Abstract EN

Several experiment were conducted in a college of education laboratories Univercity of Kufa to test responses of wheat plant (Triticum aestivum L.) to Allelopathic phytoexcudates of rice plant (Oryza sativa L.) .

Result showed that : 1- Aqueous extract of rice (IPA 1) causation significantly inhibition effected that the aqueous extract of rice (Anber 33) .

2- The rice plant soils significantly inhibition effected in seeds germination and seedling growth of wheat and rice .

3- There are differences between wheat plant and rice plant tolerance ability to allelopathic effected of rice (Anber 33 and Apa 1) in all stage of growth .

The autotoxicity between (anber 33) and (Apa 1) appeared very clear-cut but that (Apa 1) significantly effected in Autotoxicity .

4- The rice residues added in (1%) ratio causation significantly reduced in most of treatment ، specially in mature and flowering .

5- The rice plant (Anber 33) more resistance from variety (IPA1) .and the wheat ( maxipak) more resistance from variety ( saberpic )
