Effect of Potassium Sulphate on the Growth and Uptake of Nutrients in Wheat (Triticum aestivum L.) Under Salt Stressed Conditions

Abida Kausar, Munazza Gull

Abstract


Wheat is cultivated throughout the world to meet the needs of food and feed and industrial raw material in several countries. The salinity has been confirmed as main constrain of crop production and major threat to the agriculture. There is a need to increase the wheat production in marginalized soils. Different strategies have been adopted to increase the crop productivity in the world. During the current study effect of potassium sulphate was investigated for crop production in the salt stressed areas. Different application rate of K2SO4 (i. e., 50, 100, 150, 200 mM) under 150mM NaCl stress were used. It has been observed that the application of K2SO4 has increased the biomass production irrespective of the rate of application. The application of 200 mMK2SO4 proved to be the best to increase the maximum biomass in saline environment. It was also observed that the use of fertilizer has also increased the uptake of essential nutrients like potassium, calcium, magnesium and phosphorus in saline soils.
