Title: Calcium carbonate supplementation causes preventive approach to toxic effects of mercuric chloride on metabolic regulation in liver of C. punctata
Authors: Haque, M. S., Hasan, M. M. & Hossain, M. M.
Abstract: Mercury (Hg) shows the toxic effects in the environment although the etiology is not well characterized and the prevention of toxic effects induced by Hg is an important aspect of metabolic regulation in organisms. Channa punctata, a variety of species of fish was used in this study and the role of calcium carbonate on cholesterol, triglyceride and protein level in liver induced by HgCl2 was adopted. Fish were exposed to 1 and 10 µM of HgCl2 for 1h and cholesterol and triglyceride levels in excised liver were enhanced in response to HgCl2 when compared to respective controls however the effects were more pronounced for 1 µM concentration. Similar stimulatory effects on protein contents were demonstrated whenever they were exposed to HgCl2 (1 and 10 µM) and higher proteins were recorded for 10 µM concentration. The results indicate that HgCl2 causes severe toxic effects enhancing the above parameters. To clarify the role of CaCO3 on prevention of these effects, fish were treated with different concentrations (100 µM and 1 mM) of CaCO3 and CaCO3 + HgCl2. Cholesterol and triglyceride in liver were effectively reduced with CaCO3 (1 mM) + HgCl2 (10 µM) and CaCO3 (100 µM) + HgCl2 (1 µM) while 100 µM of CaCO3 potentially reduced the effects of HgCl2. Although CaCO3 was shown to reduce protein content effectively, however 100 µM concentrations have been found to inhibit the effects of HgCl2 preferentially. Our findings suggest that calcium carbonate might be involved in prevention of the toxic effects of Hg and may contribute to the survival process of this species.

Abstract: This research work was done under public private partnership approach to reduce the tray consumption, increase the field capacity of mechanical transplanter and provide suggestion for wide scale adoption of mechanical transplanting. A 6-row ride on transplanter was used to carry out this research at Hatgobindapur, Chandpur in Natore district during aman 2014 season. This machine has ten seedling density setting, four depth controls and four space setting options. Data were collected from 149 plots covering 10.64 ha. It was observed that field capacity of the transplanter depended on plot to plot distance, plot size, seedling tray supply and number of plots under transplanting activity. Fuel consumption was obtained 19.28 litre per hectare. Results revealed that almost 92% trays were required in mechanical tansplanting, 2% for gap filling and 6% in pocket area filling by manual labour due to irregular shape of the plot. Throughout the operations, 52% time was spent in plot to plot movement and as idle time. One extra skilled labour was needed to load and unload the tray in the machine. Among the transplanting plots, 70% were uniform, 25% were irregular and 5% were mostly irregular. Irregular and mostly irregular plots should be avoided to increase effective field capacity of the transplanter. During study period, 25% trays were saved after providing technical support. Effectiveness of the transplanter was proposed to improve the business opportunity of mechanical transplanter in the fragmented land holding system. Calibration should be done on space and seedling density setting based on soil condition, soil type, seedling height, seedling density before operation in each plot to get optimum plant spacing and number of seedling dispensed in each stroke. Operator should keep the record of tray requirement in each plot and close contact with the help of a monitoring officer. Seedling tray requirement in each plot can be reduced by adjusting plant to plant spacing and seedling density setting. Smaller plot should be avoided to increase the daily area coverage of the transplanter.
Key words: Rice transplanter, tray requirement, field capacity, missing hill and fuel consumption.

Title: Effects of foliar application of zinc and boron on growth and yield of summer tomato
Authors: Ali, M. R., Mehraj, H. & Jamal Uddin, A. F. M. (2015)
Abstract: To increase the yield of BARI hybrid tomato 4, cultivated in summer season of Bangladesh, foliar application of zinc and boron [T0: control; T1: 25-ppm ZnSO4 (Zinc Sulphate); T2: 25-ppm H3BO3 (Boric Acid) and T3: 12.5-ppm ZnSO4 + 12.5-ppm H3BO3] was done. Maximum plant height (106.9 cm), number of leaves (68.9/plant), leaf area (48.2 cm2), number of branches (11.9/plant), number of clusters (21.6/plant), number of fruits (1.8/clusters and 33.6/plant), fruit length (5.3 cm), fruit diameter (5.1 cm), single fruit weight (60.4 g) and yield (1.9 kg/plant, 25.7 kg/plot and 58.3 t/ha) were found from foliar application of 12.5-ppm ZnSO4 + 12.5-ppm H3BO3 while minimum from control. Early flowering (49.3 days) and minimum diseased infested plant (9.4%) were also found from foliar application of 12.5-ppm ZnSO4 + 12.5-ppm H3BO3.Combined foliar application of zinc and boron was more effective than the individual application of zinc or boron on growth and yield for summer season tomato (BARI hybrid tomato 4).

Title: In vitro callus induction and plantlet regeneration is influenced by the maturity status of embryos of Brassica rapa varieties
Authors: Zisan, S., Robin, A. H. K., Hoque, A. & Hossain, M. R. (2015)
Abstract: Brassica rapa (AA, 2n = 20) is a prime oilseed species in Bangladesh that can be improved via biotechnological approaches. Rescue of developing embryos after an interspecific hybridization, which otherwise usually tend to abort, is very important for improvement of this species, that require an efficient embryo culture protocol. The immature torpedo shaped embryos (451-700 µm) and mature walking-stick type (>700 µm) embryos of five B. rapa varieties namely, Safal, Agrani, BINA Sarisha-6, BARI Sarisha-6, BARI Sarisha-15 were cultured in basal MS media supplemented with 1 mgL-1 BAP, 0.5 mgL-1 NAA & 1 mgL- 1 2,4-D. The immature embryo culture followed indirect somatic embryogenesis process but the mature embryos followed direct organogenesis. The immature embryos induced callus within 11-15 days whereas the mature embryos regenerated plantlets through direct organogenesis within 8-11 days. The varieties Agrani, BARI Sarisha-6 and BINA Sarisha-6 induced the highest percentages of callus from immature embryos and the varieties Safal and BARI Sarisha-15 regenerated the highest percentage of plantlet from mature embryos. Safal and Agrani induced callus and regenerated plantlets comparatively earlier than other varieties. An increase in the concentration of BAP from 10 to 20 ppm in MS media + 5 ppm IBA decreased the size of the plantlets of all varieties except the Agrani. The data could be used in improving the existing embryo rescue protocols. The direct organogenesis process of mature embryos can potentially shorten the breeding cycles.

Title: RAPD analysis of phomopsis fruit rot resistance in eggplant advanced lines
Authors: Bilkiss, M., Akhter, R., Islam, M. M., Khalil, M. I. & Meah, M. B. (2016)
Abstract: Ten lines of eggplant (F3 to F7) derived from the crossing BAU Begun-1(resistant variety) with Dohazari G and Laffa S (susceptible cultivars) were evaluated for disease resistance and genotypic performances. Two lines of different characters from each generations were selected and inoculated with Phomopsis vexans under confined field condition at fruiting stage. The inoculated genotypes exhibited differential disease reaction. Per-cent fruit infection ranged from 2.77% to 4.1%. All the lines were found to be resistant to phomopsis fruit rot indicating the inheritance of resistance trait of donor parent BAU begun-1 to the offspring. Random Amplified Polymorphic DNA (RAPD) technique was used as a tool for assessing genetic variation and relationships among the genotypes. Amplification with three decamer primers generated 13 bands of which 11 (84.62%) were polymorphic. The highest intra-variety similarity indices (Si) value was found for Laffa purple globose of F7 plants and Dohazari green long of F4. The coefficient of gene differentiation (Gst) was 1.00 reflecting the existence of high level of genetic variations among the genotypes. Comparatively higher genetic distance (0.7466) was observed between Dohazari green long of F6 vs Laffa green globose of F6 and the higher genetic identity (0.9870) was found in Dohazari green long of F6 vs Laffa green globose of F5. The dendrogram (UPGMA) constructed from Nei’s genetic distance produced two main clusters of the ten genotypes. The advanced lines can be released as variety after yield trial and also the genetic variation and relatedness to disease reaction as assessed using RAPD marker could be potential sources for further development of P. vexans resistant variety in terms of fruit color and shape.

Abstract: This study provided information on housing, feeds and feeding management, mating system and healthcare management of Black Bengal goats at rural villages of Mymensingh sadar upazila under Mymensingh district in Bangladesh. All farmers reared goats in semi-intensive system and most of them had goat house, provided bedding materials at winter season. Most of the farmers took bath of their goats at summer but a few of them did the same in winter season. Most of the farmers used concentrate feed with green grass and supplied water once in a day in particular waterer. Major sources of drinking water for goats were tube well and during rainy season most of the farmers grazed their goats. Farmers supplied little bit more grass and tree leaves to their lactating does than that of pregnant does while they supplied more amount of concentrates feed to their pregnant does than that of lactating does. Birth and weaning weight were higher in male kids than female kids. Few farmers vaccinated their goats. Farmers did not keep breeding buck and they did not use artificial insemination (AI) for their does. Spouses were the main contributor in goat keeping. Above discussions might be indicative that farmers were more careful about housing, feeding but less careful about health care and breeding buck keeping issues.
Key words: Black Bengal goat, feeds and feeding and breeding buck keeping

Title: Yield of rice in response of shade and orientation
Authors: Shammi, R., Abdullah, M. R. & Rahman, M. M. (2016)
Abstract: To find out shading effect of some selected tree species and different orientations on the yield and yield attributes of rice cv BR11 in agro forestry system an experiment was laid out in two factorial, Randomized Complete Block Design with three replications. Rice was grown in different orientations around the tree of Albida, Akashmoni and Jhau (North, South, East and West orientations), as the orientations were made 1 m apart from the tree base. The effect of tree-rice association was found significant on plant height, effective tillers hill-1, non-effective tillers hill-1, effective grains panicle-1, sterile spikelets panicle-1, total grain (t ha-1) and straw yield (t ha-1). It was recorded that out of the three tree-rice association, the highest yield (4.88 t ha-1) was found under Albida and the lowest yield (4.70 t ha-1) was found under Akashmoni that was statistically similar with Jhau. The highest (7.10 t ha-1) and lowest (6.80 t ha-1) straw yield were found under Albida and Akashmoni. The highest plant height (105.75 cm), effective tillers hill-1 (11.85), non-effective tillers hill-1 (1.91), effective grains panicle-1 (140.65), and sterile spikelet panicle-1 (29.88) were found under the Albida. Regarding different orientations from the tree base, the plant height, effective tillers hill-1, non-effective tillers hill-1, effective grains panicle-1 and grain yield (t ha-1) of rice were significant. The highest grain yield (4.86 t ha-1) of rice was obtained at the north orientation and the lowest grain yield (4.60 t ha-1) of rice was obtained at the west orientation, while significantly highest grain yield (5.00 t ha-1) was found in control. All parameters produced the highest performance in open field compared to tree-rice association in respect of orientation.

Abstract: The study was conducted to assess the influence of BAP and NAA on in vitro plantlet regeneration of local and exotic banana cultivars. Shoot tip of the cultivars Grand Naine, Amritasagar and Sabri were used as explants for establishment of culture. Different concentrations of BAP (1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 mg/L) were used in MS medium to study their effects on shoot formation. Explants of all the cultivars produced both single and multiple shoots but rate of shoot regeneration varied among different cultivars and BAP concentrations. The highest shoot regeneration was found in all the three cultivars at 5.0 mg/L of BAP. Among the three banana cultivars Grand Naine produced the highest shoot. Shoot proliferation rate of Grand Naine, Amritasagar and Sabri was 3.50, 3.25 and 1.75 (per explant) respectively was obtained after 30 days of culture. MS medium supplemented with different concentrations of NAA (0.5, 1.0, 2.0, 4.0 and 6.0 mg/L) were used for in vitro root formation from proliferated shoots. The cultivars Grand Naine showed the best root forming performance in all concentrations of NAA. Best results of root formation were observed on MS medium supplemented with 4.0 mg/L NAA. All the plantlets regenerated in vitro from shoot tip explants of three banana cultivars survived in the field condition but Grand Naine showed the superior performance.

Authors: Islam, S. A., Miah, M. A. Q., Habib, M. A. & Alam, M. M. (2016)
Abstract: Growth trials of Sonneratia apetala (keora) raised from three different seed sources were conducted in the newly accreted lands at Rangabali under Patuakhali and Char Kukri-Mukri under Bhola district to assess the variation of growth and wood production of the species planted in 2007 and 2009. Data on survival, tree height and diameter at breast height (dbh) were recorded from 7 and 5 years old two trial plantations. Significantly greater height of 12.54m and 12.09m and greater dbh of 15.58cm and 14.56cm were recorded for best trees seed source at Char Kukri-Mukri and Rangabali sites respectively at the age of 7 years. Similarly, significantly greater height of 11.88m and 11.57m and greater dbh of 14.55cm and 13.44cm were recorded for best trees seed source at the age of 5 years in Char Kukri-Mukri and Rangabali sites respectively. Significantly greater wood volumes of 38.09 m3/ha/year and 37.50 m3/ha/year were produced by plantations of best trees seed source in both Char Kukri-Mukri and Rangabali sites respectively at the age of 7 years. The lowest growth and wood production were shown in the plantations raised from seeds of mass collection in both the years. Therefore, large scale plantations of S. apetala can be raised by using seedlings of best trees seeds for obtaining maximum growth and yield of coastal mangrove forest.

Authors: Haider, M. R., Alam, M. S. & Anita, R. S. (2016)
Abstract: Germination behavior of Sapindus mukorossi Gaertn. under six different pre-sowing treatments and seedling growth performance in nursery and field conditions were investigated. The treatments were i) soaked in hot water (1000C) for 10 second, ii) soaked in cold water for 12 hours, iii) soaked in cold water for 24 hours, iv) soaked in cold water for 36 hours, v) seeds scratched on the cemented floor and vi) control. Growth performances were determined by transferring the young seedling having 4-6 leaves at the age of 25-30 days, from germination bed to polybag filled with soil-cow dung mixture and followed by outplanting in the field at one year age. Germination percentage was significantly (p ≤ 0.05) enhance by pre-sowing treatment in hot water (1000C) for 10 seconds in comparison to other treatments. The survival percentage of seedling was highest (89%) in the field after one year at 2.0 m x 2.0 m spacing and average height was 94.32 cm after 2 years of outplanting. Pre-sowing treatment of seeds in hot water (1000C) for 10 second for nursery raising and one year old seedlings for outplanting at 2.0 m x 2.0 m spacing in the field were found suitable for successful plantation for the species.
