Copper (Cu) contamination in soils is becoming a serious problem. Therefore, an experiment in plastic pots was carried out to investigate interactive influence of rice straw BC (BC 0 :0, BC 1 :5, and BC 2 :10% w/w) and nitrogen fertilizer (N 0 :0, N 1 :140, N 2 :280, and N 3 :420 kg ha−1 ) on plant growth, Cu mobility and phytoavailability to  Boehmeria nivea  in Cu polluted soil. Results revealed that BC × N fertilizer had significantly ( p  ≤ 0.05) increased the growth of  B. nivea  in terms of biomass, height of plant, diameter of stem and number of leaves. Furthermore, BC × N fertilizer resulted in significant changes in pH, electrical conductivity and cation exchange capacity of soil after harvesting in comparison with control. However, the influence of BC × N fertilizer on soil extractable Cu and Cu uptake by plant varied with levels of N fertilizer. The BC 2 N 1  treatment significantly increased the shoot biomass of  B. nivea  by 635% (fresh biomass) and 452% (dry biomass), but reduced Cu contents in roots, stems and leaves i.e., 52, 23 and 34 mg kg−1 , respectively. Thereby, high dose of BC along with low N fertilizer could be considered as an efficient soil amendment combination for Cu stabilization and higher biomass production of  B. nivea  in highly Cu contaminated soil.
