Note générale :	This document comments a cereal production in Senegal. Then, it's about an average demand is projected to increase by 24, 000 mt /year between 1975 and 1980 and 28, 000 mt/year between 1980 and 1985. Increased urban demand will account for about 46 per cent of the increase to 1980 and 50 per cent to 1985. Agronomic work on farmer's fields is limited and more is needed. It appears that on farm fertilization with N and P gives a cereal response of 7-15 kg of grain per kg of nutrient. At 1976 farmer princes, this gives a return of 5-10 times the investment in fertilizer.
