The effect of planting hole size and manure on vegetative growth of agarwood (Aquilaria malaccensis L.)

Agar wood (Aquilaria malaccensis L.) requires appropriate environmental conditions to support its growth. As a woody plant, agar wood requires a wider planting hole size which is able to provide the root development. The organic material such kind of manure has important role, particular to improve physical, chemical and biological of soil. The aims of the study is to obtain an interaction between planting hole size and manure on vegetative phase of agarwood. This research has been conducted on April to July 2016 at field as the Academical Business Unit Agro Techno Park, Brawijaya University, Jatikerto, Kromengan-Malang. The data was analyzed with F test at 5% level and there is a significant followed by Least Significant Different (LSD) at 5% level. This research used experimental of factorial with randomized block design which had hole size as a first factor and a goat manure as second factor. The result of this research presents that there was interaction between planting hole size and manure on the parameter number of leaves which was investigated 14 week after planting, number of branchs, and number of fallen-leaves on 5 to 14 weeks after planting. The significant effects of the planting hole size and manure reflected on the variable height of plants. Meanwhile, there are not interaction on others parameters observed.
