| Abstract | ||
| To study the allelopathic effect of Cymbopogon olivieri on germination and growth properties of two millet cultivars, an experiment was carried out in a completely randomized design (CRD) with three replications. The treatments included different levels of 0 (control), 12. 5, 25 and 50 gL-1 extract. In another experiment, carried out in the greenhouse, the treatments included four levels of soil. According to the obtained results, all studied traits of kcm7 cultivar were more affected by allelopathic effect of Cymbopogon olivieri, compared to kcm2 cultivar, and all traits (except germination velocity) showed a negative response, immediately after applying 12.5 gL-1 extract. In kcm2 cultivar, the negative response of germination percentage and germination velocity was recorded at 50gL-1 extract. In addition, the negative effect of plumule length and radicle length was recorded at 12.5 gL-1 and 25 gL-1, respectively. The results of greenhouse showed that the radicle length of both cultivars was affected by allelopathic effects of Cymbopogon olivieri. Our results clearly show that kcm2 cultivar is more resistant against the allelopathic effects of Cymbopogon olivieri compared to kcm7 cultivar. | ||
