| Abstract | This research was aimed to explore the allelopathic activity of itchgrass (Rottboellia cochinchinensis) in the soil which can inhibit seed germination and plant growth. The experiments were carried out at the Department of Agronomy, 2007 - December, 2008. The allelopathic effects of soil from itchgrass- infested areas compared to itchgrass- uninfested areas were observed on growth of tested plants including Bidens pilosa, Mimosa pudica, Ageratum conyzoides, Echinochloa crus-galli, Oryza sativa cv. RD 6 and Lactuca sativa cv. OP. The results showed that root length of all tested plants grown in soil from itchgrass-infested areas was reduced compared to itchgrass-uninfested areas. The allelopathic effects from soil by growing itchgrass were tested with plants including Bidens pilosa, Echinochloa crus-galli, Lactuca sativa cv. OP and Oryza sativa cv. RD 6. Allelopathic itchgrass- infested soil inhibited seed germination and growth of some tested plants. Allelopathic itchgrass inhibited seed germination and growth of some tested plants better at 1 cm distance than 3 and 5 cm from the itchgrass. These results suggested that allelopathic activity of itchgrass in the soil can inhibit seed germination and growth of tested plants. |
