A glasshouse study was conducted to measure the effects of salinity and drought stresses on growth and chemical and biochemical composition of 4 onion cultivars. The cultivars were Dessex, Texas Early Grano (Texas), Dehydrator, and PX492. Salinity treatments included control, 45mM NaCl, 45mM NaCl + 5mM CaCl2 and drought treatments were control (maintaining soil moisture at field capacity) and...

A pot experiment was conducted to evaluate the effect of salinity on growth and heavy metal uptake by maize (Zea mays) plant. The results study show that NaCl NaCl+CaCl2 treatments decreased plant (plant height, shoot weight root weight) significantly. proportion viable roots fresh declined with time. In contrast, enhanced length. increased accumulation Cd, Zn Cu in considerably both root.

Use of saline water for irrigation has shown considerable promise. However, its effect on the solubility and bioavailability of native soil nutrients is not well understood. This study was conducted to evaluate the effects of salinity on the behavior of zinc(Zn) in calcareous soils. The soil samples with different physiochemical properties were collected from four locations in Khorasan province...

soil salinity induces a stressful environment for soil micro-organisms and reduces their number and activity. the objective of this research is investigating the effect of different levels of salinity on some of soil biological indicators and also assessing the effect of two types of halotolerant rhizospheric bacteria on the value of these indexes in soil. 35 strains were isolated from saline r...

In dessert ecosystem, evaluation of range species tolerance to salinity stress is more and more appreciable for saline rangelands reclamation and forage production. The principal goal of this investigation is the effects salinity stress on production and tillering of Aeluropus lagopoides, Aeluropus littoralis, Puccinellia distans. The experiment was carried out In a completely randomized design...
