One of the most important challenges of human being in recent years is water crisis and drought. So evaluating the situation of drought is very important in optimized water resource management. In current research, the data of precipitation for two future periods of 2025-2045 and 2065-2085 produced using results of 5 general circulation models of atmosphere (Csiromk3.6, Gfdlcm2, GISS-E2-R, Ipsl...
Iran is one of the world's arid regions and exposed to dust particles in the air. This is important in spatial and temporal terms as well as the affects human health. In this paper a day when due to the amount of dust particles visibility reduces to 5,000 m is considered the dusty day. In the spatial and temporal analysis of dusty days 38 synoptic stations were studied. In order to conduct data...

Drought stress stimulates the production of reactive oxygen species (ROS) in chloroplasts. ROS laed to lipid peroxidation and damage to the cell membrane. In the current study, the effect of different concentrations of silicon were examined on oxidative stress caused by drought in fennel plant. The experimental design was a split plot based on RCBD with three replications in which irrigation re...
In order to investigate the responses of promising bread wheat lines to different environmental conditions and determine of the stability of their grain yield, one experiment was done with 30 bread wheat genotypes and two commercial wheats as checks using alpha lattice design with four replications in six experimental research stations in southern warm and dry climatical zones in Iran (Ahvaz, ...
Water scarcity, its necessity in food production, and environmental protection in the world have forced human beings to seek new water sources. Nowadays, application of unconventional water resources (wastewater) has been proposed in countries facing the crisis of water resources shortage; however, a few studies have dealt with this issue. The present study has evaluated the changes in the elem...
