in many studies, topographic factors have been considered as an important factor in establishing the vegetation in different ecosystems. so, it affects vegetation composition and diversity by influencing soil moisture, fertility and soil depth. the aim of this research was to investigate the effects of slope, elevation and geographical aspects on species growth, forage production and vegetation...

Range forage of Vicia variabilis, Astragalus spp., Medicago sativa, Prangos uloptera and Sanguisorba minor was sampled during three phenological stages from the controlled rangeland stations in Chaharmahal and Bakhtiari province, Iran. Samples were analyzed for the determination of Crude Protein (CP%), Ether Extract (EE), Crude Fiber (CF), total Ash, Neutral Detergent Fiber (NDF), Acid Detergen...

Preservation of forage crops as silage offers opportunity to avoid the high risk of rain-damaged hay in the humid south-central USA. Recent developments with baled silage or baleage make silage a less expensive option than typical chopped silage. Silage has been important in the region primarily for dairy production, but baleage has become an option for the more extensive beef cattle industry i...

In the rangelands of Iran, the lack of appropriate grazing management is one of the major problems ultimately leading to untimely and excessive grazing intensity of forage. Accordingly, most of the rangelands show a retrogression trend and poor conditions. In forage species, phenological stage is one of the most important criteria for range management. Bromus tomentellus species is an ...

for determination of grazing capacity, information of forage quality is essential which is influenced by various factors. the main objective of this research was investigation on effects of species, phenological stages, and life form on values of forage quality indices of six range species. species were two grasses (bromus tomentellus and dactylis glomerata), two forbs (ferula ovina and coronil...

this research was conducted to identify the limitative factors of forage productionsuitability in order to achieve the sustainable exploitation of natural ecosystems in aliabadwatershed in lorestan in 2013. the field measurements have been done through cutting andweighing method to estimate the forage amount, four-factor method to determine the rangecondition, trend scale to specify the orienta...
