Agriculture experts have instructed farmers to take precautions while harvesting and storing sunflowers. When the backside of sunflower flowers changes from green to golden and the yellow petals turn brown, it must be understood that the crop is ready for harvesting. But it would be better to allow the crop to ripen a little more for mechanical harvesting. In case of manual harvesting, cut the sunflower’s flowers and spread them in the sunlight for 2 to 3 days, and grind them with a thresher. The moisture content should not exceed 8% and straws 2%, similarly clean and store the seeds thoroughly.
