Abstract
In this study, we investigated the effects of rice husk addition to the propagation media on the root growth of blueberry cuttings. The number of surviving cuttings and weight of adventitious roots formed from the scion were highest in the medium that contained 50% rice husk. The total length of adventitious roots was highest in the medium containing 25% rice husk. There was a significant correlation between the growth of the adventitious roots of blueberry cuttings and the rice husk ratio in the propagation media. The values of the root zone parameters of blueberry cuttings were estimated to reach a maximum if the medium contains about 40% rice husk. From these results, we conclude that rice husk can be utilized as a propagation medium for blueberry cuttings.
