Copper (Cu) pollution in agricultural soils is considered as a serious health risk due to its accumulation in plants. Thus, there is an urgent need to optimize nutrient application for higher yield with lower Cu uptake to ensure food security. A pot experiment was conducted to determine the effects of single and/or combined application of different levels (0 and 80 kg ha⁻¹) of phosphorus (P) and gibberellic acid (0 and 100 mg L⁻¹) on Cu accumulation, morpho-physiological and antioxidative defence attributes of jute (Corchorus capsularis L.) exposed to severe Cu stress (0, 200 and 400 mg kg⁻¹). Results revealed that C. capsularis tolerated up to 200 mg kg⁻¹ Cu concentration without a significant (P < 0.05) decrease in biomass, plant height and root length but further increase in Cu concentration from 400 mg kg⁻¹ exhibited a significant reduction in plant height, root length, stem fresh weight, stem dry weight, plant …
