Description
Onion farming is the main irrigated crop that contributes to the economy of the Tahoua region, Niger. There are two factors that promote the outstanding potentialities of onion cultivation in Niger : the best productive variety “Violet Galmi”, and it is well adapted to storage. It is produced during both growing seasons which creates a permanent local supply of onions all year. Much of the producing areas are not accessible by road, which inhibits the marketing network. Farmers are in need of an improved transportation system in order to further develop onion production. The Violet of Galmi is grown by all the onion producers of Niger. This onion has a major importance in the socio-economic life of the Nigerien population. The consumers appreciate its cooking qualities and spicy taste. It also has a commercial advantage in the local and the sub-regional markets.
