Effect of irrigation water salinity levels on growth indicators of wheat (Triticum aestivum L.)

This experiment was conducted in the lathhouse of Basra during the 2021-2020 using plastic pots with a capacity of 5 kg. Three levels of salinity of irrigation water were 1, 3 and 5 dS.m⁻¹. The use of irrigation water with increasing levels of saline led to decrease in the average of production of dry weight of the vegetative part. When salinity levels rise (1 to 3 and 5dS.m⁻¹), there was decrease in calcium,magnesium and potassium in the plant vegetative part tissues and an increase in sodium and chloride content. The increase in the salinity of the irrigation water decreased the absorbed amount of calcium, magnesium, sodium and potassium and increased chloride absorbed.
