    Abstract: The present study is illustrated complete morphometric and meristic characteristics of fresh water fish, walking snakehead, Channa orientalis (Bloch & Schneider 1801), using nine linear dimensions and covering different fin-rays (i.e., dorsal fin, D; pectoral fin, P1; pelvic fin, P2; anal fin, A and caudal fin,C) from the wetland ecosystem Gajnar Beel in northwestern (NW) Bangladesh. Total 230 specimens of C. orientalis were collected from the Gajnar Beel in the time of January to December 2018 by several local fishing gears (e.g., cast net, gill net and square lift net (mesh size ranges: 1.5 - 2.5 cm, 1.5 - 2.0 cm, & ~2.0 cm, respectively). Different morphometric lengths were measured to 0.01 cm, and whole body weight (BW) was estimated 0.01 g for each individual. Fin rays and scales (including lateral line scale) were computed by a magnifying glass. All LWRs were highly significant (p 〈 0.0001) with the r2 values ≥0.978. Based on r2 value, LWR by BW vs. TL was the best fitted model among nine equations. However, the LLRs were also significant with r2 values ≥0.992. According to r2 value, LLR by TL vs. SL (TL = a + b × SL) shown the best fitted model among eight equations. The fin formula of C. orientalis is: dorsal: D. 29-35; Pectoral, P1. 12-14; Pelvic, P2. 5-6; Anal, A. 20-22; Caudal, C. 12-14. A double lateral line is present which continued with 12-13 scales in the first line and 26-28 scales in other line. The present study will be helpful for the species identification and resource management of C. orientalis in the Gajner Beel NW Bangladesh and other sub-tropical countries. J. Bio-Sci. 29(2): 53-60, 2021 (December)

    Abstract: The necessity of more food production from limited land enforced cropping intensification over-exploring the natural resources in Bangladesh. This field experiment was initiated to achieve improve and sustainable productivity of an intensive wheat-maize-rice cropping system with improved management of natural resources. Four levels of nutrient managements were tested under four soil management treatments starting with wheat crop sown in November 2009 and ending with the harvest of 8th wheat crop in the system during March 2017. Yield and yield contributing characters of component crops and soil properties were studied following standard methods. Soil management treatment of rice straw mulch application in reduced till-bed or well-till flat soil upon wheat sowing was equally effective in conserving soil moisture, enhancing wheat root development, reducing weed growth and thereby positively influenced spikes/m2 and finally wheat yield. Similarly, wheat straw mulch application contributed to ears/m2 and grain yield of maize. Nutrient levels of recommended fertilizers plus 5.0 t/ha cowdung resulted in yield improvement of wheat and maize throughout the years. However, neither nutrient management nor soil management alone but the combination of recommended fertilizers with 5 t/ha cowdung couple with rice straw mulching in wheat and wheat straw mulching in maize resulted in maximum wheat and maize yield over the years. Rice yield was similar for different treatment combinations until the 4th cropping cycle and thereafter rice yield was also improved by the residual effect of straw mulches. Crop residue mulching along with addition of organic and inorganic fertilizers was found to be a promising soil management technology for achieving sustainable increased productivity of wheat-maize-rice system.

    Abstract: A field experiment was conducted on a saline environment of Shatkhira to assess the feasibility of an intensive wheat-maize-rice cropping system with crop residue used as mulch, bed planting and fertilizer management to improve productivity. Three levels of fertilizers (Recommended dose of NPKS fertilizers, recommended fertilizers plus 50% additional K and S and recommended fertilizers with 2 t/ha ash) were assigned in main plots and four combinations of soil management and mulching (Conventional flat, Conventional with straw mulching @ 3 t/ha, Bed planting, and Bed with straw mulching @ 3 t/ha) were kept in subplots with three replications. Rice straw mulch was used after wheat sowing, wheat straw mulch was applied after maize sowing. Rice was puddle transplanted without mulch. Crop varieties like BARI GOM 25, BARI Hybrid Maize 7, and BRRI Dhan 39 were used for wheat, maize and rice, respectively. Chemical analysis of soils after two years of experimentation and the response of component crops for the two cropping cycles indicated that straw mulching either on bed or flat soil was equally effective in preventing rapid development of soil salinity in the dryer periods and thereby resulted in better stand establishment contributing to higher spikes/m2 of wheat and ears/m2 of maize. Available nutrient contents in soil, especially P (Olsen), B and K were improved when straw much was applied in bed or flat plantings. Application of ash with recommended fertilizer was effective in improving grain yields of component crops as compared to other fertilizer treatments without ash. The highest grain yield of wheat and maize was achieved when recommended dose of fertilizers plus ash with straw mulching were applied either in bed or flat soil condition for both the years. Treatment effect was not noted on rice yield in the first year, however the residual effect of treatments and its combinations became significant in the second year. Like wheat and maize, rice yield positively increased by fertilizer+ ash and mulching. Straw mulch and ash application contributed to soil salinity mitigation, favoured crop establishment and improved the yields of component crops.Bangladesh J. Agril. Res. 41(1): 1-15, March 2016

    Changes in the Saccharoid Fraction in Rats with Alloxan-Induced Diabetes or Injected with Epinephrine
    Oxford University Press (OUP) ; 1971

    In: Clinical Chemistry, Oxford University Press (OUP), Vol. 17, No. 9 ( 1971-09-01), p. 915-920
    Abstract: "Saccharoid fraction," defined as the nonglucose reducing substances in blood, increases both in hyperglycemia (blood glucose concentration exceeding 280 mg/dl) and hypoglycemia (blood sugar less than 65 mg/dl) in rats. This increase is not completely accounted for by glutathione, glucuronic acid, ascorbic acid, uric acid, and creatinine. Some of the constituents of saccharoid fraction seem to be insulin-sensitive. Alloxan not only produces diabetes in rats but also increases blood glucuronic acid, ascorbic acid, and uric acid. Estimated constituents of saccharoid fraction account for only 45% to 75% of the saccharoid fraction. The unaccounted-for saccharoid fraction shows changes similar to those in the accounted-for saccharoid fraction, in the diabetic rats, as was also the case after treatment with insulin of normal or diabetic animals. The fraction not accounted for by the estimated constituents may represent the reducing sugar phosphates present in the blood.

    Abstract: A field experiment was conducted at the central research farm of Bangladesh Agricultural Research Institute, Gazipur for two consecutive years to verify the yield response of wheat variety Prodip to different doses and split applications of N fertilizer to determine appropriate N dose and application method for increasing NUE and grain yield of wheat. The treatments comprised of 12 combinations of three doses of nitrogen (80, 100, and 120 kg/ha) from urea, which were assigned in the main plots and four methods of N splitting viz., application of all N as basal; 2/3rd basal plus 1/3rd as top dress at crown root initiation (CR1) stage; 1/2 basal plus 1/2 as top dress at CR1 stage; and 1/3rd basal with 1/3rd as top dress at CR1 plus 1/3rd as top dress at 1st node stage which were tested in the sub plots. Higher yield was achieved from N rate of 120 kgiha applied as three equal splits of one-third as basal during final land preparation, one-third as top dressing during CR1 and the rest one-third top dressing at first node stage. The yield advantage of wheat due to N treatments was attributed to higher thousand grain weight and spikes/m2. Nitrogen content in wheat grain and straw was not affected significantly by different N treatment and their combinations, whereas plant N uptake was significantly influenced by N rate and N splitting and also due to the interaction of N rate and N splitting. Total N uptake was maximum under N rate of 120 kg/ha applied as three equal splits as 1/3rd basal with 1/3rd as top dress at CR1 plus 1/3rd as top dress at 1st node stage. Split applications of sub-optimal dose of N (80 kg/ha) resulted in negative gain in apparent NUE, but split applications, especially three split applications (1/3rd basal, 1/3rd at CR1, and 1/3rd at 1st node stage) of higher dose of N (100 and 120 kg/ha) resulted in positive gain in apparent NUE.

    Abstract: The field experiment was conducted at the Hill Agricultural Research Station, BARI, Khagrachari for the two consecutive years (2009-10 and 2010-11) to find out the wheat variety suitable for hilly environment and investigate the interaction of sowing dates and varieties to recommend the promising variety with proper sowing time. The experiment was laid out in split-plot design with three replications where three dates of sowing (Nov. 20, Nov. 30 and Dec. 10) were assigned in the main plots and five modern wheat varieties (Shatabdi, Sufi, Sourav, Bijoy and Prodip) were tested in the sub-plots. The yield responses of wheat varieties during the two years showed that there were significant varietal differences under the experimental soil and environmental conditions. The variety Bijoy gave maximum grain yield closely followed by Sourav in both years. Shatabdi produced higher yield under early sowing (Nov. 20) but yield was decreased due to late sowing (Dec. 10). Initially the plant population and finally spikes/m2 were affected by late sowing that caused less yield in Shatabdi. The mean yield of all varieties pulled over the sowing time indicated that wheat yield was not affected due to delay sowing up to 10th December. The experimental result demonstrated that Shatabdi could be recommended only for early sowing whereas Bijoy and Sourav could be recommended both for early and late sowing under the experimental soil and environmental conditions at hilly region of Khagrachari.Bangladesh J.

    In: Bangladesh Journal of Scientific and Industrial Research, Bangladesh Academy of Sciences, Vol. 42, No. 2 ( 1970-01-01), p. 175-186
    Abstract: The study was aimed at determining the effect of sulphur and Bradyrhizobium fertilized seed at different initial moisture content of seed and storage container, to improving the germination percentage of groundnut seed. The germination test was carried out after storing the seed for five months. Results revealed that seeds obtained from 60kg S/ha. stored in polythene bags retained the germination percentage up to the standard level of ISTA for 5 months efficiently. Least initial moisture content of seed (7.25 %) produced from the above doses of fertilizer elements also played a vital role in keeping the quality of stored seed. Results in the respect of storage performance in terms of percentage of germination indicated that groundnut seed obtained from sulphur and Bradyrhizobium fertilizer elements during production and stored in polythene bag can retain better seed quality, provided seed were dried to a safe moisture level of 7.25 % to 8.46 %.
