Effects of manure and zeolite on heavy metal (cadmium) adsorption and chlorophyll content of mungbean (Vigna radiate L.)

A greenhouse experiment was conducted to study the Effects of manure and zeolite on heavy metal (cadmium) adsorption and chlorophyll content of mungbean (Vigna radiate L.) an experiment in Factorial based on randomized complete block design with three replications in 2013 at varamin were performed. Treatments were: first factor manure in three levels including 0, 20 and 40 kg/ha and the second factor zeolite in three levels including 0, 10 and 20 kg/ha. Results showed a significant effect of manure and zeolite on stems Cd content, roots Cd content, grain Cd content, absorption factor of Cd, chlorophyll content a, chlorophyll b, total chlorophyll, had a significant effect, but the effect of manure and zeolite on transmission factor was not significant. Interaction between manure and zeolite on chlorophyll content a, total chlorophyll was significant. The maximum and minimum total chlorophyll to 20 ton/ha of zeolite 40 ton/ha of manure and control treatments with 1.153 and 0.852 mg.gfw-1 respectively. Generally, application of manure and zeolite on chlorophyll content and also reduce the absorption of cadmium was significant.
