Abstract

In 2011, we found a new bacterial disease characterized by wilt, dwarf and blight symptoms on sweet corn in Batu, East Java, Indonesia. The objective of this study is to characterize the causal agent of the disease. In this study, several assays were conducted, including hypersensitive response, pathogenicity, physiological and biochemical characteristics, PCR detection  using two specific species primer pairs for Pantoea stewartii pv. stewartii, and homology analysis of 16S rRNA gene sequence. Four Gram-negative, non-motile, facultative anaerobic bacteria were isolated from the diseased tissue. Only two strains, BD1 and BB2, gave positive result in hypersensitive reaction, pathogenicity, and Koch’s postulate assays. BB2 and BD1 strains also showed positive results in the PCR amplification using specific primers derived from the P. stewartii subsp. stewartii 16-23S gene region of but showed negative result when using primers derived from P. stewartii subsp. stewartii hrpS gene region. Sequence of partial 16S rRNA gene of BD1 and BB2 showed highest homology at 96%  to P. stewartii subsp. stewartii strain ATCC 8199 (NR. 044800.1). This results suggest that bacterial pathogens isolated from sweet corn in Batu were strains of  Pantoea spp. Keywords : Zea mays, Pantoea spp, wilt, leaf blight, PCR <w:LsdException Locked="false" Priority="70" SemiHidde

Abstract

Frond and leaflet residues from pruning of oil palm which are applied as mulch on oil palm plantation will decompose and can be source of organic matter and some essential nutrients. Information about how much the released nutrients from the decomposition processes of frond and leaflet of oil palm is limited. The objective of this research was to study the period (two years) patterns of nutrient release and decomposition of frond and leaflet of oil palm at different burial depth (0 to 30 cm) in peat soil. Decomposition of frond and leaflet of oil palm did not have a different pattern in mass loss, chemical content changes of C/N, N content, P content, P released, however, it has different pattern in N released. During two years of decomposition, frond and leaflet lost 88% and 86% of its initial weight and released 51% and 83% of N, also it released P 87% and 93% respectively. Frond and leaflet from pruning of oil palm should be returned to plantation area for one source of nutrients beside fertilizer.

Abstract

The highest expense on sugarcane management is fertilization in which one of them is phosphate fertilizer produced by imported raw materials.  An innovation was made by using the local phosphate deposits with low reactivity processed further to improve their effectiveness for sugarcane. The objective of this study was to investigate the growth, yield and quality of sugarcane as affected by bio-superphosphate (Bio-SP) application on a highly weathered tropical soil. A nine-month field experiment was conducted at Jatitujuh Sugar Mill area, West Java, Indonesia, comparing between sugarcane fertilized with Bio-SP to replace conventional single superphosphate (SP-36) and that fertilized with SP-36. Urea and MOP (Muriate of Potash) were applied at similar dosages as recommended by division of Jatitujuh Sugar Mill Agronomy Research. Bio-SP was formulated by reacting a Central Java Rock Phosphate with liquid culture supernatant (LCS) and phosphoric acid characterized by 33% total soluble P2O5, 23.1, and 10.7 % citric acid and water-soluble P2O5, respectively. The results indicated that Bio-SP at 50% dosage of SP-36 was as effective as the SP-36 in supporting sugarcane growth and improved yield up to 8% as crystal sugar.  Further consequence of this finding is that the application of Bio-SP reduced 9.2% of fertilizer cost for sugarcane.

Abstract

In vitro regeneration of buds and shoots via organogenesis in two genotypes of snake plants (Sansevieria trifasciata) were established. Leaf segments (1 x 1cm) of 'Hahnii' and 'Lorentii' were cultured on Murashige and Skoog (MS) basal medium containing 2,4- dichlorophenoxyacetic acid (2,4-D) for 1 week, transferred into MS medium without plant growth regulator (MS0) for 1 week, and then cultured on MS medium containing different concentrations of N6-benzyladenine (BA) at 0, 0.1, 0.25, 0.5, 1.0 and 2.0 mg/l in three times of serial passages with 4 week intervals. The results showed that regeneration of S. trifasciata was established via indirect organogenesis. 'Lorentii' was more responsive on shoot regeneration than 'Hahni'. The most suitable BA concentration for shoot bud and shoot regeneration for both cultivars was 2 mg/l. Explants of 'Lorentii' cultured on MS medium containing 2.0 mg/l BA produced 8.6 shoot buds and 3.4 shoots per explant after 14 weeks. Shoots derived from both cultivars were successfully ex vitro rooted and acclimatized in the greenhouse with high survival rate, i.e., from 96 -100%. Keywords : organogenesis, Sansevieria trifasciata 'Hahnii' and 'Lorenti', benzyladenine

Abstract

The effort to reduce chemicals has become an important issue in floriculture agribusiness. The chemicals included fungicides for white rust control in chrysanthemum. The combined application of synthetic fungicide with biological agent and botanical fungicide were expected not only to reduce synthetic fungicide application, but also suppressed the white rust attacks. The research was conducted at the Indonesian Ornamental Crops Research Institute (IOCRI). A factorial randomized complete blocked experiment was designed to facilitate combined applications of hexaconazol-50 (SFH-50), antagonist microbe Corynebacterium sp. (Cor-5) and formulated botanical fungicide CEES 50EC (ES-50). The results showed that the combined SFH-50 with Cor-5 and ES-50 merely affected the disease intensity, yet less on white rust incidence, period of disease emergence, plant growth, flower production and quality. All combined applications of SFH-50 with Cor-5 and ES-50 showed lower disease intensity than single SFH-50. Higher suppressions were detected on 1 ml/l SFH-50 + 5 ml/l Cor-5-3 and 1 ml/l SFH-50 + 2 ml/l ES-50-3. The use of antagonist microbe and botanical fungicide singly or in combination with synthetic fungicide could reduce with the higher affectivity than single synthetic fungicide application.

Abstract

Arbuscular mycorrhizal fungi (AMF) are ubiquitous organism that forms association with the root of most terrestrial plants. AMF association also influence soil fertility through the enhancement of chemical, biological and physical content. In this study, we enumerated AMF spores from rhizosphere of Tithonia difersivolia as an indicator of soil fertility. The results showed that the most fertile soil had the highest AMF spores density. This research has confirmed that AMF has high interaction with organic carbon, organic matter, total phosphorus, cation exchange capacity, water level, soil fungi and soil bacteria. Partial regression analysis revealed the mathematic equation for their interaction. This equation used the abundant of AMF spores as an indicator for chemical, biological and physical fertility of the soil.                 Keywords: Arbuscular mycorrhiza fungi (AMF), indicator, soil fertility, Tithonia difersivolia

Abstract

Kencur (Kaempferia galanga L.) has been recognized as a medicinal plant used by many ethnic groups in Indonesia. Up to present time, information on the diversity of the respected plant is still limited. The aim of this research was to reveal the genetic diversity of K. galanga in Indonesia as a baseline medicinal plant database. Inter-Simple Sequence Repeat (ISSR) molecular markers were employed to analyze the genetic diversity information of K. galanga from 12 selected locations in Indonesia where ethnic groups used the plant. Dice index similarity was used to calculate a similarity index, and Unweighted Pair Group Method Using Arithmetic Mean (UPGMA) was used to constructing a dendrogram. Ten selected ISSR primers generated 104 amplified DNA fragments, of which 98 fragments (94.2%) were polymorphic. The genetic similarity index among accessions ranged from 49.6–93.3%, indicating a high level of genetic diversity in K. galanga. The ISSR markers were thus able to genetically differentiate K. galanga accessions.

Abstract

Over the last few years, the bagworm Metisa plana Walker (Lepidoptera: Psychidae) has become an important pest of oil palm, especially in North Sumatra. Recent report suggested that the bagworm has also been found in Lampung. The report requires preliminary survey to assess M. plana status and to prepare an effective control measure for the pest. This study was conducted to determine the relative density of M. plana in North Sumatra and Lampung and to compare the effectiveness of the spraying versus fogging application to control M. plana in oil palm fields. The observation confirmed that in 2010 M. plana colonies have developed in Lampung with an average relatively similar to that in North Sumatra during 2005. The finding implies that monitoring should be taken routinely to anticipate further development of the bagworm population in Lampung. Overall results of carbosulfan treatments suggested that the fogging insecticide technique was potentially as effective as spraying technique. This finding could be beneficial for bagworm control program due to the extensive areas of oil palm and the large size of canopy. A more thorough experiment is required to explore the most economical doses and to select effective insecticides to control M. plana. Keywords : Metisa plana Walker (Lepidoptera: Psychidae), bagworm, oil palm, spraying vs. fogging application
