Nouvelle technique culturale de conduite du caféier robusta; perspectives d'avenir
In view of the very unencouraging management conditions used by the African grower of Robusta coffee and the reticence he often shown when the coffee plants need to be stumped under the five-year pruning system, this technique was used to test some systems that make it possible to delay, or even avoid, the stumping operation. These pruning systems are based upon topping the coffee tree at a height of two metres, using a single-stem system or a multiple-stem system with 2 -3 and 4 vertical axes, and all the topped stems are compared with the standard system in which four stems are allowed to grow freely and are stumped for the first time after seven years, and then every five years. When the yields obtained from topped stems, over twelve succesive harvests, are compared with the yields under the traditional systems (unpruned trees, without stumping or removal of suckers), it is clear that topping is better than the system without any stumping on the small holdings. The mean annual family income, over twelve years, under the traditional system only represents 24,3 per cent of the corresponding income when the stems are topped and 23.0 per cent when the trees are stumped. Furthermore, national coffee production is seriously affected. Very substantial amounts of foreign currency, which could contribute to national development, are lost
