Yazd province has the first place of sweet Asafetida (Ferula assa-foetida) resin export, proper management of this valuable species natural habitats is very important to the exporters. This study was performed to investigate resin yield at different cutting sequences, 1 to 13 cuts. The soil characteristics was also investigated in Taft rangelands of Yazd province. Samples were taken from Nasrabad and Oghabkooh-Fazeabad regions which are the main habitats of sweet Asafetida in Yazd province. Sampling method was completely randomized. So, 20 plants with the same ages (5-6) were selected in each regions for the test. Soil samples were taken at depths of 0-30 cm in each site. Data were analysed in SPSS16 and Excel environments. The results showed that Asafetida plants had have produced more resin in 6, 7, 8, 11, 12 and 13 cutting stages in Nasrabad habitat. The total amount of gum and Keshteh (pieces of cutting root with gum) with 28.05 and 69.09 gr. respectively, had a significant increase in Nasabad compare to Oghabkooh habitat (21.01 and 55.94 gr, respectively) (p<0.01). The results indicated that resin yield in 6 and 7 cuts and Keshteh in 8 and 9 cuts had significant increase in different cutting levels for both habitats (p<0.01). Investigation of soil parameters showed a significant increase of silt, clay, lime, organic matter percentages, potassium (p<0.01) and phosphorous (p<0.05) in Nasrabad habitat compared to Oghabkooh area; while, sand percentage decreased significantly in Nasrabad region (p<0.01). According to the results, nine times cuts is suggested for the sustainable use of Taft rangelands. Nasrabad rangeland plants could be use (because of the better resin yield) for seed collection to develop sweet asafetida and increase the region's economic potential.
