Seasonal changes in production and consumption of range species in Dehno-Kerman Rangelands
Abstract
It is impossible to planning and managing rangeland and livestock in case of no knowledge of plants production and consumption characteristics. In this research changes of seasonal production and consumption of dominant forage species evaluated during the growing period and grazing season for four years. For each species, five average plants were selected inside and outside the exclosure, and the production was harvested. Collected data were analyzed using SAS software and mean comparisons were done by Duncan’s multiple range tests. Results indicated production of these species in 2008 was very fluctuating with the most severe drought. Production in this year was about 43% of production in 2007.In terms of severity of production decline, species showed different reactions to climatic variations. Stipa barbata and Artemisia sieberi were produced in 2008, 36 and 37.2%, respectively. In other species, the production in 2008 compared to the wet year was between 13 and 41 percent. Results showed that the average production of 8 permanent species was 344.1 kg/ha and the share of grass species was high, and in the middle four years, about 40% of forage pasture was affected by Stipa barbata, Oryzopsis holciformis, Poa sinaica. The highest amount of these species was produced in April and May.70-75% of these species was used in March and April. About 40.5% of the forage was produced by Artemisia sieberi. A larger share of these species was used in livestock in August and September. Generally, the identification of important rangeland species in different months of the growing season can help to the proper and timely consumption of rangeland forage.
