Abstract: A pot culture experiment was conducted to study the effect of chemical and nano nitrogenous fertilizer on content and uptake of N, P, K by grain and straw of sorghum (Sorghum bicolor L.) crop. The investigation was carried out in CRD design three replication with seven different treatments. The treatments included T₁ = Absolute control (No fertilizer), T₂ = Nano polymer, T₃ = RDN dose of sorghum crop through chemical fertilizer, T₄ = NN_2.5-2.5 times reduction of RDN through nano fertilizer, T₅ = NN₅-5 times reduction of RDN through nano fertilizer, T₆= NN₁₀-10 times reduction of RDN through nano fertilizer, T₇ = RDN through nano fertilizer. The result reported significantly highest contents of major nutrients (N, P and K) and micronutrients (Fe, Mn, Zn and Cu) in grain and straw with nano nitrogenous fertilizer treated soils. The nano nitrogenous fertilizer also significantly increased the uptake of N, P, K, Fe, Mn, Zn and Cu by grain and straw.
