Usually, the sunflower heads are deep yellow, from yellowish-green and the leaves are weathered. The stalk also assumes a yellow colour.
When the sunflower heads are ferried home, the farmer should place them on the tarpaulin and spread out in the sun to dry.
It takes two-five days for the sunflower heads to dry, after which a farmer is advised to use a small stick to lightly hit them for the seeds to drop out, before it is packed in sacks.
The exercise should be done on tarpaulin and not on bare ground. However, a farmer is advised to pile the sacks on top of timber racks, lest the seeds get moist and ferment. The seeds are then sold to a mill, where they are processed into vegetable oil.
- Harvesting is done when the flower heads are deep yellow, leaves are weathered and the stalk yellow
