  An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from May to November 1998 to investigate the effect of green manures and different levels of nitrogen on tillering behaviour, dry matter production and yield of transplant aman rice (cv. BRRI dhan32). The experiment was laid out in a randomized complete block design with three replications. The experiment comprised of 3 green manuring crops viz., Sesbania rostrata, Sesbania aculeata and Crotalaria juncea and 5 levels of N viz., 0, 20, 40, 60 and 80 kg ha-1. Dry matter production was increased with the age of the plant and also increasing trend was observed irrespective of green manuring crops in combination with higher levels of nitrogen, but number of tillers hill-1 increased up to 67 days after transplantation. The highest dry matter production and the highest number of tillers hill-1 were obtained with the incorporation of S. rostrata in combination with 80 kg N ha-1. S. aculeata also exhibited similar behaviour in these regards. The highest number of effective tillers hill-1 and the highest grain yield were obtained with Sesbania spp. in combination with 40 kg N ha-1 but C. juncea showed comparatively poor performance in respect of the aforesaid parameters due to less amount of biomass added during incorporation.

  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).

  Plant tissue culture is the most commercially successful aspect of plant biotechnology, which has introduced an exciting new phase into plant propagation and breeding. This paper presents a research finding that establish an efficient regeneration method for mass propagation of sugarcane var. Isd 32 using shoot tip and folded leaf as explants. In this study, in vitro shoot tip and folded leaf culture techniques were used for mass propagation and quality production of sugarcane plantlets. The explants of sugarcane var. Isd 32 was cultured on MS + 1.5 mg L-1 BA + 0.5 mg L-1 NAA for shoot tip and MS + 0.5 mg L-1 Kin + 5.0 mg L-1 NAA for folded leaf. Culture after 30 days, about 90 and 80% of the shoot tip and folded leaf explants, respectively were successfully regenerated shoots. The average number and length of shoots from shoot tip explants was observed as 17.20±1.30 and 7.20±1.40 cm, respectively. Similarly, the average number and length of shoots from folded leaf explants was observed as 20.20±2.20 and 6.70±1.20 cm, respectively. Presence of callus and morphological variants were not observed during the passage of in vitro culture. There is no efficient regeneration technique that had been established for mass propagation of sugarcane var. Isd 32. The proposed technique can be used to enhance mass production of sugarcane crop economically especially with the present trend of demand of sugarcane in the region.

  An experiment was conducted to find out a suitable banana (Ranginsagar and Sabari) based intercrop combination of potato and mustard in the research field of Institute of Biological Science of Rajshahi University, Rajshahi-6205, during Rabi season of 2003-2004. Average over the two years, it revealed that the highest yield of banana was observed in Ranginsagar + potato (64.72 t ha-1) and the lowest in sole mustard (1.92 t ha-1). Combinations of Ranginsagar + potato intercropping showed better performance than other combination and sole crop in respect of gross return (Tk. 735219 ha-1), net return (Tk. 359794 ha-1) and benefit cost ratio (1.95). The highest land equivalent ratio (LER) was 1.82 in Ranginsagar + Potato followed by Sabari + potato (1.79) and the lowest in Sabari + mustard (1.60). The economic return was more in intercropping than all sole crops.

  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 carried out to investigate indirect damage of guava leaf in the form of wax and honeydew covering by the spiraling whitefly (Aleurodicus dispersus) was investigated in a guava orchard, Mymensingh, Bangladesh. Extent of leaf damage in twigs of different strata indicated that the upper most twigs had minimum wax and honeydew-covered leaves than the other twigs of guava plants. The results of the study on variation of leaf damage in different leaf position of twig showed that at early attacking stage the mean percentage of wax and honeydew covered leaves, was significantly higher in upper leaf position than in the middle and the lower leaf position and had the lowest level of whitefly infestation in the lower leaf position of the guava twigs. Results showed that with the build up of population in the month of December and January, wax and honeydew covered leaves were more in middle leaf position. The lower wax and honeydew covering in upper position were recorded in the later months due to rain and rapid growth of new flush, which remained non-infested.
