Cassava is among the food crops that tolerate soil acidity well; therefore, it is often planted on highly acid, unfertile soils without fertilization or liming. Nevertheless, cassava needs large quantities of P for maximum productivity. In fertilization trials at Carimagua (Llanos Orientales, Col...
The possibilities of underdeveloped countries to satisfy their needs for food and to improve the standard of Eving through cassava production are analyzed. The following aspects are studied: potential cassava production (current and potential situation), general research policies and areas (var. ...

A major argument put forward in favour of individualised land rights in sub-Saharan Africa is that farmlands held under exclusive and secure rights are more productive than farmlands held under other public or customary forms of tenure. If true, this argument implies that reforms to individualise...
