drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

In order to determine suitable drought tolerance indices and to identify drought tolerant wheat genotypes, an experiment was conducted at the experimental field of Ardabil Agricultural Research Station in 2010-11 cropping season. Thirty wheat genotypes were evaluated in a randomized complete block design with three replications under stress as well as non-stress conditions. Drought tolerance in...

Soil amendments have been widely used in greenhouse cultivation. Cucumber, as an important summer crop, has the highest area under cultivation in the greenhouses of Iran. For this reason, in the present research, effect of applying zeolite and drought stress on cucumber growth and its fruit parameters (number, weight, length and diameter of the fruit) was investigated in a split-plots experimen...

In order to study the effects of drought stress on agronomical traits and seed yield of new hybrids of sunflower there individual experiments were conducted on nine hybrids of sunflowers under three irrigation regimes (irrigation after 60,120,180 mm evaporation from evaporation pan class A) in 2006. The experiment was a randomized complete block design with 3 replication, performed in the resea...

Coriander is an annual plant belonging to Apiaceae family that its yield is affected by drought stress. Three experiments (normal irrigation regime, sudden drought stress and gradual drought stress) were conducted according to a randomized complete block design with three replications in 2015 to introduce the most drought tolerant Iranian coriander ecotypes based on several economical traits, a...
