Wormwood sagebrush (Artemisia sieberi Besser) is one of the most widely distributed shrub species in Iran and Turkistan steppes, its establishment on dry lands has generally been proven difficult because of low seedling vigor, inability to compete with herbaceous species, poor seed quality, and altered edaphic conditions. In order to evaluation of planting methods and […]
The objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass Agropyron elongatum. A split plot design was conducted using a complete randomized block with two replications in Lorestan (Borujerd), Iran during 2007-2008. The genotypes were cut in five maturity stages as […]

The rangelands, as one of the largest dynamic biomes in the world, have very capabilities. Regulation of greenhouse gases in the Earth’s atmosphere, particularly carbon dioxide as the main greenhouse gases, is one of these cases. The attention to rangeland, as cheep and reachable resources to sequestrate the carbon dioxide, increases after the Industrial Revolution. […]
Plant Diversity conservation is a main objective in rangeland management. Plant diversity is a suitable index for showing the changes of vegetation in rangelands and has a high correlation with ecosystem parameters. Therefore, using this index it is possible to find the changes and manage the ecosystem correctly. The current research was performed to determine […]
Main perennial rivers of Gujarat, Tapi, Narmada, Mahi and Sabarmati are meeting Arabian Sea in Gulf of Khambhat. The out flow of Mahi River into the sea is decreased due to construction of dams like Bajaj Sagar, Kadana, Panam and Wanakbori weir.
