The serious food crisis that afflicting many states assume to make it a natural trend of agricultural policies geared towards addressing the factors that affect productivity growth, which is studied and related urgent need.

The aim of this work is to study factors affecting peanuts productivity by taking a random sample of 150 farmers in Diyala province in Iraq.

The result showed that the double logarithmic function was appropriate with the economic meaning, by representing the relationship and passing statistical criteria.The dependent variable represented by productivity of hectare, and the independent variables contain: harvested area, mechanical work, fertilizers ,seeds ,irrigation ,experience of peanuts cultivation, pesticides and the education of farmers.

The independent variables explained about 53% of variations in the productivity.The result also showed the significance of all independent factors except education,and showed that irrigation was the most factor affecting productivity because the crop needs a huge quantities of water during cultivation period and the value of parameter 0.43,that’s mean if irrigation changed by one unit ,the productivity will change with 43%.The variables: mechanical work and fertilizers follow irrigation and the value of their parameters 0.24,0.25 perspectively.When making a comparison between productivity of peanut in Iraq and other countries,we found that productivity in Iraq is the same as other Arab countries,where Egypt come first with3.1 ton/ha but it is too low against other world countries,where USA come first with 3.3 ton/ha of productivity and that is indicate problems in this crop cultivation in Iraq.
