North Khorasan province is one of the largest producers of oil seeds, including sunflower.

Early autumn is the time for harvesting sunflower in North Khorasan.

Sunflowers are harvested when their petals become dry and begin to fall. The green base of the head will turn yellow and eventually brown. 

Seeds will look plump and the seed coats will be fully black or black and white stripes depending on the variety. 

The largest sunflower fields are located in Bojnourd, Shirvan, Esfarayen, Maneh and Samalghan, Jajarm, Garmah, and Raz and Jergalan regions.

Vast areas of the province are dedicated to the cultivation of cereals including wheat and barley, as well as cotton, sugar beet, sunflower and forage like alfalfa and corn.
