 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of planting times and plant densities of top-shoot cuttings on multiplication of breeder seed potato) ผู้เขียน: Md. Abdullah Al Mamun, Abdullah Al-Mahmud, Mohammad Zakaria, M. Mofazzal Hossain, Md. Tofazzal Hossain สื่อสิ่งพิมพ์:pdf AbstractTop-shoot cuttings were planted with the whole tuber (as a control) at different dates using three spacings at the Horticultural Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University to evaluate the performance of top-shoots as planting material and to determine the optimum time of planting and the optimum spacing for top-shoot cuttings as planting material for breeder seed production. The survival of top shoot cuttings was more than 97.8% irrespective of the planting time and plant spacing. Significant variations were found among the treatment combinations for plant height at 45 and 60 days after planting (DAP), foliage coverage at 45 and 60 DAP, number of branches per plant, number of tubers per plant, individual tuber weight, tuber yields per plant and per hectare yield. The highest mean yield (46.57 t/ha) was produced by whole tubers planted on 10 November with 50 10 cm spacing which was similar to whole tubers planted on 1 November with 50 10 cm spacing. On the other hand, plants from top-shoot cuttings yielded 34.82 t/ha in T3S2 followed by T1S1 (33.34 t/ha), T3S3 (30.70 t/ha). The total yield of potato increased 122.8% from a single, early crop due to taking two repeated cuttings compared with 89.6% from a single late crop. Early planting of top-shoot cuttings with closer spacing (50 10 cm and 50 15 cm) is recommended for the multiplication of breeder seed potato. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Comparative Study of Artificial Diet and Soybean Leaves on Growth, Development and Fecundity of Beet Armyworm, Spodoptera exigua (Hubner) (Lepidoptera : Noctuidae)) ผู้เขียน:Md. Abdullah, Ouab Sarnthoy, ดร.สุดาวรรณ เชยชมศรี สื่อสิ่งพิมพ์:pdf AbstractAn artificial diet and soybean leaves were used in rearing the larvae of beet armyworm, Spodoptera exigua (Hubner) (Lepidoptera : Noctuidae) in laboratory condition. The artificial diet was composed of soaked mungbean, baking yeast, methyl paraben, sorbic acid, ascorbic acid, casein, choline chloride, agar, vitamin, formalin and distilled water. Survival of larvae on artificial diet (96.67%) was higher than those reared on soybean leaf (63.64%). Weight of larvae and pupae reared on artificial diet were significantly higher than those of the larvae and pupae fed with soybean leaves. The larval and pupal periods of those fed with artificial diet were 15.7 ? 0.84 and 6.73 ? 0.51 days respectively, whereas, those fed with soybean leaf were 18.65 ? 0.83 and 8.5 ? 0.52 days respectively. The average number of eggs laid was 577.9, when the larvae were reared on artificial diet. However, it was 472.5 when the larvae were reared with soybean leaf. The female and male life spans were 14.6 and 11.4 days on artificial diet and were 13.1 and 10.2 days with soybean leaf. Without feeding, the adult showed a life span of 6.29 ? 1.42 and 5.3 ? 0.66 days in artificial diet and soybean leaf respectively. Three consecutive generations were reared on artificial diet. Pupal ratio from larvae was found closer among the generations. The sex ratio was more or less similar in the first and second generations but in the third generation males number increased considerably (1:1.72). |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Gamma Irradiation on Microbiological Quality, Protein and Amino Acid Profile of Edible Bird Nest Powder) ผู้เขียน:Norrakiah Abdullah Sani, Ong Kuan Yee, Mohd Khan Ayob, Muhammad Samudi Yasir, Abdul Salam Babji, Nazaruddin Ramli สื่อสิ่งพิมพ์:pdf AbstractThe effect of gamma irradiation was determined on the microbiological quality and amino acid profile of edible bird nest (EBN) powder. Seven doses of irradiation were used: 0.0 (control), 1.0, 2.0, 5.0, 7.5, 10.0, 20.0 and 30.0 kGy. The total plate count (TPC) of EBN samples that were inhibited or had TPC < 100 colony forming units (CFU).g-1 at 20.0 kGy was determined. An irradiation dose of 5.0 kGy was required to reduce the coliform and Staphylococcus aureus counts to below 100 CFU.g-1 and the yeast and mold counts to below 1,000 CFU.g-1, while for Escherichia coli, 1.0 kGy was sufficient to inhibit or reduce the count to below 100 CFU.g-1. Salmonella spp. was not detected in any sample. A minimum irradiation dose of 20 kGy was required to sterilize the EBN powder samples most effectively. The pH and water activity values of the samples were in the ranges 8.34–8.90 and 0.621–0.674, respectively. The microbiological quality changes of irradiated samples were caused by the gamma irradiation alone. Gamma irradiation at doses as high as 10.0 and 20.0 kGy did not produce significant changes in the amino acid profiles of the EBN samples compared to the non-irradiated samples. Gamma irradiation improved the microbiological quality of the EBN samples without affecting their amino acid profiles. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Water Stress on Plant Canopy, Yield Attributes and Yield of Potato) ผู้เขียน:Abdullah-Al-Mahmud, M. Mofazzal Hossain, Mohammad Zakaria, M.A. Khaleque Mian, M. Abdul Karim สื่อสิ่งพิมพ์:pdf AbstractFour potato clones of the International Potato Center with one check variety (Asterix) were planted in the third week of November 2010 at the Horticultural Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University to observe the effect of water stress on plant canopy growth, development and yield of potato. Plant heights, the number of leaves and leaf area of all the clones were significantly affected by water stress. Tolerant clones produced greater tuber dry matter under stressed conditions. The largest reduction in yield (greater than 50%) was found in the susceptible clones; the tolerant clones showed comparatively less yield reduction (less than 50%). The yield reduction caused by water stress was attributed mainly to the reduction in number of tubers per plant with small-sized tuber production. In addition, the percentage difference in dry matter in the tubers of susceptible clones was greater than in the tolerant clones due to the utilization of water from the tubers in the water stress treatment. |
 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Investigating the Effect of Microcredit on Hardcore Poor Household Income in Peninsular Malaysia) ผู้เขียน:Abdullah- Al- Mamun, Sazali Abdul Wahab, Abu Bakar Sade สื่อสิ่งพิมพ์:pdf AbstractThis study employed a cross sectional design with stratified random sampling to examine how Amanah Ikhtiar Malaysia (AIM)’s microcredit program improved the income of hardcore poor households in Peninsular Malaysia. This study designed and tested a structural equation model to examine the underlying relationship between group-based microcredit programs and how they affect household income. It was evident that AIM’s microcredit program increased household income. Therefore, this program should focus on providing adequate training, flexible and diversified loan programs, and increasing outreach. Policies should also be reviewed and re-organized to increase the employment rate and to reduce repayment problems and the dropout rate. |

Abdullah, Ouab Sarnthoy, Somchai Isichaikul, ดร.ศิริพรรณ ตันตาคม, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractField experiments were conducted during dry and wet seasons (1999-2000) at Kamphaeng Saen Campus of Kasetsart University, Nakhon Pathom, Thailand to evaluate the efficacy of cypermethrin 10 EC, neem extract (Azadirachtin 0.1%) and Bacillus thuringiensis var. kurstaki (53,000 SU/mg) in controlling the major insect pests of vegetable soybean. Melanagromyza sojae, Spodoptera litura, Spodoptera exigua, Helicoverpa armigera, Lamprosema indicata, Etiella zinckenella and Bemisia tabaci were the most abundant species in both seasons. Insecticides were sprayed at 10 days interval until harvest. Cypermethrin showed significantly better control among the treatments. Neem extract moderately suppressed the insect pests with statistically significant efficacy over the control. B. thuringiensis var. kurstaki showed less efficacy than neem extract but exhibited statistically significant efficacy over the control in most cases. Highest yield was recorded in cypermethrin treated plot (9.83 t/ha) followed by neem extract (8.39 t/h), B. thuringiensis var. kurstaki (7.98 t/ha) and control (6.22 t/ha) in dry season whereas yields were 5.83, 4.83, 4.0 and 2.83 t/ha for cypermethrin, neem extract, B. thuringiensis var. kurstaki and control in wet season, respectively. Additionally, Menochilus sexmaculatus and spider were found less in cypermethrin treated plots whereas in other treatments they were significantly higher in number. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Solution Concentration on MnS2 Thin Films Deposited in a Chemical Bath) ผู้เขียน:Anuar Kassim, Tan Wee Tee, Ho Soon Min, Abdul Halim Abdullah, Ahmad Haziq Jusoh, Saravanan Nagalingam สื่อสิ่งพิมพ์:pdf AbstractManganese sulfide (MnS2) thin films were deposited from aqueous solutions at room temperature on indium tin oxide glass substrates by the chemical bath deposition method. The method employed was cheap, simple and did not require any special set-up process. The chemical bath contained manganese sulphate, thiourea and triethanolamine solutions. The effect of various solution concentrations on crystalline films was determined. The structure, morphology and optical absorption of the films were analysed using X-ray diffraction, atomic force microscopy and UV/Vis spectrophotometry. Formation of a cubic structure with preferential orientation along the (210) plane was confirmed from structural analysis. From atomic force microscopy images, the thin films prepared at higher concentration showed complete coverage of material over the substrate compared to the films prepared at lower concentration. The band gap energies of films ranged from 3.5 to 3.8 eV, depending upon the solution concentration. |

Abdullah, Ouab Sarnthoy, ดร.ศิริพรรณ ตันตาคม, รองศาสตราจารย์, Somchai Isichaikul, ดร.สุดาวรรณ เชยชมศรี สื่อสิ่งพิมพ์:pdf AbstractField collected larvae of beet armyworm, Spodoptera exigua (H?bner) were reared and evaluated for resistance against cypermethrin 10 EC, neem extract (Azadirachtin 0.1%) and Bacillus thuringiensis Berliner var. kurstaki (53,000 SU per mg) for 12 generations under laboratory condition by using leaf dip bioassay. Cypermethrin showed LC50 value of 251 ppm at F1 generation and decreased gradually to onward generations resulting LC50 value of 90 ppm at F12 generation for non-selection, whereas LC50 increased rapidly with a value of 8625 ppm at F12 generation under selection pressure. Neem extract exhibited LC50 value ranging from 3.98 ppm to 9.99 ppm for non-selection, whereas under selection pressure LC50 ranged from 4.38 ppm to 13.04 ppm throughout the generations. Bacillus thuringiensis var. kurstaki showed LC50 value which ranged from 7.3 ? 106 SU/L to 15.9 ? 106 SU/L for non-selection, and selection for resistance monitoring gave LC50 value ranged from 7.6 ? 106 SU/L to 73.9 ? 106 SU/L . Compared with non-selection strain, selection strain exhibited 95.83-fold, 1.44-fold and 5.6-fold increase in the LC50 for 12 generations against cypermethrin, neem extract and Bacillus thuringiensis var. kurstaki, respectively. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Cypermethrin Insecticide Residues in Vegetable Soybean, Glycine max (L.) Merrill, at Different Days of Pre-harvest Interval) ผู้เขียน:Md. Abdullah, Ouab Sarnthoy, ดร.สุรัตน์วดี จิวะจินดา สื่อสิ่งพิมพ์:pdf AbstractThe experiments were conducted to investigate cypermethrin insecticide residues in vegetable soybean at different days of pre-harvest interval for two growing seasons. Soybean pods were collected at 0, 1, 3, 5 and 10 days after last application with cypermethrin. Residues were extracted from pods and determined using gas liquid chromatography with an electron capture detector. Cypermethrin when applied at the rate of 100 g ai/ha using a knapsack sprayer showed a mean residue level of 0.71 and 0.52 mg/kg at 0 and 1 day, respectively, in dry season (December- February) whereas the residues were 1.62 and 1.17 mg/ kg at 0 and 1 day, respectively, in early wet season (April-June). A pre-harvest interval of 3 days was found safe (0.42 mg/kg) for consumers in dry season whereas early wet st season soybean exhibited residue level of 0.48 mg/kg at 10 day which fell below maximum residue limit of 0.5 mg/kg as prescribed by Food and Agriculture Organization/World Health Organization. Therefore, a pre-harvest interval of 10 days should be considered for cypermethrin residues in vegetable soybean to avoid any health risk of consumers. The dissipation rates of cypermethrin on soybean pods were more or less similar at the same days for both seasons which was 70% (based on 0 day) at 10 days. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Regeneration efficiency based on genotype, culture condition and growth regulators of eggplant (Solanum melongena L.)) ผู้เขียน:Md Abdul Muktadir, Muhammad Ashraful Habib, Md Abdul Khaleque Mian, Md Abdullah Yousuf Akhond สื่อสิ่งพิมพ์:pdf AbstractSeveral experiments were carried out to establish an efficient regenerating protocol for cultivated eggplant varieties. Among the five varieties cultured on Murashige and Skoog (MS) medium with free plant growth regulator (PGR), Nayantara performed better considering the number of shoots/explant (2.48). Considering explant types and culture conditions, better performance was observed (3.68 shoots/ explant) when seed germination in the dark was proceeded by bottom hypocotyl segments cultured under dark conditions. A higher rate of shoot regeneration was observed in Nayantara when cultured in Zeatin Riboside (ZR) and Thidizuron (TDZ) supplemented MS medium. The highest number of shoots per explant was produced on MS medium supplemented with 2.0 mg/L ZR and 0.1 mg/L indole acetic acid (6.65 shoots/explant). Proliferation and elongation of the regenerated shoots were obtained in the MS medium with free PGR. The best rooting performance was observed in MS medium supplemented with 2.0 mg/L indole butyric acid. Plantlets with well developed roots and shoots were successfully transferred to soil. |
