The groundnut is widely grown in Uganda as a food and cash crop. It is one of the highest paying crops with fairly stable prices. It is grown in nearly all parts of the country but especially in eastern Uganda and Northern regions. Household consumption is quite high with preferences to the brown/red-kenneled varieties because of their reputed taste. In addition, there is a huge informal trade at the borders. The Kenyan market demands small-white and big-white varieties. Because of the importance of groundnut, the demand far exceeds output. Thus the need to increase yields and acreages. Well managed plots and high yielding varieties could go a long way to achieve this. This manual provides information on good agronomic and post-harvest handling practices of the groundnut. Adopting such practices would help increase groundnut crop production considerably.
