Interference of allelopathic rice cultivars on barnyardgrass under different water irrigation and rice plant density

Abstract

Abstract: Pot culture experiments were conducted to examine the effects of water irrigation and rice plant density on the interference of allelopathic rice on barnyardgrass (Echinochloa crus-galli).The results showed that under water irrigations,allelopathic rice cultivars Xiayitiao,Gumei 2 and Zhong 156 significantly reduced the plant height of barnyardgrass than non-allelopathic rice cultivars Xiushui 63 and Chunjiang 11.Barnyardgrass plants grew shorter as rice plant density increased.Allelopathic rice cultivars Jizaoxian and Gumei 2 interfered with barnyardgrass,even at their densities as low as 4 plants per pot,and the interference reduced plant height of barnyardgrass significantly compared with the non-rice control.Allelopathic rice cultivars Xiayitiao,Jizaoxian,PI312777,TN1,Gumei 2 and Zhong 156 at 32 rice plants per pot inhibited the growth of barnyardgrass significantly than Chunjiang 11.
