this study investigates the relationship between litter quality and aerial parts of plant on c, n, k, p and c/n ratio of soil in four rangeland species including agropyron intermedium, bromus tomentellus, eurotia ceratoides and kochia prostrata. after recognizing the sites of these species in hamand absard located in 65 km of northern tehran, at the end of growing season, samples of litter, aer...

Forage kochia (Kochia prostrata ssp. virescens 'Immigrant' is native to the arid and semiarid regions of central Eurasia. It was introduced into the United States in 1966 as PI 314929 and released as a perennial forage shrub in 1984. Kochia americana is a perennial native to the United States, whereas Kochia scorparia is an introduced annual species that became a weed. To assess both the breedi...

Extending grazing into the winter, as opposed to feeding of harvested forages, can increase the sustainability of ranching in the western US. This study was conducted to determine the economic value of grazing stockpiled forage kochia (Kochia prostrata [L.] Scrad.) and crested wheatgrass (Agropyron desertorum [Fisch. Ex Link] Schultes) during the fall and winter. Changes in cow body weight, bod...

Methods. An given adaptive capabilities, including field germination seeds, response to drought, yield leafless Calligonum aphyllum, Eurotia ceratoides, and Kochia prostrata...

Broom snakeweed (snakeweed) is an aggressive native range-weed found throughout arid and semiarid areas of the western United States, that increases following disturbances such as overgrazing, drought, or wildfire. Ecologically based strategies that include controlling snakeweed and reestablishing desirable herbaceous species are needed to restore productivity and diversity to invaded areas. Th...
