Pot trails was conducted during kharif 2002–03 with a view to study the effect of K on groundnut (CV GG-2) under different level of salinity. The concentration of K, Ca and Mg decreased and concentration of Na by groundnut pod and haulm increased significantly at S4 level. Application of 100 kg K2O ha−1 significantly increased the concentration of K, Ca and Mg and decreased the concentration of Na. Interaction effect of K and salinity levels were also found significant in case of concentration of K, Ca, Mg and Na by haulm and pod.
