A field experiment was conducted to study the effect of different levels and methods of potassium application on yield, K uptake and forms of potassium in wheat crop at experimental field of Division of Soil Science, Sher-e-Kashmir University of Agricultural Sciences and Technology, Kashmir. The treatment consisted of 5 levels of potassium (0, 20, 40, 60 and 80 kg K2O ha(-1)) and two methods of application viz Single basal and split (1/2 basal+1/2 at tiller initiation stage). Out of various treatments, split application of potassium @ 80 kg K2O ha(-1) was found superior to single basal application in terms of grain yield (43.20 q ha(-1)) and K uptake (22.89 kg ha(-1)) by grains at harvest. However, it was at par with split application of 60 kg K2O ha(-1). All forms of potassium viz water-soluble, exchangeable, available, boiling HNO3 extractable and lattice increased with increasing levels of potassium and were found maximum (3.20, 62.80, 66.00 ppm 0.723 and 1.440% respectively) when potassium was applied @ 80 kg K2O ha(-1) in two equal splits except for lattice K which was maximum (1.440%) when potassium was applied @ 60 kg K2O ha(-1).
