Abstract
A greenhouse study was conducted to determine the effect of rooting media in addition to Indole Butyric Acid hormone on root development of stem cuttings of Chromolaena ododrata. Stem cuttings of C. Odorata treated with equal quantities of the growth hormone (0.7%) were grown in 1 kgs of vermuculate, perlite, planting soil, sand, and equal mixture of all media. The set up were treated equally with water and organic manure. Control set up was made with a mixture of different rooting media without growth hormone. Data on shoot development were noted for 6weeks and root length was measured on the day of harvest. The parameters measured were analysed statistically using ANOVA. It was found out that root and shoot lengths were significant at p> 0.05 in the entire rooting media and the highest percentage development (49 and 51%) for root and stem respectively, was observed in the rooting media that had equal measure of each constituent (i.e. the mixed constituents). Germination rate among the media was 100, 70, 60, 50 and 40% for mixed, sand, planting soil and vermiculate, perlite and control respectively. Different sections of mature stem tested with Indole butyric acid hormone were not significant in their root and stem development, although basal cutting stems tend to mature faster than epical. This has proven that propagating C. odorata by stem cutting can be optimally achieved through mixture of 0.7% of Indole butyric acid in a collection of different rooting media.
