Soil factors affecting the toxicity of alkali. Its severity, cause and effects upon the people. Cairo-East Bank effluent re-use study 3 - Effect of field crop irrigation with secondary treated wastewater on biological and chemical properties of soil and groundwater. El Lateef E.M.A., Hall J.E., Lawrence P.C. Soil salinization in Danubian Lowland from the standpoint of crop tolerance to soils. Boron and calcium increase Pisum sativum seed germination and seedling development under salt stress. Ph.D thesis, University of Tehran, I.R of Iran. The abundance and distribution of arbuscular mycorrhizal fungi in saline soils of the Tabriz Plain and their inoculation effects on the improvement of salt tolerance in onion and barley. ![]() Except for cultivar PP22, the adverse effect of salinity of the irrigation water on seed germination and seedling root length was higher for NaCl alone than for the salt mixture, which refers to lower salt stress in field conditions with natural salt composition. Regardless of salt composition, seed germination and seedling root length were significantly affected by the irrigation water with EC up to 8 dS/m and 4 dS/m, respectively. Statistical analysis revealed that germination and root length were significantly affected by salt composition, cultivars and salinity levels. Seed germination percentage and seedling root length growth were determined in 13 days. Thirteen salinity levels with electrical conductivity (EC) of the irrigation water ranging from 0 to 30 dS/m were applied to each cultivar in both experiments. The experiments were undertaken with irrigation water with two salt compositions (NaCl alone and mixture of MgSO4 + NaCl + Na2SO4 + CaCl2) in three replicates. The aim of this study was to determine the effect of water salinity levels and salt composition on germination and seedling root length of four sugar beet cultivars (PP22, IC2, PP36, and 7233). ![]() Sugar beet yield declines with an increase in salinity, but the sensitivity to salts varies with salt composition in water and sugar beet growth stage. Salinization occurs naturally in arid and semiarid regions where evaporation is higher than rainfall. Salinization is one of the most important factors affecting agricultural land in the world.
