A field experiment was conducted at S.K.N. College of Agriculture, Jobner during rabi season of taking Raj 3077 wheat cultivars. The experiment was laid out in split plot design with four levels of compaction (control, 4, 8 and 12 passing of 500 kg manually driven roller) as main plot treatments, three levels of nitrogen (40, 80 and 120 kg N ha^-1) and three levels of potassium (20, 40 and 60 kg K₂O ha^-1) as sub-plot treatment. Maximum NPK content and uptake were recorded under twelve passing of 500 kg iron roller as compared to no passing. Increase in levels of nitrogen and potassium revealed increased in the NPK content and uptake of wheat crop, respectively.
