abstract one basic method of improving rangelands in a country is the use of native as well as exotic species of plants adaptable. among the but introduced species, atriplex canescens has been introduced in many rangelands, but it is important and necessary to consider it’s effects on native species. in the current study the effect of chemical competition (allelopathy) of atriplex canescens on ...

some chemical characteristics of root, shoot and litter of index species such as salsola rigida, artemisia sieberi and stipa barbata commonly used in rangeland development projects were evaluated and compared. chemical properties of soil under and between the above mentioned species were also studied. for this purpose, vegetation types of stipa barbata and artemisia sieberi - salsola rigida wer...

Information on different rangeland plants’ nutritive values during variousphonological stages is of importance for the rangelands management. This information helpsrangeland managers to choose proper grazing times to achieve higher animal performancewith no detrimental effects on the rangeland vegetations. Effects of various plant parts’phenological stages and vegetation types on reserve carboh...
