Abstract

Vanda tricolor Lindl. var. suavis is an Indonesian wild orchid that has been rare in nature,  so it needs attention to take care and conserve them.  The objective of the research was to investigate the effect of coconut water and / or tomato juice on the growth of protocorm of V. tricolor Lindl. var suavis from Bali grown in vitro. The experiment was laid out in the factorial design, with two factors (coconut water/CW and tomato juice/TJ), each contained three concentration (CW: 0, 100, and 200 cc L-1; TJ: 0, 100 and 200 g L-1) resulted in nine combination of treatments and replicated four times.  The results showed that tomato juice with concentration of 100 gL-1 or 200 gL-1 promotes growth of protocorms of Vanda tricolor Lindl. var. suavis from Bali regardless the presence of  coconut water.

Abstract

The main problem of the use of N fertilizer in paddy soil Vertisols is the low efficiency. Urea-humic acid applications at certain dosage are believed to increase rice growth and production. This study was aimed to examine the effect of urea and urea-humic acid to the amount and form of N-available, N uptake, plant growth, and the production of rice. Five dosage levels of urea-humic acid were applied for rice on Vertisols. Results of the research showed that the urea-humic acid fertilizer could increase the content of N-NH4+ soil at 28 days and N-NO3- soil at 42 days. The urea-humic acid could improve plant height, number of tillers, and total dry weight. The highest rice production is achieved by 100% humic acid-urea, especially on parameters of dry weight effectively harvested and effectively milled, with 5.56 tons and 4.61 tons per hectare respectively. Correlation between soil N-NO3- level with soil N-NH4+  level was significant at p = 0.05 (r = 0.871). Efficiency of urea-humic acid fertilizer at 100% recommended dosage (200 kg urea-humic acid) to the dry weight of  effectively harvested crop with dry weight of effectively milled crop was 22% compared to the recommended urea fertilizer (200 kg ha-1).

Abstract

The objectives of the research were to study the shift of weed compositions in sweet corn field treated with organic compost and chemical weed controls and to compare the effect of treatment combinations on weed growth, weed biomass and sweet corn biomass. The research was conducted in Bengkulu, Indonesia, from April to July 2014.  Results showed that the number of weed species decreased after the trials from 14 to 13.  There was a shift in weed compositions because 5 species of weeds did not emerge after the trials, but 4 new species were found.  Chemical weed control using a herbiside mixture of atrazine and mesotrione applied during postemergence was the most effective method  to control weeds, which was observed on decreased weed emergence and weed biomas down to 22.33 and 25.00 percent of control, respectively.  Subsequently, biomass production of sweet corn increased up to 195.64 percent with the same trials.  Biomass of weeds and sweet corn were also affected by the organic composts.  Weed biomass was inhibited with treatment of composted empty fruith bunches of oilpalm, whereas significantly increased of sweet corn biomass were observed in the plots of organic manure.

Abstract

Agarwood is a resin product produced by particular trees and has a certain high comercial value. In Central Bangka Regency, agarwood is the main commodity of forest. The research was aimed to determine the dynamic population of  rhizobacteria and its potential as a biological control agent to control Fusarium disease in the nursery of agarwood  (Aquailaria  malaccensis Lamrk). The research was carried out by using exploration and identification methods. Sixty nine bacterial isolates were obtained from 20 samples. The samples taken were from Pangkalan Baru and Koba districts. After selection process, 49 bacterial isolates were tested for the capacity of inhibition. Results showed that 37.50 % of the bacterial isolates indicated a strong inhibition capacity, meanwhile 58.33% indicated a moderate and only 4.70% possessed a weak inhibition. Pseudomonas fluorescens, P. aerogi-nosa, P. malthophilia and Klebsiella pnemoniae were identified from the selected isolates. These bacteria were potentially able to protect plants against Fusarium disease and to promote plant growth. This research needed to be continued at the field level in order to know the real effects on plant.

Abstract

Carnation has a highly economic demand of cut flower in Indonesia.  Field observations in West Java Indonesia was conducted in order to find the typical mottle symptoms that was a suspect caused by a virus disease. Identification of the virus was respectively conducted by performing ELISA test with four anti sera and characterizations held by bioassay, observing of virion particles, detecting of nucleic acid by RT-PCR and nucleotide sequencing. Total of 403 samples were collected from plants with or no virus-like symptoms. Among those all tested, 83% were found to be infected by Carnation mottle virus (CarMV), but negatively against Carnation ringspot virus (CRSV), Carnation laten virus (CLV), and Carnation vein mottle virus (CVMV) antisera. By mechanical inoculation, the virus was able to infect systemically Cenopodium quinoa and locally infect on others. However on Phalaenopsis sp and Gomprena globosa, there was symptompless found. The isometric CarMV particles size was approximately 30 nm. RT-PCR using specific primers of CP gene of CarMV successfully amplified a DNA sized 1000 bp.  CarMV West Java Indonesian (Idn-WJ) isolates possessed the highest nucleotide and amino acid homology with CarMV from Spain and was in the same cluster with CarMV from China, Taiwan and Israel.

Abstract

In management of thrips on strawberry, farmers usually use synthetic insecticides. Synthetic insecticide is not effective to control thrips and produce residual effect on crops. Insecticidal residue is dangerous for human, natural enemies and environment widely. Therefore, it is necessary to find an alternative thrips pest control on strawberries, through integrated pest manage-ment (IPM) implementation. Research was aimed to determine the effect of IPM technology for Thrips sp. on strawberry plantation. Research was conducted on strawberry plantation by comparing IPM and conventional plots, in Kusuma Agrowisata Batu from April to July 2009. Variables were used such as the number of larvae, adult population and damage intensity caused by Thrips sp., and fruit production. Data was analyzed by t-test on 5%. The results showed that the average larva and adult population of Thrips sp. on IPM plot were higher than conventional plot, 1.12 and 0.50 for larva and 0.87 and 0.27 for adults respectively. The damage intensity of strawberry crops on IPM plot was higher than conventional plot, 11.69 and 5.98% respectively. Based on average fruit production, IPM plot was higher than conventional plot, 48.32 g and 39.24 g respectively.

Abstract

Over the function of the upstream region watersheds causes the soil susceptible to degradation of soil fertility. Agroforestry systems that have been implemented should be reviewed to determine their effectiveness in improving soil fertility using a soil quality index. The varieties of soybean that cultivated in the study site were Grobogan, Kaba, and Argomulyo. The variables of this study consists of organic-C, pH, cation exchange capacity (CEC), total-N, available-P, available-K, Na, Ca, Mg, base saturation, and electrical conductivity (EC). Soil quality index calculation performed on selected outcome variables principal component analysis (PCA) which is then multiplied by the weights index on each PC. Selected variables from PCA consist of available-P, available-K, base saturation, and pH. Soil quality index values for all types of Agroforestry in the upstream of Bengawan Solo river basin (Wonogiri) is under secondary forest (<4.1) so that it can be concluded that the adoption of Agroforestry in the upstream of Bengawan Solo river basin has not effect on soil quality based on soil functions in the recycling of nutrients. Mean of soybean grain yield in agroforestry system are higher than the mean of national soybean production, but there are an obstacle such as light conditions.

Abstract

This study aimed to develop the cacao (Theobroma cacao L.) in vitro regeneration system through somatic embryogenesis on kinetin supplemented DKW medium and somaclonal variation assessment using SSR markers.  Callus were initiated from basal petal and staminoid explants cultured on callus induction (CI) medium contained DKW basalt salts and kinetin:2,4-D ratios of  1:15.5, 1:7.8 or 1:3.9 and then transferred onto secondary callus growth (SCG) medium contained WPM basalt salts and kinetin:2,4-D ratios of 1:7.8 or 1:3.9. The calli were then subsequently transferred onto embryo development medium contained DKW basal salts with or without the addition of amino acids, adenine or activated charcoal for the formation of somatic embryos. Nine cacao genotypes were tested for their  ability to develop somatic embryos. Results of this study indicated DKW medium supplemented with Kinetin in combination with 2,4-D effectively induced cacao somatic embryogenesis. The highest somatic embryos formation was abtained from kinetin:2,4-D ratio of 1:3.9 and 1:7.8 in CI and SCG medium respectively. Cacao genotype responses were highly explant type dependent. The developed method resulted in a high percentage of somatic embryo formation (5.6-66.7%), germination (50%)  and plantlet conversion (65%) and a medium percentage of somaclonal variations based on SSRs marker analysis.

Abstract

This research aimed to determine the best land and water management by arrangement of plant spacing, irrigation, and drainage of rubber plantation in order to improve rubber plantation productivity. This research was done using The WaNuLCAS (Water, Nutrient and Light Capture in Agroforestry System) model to determine the best land and water management under several scenario combinations of two factors. The first factor was rubber plant spacing arrangement system, which consisted of three levels, i.e. single row (3 x 7 m), single row (3 x 6 m) and double row (2 x 6 x 14 m). The second factor was water management treatment, which consisted of four levels, i.e. without irrigation and drainage, irrigation in dry season, drainage in wet season, and irrigation and drainage in dry and wet season respectively. The results showed that drainage treatment could enhance rubber plantation productivity. Moreover, rubber plantations which were using single row (3 x 7 m), single row (3 x 6 m) and double row (2 x 6 x 14 m) had no significant difference on latex production per hectare.

Abstract

Dioscorea spp. is the edible tubers from Dioscoreaceae family. Dioscorea is also an important crop which serves as a staple food and medicine. Discoreaceae exploration collecting mission had been conducted in 10 Districts of Pasuruan, East Java. Forty-four accessions were obtained during the exploration. It comprised of 5 species and 29 varieties i.e. 17 varieties of Dioscorea alata L., 8 varieties of Dioscorea his-pida Dennst., 2 varieties of Dioscorea esculenta (Lour.) Burkill., 1 variety of Dioscorea pentaphylla L. and 1 variety of Dioscorea bulbifera L. The results showed that morphological characteristic features of Dioscorea spp. tubers were broadly varied among species and even within varieties at the same species. Dioscorea spp. varieties ori-ginated from Pasuruan were mostly character-ized by its tuber shape, tuber flesh colour, outer and inner skin colour and  tubers skin texture. Based on the interviews to local farmers, D. alata and D. hispida varieties were still widely grown because of its high tuber yields and its most acceptable taste than other Dioscorea species.
