. In order to study the variation for seed yield and its components, 200 accessions of alfalfa (Medicago sativa L.) were sown as drilled plots, using alpha designs/unreplicated with two repeated entries with in all of 10 blocks under dry land farming system in Kabodarahang Research Station, Hamadan, Iran, during 2010 to 2011. Data were […]
This study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. The study was carried out in steppe rangelands of Saveh, Markazi province, Iran. Four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. To study […]
Poa genus has a high value for grazing and forage conservation concerning the livestock. In order to study the impacts of cold temperature and Growing Degree Days (GDD) on seedling morphological trait and phonological development of two species involving Poa pratensis and Poa trivialis, this research was conducted in laboratory and greenhouse and outdoor of […]
Secale montanum is one of the important perennial grasses growing naturally in arid to semiarid pastures and rangelands, with a typical Mediterranean climate, in northern and western Iran at altitudes of 800-2900 m. In this paper, seed storage protein profiles of nine wild populations of S. montanum from different regions of Iran and their phenotypically […]
Grass pea (Lathyrus sativus L.) has a high potential for forage production in both rangelands and cultivated rainfed areas of Iran. It is well adapted to semi-arid areas of west and north of country where annual rainfall is 250–350 mm. To study the seed and Dry Matter (DM) yield and agronomic traits, six genotypes of […]
Medicago spp. is the most important forage crop in many regions of the world. Annual medics have distinct advantages over perennial Medicago. These species have faster growth rate in cultivation year, higher crude protein percentage, tolerance to pests and more vigorous seedlings. Morphological and physical aspects of pod and seeds of annual medics play a […]
The objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (DM yield) and 5 quality traits such as Dry Matter Digestibility (DMD%), Water Soluble Carbohydrates (WSC%), Crude Protein (CP%), Acid Detergent Fibre (ADF%) and total ash in tall wheatgrass […]
This research aims to evaluate the effects of seed scarification on five perennial Astragalus species including A. effusus, A. vegetus, A. subsecundus, A. brevidens and A. cyclophyllon in the field conditions. Seeds were sown after scarification with sandpaper by hand in the field of Homand Absard Rangeland Research Station, Damavand, Iran in autumn in 2008. […]
Strong benefits of species diversity have been demonstrated in mixed cropping on rangelands. In order to determine the best composition of mixed cropping of alfalfa (Medicago sativa) with three cool season grass species (Agropyron elongatum, Agropyron desertorum and Festuca arundinacea), on yield and quality traits, an experiment was conducted during two years (2009 and 2010) […]
This study was carried out to evaluate drought stress tolerance in Thymus kotschyanus accessions using a factorial experiment based on a Completely Randomized Design (CRD) with 5 replications during 2013-2014 in Qom, Iran. The first factor was the accession with 17 levels and the second factor was drought stress with three levels of irrigation including […]
