum of elasticities was (1.4) representing increasing return to scale. According to marginal productivity and average productivity of variable, production process was in the second stage . The study of economic and social propertiy of sample revealed thay primary education was dominant among farmers of penut ratio of them was 486% whras the ratio of illiteracy wes 16% of total farmers folloed by graduate ofsecondary syage of 14% the hnstitute graduate can in the third stage 12 % the owning category that wes more distributed wes 11_20 D which wes more than 35% of overall of cultirated area
