| Abstract:
Pistachio is the most important agricultural crop cultivated extensively in Iran’s dry zones. The country earns sizable income from pistachio export to many countries. This paper aims to study the production and export growth of pistachio in Iran. Time series data on area, yield, production, export quantity and export values collected for the period 1991-2002. Exponential trend equation was used for the aim of the study. The growth rate of area planted was 5.12% and significant against non significant values for production, yield, export quantity and export values for the whole study period (1991-2002). In first sub period (1991-1996) except yield which had a non-significant growth rate, the other factors had significant and positive growth rates. In second sub period (1997-2002) it was the only area which experienced a positive and significant growth rate of 2.33%. | |
