Abstract: (319 Views) |
Organic fertilizers and mulching materials, as an alternative to chemical fertilizers in plant nutrition and improving soil conditions, are among the principles of sustainable agriculture in environmental protection. The purpose of this study was to investigate the effects 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 conducted using a factorial experiment in a completely randomized block design with four replications. Sixteen treatments were evaluated, 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 significantly impacted plant height at the 1% significance level, with the tallest plants reaching 44.8 cm under vermicompost treatment and the shortest at 30.8 cm in the control group. The effect of different mulch types on plant height was also 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 cm 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. The dry weight and fresh weight of N. schoberi under vermicompost fertilizer were 188 grams and 340 grams, respectively, the highest among all treatments. Overall, the use of straw and stubble mulch and vermicompost, or their combination, had the most significant impact on the functional characteristics of N. schoberi. Therefore, based on the results, it can be concluded that planting N. schoberi along with the application of vermicompost fertilizer and straw and stubble mulch can significantly enhance the growth of this species. Moreover, this approach proves effective in addressing dust-related issues and restoring the shores of Lake Urmia.
