Abstract : The difficulty in planting fruit and multipurpose trees in semiarid areas results from water requirements, immediately during planting and the entire period of growth. A new irrigation method with vertical semi-tube, tested in Senegal, permits to water young plants with low water quantity and to grow in these semiarid areas. With the success of this method, the extension of orchards of mango and cashew trees induces a fruit production risk that can saturate the market in a short-term if the fruit production chain is not structured in due time. The new irrigation method is described and the urgency to organize the producer groups and the fruit production chain is established.
