Abstract

The aim of this research is to estimate the area unit function of productivity for the potato crop in Anbar province for the autumn season (2008 / 2009) Anbar province has been chosen as an applied model for the study due to its well known in cultivating potato crop , and the data were collected through a random sample about (10%) from the study society with a (150) farmers,  The results indicated that the double logarithmic formula was the best representative of the relationship between crop productivity and independent variables (quantity of potato tubers , quantity of herbicides stuffs, quantity of fertilizer , hours of mechanical labour , hours of human labour and number of irrigation water in  season ) according to economic theory as well as statistical tests , counterpart to reliance Cross-Section Data the model has including the problem (Heteroscedasticity ) , ( R2 ) (0.75) , which means that (75%) of the changes in potato productivity  caused by on input factors in model , The results indicated that all variables were significant at level(1%) except fertilizer,  according to (t) test, The total productivity elasticity’s shown which is (1.327) returns to the increased capacity, area unit average productivity for the potato crop was(2.7568) ton per dunam for the autumn season.
