Résumé : Change in cotton oil production depends mainly upon change in seedcotton production. Area devoted to seedcotton production in the world has been stagnating for decades while yield has also come to stagnate since mid-1980s. Increase in cotton oil production would derive mainly from seedcotton yield improvement. In economically developed countries, yield is stagnating at a somewhat high level, existing high performing technical packages are fully applied and the challenge being set is to carry out new packages to enhance the yield potential. In developing countries where smallholder production dominates, it is now fully recognized that many technical practices being recommended to smallholders are not relevant as regard these farmers' liquidity constraint and risk adversion while they are submitted to climatic hazards in addition to impediments in input and credit provision. Research work must then begin with taking into account these contraints in order to carry out new technical packages less demanding in cash expenses, more cost effective, providing better protection against climotic hazards and cotton pests. As in many developing countries, cotton is grown under rainfed conditions, tolerance to occasional drought is of major importance. CIRAD has contributed to accertain that the above research objectives are not unrealistic. CIRAD has implemented the approach called "direct sowing over vegetative cover" during the lost decade. This paper states the principles of the approach, exposes the results obtained in Brazil and Madagascar and suggests the assumed phenomena that reverse a negative trend of soil degradation leading to yield unstability and profitability decrease into a positive process of soil improvement and higher input efficiency to ensure better profitability. Finally, relevance of experimenting the approach in Mozambique is discussed.
