Cassava is a draught resistant crop and will thrive under low soil
fertility conditions. However, the production of cassava is far below
satisfying the strong demand of the crop for human consumption
and for bio-energy purposes, which often result to strong competition in the satisfaction of both food and energy needs of man. The
statistics of cassava production among countries that are largest
producers of the crop is presented inFig. 1. Africa continent accounts
for about 42% of the world cassava production, while Asia and South
America contribute about 37 and 21%, respectively. The numerous
advantages derivable from cassava crop justify a thorough review of
the existing tillage practices, in order to be able to arrive at a
scientific confirmation of the best soil tillage system for the crop.
