Climate changes have sever threats on food security in subsistence farming systems of Burkina Faso where agricultural production is strongly base on rainfall. Soil and water conservation techniques such as zaï and improved seeds of sorghum (Sorgum bicolor L.) were tested and adopted in the drier zones of the North as adaptation technologies to the climate changes. The aim of this study was to assess the performance of the combination of improved sorghum variety (Sariasso 11) with zaï technology on its yields performance in the context of climate changes. The trail was conducted in field conditions and 10 farmers were concerned. The different treatments were randomly distributed according to a Fisher block design with 4 treatments and 5 replicates in the villages of Loaga and Sika. Measurements were carried out on the components of sorghum yield, and soil parameters. The results showed that the treatment « zaï compost + improved seeds» adapt better to the climatic changes. It allowed a better development of the sorghum and grain yield increased by 3 compared to the control. Chemical parameters of the soil were significantly improved, and the pH reached a value of approximately 6.5 in this treatment. The combination of the two techniques permits therefore to improve the resilience of the agricultural production facing the climate changes.

Abstract: (french)
Les changements climatiques constituent une menace sérieuse pour la sécurité alimentaire des pays pauvres où la production agricole est étroitement liée à la pluviométrie. Des technologies de conservation des eaux et des sols comme le zaï et l’utilisation des semences améliorées de sorgho (Sorgum bicolor L.) ont été éprouvées et adoptées dans les zones plus sèches du Nord comme des technologies s’adaptant aux changements climatiques. Dans cette étude, il s’est agi d’évaluer la performance de la combinaison de la variété améliorée de sorgho (Sariasso 11) avec le zaï dans le contexte des changements climatiques. Un dispositif en blocs de Fisher complètement randomisé avec 4 traitements et 5 répétitions a été installé en milieu paysan avec 10 producteurs. Les observations ont porté sur l’évaluation des composantes du rendement du sorgho. Des échantillons de sol ont été prélevés, puis quelques paramètres chimiques ont été déterminés. Les résultats montrent que le traitement « zaï compost + semence améliorée » s’adapte aux changements climatiques. Il a permis un meilleur développement du sorgho et une augmentation des rendements en grains de 3 fois par rapport aux témoins. Au niveau des propriétés chimiques du sol, le pH a atteint une valeur avoisinant 6,5 dans les poquets de zaï et la matière organique du sol a été améliorée. . La combinaison des deux techniques permet donc d’améliorer la résilience de la production agricole face aux changements climatiques.
