To compare the decomposition rate of leaves and stems Prangos ferulaceae species during a year, this research was carried out at training and research station Hossein Abad of Fars. The litter bag technique with size of 20×20 cm and 2 mm pores was used in this research. Each bag was filled with 5 gr dried plant specimens. Totally 54 bags with leaf, stem, composition of leaf and stem treatments with three replications were placement in the field. Bags were taken at intervals of 60 days (6 times in a year). The amount of nutrients N, C, K, P and C/N in leaves, stems and the composition of leaves and stems were measured after each sampling. The results showed that more nitrogen and lower hemi cellulose in the leaves rather than stems was caused tendency of microorganisms (especially bacteria) in this organ. As a result faster decomposition and increase the mineralization rate of its nutrient happens. Generally, the plants decomposition rate depends on the ratio of carbon to nitrogen. As this ratio is lower; the resistance of plant against the decomposer factors will be lower.

Keywords: Litter bag, C/N ratio, Decomposition rate, Prangos ferulaceae.
