Survivability of three bamboo species (Giant Bamboo: Dendrocalamus giganteus, Machiku Bamboo: Dendrocalamus latiflorus and Spiny Bamboo: Bambusa blumeana) on different potting media

Abstract

At the Cagayan State University Gonzaga Campus, the study was carried out between July 2021 and October 2021 in a bamboo nursery-protected setting. Three species of bamboo (Giant Bamboo- Dendrocalamus giganteus, Machiku – Dendrocalamus latiflorus, and Spiny Bamboo– Bambusa blumeana) were the subject of the investigation to ascertain their survival rates as influenced by different soil media. It aimed to determine the following parameters after three months: average number of shoots, average length (cm) of shoots, average number of roots, average length (cm) of roots, and the percentage (%) of survival. The study used a Completely Randomized Design (CRD) with a single factor experiment. There are three treatments in the study which are T₁– control, soil media composed of one-part vermicompost, one-part alluvial soil and one-part Raw Rice Hull (RRH); T2-soil media composed of one-part vermicompost, one-part alluvial soil and one-part carbonized rice hull (CRH); T3- soil media composed of one-part vermicompost, one-part alluvial soil and two parts carbonized rice hull (CRH). On the percentage of survival, giant bamboo is the only species significantly affected by the soil media composed of one-part vermicompost, one-part alluvial soil and one-part carbonized rice hull (CRH). It is concluded that the combination of alluvial soil, vermicompost and Carbonized Rice Hull (1:1:1) was the best combination of media results on all variables measured. This treatment leads in all the parameters gathered followed by Treatment 3, the combination of alluvial soil, vermicompost and Carbonized Rice Hull (1:1:2). As a result of the research’s findings and conclusions, it is advised that using carbonized rice hull as part of the media will greatly improve the soil’s ability to support the growth of the three kinds of bamboo propagules.
