Genetic variations within the species of Agropyron desertorum and 2 varieties of A. cristatum subsp. pectinatum var. imbricatum and A. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). An experiment was conducted in Research Institute of Forests and Rangelands (2012-2013) using a completely […]
Accurate knowledge of spatial distribution of soil physical and chemical properties is needed for suitable management and proper use of rangelands in Masileh plain, Qom, Iran. In present study, for the spatial modeling of chemical and physical parameters such as sodium (Na), calcium (Ca), soluble potassium (K), magnesium (Mg), Electrical Conductivity (EC), Saturation Percentage (SP%), […]
One of the main objectives of ecosystem management is to preserve the species diversity. Many researchers regard higher species diversity as the stability of ecological systems. The aim of this study is to investigate the stability and relationships between topographical factors with diversity indices in Ghorkhud mountainous rangeland in northern Khorasan province, Iran. For data […]
Soil salinity affects a large part of the region in Iran. Salinity covers 12.5% of total area of the country. Priming of seeds in sodium chloride and water (hydro-priming) has been reported to be a simple technique for enhancing the seedling establishment and germination performance in the seeds of many crops and small seeded grasses […]
Rangelands are the main sources of forage for livestock feeding by local people. Beside forage production, rangeland ecosystems provide many other goods and services such as medicinal plants, recreation, soil and water conservation, wildlife habitat, fishing, hunting, hiking, etc. Nevertheless, there are no much information about the way that local communities think about the rangelands […]
Knowledge of physiological and environmental factors is important for forage grass production. Festuca ovina is a grass species adapted to Azerbaijan region climate, Iran. This species is a valuable source for forage production and soil conservation. Nitrogen (N), Phosphorus (P) and Potassium (K) are three most important plant nutrients. The aims of present study were […]
The overgrazing and excessive utilization of rangelands has caused vegetation and soil degradation in many rangelands. In the rangeland management, the soil and vegetation elements, environmental factors and livestock should be considered as decision making agents. Various methods are applicable for the rangeland restoration as contour furrows and mortar stone dam. In order to evaluate […]
Tragacanth Gum is one of the most important medicinal and industrial products of rangelands and is obtained from the incision of gum tragacanth-producing Astragalus including Astragalus keyserlingii. The conservation of Astragalus species in rangelands has a special place in terms of economic profit and soil conservation. The increase in price of gum tragacanth in recent […]
Dr. Victor R. Squires of Adelaide, Australia received the Outstanding Achievement Award for Stewardship at the Society for Range Management’s 68th Annual Meeting held in Sacramento, California earlier this month. The Outstanding Achievement Award is presented by the Society for Range Management for outstanding achievement to members and other qualified individuals and groups working with […]
