An experiment was conducted in the laboratories and green house of Biology Dept. Education College for Girls Univ. of Kufa for 2009 –2010 agricultural season , included the test of eleven culture media which were (non saline soil as "control" , saline soil, cotton , sand , gravel , small stone , sawdust , industrial cork , stiff paper , peat moss and rise shells ) in order to choose the best medium through growth parameter response of wheat and corn plants as ( test plants ) to study soilless culture subject by using manure aqueous extract in plants irrigation .
Results showed that, sand and sawdust media were best culture media among the different cultures in this study , due to their highest germination percentage 90% and 92% , respectively as compared with control which was 75% . Results also revealed that the highest plants growth parameters ( shoot and root length , leaf area , wet and dry weight ) were achieved from the sand media as compared with sawdust response for the same parameters . |
