S.M. Mehdi, A.M.Ranjha, M.Sarfraz and G.Hassan

Abstract

The number of productive tillers plant-1, grain and straw yields in wheat were increased significantly by increasing K application except grain yield in the Wazirabad and the Sultanpur soil series and straw in the Kotli series which remained non-significant. K concentration in grain was improved by 100 mg K kg -1 except in the Sultanpur and Shahdara series where it increased upto 75 mg K kg-1. While in straw it was increased upto 75 mg K kg -1 rate except the kotli series where it improved upto 50 mg K kg -1. Potassium uptake by wheat crop was increased upto 50 mg K kg -1 except in the Pindorian and the Lyallpur soil series where it increased upto 75 mg K kg -1.
