Abstract: | Echinochloa crus-galli is a major weed in paddy field that reduces rice yield. The objective of the research was to study the effect of E. crus-galli ecotypes and populations on rice growth and production. The research was conducted in a green house using split plot design with three replications. The main plot consisted of three E. crusgalli ecotypes i.e ecotype from Karawang, Cikampek, and Sukabumi. E. crus-galli population as sub plot consisted of 0, 1, 2, 3, and 4 E. crus-galli per pot. The results showed that ecotype of E. crus-galli affected plant height, number of tiller, and panicle density. The competitivenes against rice of E. crus-galli ecotype Cikampek was higher than that of ecotype Sukabumi and Karawang. Population E. crus-galli affected rice growth and production. Population of E. crusgalli 4/pot decreased spikelets weight about 48.0% and filled spikelets weight about 46.2%. Interaction of ecotype and population of E. crus-galli did not affect rice growth and production. |
