  The main objective of this study was to determine the extent of adoption of BRRI dhan47 (A saline resistant High Yielding Variety (HYV) of rice have been developed very recently by Bangladesh Rice Research Institute (BRRI) suitable for cultivation in costal area) in Satkhira district. Data were collected from randomly selected 90 households’ heads using pre-tested interview schedule during June to August, 2010. After collection, data were coded for processing and analysis. SPSS was used to perform the data analysis. Statistics like frequency counts and percentages as well as mean and standard deviation were calculated. Coefficients of correlation (r) was computed to find out the relationship between adoption of BRRI dhan47 and their selected socio-economic characteristics. Majority of the respondents were young aged (47.8%) having primary level education (45.6%), small family size (60%), medium farm size (51.1%), medium (75.6%) annual income, medium (63.3%) extension contact, poor (50%) training experience, high (38.9%) innovativeness, medium (70%) level knowledge on rice cultivation. Majority (52.3%) of the respondents had low adoption of BRRI dhan47 whereas 44.4% medium and only 3.3% under high adoption category. Farmer’s education, farm size, innovativeness, extension contact, knowledge on rice cultivation and annual family income showed significant and positive relationship with adoption of BRRI dhan47. Shattering, unavailability of salinity testing equipments and lack of rain water or irrigated water at tillering stage to escape salinity were the major problems faced by the farmers in cultivating BRRI dhan47. GO and NGOs should take immediate steps to disseminate salt tolerant rice varieties to bring the uncultivated areas under intensive cultivation as well as to ensure better livelihood of coastal farmers.

  Two triterpenes, β-Amyrin and 12-Oleanene 3β, 21β-diol, were isolated as a mixture from the chloroform soluble fraction of an ethanolic extract of Duranta repens stem. The structures of these two compounds were confirmed by IR, 1H and 13C-NMR spectral data. In acute toxicity test, the chloroform soluble fraction showed toxic effect on rats but compound 1 (mixture of β-Amyrin and 12-Oleanene 3β, 21β-diol) had no toxic effect on rat at 2 mg/kg/day b.wt. Biochemical and hematological profiles of rat`s blood of chloroform soluble fraction were found statistically significant. In histopathological experiment, some degenerative changes on cellular structure of liver, heart and kidney except lungs were found in chloroform soluble fraction treated rats.

  The aim of present study was to investigate the bioactivity (antibacterial, antifungal and cytotoxicity etc.) of the ethylacetate extract isolated from Streptomyces sp. Aspergillus sp. and Bacillus sp. from sewage of different regions of Bangladesh. The ethylacetate extract of Streptomyces sp., Aspergillus sp. and Bacillus sp. shown modest antibacterial and antifungal activities at the concentration of 200 μg disc-1. The maximum antibacterial and antifungal activities were shown by the Streptomyces sp. The minimum inhibitory concentration of the microbial extracts was between 64 to 128 μg mL-1 against test organisms. Brine srimp lethality bioassay was carried out for cytotoxicity measurement of the extracts and the LC50 values were calculated after probit transformation of the resulting mortality data. All the ethyl acetate extract showed lower cytotoxicity properties (Streptomyces sp. 42.37 μg mL-1, Aspergillus sp. 52.25 μg mL-1 and Bacillus sp. 47.51 μg mL-1) compared with the reference standard Bleomycin (0.41 μg mL-1) and Galic acid (4.53 μg mL-1).

  Objective: The present study was carried out to assess the consequence of supplementation of turmeric, ginger and their combination in the diets of broiler chickens and assessment in terms of feed intake, growth performance and economics of feeding. Materials and Methods: A total of 360 day old Cobb-500 chicks were randomly allocated to six dietary treatments each with three replicates of 20 chicks/replicate (n = 60). Six experimental diets were formulated in such a way that control diet (T0) contained neither turmeric nor ginger. Birds in group T1 and T2 were fed diets containing 0.50 and 0.75% turmeric, whereas birds in group T3 and T4 fed diet contained 0.50 and 0.75% ginger, respectively. Birds in group T5 fed diets containing a combination of 0.50% ginger and 0.50% turmeric with commercial feed. The feeding experiment was carried out for 32 days and different parameters measured included: feed intake, weight gain, feed conversion ratio, dressing percentage and blood parameters. Results: Feed intake of experimental birds in T4 group was higher compared to other groups, i.e., (T0, T1, T2, T3 and T5) without a significant level. A body weight gain (g/bird) was found to be significantly (p<0.05) higher in ginger (T3 group) and turmeric (T2 group) supplemented group as compare to T4, T1, T5 and T0 group. Feed Conversion Ratio (FCR) was significantly (p<0.05) lower in the T3 group as compare to other groups. The dressing percentage, thigh weight, back, neck, wing percentages and blood parameters (Hb, PCV and ESR) were not statistically different among control and other treatment groups. However, the relative weight of breast, wing, gizzard and proventriculus were significantly increased (p<0.05). The cost of production and return of birds was highly economical in treatment T2 as compared to other treatment groups. Conclusion: On the basis of the results of the study, it is concluded that supplementation of turmeric (Curcuma longa) improves the growth performance of broilers when added at the rate of 0.75% level as feed additives in broiler ration.

  The aim of the present study was to investigate the antimicrobial and cytotoxic activities of five newly synthesized ferrocene based complexes [Mn(FcCOO)2, A], [Co(FcCOO)2, B], [Ni(FcCOO)2, C], [Cu(FcCOO)2, D] and [Zn(FcCOO)2, E]. The maximum antibacterial (at the concentration 100 μg disc-1) and antifungal (at the concentration 200 μg disc-1) activities were shown by the manganese complex A followed by cobalt complex B. The minimum activites were shown by Zink complex E. The minimum inhibitory concentration of the complexes was determined against four pathogenic bacteria Bacillus subtilis, Bacillus megaterinum, Escherichia coli and Shigella shiga and the values of complex A were found between 16-32 μg mL-1. Brine shirmp lethality bioassay was carried out and all the complexes also showed cytotoxic effect compared with the standard bleomycin (0.41 μg mL-1).

  The present study was designed to investigate the antioxidant, analgesic and anti-inflammatory potential of the methanolic extract along with its organic soluble fractions of the herb Eclipta prostrata. In addition, total phenolic and flavonoid content and total antioxidant capacity were also determined. Antioxidant potential of the extract/fractions was evaluated by DPPH (1,1diphenyl-2-picrylhydrazyl), NO (nitric oxide) and ONOO¯ (peroxynitrite) scavenging assay method. Ethyl acetate fractions (EtOAc) showed highest scavenging activity in all the methods with IC50 value of 12.98±0.08, 45.98±0.07 and 14.45±0.18 μg mL-1 for DPPH, NO and ONOO- assay method, respectively. In reducing power assay, EtOAc fraction also showed significant (p<0.001) activity. Further, the extract/fractions were studied for their analgesic (hot plate, tail immersion and acetic acid induced writhing test) and anti-inflammatory (carrageenan induced paw edema in rats) activities at a dose level of 200 and 400 mg kg-1 body weight. Among all the extract/fractions, EtOAc fraction showed a dose dependent and significant (p<0.005, p<0.05) analgesic activity in all the tested method. EtOAc fractions also reduced the paw edema considerably (86.80% inhibition after 3 h, p<0.005, p<0.05) in dose dependent manner compared to carrageenan induced rat. Altogether, these results suggest that the MeOH extract and its organic soluble fractions could be used as a potential antioxidant, analgesic and anti-inflammatory agent.

  Anthers of three rice cultivars having late uninucleate microspores were studied for induction of haploid rice plants. Anthers were cultured on Z2 medium supplemented with various combinations and concentrations of auxins and kinetin (cytokinin). The best callusing from cultured anthers obtained in 2 medium containing 2,4-D 2 mg l-1, NAA 2.5 mg l-1 and kin 0.5 mg l-1. For regeneration of haploid plantlets anther derived calli were transferred to modified MS medium enriched with kin 1 mg l-1, NAA 1 mg l-1, BAP 1.0 ml l-1 and incubated at 25±1OC in light. BRRI Dhan-29 produced both green and albino plants while BR-3 produced green plants only. Green plantlets obtained from BRRI Dhan-29 were examined and found to be 69.2% haploid plants.

  The study was to develop models that could be used to make efficient forecast of shrimp and frozen food export earning of Bangladesh. Two types of models, namely, Box-Jenkins type autoregressive integrated moving average (ARIMA) and deterministic type growth models, are examined to identify the best forecasting models for shrimp and frozen food export earning of Bangladesh. The study found that the ARIMA (2,2,0) was the best for both shrimp and frozen food export earning. Among the deterministic type models, the quadratic model is best for both the series. The study also reveals that the ARIMA model is more efficient for short-term forecasting than the quadratic model.

  Institute of Biological Science, University of Rajshahl, Rajshahi 6205, Bangladesh Department of Genetics and Breeding, University of Rajshahi, Rajshahi 6205, Bangladesh Fruit Research Station, BARI, Binodpur, Rajshahi, Bangladesh. A field experiment on lablab bean based intercropping system was conducted at the Botanical Garden of Rajshahi University during the winter of 1999-2000 and 2000-2001. The experiment was conducted in with sole lablab bean and other crops as like as lettuce and spinach and their intercropping combinations. The yield and yield components of lablab bean were influenced by intercrops and the lablab bean JessoreI/lettuce intercropping in 1:1 ratio gave the highest monetary return and land equivalent ratio (LER) of 2.00. The yield advantage was more in intercropping than all sole cropping systems, except when it was intercropped with spinach.
