The vegetation maintaining and development of rangelands and desertlands is one of the main biological techniques for combact desertification and as a rangeland management soloutions. The best species for rangeland rehabilitation is native plants that they are adapted in the ecosystem with high forage quality and positive effective in soil and environment stability the same as Salsola orientalis and Kochia prostrata plant species in the east of Golestan province. The aim of this study is investigating the production and establishment plant growth of S. orientalis and K. prostrata. For this purpose the seed generation percentage estimated in four treatments including without treatment, washing, frosting (with -17 centigrade degree), frosting (with 11 centigrade degree during 24 hours), and frosting (with 11 centigrade degree during 72 hours) in completely random design with 30 replications after seed collecting and testing seed power. Production and seed establishment of these plants was measured at three treatments including cultivation region (Kechik and Chaparghoimeh), cultivation method (pot, band and hill method with two sub-treatments of primary irrigation and soil cover), and cultivation season (spring and winter) in a completely randomized block design with 30 replications. The seed generation speed and seed power estimated at 3 blocks and 100 replications. Also, the seed generation compared between two treatments including wing and without wing at 30 pots (3 replications). The mean of the seed generation compared by Dauncan method at SPSS23. The result showed that there is a significant difference between seed power in seed generation treatments (p-value>0.05). The seed generation speed and seed power in K. prostrata is more than the other plant. There is no significant difference between seed generation of K. prostrata between wing and without wing treatments and vice versa in S. orientalis. The best method to production and establishment of K. prostrata is winter season, Kechik region and band menthod. There is no difference between seed generating at cultivate season for S. orientalis (p-value>0.05). So that’s better to cultivate S. orientalis in seed production stations. Also, that’s suggested generation power with seed purity as a base for determination of amount of needed plant seed in a hectare.
