Mehrgerd region of Semirom county has faced the water shortage for several years. The emergence of drought has led to a decline in water resources in recent years; and there are various reasons for climate change and increased consumption in order to reduce water resources. The present study aimed to investigate the process of temperature and precipitation variations and its possible effects on...

Understanding the variability of pedological properties as well as the soil quality attributes on different landscape positions in hummocky terrains would result in a better land management in such areas. Despite the importance of such studies, no research has been couducted on the landscape-scale variability of soil quality indices in Iran and most researchers have so far focussed on pedologic...

In order to determine the effect of weeds interference and nitrogen on the sugar beet growth and yield, a field study was performed in the 2010 growing season as a split plot design based on RCBD with three replications in Hana region (Semirom, Esfahan). Treatments were four levels of nitrogen from urea source as the main factor (0, 70, 150 and 210 kg ha-1) and weed interference at five levels ...

Evaluating the possible relationships between vegetation and environmental characteristics can assist managers to identify effective factors influencing plants establishment and to characterize various vegetation communities. This study was aimed to evaluate the effects of long term grazing exclusion ( more than 33 years) and the controlled grazing system (resting – rotation grazing system) on ...
