Sunflower Harvesting

i. Cut the capitula (flower heads) only
ii. Thresh and clean
a. Immediately after harvest, dry the heads in the sun for 3 days.
b. Spread the heads in thin layer and give turning once in 3 hours.
c. Thresh using a mechanical thresher, or beat with a stick and separate the grains.
d. Winnow and clean the seeds
e. Dry the seeds again in the sun for another two days
f. Store in gunny bags

NOTE: Do not heap or store the heads before drying properly as mould fungi will develop and spoil the grain quality.
