Abstract

ABSTRACT    This research was done to study the increment of Gyrinops versteegii on lands with different levels of ground water depth, a shallow groundwater depth (45-50 cm) at A location and a deep groundwater depth (90-98 cm) at B location. This study used comparative method and purposive sampling. Variables observed were the increase in trunk diameter and free- branch heigtht of Gyrinops. The number of plant sample used was 6 (six) plants, three (3) plants for each location. The measurement of trunk diameter was done, using a measuring tape, at the base of the stem or at 30 cm from the ground. Free branch height was measured from the base of the stem up to the height of the first branch. These observations were done once a month for a year. The results showed that the growth of plants in two locations had differences in trunk diameter and free-branch height from the first month until the last month of observation. The average increments of trunk diameter and free-branch height in the B location were greater than in the A location. Keywords: increment, the ground water  level, Gyrinops versteegii

Abstract

Abstract The increasing of market demand along with high selling price of agarwood encouraged people to get more production by cutting down the agarwood-producing trees. As a result, the population of gaharuproducing trees become decrease and needs to be conserved. Conservation efforts is collateral with production continuity to anticipating market demand can started from planting and cultivating. One of them is the provision of quality seeds that supported by good planting media. This research studied the effect of media on the growth of Aquilaria malaccensis Lamk.,seedlings while the planting media were soil, husk, and compost. The method was Completely Randomized Design method consisting of 6 treatments and 5 replications. Each replication consists of 1 plant, so there are 30 experimental units. Treatment is distinguished based on volume comparison of planting media, namelytreatment 1 (P1) soil, treatment 2 (P2) compost, treatment 3 (P3) husk, treatment 4 (P4) combination of soil:compost (50%: 50%), treatment 5 (P5) combination of soil: husk (50% - 50%), and treatment 6 (P6) combination of compost: husk (50%: 50%).The variables which observed were plant height, stem diameter and number of leaves. The results showed that the treatment of planting media using compost (P2) gave significant effect on the increase in height and number of leaves of Aquilaria malaccensis Lamk.,seedlings.  Key words : Aquilaria malaccensis Lamk., seedlings, soil, compost, husk
