Introduction of jujube tree (Ziziphus mauritiana Lam.) cultivars in the Sahelian zone of Burkina Faso.Abstract --Introduction. The Sahel zone of Africa is characterized by recurring dryness, increased soil degradation, low agriculture yields and frequent periods of famines. It is consequently necessary to introduce crops less dependent on rainfall and able to participate in food self-sufficiency. In this context, we tested improved cultivars of jujube tree in the north of Burkina Faso. Materials and methods. Five improved cultivars of jujube tree of Israeli (Ben Gurion) or Indian (Gola, Kaithali, Seb and Umran) origin were planted in a research station starting from young grafted seedlings (approximately 500 plants·ha -1 ); they were irrigated either by a traditional manual technique, or by a drip system. Fruit weight and dimension (length and width) were studied after 2 and 3 years of plantation. Results. The cultivar yields in the second and third years, irrespective of the cultivar, gave, respectively, 0.48 t·ha -1 and 3.54 t·ha -1 with an average annual production of (0.97 and 7.08) kg per plant. The cultivars Ben Gurion, Gola and Seb produced approximately 500 fruits per plant, Umran, 300 fruits per plant, and Kaithali, 200 fruits per plant. The cultivar Ben Gurion presented the highest average fruit weight (15 g) and Kaithali, the lowest (6 g). The most productive cultivars proved to be Ben Gurion and Gola which, with the cultivar Umran, gave the largest fruits. Discussion and conclusion. The yields observed for the 2-and 3-year-old plants could produce, by extrapolation, a harvest of almost 13 t·ha -1 in the ninth year. These first results obtained in an area not very favorable for agricultural production make it possible to consider the possibility of developing the jujube tree in the Sahelian zone of Africa, and could lead in the long term to a substantial income source for the local populations.
