Abstract

The objective of the study was to increase the growth of 5 provenances albizia (Paraserianthes falcataria L. Nielsen) in the nursery. The experimental design was Split Plot Design, with 5 provenances of albizia as main plot and 3 treatment (wood vinegar application, mychorrizae application and control) as sub plot. Each sub plot consited of 45 seeds as sample,. Growth parameter observed was delta height: that is different beetween measurement at the early application (3 weeks age of seedling ) and at the last measurement (10 weeks age of seedling). The data obtained then analyzed by using analysis of variance of continued with Duncan test. The result showed that mychorrizae and wood vinegar application have significant effect on the growth of albazia seedling. The best performance was shown at wood vinegar application (height average 75,48 cm and height delta 66,62 cm), mychorrizae application (height average 66,44 cm and height delta 59,22 cm) and control (height average 58, 92 cm and height delta 52, 48 cm) respectively. Provenance differences were also significant. The best performance  were shown at provenance of Candiroto, Kediri, Ciamis, Wamena dan Subang. Height delta each provenance after 7 weeks application were 67,65 cm, 62,93 cm, 60,15 cm 53,37 cm dan 53,11 cm; while the total height at the 10 weeks age of seedling were 74,44 cm, 69,33 cm, 69,14 cm, 61,02 cm dan 60,80 cm respectively.

Abstract

The study aimed to examine the effect of number of axillary buds on different types of mulberry hybrid and their interaction on the survival rate and cutting growth. The research was conducted using Random Design of Factorial Group (RDFG). It consists of two treatment factors, i.e. four type of mulberry hybrid (M. SHA 4 x M. LUN 109, M. multicaulis x M. indica, M. australis x M. indica, M. nigra x M. indica) and four different numbers of axillary buds with 3 replications and 30 replicates for each unit experiment. The research shows that there were effect of axillary bud number, types of mulberry hybrid, and their interaction on the survival rate and growth of stem cutting of mulberry hybrid. The number of axillary bud for the best growth of stem cutting of mulberry hibrid for the best sprout length of cutting and the highest survival percentage (81, 668%) was the 3 axillary buds, while the 4 buds was the best according to the rank of whole parameter. The best cutting type of mulberry hybrid according to the rank of whole parameter was M. australis x M. indica. Interaction beetwen mulberry hybrid and the best sprout number according to the rank of whole parameter was M. australis x M. indica with 4 sprout number.

Abstract

The aim of the experiment was to investigate to success rate of shoot cuttings on by different media and the height of hedging of Eucalyptus pellita F. Muell seedlings. The experiment was arranged in completely randomized design with two factors. The first factor was media compound, consists of 3 levels: sand, coconut husk and mixture of sand +coconut husk (1:1). The second factor was the height of hedging, consist of 4 levels : 5 cm, 10 cm, 15 cm, and 20 cm above the ground. The result showed that the effect the treatment was  significantly affected the success rate of the shoot cuttings. The cuttings from seedlings, which hedged at 15 cm above ground showed the best result. The media that gave the best rooting success was sand river. The average of rooting percentage was 15 - 95%, shoot length was 0,45 cm - 6,29 cm, shoot dry weight was 0,005 g - 0,049 g and volume of root was 0,020 ml - 0,123 ml.

Abstract

This study aimed to identity characteristic and variation of A. Mangium wood physical properties in different planting spacings and axial-radial position. Materials used were 8 years old Amangium wood from Subanjeriji, Palembang, South Sumatera with three spacings: 2 m x  3 m, 2 m x 4 m and 3 m x 3 m. Three sample trees in diameter of 21 cm from each planting spacing were taken by randomly. Specimens in each tree were taken in 3 axial position (bottom, middle and top of trunk), and 3 radial position (near pith, middle and near bark). Parameters measured were wood density, fresh moisture content (FMC), equilibrium moisture content (EMC), total tangential shrinkage (TS), radial shrinkage (RS), longitudinal shrinkage (LS) and T/R ratio (T/R). The result showed that total averages of wood density, FMC, TS, RS, LS, and T/R were 0,45 gr/cm3; 118,40%; 7,63%; 3,53%; 0,71% and 2,23% respectively. Differences on wood physical properties of three spacing were found at FMC, TS and LS; while other properties were relatively not different. Based on the density, FMC and dimension change A. Mangium wood grown in 2 m x 4 m plantation spacing showed the best performance, that followed by 3 m x 3 m and 2 m x 3 m. Based on axial orientation, wood density tend to increase from bottom to upper stem, FMC, EMC, and TS, while other properties were not different. Based on radial orientation, the wood density and TS tend to increase from near the pith to near the bark, while FMC and LS have reversed pattern.

Abstract

Cultivation of albizia as high priority of community forest of West Java in large scale have turned into monoculture stand. These stand has become vulnerable to insect attack such as bagworm. Attack of bagworm took place in the dry season causing growth retardation which in some cases leads to tree death. The aim of this research is to examine the affect of leaf extract of Toona sureni and extract of Beauveria bassiana fungi to kill bagworm and also compare level effectively with organofosfat synthetic insecticides. The result showed that at 7 day after application, highest mortality of bagworm were found on trees treated with T. sureni leaf extract (100%) followed by B. bassiana (92,31%) and organofosfat synthetic insecticides (76,15%).
