Organic fertilizers and mulching materials as an alternative to chemical fertilizers in plant nutrition and improving soil conditions are one of the principles of sustainable agriculture in environmental protection. The purpose of this study is to investigate the effect of some organic fertilizers and mulch on the morphological characteristics (plant height, root length, dry weight, fresh weight, number of leaves and number of lateral branches) of Nitraria schoberi grown on the shores of Lake Urmia. The research was carried out using a factorial experiment in a completely randomized block design with 4 replications. The study evaluated 16 treatments, including light mulch (1 kg per plant), dark mulch (1 kg per plant), straw and stubble (2 cm thickness per plant), chicken manure (1.5 kg per plant), cow manure (1.5 kg per plant), vermicompost (1.5 kg per plant), a combination of mulch and fertilizer (1.5 kg each per plant), and a control treatment. The study revealed that vermicompost fertilizer significantly impacted plant height at a 1% level, with the tallest plants reaching 44.8 cm using vermicompost and the shortest at 30.8 cm in the control treatment. The impact of different mulch types on plant height was statistically significant at the 1% level. The tallest plants, reaching 50.01 cm, were observed with straw and stubble mulch, while the shortest heights of 37.6 and 38.4 cm were associated with dark and light mulch, respectively. The straw and stubble mulch treatment produced the highest leaf count of 411 compared to other treatments. Dry weight and wet weight of N. schoberi under vermicompost fertilizer were 188 grams and 340 grams respectively, the highest among treatments. Overall, the use of straw and stubble and vermicompost or their combination had the most significant impact on N. schoberi's functional characteristics. Therefore, according to the results, it can be concluded that planting N. schoberi species along with the application of vermicompost fertilizer and mulching with straw and stubble in its bed can significantly contribute to the growth of this species. Moreover, this approach proves to be effective in addressing dust-related issues and restoring the shores of Lake Urmia.
