Abstract: A field experiment was conducted in calcareous soil (medium in available K) in split-plot design with two rice varieties (Inbred and Hybrid) in main plot and six combinations of potassium management [control, NP(-K); NP+K(100 % basal); NP+K(50% basal + 50% tillering); NP+K(50% basal + 50% panicle) and NP+K(50% basal + 25% tillering + 25% panicle)] in sub-plot at Experimental Farm, RPCAU, Pusa, Samastipur, during kharif – 2017. Post-harvest surface soil samples were analyzed for different forms of potassium (available K, water soluble K, exchangeable K, non-exchangeable K, lattice Kand total K). Water soluble potassium was significantly higher in treatments receiving potassium in split application than treatment receiving total potassium as basal. All the fraction of potassium was highest in treatment receiving potassium in split.
