Mohsen Sherafatmandrad; Gholamali Heshmati; Mohammadrahim Forouzeh; Hosein Badripour

Volume 21, Issue 3 , December 2014, , Pages 447-454

Abstract
  Measurements of production and utilization of key range plant species are of utmost important tools for making range management decisions specially for stocking rate determination. A study was conducted to examine the relationships of production and utilization of Agropyron cristatum and Stipa barbata, ...  Read More

Investigation on relationships between soil properties and vegetative types (Case Study: Dejinak-e-Khash Rangeland - Taftan Balochistan)

Rasool khatibi; Yaser Ghasemi Arian; Esfandyar Jahantab; Mohammad Haji hashemi

Volume 19, Issue 1 , June 2012, , Pages 72-81

Abstract
  Soil properties are of the effective factors in distribution of vegetation, especially in arid and semi arid regions as the effect of geology, topography and climatic factors appeare in soil properties. In this study, soil properties of rangeland vegetative types was studied in Dejinak-e-Khash in the ...  Read More

Survey of capability of remote sensing indices for enhancement of land cover in arid areas (case study: Najmabad)

Mitra Shirazi; Gholam reza Zehtabian; Hamid reza Matinfar

Volume 17, Issue 2 , September 2010, , Pages 256-275

Abstract
  Recently there is a great deal of interest in the quantitative characterization of temporal and spatial vegetation patterns with remotely sensed data for the study of earth system science. One of important methods for extracting information from satellites image is use of indices. In this study for enhancement ...  Read More

Study of quantities and quality forage yield on 36 population of tall fescue (Festuca arundinacea scherb. ) order to introduce for pasture and rangelands improvement in Ardabil province.

Aliakbar Emani; Aliashraf Jafari; Rajab Chokan; Ali Asgari; Farokh Darvish

Volume 15, Issue 4 , January 2009, , Pages 493-507

Abstract
  In order to determine the best populations for both yield and quality traits, 36 populations of tall fescue (Festuca arundinacea) were evaluated using a triple lattice design in Ardabil, Iran  during 2005-2006. The data were collected for heading date, plant height, dry matter yield and five quality ...  Read More
