Nuts play an important role in Tunisian fruit tree production. The most important crops are almonds and pistachios. Almond production is mainly for domestic consumption, although a small part is exported. A great deal is also commercialised fresh. Pistachio production is still at an early stage despite its promising possibilities. Walnut and hazelnut are of limited significance although their potential for future development should be considered. Nut production still has certain constraints such as irregular yields, high production costs and variable quality.
