Analysis the factors influencing on Cuminum cyminum production productivity in Khorasan province

Cuminum cyminum is the important exporting planet in the world. Khorasan province is one of favorable regions for growing Cuminum cyminum. In this study Cobb- Douglas and Transdental method for production functions were used to determine the productivity of factors that used for production of Cuminum cyminum. The results show that there is a significant relation between production and labor, fertilizer and seed. Farmer don’t use optimum combination of them for production Cuminum cyminum. Optimum combination of labor fertilizer and irrigation water inputs were computed to be 16/63- 554/747and 2 day – labor respectively
