ABSTRACT : An experiment was con ducted in a college of education laboratories to test the effect of allelopathy compound release from rice rasidues on wheat plant , and determined whether the reduction in growth of wheat crop rotation was due to toxicity of rice residues Allelopathybitic Activity effected of rice residues on wheat . Results showed that : Aqueous extracts of rice significantly reduced seed germination and seedling growth of wheat . The toxicity of the residues two weeks after residues decomposition of soil and continue for six weeks. The results suggest the toxicity effect of rice causative factor responsible of wheat growth .
