Assessment and monitoring of rangeland in different grazing managements seems necessary to manage rangelands. The plant functional groups can be used as appropriate responders for rangelands condition and management. Therefore, this study was performed and aimed to determine the most important traits that are influenced by rangeland variation and management. In order to this, three areas along ...

the arid zone encompasses land that has an imbalance between precipitation and losses through evaporation. globally, arid zones comprise large part of many countries in the mid-latitudes in both the northern and the southern hemispheres. both australia and iran are countries with a large arid zone. this negative water balance in the arid zone affects the type of land use in these countries. at ...

soil compaction has become a widespread problem in the world and is one of the factors involved in land degradation and declining crop yields, especially in the arid and semi-arid agriculture. the purpose of this study was to investigate the effects of subsoil compaction on morphological, physiological and agronomic aspects of wheat .the research was carried out in the experimental farms of anb...

BACKGROUND AND AIMS The timing of flowering and summer dormancy induction plays a central role in the adaptation of Mediterranean geophytes to changes in the length of the growth season along rainfall gradients. Our aim was to analyse the role of the variation in the responses of flowering and summer dormancy to vernalization, daylength and growth temperature for the adaptation of Poa bulbosa, ...

soil erosion by water is the main factor of land degradation, particularly in semi-arid regions where soil productivity is usually low and lowering soil quality can severely decrease crops yields. this study was done in an area of 900 km2 in the semi-arid agricultural region of hashtroud in northwestern iran to determine the relationship between soil productivity and soil erodibility. wheat gra...

Water plays a critical role in beef cattle production. Current methods used to estimate the blue water footprint of are largely based on generic values that do not make provision for different production systems within regions. Total cycle measurements should therefore be considered accurately assess grazing natural rangeland. The aim study was measure intake extensive Bonsmara Marikana Thornve...
