Banana is exposed to many problems including excessive soil salinity and irrigation waters that decrease productivity. This trial was conducted to evaluate the effects of salinity on the behavior of banana and diversity of fungi in the soil. The trial was installed under greenhouse craft following a completely randomized design with 3 replications. Two banana cultivars (Pelipita ABB and Plantain) were subjected to increasing doses of NaCl (0, 2, 4, 6 and 8 g/ l). The behavior of cultivars, Na and K accumulation in the leaves and the color diversity of fungi were studied. The results obtained show a similar behavior between the two cultivars of banana on the observed parameters, except the leaf area in 15 days, which is high on the cultivar 1. High levels of NaCl decrease leaf area. Significant differences were observed with a high accumulation of Na with T1 and T2 and a high accumulation of K in T5 and T7. Finally the treatments that received low doses of salt have found a high diversity of fungi colors. These results show that the selection of tolerant cultivars is an inexpensive option to increase banana yield on saline soils, in a context where some poor farming practices such as irrigation and mineral fertilization lead to salinization.

Abstract: (french)
Le bananier est exposé à de nombreux problèmes entre autres la salinité excessive des sols et des eaux d'irrigation qui entrainent une chute de sa productivité. Cet essai a été conduit en vue d'évaluer les effets de la salinité sur le comportement du bananier et la diversité de la coloration des champignons dans ce sol. L'essai a été installé sous serre suivant un dispositif complètement randomisé à 3 répétitions. Deux cultivars de bananier (Pelipita ABB et Plantain), ont été soumis aux doses croissantes de NaCl (0, 2, 4, 6 et 8 g/l). Le comportement des cultivars, l'accumulation de Na et K dans les feuilles et la diversité de couleurs des champignons ont été étudiés. Les résultats obtenus montrent que la surface foliaire de Pelipita était élevée à 15 jours que celle de Plantain. L'analyse statique des doses croissantes de NaCl a montré une diminution de la surface foliaire avec les fortes doses. Les différences significatives ont été observées avec une forte accumulation de Na avec les traitements T1 et T2 et une forte concentration d'accumulation de K avec T5 et T7. Enfin les traitements ayant reçu les faibles doses de sel, ont présentes une forte diversité de couleurs de champignons. Ces résultats montrent que le choix des cultivars tolérants est une option peu onéreuse pour accroitre le rendement de bananier sur sols salins, dans un contexte où certaines mauvaises pratiques culturales comme l'irrigation et la fertilisation minérale entrainent la salinisation des sols.
