Study of seasonal changes in production and consumption of range plant Artemisia sieberi (Dehno- Kerman Province)
Abstract
Artemisia sieberi is one of the appropriate forage plants to provide forage for livestock and it is suitable for soil conservation purposes in the steppe rangelands such as rangelands in Dehno (Kerman, Iran). Production and consumption of forage of Artemisia sieberi were carried out for four years. For this purpose, the residual forage after grazing was taken at intervals of one month. The consumption was determined by the subtraction of the residual forage from the production within the enclosed area. Finally, the impact of the years of study and months of grazing on the production and consumption of species in the region was analyzed using SAS software. The results showed that the year (2007) and the year (2008) has the highest and the lowest production, respectively, so that the average of 41.5% pasture forage was produced by species of Artemisia sieberi in the four years. On average, 30% of the production was used by livestock during the grazing season. The Years 2007 and 2008 have the highest and the lowest forage consumption, respectively. The highest production of Artemisia sieberi was in late September. Consumption of this species by livestock during the months of April and May is low because of high essence of this plant and the presence of the other desirable species. The area is grazing heavily by livestock in September. With regard to the consumption of this species by livestock and high production of Artemisia sieberi, it is a good source of forage in steppe rangeland. (248 words)
