It is one of the most drought-tolerant crops, capable of growing on marginal soils, plays a particularly important role in agriculture in developing countries, especially in sub-Saharan Africa.
Currently, about half of the world production of manioc is in Africa. It is cultivated in around 40 African countries. Around 70% of Africa's manioc output is harvested in Nigeria, the Congo and Tanzania.The use of high-quality fertilizers significantly increases its yield.
