Potassium concentration in leaf, stalk and grain of maize from two sources was studeid at Research Farm, NWFP Agricultural University, Peshawar. Potassium was applied in both the forms at the rate of 0, 30, 60, 90 and 120 kg K ha , alongwith a basal dose of 120 Kg N + 75 kg P2O5 ha in the form of urea and single superphosphate. Maximum potassium concentration in leaf at tasscling stage was observed due to 120 kg K ha" followed by 90 kg K ha" , though nonsignifcant among themselves but highly signifcant than control and lower doses. At tasscling stage, maximum K content was reported due to 120 Kg K ha" in the form of K2SO4. Potassium content in stalk was higher due to K2SO4 application than KCl at 120 kg ha" . Maximum K content in grain was due to 90 kg K ha" . 120 kg K ha" decreased K content than 90 kg K ha"1 but was significantly higher than control and lower doses
