Abstract :
Cadmium is a heavy metal pollutant in the environment and is classified from various sources such as fertilizers into the soil and enter the food chain of human poisoning causes oxidative stress in plants. This study aims to improve soil contaminated with heavy metals such as cadmium on plant growth parameters were prko.To this end the experiment in order to investigate the effect of humic acid on absorption of cadmium in the plant and the fungus Trichoderma. Factorial experiment in a randomized complete block design with 3 factors and 4 replications was designed. The results of analysis of variance showed that the soil itself represents a significant effect on all traits are while an increase in concentration of 60 milligrams per kilogram of soil cadmium than 30 milligrams per kilogram of rose gathering and the lowest decrease in absorption at 30 mg per kg of humic acid and Trichoderma observed and most treatments lack of absorption in the treatments used to taking them and the lowest decrease in absorption at 30 mg per kg of humic acid and Trichoderma observed and most treatments lack of absorption in the treatments used to taking them.
