In order to study changes of production and utilization of Salsola laricina at growth season and Grazing season, the site of Khoshkerood-e- Saveh selected which is indicator of steppe rangelands. To evaluate the vegetative and productive characteristics and forage consumption by livestock at different stages of plant phonology, this experiment was carried out during 2010-2012 years. Thus remaining amount of forage grazing was harvested until a month intervals, and consumption rate was determined by subtraction between harvested forage and fenced plot forage. Finally, in order to study the effect of harvest months on the production and consumption under investigation in the study area, data were analyzed. The results showed that production has fluctuated during different rainfall. In Years 2011 will produce more forage than the average (264 kg ha) of about 7 percent higher and in 2010 produced the lowest yield that it was 6% lower than the average. This species share in rangeland production was high and on average four years, about 50 percent of rangeland forage was produced by Salsola laricina. In average three-year, peak rangeland production was in May and has decreased in June. On average, 92 percent of production was grazed by livestock along grazing year. Greater share of rangeland forage consumed in November and drying time of plant. Salsola almost grazed in autumn and winter and other species grazed when they were green. Due to the palatable nature and quantity of such product, is a good source of forage in winter pastures.

Keywords: Steppe rangelands, Salsola laricina, Production, Utilization, Khoshkehrood Saveh.
