| Abstract This study aims to investigate the effect of soil pollution with lead, cadmium and their interference in the levels of (0, 125, 250) ppm and (0, 2.5, 5.0) ppm respectively on growth, yield and some physiological changes in the plant (Carthamus tinctorius L.) under nitrogen nutrition condition. The results of the study showed that the addition of lead and cadmium incrementally to the soil separately or jointly leads to decrease in the growth, yield, seed production and its content of protein, carbohydrate and oil .while the addition of nitrogen to the soil lead to increase the growth, yield and increased the tolerance of plants to the lead and cadmium elements when compared with the plants growing in soil containing lead and cadmium but with the absence of nitrogen nutrition. | ||
