Growth of Dieffenbachia amoena ‘Tropic Snow’ in Growing Media Containing Sugarcane Bagasse and Sawdust Vermicompost

Vermicompost produced from sugarcane bagasse (sbv) or sawdust(s) were substituted at a range of different concentration in soilless beddingplant container medium, as a peat: vermiculite: perlite (6:3:1), to evaluatetheir effects on the growth of dieffenbachia amoena in the greenhouse. dieffenbachiaamoena was grown in container medium pe: ve: p (6:3:1), in thatpeat substituted with 0%, 10%, 20%, 30%, 40%, 50% and 60% (by volume)sbv. the control consisted of pe: ve: p (6:3:1) alone without sbv or sv.plants were frequently treated with a nutrient solution for seven months. thegreatest growth of dieffenbachia amoena plant resulted from substitution of60% sbv or sv instead of peat in pe: ve: p (6:3:1) potting mixtures. weconcluded that vermicompost of sugarcane bagasse or sawdust was highquality substitutes for peat.
