Iranian Saffron is one of the products that have been commonly cultivated in south Khorasan since ancient times. It is the most suitable crop for the high density planting system in remote and deprived parts of the country. Because most of the country’s saffron farms are located far from the center of the country and lack industrial and other manufacturing facilities. One of the characteristics of these parts is water scarcity. Saffron is considered as an over-strategic product in the central and south Khorasan regions.
Iranian Saffron requires low quantity of water than most other crops and it is a perennial plant and maintains its productivity feature from five to seven years. In addition, remarkable saffron characteristics such as its product durability for a long time, the ease of transportation, no need for heavy machinery and sophisticated technology, its potential to absorb a lot of labor at harvest time, the increasing need of it for the industrial, pharmaceutical and nutritional usage have led to the Iranian Saffron cultivation development and high saffron price.
