  • Polythene Mulch and Irrigation for Mitigation of Salinity Effects on Maize
           (Zea mays L.)

    • Authors: M U Sikder, M Asadul Haque, R Jodder, T Kumar, D Mondal
      Pages: 1 - 13
      Abstract: A pot experiment was conducted at the net house of Patuakhali Science and Technology University during rabi season 2014-15 to estimate the contribution of polythene mulch and irrigation on reducing of salinity effect on maize (Zea  mays L.). The experiment was laid out in a three factors randomized complete block design with three replications. The factors were salinity (two levels: without and 5 dS/m salinity), mulch (two levels: without and with polythene mulch) and irrigation (three levels: 125, 250 and 500 ml water/irrigation). BARI hybrid maize-7 was the test crop. Every pot received the same amount of fertilizer nutrients. Crops were harvested at tassel initiation stage. Mulch increased soil temperature by 2 to 4.5°C (with average of 3.1°C) over without mulch. In without mulch condition, salinity reduced shoot fresh and dry, and root fresh and dry weight by 28.3, 10.3, 39.4 and 30.6%, respectively. In with mulch condition, however, these reductions were 1.0, 7.2, 12.3 and 12.1 %, respectively. Polythene mulch reduced salinity induced reduction of the above parameters by 96.5, 30.1, 68.8 and 60.5 %, respectively. Under 125, 250 and 500 ml water/irrigation treatment, salinity reduced shoot fresh weight by 14.2, 19.3 and 6.7 %, respectively; shoot dry weight by 15.4, 6.6 and 5.0 %, respectively; and root fresh weight by 27.5, 20 and 11.6 %, respectively. Thus, the effect of salinity in maize was gradually decreased with the increasing amounts of irrigation water. Soil salinity reduced phosphorus and increased sulphur content in maize plants.The Agriculturists 2016; 14(2) 01-13

  • Determination of Crop Co-efficient Values of Soybean (Glycine max [L.]
           Merrill) by Lysimeter Study

    • Authors: A J Mila, A R Akanda, K K Sark
      Pages: 14 - 23
      Abstract: Local level calibration of crop coefficient (Kc) values is critical for regional level planning and allocation of water resources for irrigation. In this regard, an experiment was conducted at the Irrigation and Water Management Division of Bangladesh Agricultural Research Institute (BARI), Gazipur, in order to estimate crop coefficient values of soybean under the local climatic condition. An improved crop variety- BARI Soybean-6 was used in this experiment. The crop was grown under four irrigation treatments, allowing irrigation at an interval of 10, 15, 20 and 25 days. The treatments were so designed that drainage was allowed between the consecutive irrigations. Irrigation at 15 days interval produced the highest seed yield of 1.26 t/ha and was considered to be suitable for estimating seasonal crop evapotranspiration (ETc) and Kc values. The seasonal highest cumulative ETc was 308.43 mm under this treatment. The Kc values of soybean at initial, development, mid-season and late season stages were found as 0.67, 1.46, 1.59 and 0.62, respectively.The Agriculturists 2016; 14(2) 14-23

  • In vitro Regeneration and Rapid Multiplication of Dendrobium bensoniae, an
           Indigenous Ornamental Orchid

    • Authors: S S Riva, A Islam, M E Hoque
      Pages: 24 - 31
      Abstract: An experiment was conducted on in vitro regeneration and multiplication of Dendrobium bensoniae. Different concentrations of BA and IBA alone or combination of both hormones were used as treatment for regeneration.  It was revealed that shoot regeneration from node was the best at 2.0 mg/l BA supplemented to MS medium. It gave better responses than all other concentrations and combinations of BA and BA+IBA, used in the present study. The highest number of shoots and leaves were found when 1.0 mg/l BA with 1.5 mg/l IBA was supplemented into MS medium.  For rooting, 0.5 mg/l BA with 1.0 mg/l IBA was found to be the most effective. The well-rooted plantlets were successfully acclimatized under 70-80% humidity and planted in pots and transferred to the shade house for establishment. Around 85% of plantlets survived in the field. From the present result, it may be recommended that MS medium supplemented with 2.0 mg/l BA may be used for rapid shoot induction and regeneration of D. bensoniae.The Agriculturists 2016; 14(2) 24-31

  • Financial Analysis of Litchi (Litchi chinensis Sonn.) Production in
           Dinajpur District of Bangladesh

    • Authors: Rumana Akter, M Serajul Islam, Golam Rabbani
      Pages: 32 - 37
      Abstract: The present study was conducted in 2015 to examine the profitability of litchi orchard production at Dinajpur sadar upzila in Dinajpur district where litchi orchards are generally leases out for 1 to 6 years by the owners known as “Deed”. In total 312 litchi orchard trees of which 254 were Bombai, 40 Madrazi, 20 China-3, 2 China-2 and 3 were Bedana, were selected to estimate the BCR, NVP and IRR of litchi production. The litchi trees were 18 to 22 years old. Project appraisal techniques and sensitivity analysis was done by using primary data to determine cost and benefits from litchi production. The study revealed that individual’s investment on litchi production is profitable. The study also found that in producing litchi Benefit Cost Ratio (BCR), Net Present Value (NPV) and Internal Rate of Return (IRR) were 1.93, Tk. 1643896 and Tk. 1230, respectively. Sensitivity analysis suggested that the investment in litchi production is profitable even for 10% increase in operating and maintenance cost or 10% decrease in gross benefit.The Agriculturists 2016; 14(2) 32-37

    • Authors: M S Ahmed, Afroza Begum, M A Rahman, M W Akon, M A Z Chowdhury
      Pages: 38 - 47
      Abstract: The study was carried out to detect and quantify the left over residues of eight commonly used insecticides (fenvalerate, diazinon, quinalphos, fenitrothion, acephate, chlorpyriphos, cypermethrin and malathion) in brinjal, yard long bean, bitter gourd, snake gourd, pointed gourd, okra, tomato, hyacinth bean and cabbage samples collected from local market of eight different regions like Jessore, Comilla, Narsingdi, Tangail, Rangpur, Jamalpur, Gazipur and Dhaka during 2011-2012 seasons. Among the170 analyzed samples, 21.78% were contaminated with four insecticides (chlorpyriphos, quinalphos, acephate and cypermethrin) either single or multiple product residue, in which 18.26% samples had residue above MRL. The vegetables of Norsingdi, Jessore and Comilla had more insecticide residue in comparison to other locations. Most of the samples contain chlorpyriphos (13.53%) and quinalphos (8.4%) residue. Acephate, chlorpyriphos and quinaphos were also found as multiple product residues expressing 2.35% of the total samples which were above MRL and 19.41% sample contained single product residue with chlorpyriphos, quinaphos and cypermethrin where 15.88% were of above MRL. Cypermethrin residue was detected only in two samples (brinjal and yard long bean) which were below MRL.The Agriculturists 2016; 14(2) 38-47

  • Response of Medium and Long Duration Boro Rice Variety (Oryza sativa L.)
           to Nitrogen Fertilizer

    • Authors: Amina Khatun, M K Quais, A A Begum, M A Saleque, M S U Bhuiya
      Pages: 48 - 60
      Abstract: A field experiment was conducted during November 2009-April 2010 in Bangladesh Rice Research Institute, Bangladesh to examine the response of two rice (Oryza sativa L.) varieties (BRRIdhan28 and BRRI dhan29) to six N rates of nitrogen fertilizer viz. 0, 50, 100, 150, 200 and 250 kg ha-1. The experiment was conducted in a RCB design with three replications. Grain yields of both BRRI dhan28 and BRRI dhan29 increased significantly in a quadratic fashion with N rates. The highest grain yields were obtained from 150 kg N ha-1 in both the varieties. More than 1 t ha-1 yield was obtained in BRRI dhan29 (6.34 t ha-1) at the same rate of N indicated BRRI dhan29 as a nitrogen efficient variety. However, the predicted economic optimum doses of N appeared to be 156 and 158 kg ha-1 for BRRI dhan28 and BRRI dhan29, respectively. The grain yield was mainly influenced by the number of panicles per hill, which was found to increase with the increase of N rates in both the varieties.

    • Authors: Baadruzzoha Sarker, Mustafizur Rahman, Md Ruhul Amin
      Pages: 61 - 66
      Abstract: An experiment was carried out to study the density dependent growth of silver barb   (Barbonymus gonionotus) for a period of 2 months during14 March to 18 May, 2013 in ponds with individual water area of 2.0 decimal. The experiment was conducted with three treatments, replicated three times, where stocking densities were 50, 100 and 150 fish/decimal in T1, T2 and T3, respectively. Feeds were supplied twice daily throughout the study period. Sampling was done at weekly interval throughout the experimental period. Water quality parameters were monitored weekly. Temperature ranged from 26.40 to 30.13°C, transparency from 32.36 to 46.23 cm, dissolved oxygen from 4.80 to 5.83 mg/l and pH from 6.68 to 8.11. During the study period, growth parameters were analyzed. The mean weight gains were 52.48, 49.98 and 47.87 g, the percent weight gains were 2560.16, 2438.37 and 2335.12, the average daily weight gains were 0.82, 0.78 and 0.74 g, the specific growth rates were 5.12, 5.05 and 4.98%, the survival rates were 89.6, 86.67 and 82.11% in T1, T2, and T3, respectively. There were significant differences among T1, T2 and T3 for all the growth parameters. The total productions of silver barb were 603.85, 1114.00 and 1518.06 kg/ha/2 months in T1, T2 and T3, respectively. The present study indicates that the growth of silver barb was density dependent when grown in monoculture systems and the best stocking density for production was 150 fish/decimal. The Agriculturists 2016; 14(2) 61-66

    • Authors: Md Shariful Islam, M Obaidul Islam
      Pages: 67 - 76
      Abstract: The experiment was carried out at the Bangladesh Sugarcane Research Institute (BSRI) farm at Ishurdi, Pabna, Bangladesh during2008-2009 and 2009-2010to investigate the growth and yield of main crop sugarcane, and companion crops potato and mungbean as successive intercrops. Row to row spacing (RRS) of sugarcane were 80 (S1), 100 (S2) and 120 cm (S3) and sugarcane was intercropped with 1, 2 and 3 rows of potato as 1st intercrop and followed by mungbean with same row ratio as 2nd intercrop. Sugarcane and companion crops potato and mungbean were cultivated following the cultivation methods of BSRI and Bangladesh Agricultural Research Institute (BARI), respectively. To provide more light to intercrops bended leaves of sugarcane on both sides of rows were cut at middle and compared with non-cutting of leaves in respect of growth and yield of main crop and intercrops as well. The total dry matter production, cane yield and sugar yield were the highest at 120 cm RRS of sugarcane (non-leaf cutting=C0) intercropped with 3 rows of potato followed by 3 rows of mungbean (S3C0). The number of tiller and millable canes, and leaf area index (LAI) were the highest at 80 cm RRS of sugarcane (C0) with one row of potato and one row of mungbean (S1C0). The effect of light interception on growth and yield of first intercrop (potato) was insignificant whereas it was significant for second intercrop. Yield of mungbean (2nd intercrop) and light interception ratio (%) was the lowest in S3C1 where sugarcane RRS was 120 cm + 3 R potato followed by 3 R mungbean with leaf cutting (LC). The results of the experiment indicated that sugarcane transplanted at RRS of 120 cm with 3 rows of potato followed by 3 rows of mungbean can be grown as intercrops for increased yield of sugarcane as well as for increased cropping intensity and might be recommended for farmers practice in High Ganges River Flood Plain soils under AEZ 11 of Bangladesh.

      Pages: 77 - 85
      Abstract: The experiment was conducted to determine the effect of irrigations and sowing dates on growth and yield performance of wheat in the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of November 18, 2012 to March 30, 2013. The experiment was comprised of two factors, viz. factor A: two irrigations namely irrigation (I) and no irrigation i.e. control (I0), and factor B: three sowing dates such as S1: 1st sowing on 18 November, S2: 2nd sowing on 03 December and S3: 3rd sowing on 18 December. The experiment was laid out in a split plot design with three replications. Irrigation was assigned in the main plot, while sowing time was in the sub-plots. Data on grain yield and different yield contributing characters were taken after harvest. Results indicated that the highest grain yield was obtained with I (2.915 t ha-1) and S1 (2.983 t ha-1). The interaction of irrigation (I) and sowing on 18 November (S1) showed the maximum yield (3.387t ha-1), spike length (17.08 cm), 1000 grain weight (43.4 g), spikelets spike-1 (20.03) and grain spike-1 (65.58) of wheat.The Agriculturists 2016; 14(2) 77-85

    • Authors: Shah Mohammad Keramat Ali, Salamat Khandker, Joti Lal Barua, A H M Jalal Uddin Akbar, Md Mahfuz Ali
      Pages: 86 - 94
      Abstract: This study was conducted to draw linkage between intake pattern of Choline and nutritional status of pregnant women in 3rd trimester and assess the contribution of agriculture retrospectively to increase its intake. Retrospective data was therefore, collected from United States Development Agency (USDA) data base on Choline content of common vegetable products of Bangladesh. Recommended Choline intake for the pregnant women in 3rd trimester is 450mg/day. The present study conducted using 24 hours recall method revealed that average Choline intake among the study respondents was 317 mg/day which meet 71 percent of the requirement. Majority (72.7%) of the women took Choline below the recommended level (450 mg/day). It is remarkable that 56.7, 55.3 and 52.0% of the pregnant women were deficient in calorie, protein and fat intake respectively. This study found that 54% respondents’ mothers were within normal Body Mass Index (BMI) while 33% were overweight, 5.3% were underweight and 8.0% were obese. Choline intake status was poor among the pregnant women commencing delivery complication and indicating high prevalence of mental retardation for newborn.The Agriculturists 2016; 14(2) 86-94

  • Effect of Urea Super Granule and Prilled Urea on Yield and Yield
           Attributes of Broccoli (Brassica oleracea var. italica L.)

    • Authors: M J Hussain, A J M S Karim, A R M Solaiman, M S Islam, M Rahman
      Pages: 95 - 112
      Abstract: A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during 2010-2011 to determine the effects and economic performance of urea super granule (USG) and prilled urea (PU) in terms of growth and yield of broccoli and to find out the optimum and economic doses of USG and PU for broccoli in Shallow Red-Brown Terrace Soil under Madhupur Tract. The experiment was laid out in a randomized complete block design with three replications having 17 treatment combinations constituted with different levels of urea super granule (USG) and prilled urea (PU). Result showed that yield of broccoli increased significantly with increasing rate of USG and PU. The treatments containing 160 kg N from USG and 180 kg N from PU exhibited the best performance on yield and yield contributing characters of broccoli having the head yield of 12.9 and 10.6 ton ha-1, respectively. All the yield contributing characters and the economic profitability were favorably correlated with these high yield performing treatments. The performance of USG in terms of growth, yield and yield attributes, head quality (compactness coefficient) and economic profitability was found significantly higher as compared to that of PU. Therefore, USG @ 160 kg N ha-1 and PU @ 180 kg N ha-1 alongwith other recommended fertilizerscould be suggested for broccoli production in terms of yield and economics. From quadratic equation USG @ 163 and 160 kg N ha-1 and PU @ 169 and 160 kg N ha-1 alongwith other recommended fertilizerscould be suggested as optimum and economic doses for broccoli production in Silty Clay Loam Soil of Madhupur Tract.The Agriculturists 2016; 14(2) 95-112

  • Climate Change Vulnerabilities of Woman in Bangladesh

    • Authors: Nishith Zahan Tanny, M Wakilur Rahman
      Pages: 113 - 123
      Abstract: This paper reviews the existing literature on gender differentiated climate change vulnerabilities in developing countries including Bangladesh. It is evident that climate change amplifies the vulnerabilities of poor people who are marginalized and more dependent on the threatened natural resources. Among the poor people women are seemed to be disproportionately affected by climate change. The review took utmost effort to unfold the root causes of gender differentiation under climate change scenario. It identifies some governing factors such as ownership, political affiliation, labor force participation that determine the extent of the effect of climate change. Deeper analyses of the literatures indicate that ‘gender differentiated impacts’- are directly related to traditional gender roles of women. It also reveals the constraints to women’s adaptation resulting from access to resource allocation and other elements of society. Drawing lessons from the existing literatures, finally it outlines some of the policy options to ensure the inclusion of women in development arena.The Agriculturists 2016; 14(2) 113-123

  • Effect of Indole Butyric Acid on Raising Plants from Stem Cuttings of Tea
           (Camellia sinensis L.) in The Nursery

    • Authors: Mohammed Enamul Hoque
      Pages: 124 - 129
      Abstract: A field experiment was conducted at the central nursery of tea extension center of Bangladesh Tea Board in Bandarban during September to November, 2015 to determine the precise concentration of Indole Butyric Acid (IBA) on propagation through stem cuttings of tea. The experiment was laid out in a randomized block design with four treatments of IBA concentrations: 0 ppm (Control), 2000 ppm, 4000 ppm and 6000 ppm and each treatment was replicated four times. Basal part of tea (BT-2 variety) cuttings were dipped in different IBA concentrations for five seconds. Then these cuttings were dibbled into prepared soil mixture as rooting media. Cuttings were exposed to the rooting media for 90 days and then they all were removed carefully to assess the variation of establishment of cuttings. IBA treated cuttings showed better effect on the rooting rate, root length, root number, shoot length and survival rate compared to the control. It was noted that cuttings treated with 4000 ppm IBA produced the highest rooting rate 79.85%, the highest survival rate 57.60% and the highest root length of 4.85 cm followed by treatment 6000 ppm IBA. In case of all parameters, effects of the treatments 4000 ppm and 6000 ppm of IBA were statistically similar. Positive and strong correlation was observed both in rooting rate versus survival rate and root length versus shoot length in IBA treated cuttings. Thus, IBA at 4000 ppm concentration was recommended for establishment of stem cuttings of tea (BT-2 variety) in the nursery.The Agriculturists 2016; 14(2) 124-129
