Ensuring the sustainability of cultivated soils is an ever-increasing priority for producers in the Lower Mississippi River Valley (LMRV). As groundwater sources become depleted and environmental regulations become more strict, producers will look to alternative management practices that will ensure the sustainability and cost-effectiveness of their production systems. This study was conducted ...

in determining how a plant responds to moisture deficit stress. Moisture deficits can depress cotton (Gossypium hirsutum L.) lint Although there has been considerable research docuyield in all cotton production regions. However, most cotton physiomenting the growth and physiological response of cotton logical drought stress research has been conducted in arid production to moisture deficit stre...

Research on ecosystem and societal response to global environmental change typically considers the effects of shifts in mean climate conditions. There is, however, some evidence of ongoing changes also in the variance of hydrologic and climate fluctuations. A relatively high interannual variability is a distinctive feature of the hydrologic regime of dryland regions, particularly at the desert ...

Due to increasing water and growing demand for food a more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving condition...

in order to study physiological characteristics of rainfed bread wheat genotypes, an experiment was conducted with 20 genotypes in a randomized complete block design with 4 replications under rainfed and supplementary irrigation conditions. this experiment was carried out at the dryland agricultural research institute (dari) in maragheh during 2007-2008. to determine growth indices, sampling wa...

wheat grain yield is adversely affected by post-anthesis drought stress conditions in most wheat growing areas of iran. to evaluate the effect of late drought stress on wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of collage of agriculture, shiraz university during 2009-2010 growing season. ir...
