Abstract: The field experiment was conducted at the Research cum Instructional Farm, IGKV, Raipur (C.G.) during kharif season of 2015. The experiment was laid out in split-plot design with three replications. The treatment composed of three nitrogen levels N₁ (100 kg N ha^-1), N₂ (125 kg N ha^-1) and N₃ (150 kg N ha^-1) assigned to main plot and six nitrogen splitting S₁–3 Splits (20:50:30 at 0, 30, 60 DAS), S₂–3 Splits (20:50:30 at 10-12, 30, 60 DAS), S₃–4 Splits (20:25:25:30 at 0, 20, 40, 60 DAS), S₄–4 Splits (20:25:25:30 at 10-12, 20, 40, 60 DAS), S₅–5 Splits (20:20:20:30:10 at 0, 20, 40, 60, DAS & FL) and S₆–5 Splits (20:20:20:30:10 at 10-12, 20, 40, 60, DAS & FL) were allotted to sub-plot. The crop was fertilized with 60 kg P₂O₅ and 40 kg K₂O ha^-1. Among nitrogen levels and splitting, N₃ (150 kg N ha^-1) with S₆–5 Splits (20:20:20:30:10 at 10-12, 20, 40, 60, DAS & FL), recorded the maximum nitrogen, phosphorus, potassium uptake kg ha^-1 and soil available nitrogen but lower in soil available phosphorus and potassium.
