Effect of individual and combined application of IAA and compost on nutrient uptake by plant A) Nitrogen (N; g kg^− 1, B) Phosphorous (P; g kg^− 1), C) Magnesium (Mg; g kg^− 1), D) Potassium (K; g kg^− 1) and E) Calcium (Ca; g kg^− 1) under Ni stress. Bars displaying same alphabets are statistically non-significant at P < 0.05
