Abstract
After some preliminary investigations and field studies on arable 'Oil-seeds started in 1965 (Ogunremi, unpublished), Sunflower (Helianthus annuus, L.) became one of the newly identified potential alternative sources of vegetable oils in Nigeria. It had not been grown before in any part of Nigeria, the two main traditional sources of vegetable 'oils having been groundnut and oil-palm. The rapid decline in the local production of both groundnut and oil-palm created some problems in meeting the local requirements for vegetable oils. Held studies by Ogunremi (I979) showed that sunflower could fit well into our farming systems, besides being a suitable alternative source of vegetable oil and a likely substitute for groundnut particularly in the southern part of the a country.
