| Abstract | ||
| A pot experiment was conducted to evaluate the effect of Cd and P levels on growth and yield components of sunflower(Helianthus annuus L.Meak). The dry weight yields of leaves , stems, and roots after 35 days from sowing and weight of seeds. Plant at harvest were reduced by cadmium application. Dry weight of stems , seed oil percentage, plant height and leaf area at harvest were not affected. Phosphorus application as superphosphate fertlizer had no significant effect on the studied growth parameters. Cadmium content in leaves of sunflower increased by cadmium application while cadmium content of seeds was not affected. DTPA-Extractable Cd in soil, and Cd content in leaves of plants were increased by adding cadmium to soil than the impurities from superphosphate fertilizer. | ||
