Abstract

The attack of Mimegralla coeruleifrons on ginger plants and its role in carrying pathogens of wilt diseaseRhizome flics Mimegralla coeruleifrons (Diplera; Micropezidae) ac frequently oten found in the diseased ginger rhizome caused by Ralstonia solanacearum, bill it has nol been known which one made the irst damage. Experiments were conducted at laboratory and green house of the Research Institute for Spice and Medicinal Cops from September 1998 to I'cbruary 2000. to examine the attack of M coerulefrons on healthy and disease ginger plants and its role in carrying the pauiogen. Hie experiments consisted of three parts, ink-station of the fly in healthy and diseased ginger plants, disease tansmission and detection of R solanacearum in M coeruleifrons larvae and adults, fiingcr plants were grown in pot containing, sterile media The pots were placed in the field and the plants were inoculated with R solanacearum and iininoculatcd. then they were caged or uncaged. Adult lies (33 - 35 pairs) were introduced into the cage. The uncaged plants were allowed to be naturally invested by the flies. Disease transmission used adult Hies which were collected from diseased ginger plantation. The lies were fed with suspension of R solanacearum. then introduced into cages containing healthy ginger plants. The flies were also directly caged on healthy plants Detection of/?, solanacearum in larvae and adults was carried out by isolation on selective medium and ELISA techniques. Results showed that M coerulefrons mostly attacked the inoculated ginger plants. Tliere was no evidence of Iransmission of R solanacearum by the fly. whereas nearly 50% of the ield collected lics carried R solanacearum. These results tend to suggest that the attack of M. coerulerons occured ater the ginger has been infected by wilt disease and the ly can be a carrier of/? solanacearum.

Abstract

Effect of dilution of basic medium on ginger growth during conservation in vitroBasic medium dilution could affect the growth of the culture. The effect of basic medium dilution was evaluated at the laboratory of Research Institute for Spices and Medicinal Crops from October 1998 to June 1999. Sterile shoots of ginger were used as ex plants. Basic medium dilution from 3/4 MS, 1/2 MS, 1/4 MS and MS normal (control) were used as treatments. The media were enriched with BA 3 mg/1 and Sucrose 6%. The treatments wee arranged in a completely randomized design with three eplications. Results showed that all the dilution treatments inhibited the grow of the culture during live months of conservation period, especially on 1/4 MS + BA 3 mg/1 + Sucrose 6% . On the media, the number of shoots wee 3.55. Based on cultue performance the best medium for conservation was 1/2 MS + BA 3 mg/1 + Sucrose 6%. All of the culture was able to growth in regeneration media after they were conserved for ive months. Results of this experiment could be applied in reducing sub-cultue frequency to a new media and maintain the culture stability. e

Abstract

The stability of yield and quality of the new lines of Temanggung tobaccoThe productivity of Temanggung tobacco is relatively low. One of the causes of the low productivity is genetic deterioration. Fom a series of selection, four lines were potential to be developed. Befoe the new varieties are released they need to be tested at different locations in a central poducing area. The tests were conducted at 1 1 locations in Temanggung District rom 1995 to 1997. The lines tested included four selected lines, original population of Temanggung tobacco.from which the selected lines were produced, and Kemloko, a local variety generally planted by farmers. The trial, were designed as a randomized block in three replicates for respective location. Results showed that two of four tested lines i.e. 2258/2/1/1 and 2132/2/2/1/1 produced stable yield and quality. Compared with Kemloko (local variety) the dry sliced tobacco, grade index and crop index of 2258/2/1/1 increased by 17.57, 6.85, and 26.88% respectively and those of 2132/2/2/1/1 increased by 12.28, 16.03, and 31.88% respectively.

Abstract

Rearing of Helopeltis antonii Sign (Hemiptera; Miridae) on cucumberfruit and cashew shootHelopeltis antonii is well known as a major pest of cashew, cacao and tea plantations A suficient number of the insect is frequently needed for esearch purposes. Rearing of // antonii on cucumber fruit was conducted from October 1997 to May 1998. Under laboratory condition. total eggs layed were 3.2 per female per day, while female longivity was 18.9 days. Egg period was 6.1 days and the total hatched was 93.5 percent. The egg and the irst unlil the ifth instar nymph periods were 6.1; 2.3; 2.0; 1.8; 1.9 and 3.2 days espectively. The adults emerged from earing of 10, 20 and 30 newly hatched nymph were 7. 13. and 17 insects or 71.3; 65.0, and 58.0 percent respectively. Eggs and nymph periods on cashew shoot almost the same as on cucumber fruit. The hatched eggs on cutted cashew shoot was 12 percent, while on the shoot of cashew seedlings was 89.0 percent This study indicated that cucumber fruit is very suitable and easier as well as more economical for mass rearing of // antonii.

Abstract

The effect of soybean planting methods and dosage of nitrogen fertilizer for cotton on pest development and cotton yieldThe effect of soybean planting methods and dosage of N fertilizer for cotton on pests development and cotton yield was studied in Tanggungan, Pucuk, lanongan from July 1997 to March 1998 on wet land previousl grown with rice plant rice. Split plot design in three replicates was used, planting system of soybean (sowed and planted in a hole) was the main plot and the rate of N fertilizer (30 kg N/ha, 60 kg N/ha and 90 kg N/ha) was the sub plot. Urea and ZA were used as source of N; SP36 for P20, and KCI for KjO. The rate of SP36 was 50 kg/ha and KCI was 50 kg/ha. One third of the full dosage of N (ZA) and the full dosage of P]Oj (SP36) and K20 (KCI) were applied at the time of planting While 2/3 of N were applied 6 weeks after planting. Cotton variety used in this study was ISA 205 A and soybean was Willis. Cropping pattern was 2 rows of cotton and 5 rows of soybean. Planting space of cotton was (190) 60 cm x 30 cm (2 plants per hole), hence the population was 53 280 plants per hectare. Plant spacing of soybean was 30 cm x 20 cm (2 plant per hole), hence the population was 200 000 plants per hectare. Parameters evaluated were the growth of cotton plant (height and canopy); component of yield (vegetative and generative branch, square shedding and number of bolls), and population of pest. The results showed that increasing the dosage of N from 30 (50% of the recommended dosage) to 60 kg (recommended dosage) and 90 kg (150% of the recommended) resulted in increased population of H. armigera from 12.33 insect to 18.77 and 17.00 insect, Erias sp. from 93.17 to 51.50 and 51.50 and S. bigutulla fom 103.5 to 102.50 and 122.30 insects per plant. Increased population of pest was followed by increased frequency of spraying from 2.50 to 3.50 and 3.67 times. Application of 30 kg N/ha decreased the population of// armigera, Earias sp. and 5. biguttula. however, the highest yield of cotton (1 580.16 kg/ha) was gained by applying 60 kg N/ha. Soybean planted by broascasting method had greater effect on cotton and soybean yields than dibbling method.

Abstract

Coal briquette furnace engineering for Virginia tobacco curingA coal briquette furnace for curing Virginia tobacco has been designed and constructed in Research Institute for Tobacco and Fiber Cops, Malang, East Java Indonesia. The furnace design was tested in East Lombok, Nusa Tenggara Barat, fom August to September, 1997. The goal of this research is to provide an alternative fuel for curing Virginia tobacco and its burning system for the product of Virginia tobacco. The coal briquette funace model is similar with wood funace with a brick wall. 125 cm long and 72% of that part positioned at the floor of the barn. The height of the curve furnace was 120 cm and the width was 105 cm. Terminal of the furnace hole was connected with the irst heat exchanger pipe made from iron plate (d = 58 cm) and than with the second heat-exchanger pipe (d = 30cm) encircle in the funace loor. Waste of the smoke coal burning was discharged through two chimneys of 5 m in height.The honey-comb coal biquette has 12.5 cm x 12.5 cm x 8 cm dimensions and 5 500-6 000 kcal or 23 027-25 121 kJ/kg calorific value. Result of the experiment showed that using of the coal briquette-fuel heat (35-70°C) in a suitable for curing tobacco leaves. The cured-leaves quality was as good as the standard. Coal briquette consumption was 5.54 pieces or 6.36/kg of cured-leaves. Based on the coal briquette price of Rp. 100 per piece, the tested pumace model gave the BC-ratio = 1.03, NPV Rp 994 218 and IRR 29.02%. The break-event point was achieved at the briquette price of Rp. 119.23/piece.
