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 mM K₂SO₄ 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.
