What yield and income can marigold for extraction give per acre and what are the main problems?

Extraction marigold is grown for high flower tonnage, and African hybrids can give a good flower yield per acre over multiple pickings, but the figure is a range that depends on variety, season, irrigation and management, so verify the expected yield and the buyback rate with the contracting company and other growers rather than trusting a headline number. Income is driven by total flower weight times the contract price, minus any quality rejection, so realistic income is a range, not a fixed promise. The main problems to expect are pest and disease pressure, especially flower bud damage and leaf diseases, the need for steady picking labour since flowers must be harvested at intervals, transport of bulky fresh flowers to the collection point on time, and the risk of price or rejection disputes under the contract. Plan picking labour and transport carefully, and confirm yield, price and the exact quality terms locally before committing.
