An experiment was conducted to study the forage yield and qualitative traits of different cultivars of Sudan grass with different days of harvest. Five improved Sudan grass cultivars (DRLME, Mezrut, Wichello, Michello and Aden) and three harvest schedules (40, 50 and 60 day’s interval) were combined and used for the study. Randomized complete block design […]
The experiment was conducted in the 2018 cropping season with the objective of evaluating the effects of harvesting stage and seed rate on agronomic performance and quality traits of Rhodes grass (Chloris gayana K.) grown in northwestern Ethiopia under rain-fed conditions. A factorial experiment was conducted using two factors of main factor harvesting stages in […]
Measurement of Technical Efficiency (TE) provides useful information on the competitiveness of Rangeland Unit (RU) and potential to improve productivity, with the existing resources. So, the purpose of this study was to evaluate the technical efficiency of Traditional Livestock Husbandry (TLH) and determine the main factors influencing it via management variables of Range Management Plans […]
TThe Leguminosae family plays a significant role in rangeland ecosystems with biological nitrogen fixation for soil fertility. The grasses significantly increase rangeland production and sustainability. Legume-Grass Ratio (LGR) is an indicator of soil fertility. This study was aimed to investigate the LGR and some soil properties in four vegetation types (Stipa arabica Trin.-Medicago sativa L., […]
Vegetation is an important component of terrestrial ecosystems whose changes are controlled by climate changes and human activities. In order to detection the climate changes impact on vegetation dynamics of Kermanshah province, Iran, this study was conducted using multi-time images of NDVI and EVI regarded as vegetation indices taken by Modis sensors. Also, the trend […]
Wildfires annually occur as a threatening factor in natural resources at a large scale. This study was conducted with the aim of determining the effects of fire on the structural and functional characteristics of vegetation in the Kaboudeh range site, Kermanshah province, Iran during three years (2018-2020). An unburned range (control) was selected near the […]
The basis of many plant studies is the identification of plant species because identifying plant populations in every region is the pivotal pillar of plants conservation. Furthermore, study of the stages of plant growth cycle is one of the ways to determine growth details of any given plant. The current research aimed to investigate the […]
Abstract. Nowadays, in many rangelands, due to over grazing, and problems that some plants have in germination, the rate of forage production is greatly reduced. So to take advantages of the benefits of such plants, it is necessary to identify and remove barriers of germination and establishment of suitable plants. A study was carried out […]
In order to investigate the effect of contour furrow on the vegetation and soil characteristics, a study was conducted at Bolbol rangelands, Ashkazar, Yazd Province, Iran in 2020. The implementation of contour furrow was done previously at the rangeland in the area of 100 ha in 2006. Data were collected at both contour furrow site […]
