C.V. is coefficient of variation. OM is appreviated of O Mon, a location where rice cultivar was bred. Values in the same column followed by one or more identical letters are not statistically significant in the Duncan test. ** difference at 1% significance level. Negative values represent the stimulation of the extract on the root length of barnyardgrass.
