introduction: fao aquacrop model (raes et al., 2009a; steduto et al., 2009) is a user-friendly and practitioner oriented type of model, because it maintains an optimal balance between accuracy, robustness, and simplicity; and it requires a relatively small number of model input parameters. the fao aquacrop model predicts crop productivity, water requirement, and water use efficiency under water...

abstract- olive (olea europaea l.) is one of the most valuable and widespread fruit trees in iran. salt stress-induced changes in membrane stability, photosynthesis and antioxidant enzyme activity were examined on four olive cultivars (dakal, shiraz, zard and amigdalifolia) by emphasizing the correlation between measured parameters and ion (k+, na+) accumulation. plants were subjected to four s...

the plant promoting bacteria as biological fertilizers play an important role in increasing productivity and improving plant growth in stress condition. in order to evaluate the ability of plant promoting bacteria rhizobacteria on germination and growth of corn under salinity conditions, a pot experiment was conducted in factorial based on randomized complete block design with three replication...

abstract plants are exposed to stressful environmental conditions in the process of growth and development. one of the most important stresses is the salt stress which can limit the plant’s growth and yield. plants symbiosis with arbuscular mycorrhizal fungi in salt conditions can affect the plant’s yield as well as growth parameters. the plant’s growth in salt stressful conditions might be red...

a hydroponic experiment was conducted to evaluate the effects of salt stress on safflower genotypes under greenhouse conditions. the experiment was arranged as a factorial one based upon a completely randomized design with three replications. five safflower genotypes (arak2811, nebraska10, sod25, ca116, and ca128), and four salinity treatments (0, 0.3, 0.5, and 0.7 percent of nacl) were employe...

In Tunisia, more precisely in semi-arid and arid areas, drought accentuated by the superficial evaporation of water leads to a gradual increase salinity, which is limiting factor crop production. these highly salty ecosystems, some plants grow naturally; however, various species show different levels tolerance salinity during their development. The germination seeds most sensitive stage this ab...

in order to study the effect of irrigation water salinity on quality and quantity of sugar beet (beta vulgaris) at four growth stages, an experiment was conducted in rudasht salinity and drainage research center from 2004-2006. in this experiment, 11 different water salinity treatments and three sugar beet cultivars (ic, 7233 & 7233-p29*msc2) were considered using split plot design based on ran...
