Abstract
Abstract : This experiment was applied in the canopy of the college of Agriculture / university of Al-Qadisiay . In the field experiment, wheat and bean plants were cultured in the pots with three replicates for each plant. After two months from germination the rhizosphere was taken for those two plants . In the laboratory experiment the rhizosphere soil for every plant were treated with maize and cow residues as organic resources were added 2 grams to the soils for every organic resources except which the controls using three replicate for every treatment . The treatments were incubated for 30 days and in this period the CO2 releases was estimated in(1,2,4,8,19,30) days from incubation and in the end of this period the bacteria and fungi numbers were calculated in the rhizosphere . The results showed that CO2 released was increased with increasing time of incubation for both plants . Also the results showed that the cow residue was the highest in the CO2 released compere to the maize residue and control for both plants . The results showed increasing in the bacteria and fungi numbers as well with cow residue treatment compare to the maize residue and control treatments . Bean plant was highest than the wheat plant in CO2 released amount and the bacteria and fungi numbers
