摘 要：<p align="justify"> <span style="font-family:Verdana;">Soil salinization is one of the major causes of land degradation. In Senegal, this phenomenon continues to grow, making soils unsuitable for agriculture. To rehabilitate salty lands, one of the recommended strategies is the use of salt-tolerant plants. Among them, plants of </span><i><i><span style="font-family:Verdana;">Casuarinaceae</span></i></i><span style="font-family:Verdana;"> family form a relationship with symbiotic microorganisms such as arbuscular mycorrhizal fungi and nitrogen fixing bacteria. It has been shown that symbiotic microorganisms play an important role in the establishment of tolerant plants in saline conditions (Djighaly </span><i><i><span style="font-family:Verdana;">et al</span></i></i><span style="font-family:Verdana;">., 2018). They improve plant performance and reduce transplant shock under salt stress conditions (Diagne </span><i><i><span style="font-family:Verdana;">et al</span></i></i><span style="font-family:Verdana;">., 2014). These microorganisms can be used as biofertilizers. However, inocula containing symbiotic microorganisms are either too expensive or unavailable in many developing countries. The aim of this study is to test alternatively affordable and low-tech solutions to promote symbiotic interactions such as Casuarina crushed nodule, Casuarina rhizosphere soil and Casuarina leaves compost that may contain symbiotic microorganisms and also nutrients such as N and phosphorus. Two species of Casuarina (</span><i><i><span style="font-family:Verdana;">Casuarina equisetifolia</span></i></i><span style="font-family:Verdana;"> L. and </span><i><i><span style="font-family:Verdana;">Casuarina obesa</span></i></i><span style="font-family:Verdana;"> Miq.) were grown in the greenhouse on sterile soil to which an amendment was added (Casuarina crushed nodules, Casuarina Rhizospheric soil or Casuarina leaves compost). Plants were subjected to saline stress.
