  • Callus Derived Regeneration of Some Selected Brassica Genotypes

    • Authors: S K Biswas, M Z Tareq, S Ahmmed, A B M Z Hoque, M T Rahman
      Pages: 1 - 10
      Abstract: The experiment was conducted to observe the callus induction ability of Brassica species. Plantlets were regenerated from cotyledon and stem explants of Brassica napus, Brassica campestris and Brassica juncea through direct organogenesis. The experiments were conducted in a Completely Randomized Design (CRD) with 4 replications. The highest frequency of callus formation was recorded in MS containing 2.0 mgl-1 BAP, 0.5 mgl-1 NAA and 2.0 mgl-1 AgNO3 in both stem and cotyledon explants. Among these explants, stem was found to be better responsive in callus induction than cotyledon. Among the genotypes used, BINA Sarisha-4 induced the highest percentage (100.00%) of callus from stem explants which was followed by BINA Sarisha-5 (100.00%) and Sampad (83.35%). On the other hand, BINA Sarisha-4 induced callus from 91.67% cotyledon explants, followed by BINA Sarisha-5 (75.00%) and Sampad (66.67%). Similarly, the highest percentage of shoot regeneration (58.34%) from stem explants of BINA Sarisha-4 was observed in MS medium supplemented with combination of hormone and silver nitrate concentrations. The highest percentage of root induction was 66.67 and 58.33% in plantlets derived from stem and cotyledon explants, respectively in ½ MS medium supplemented with 2.0 mgl-1 IBA and 0.5 mgl-1 of NAA. The highest survival rate was found after acclimatization of plants derived from stem (77.78%) and cotyledon (64.28%) explants of BINA Sarisha-4 in pot and 64.33 and 55.55%, respectively in field.The Agriculturists 2017; 15(2) 01-10

  • Economic Impact of Practicing IPM Technology on Bitter Gourd (Momordica
           charantia L.) Production in Comilla District of Bangladesh

    • Authors: S Islam, D M S Islam, R Khanum
      Pages: 11 - 23
      Abstract: The present study was conducted to assess the economic impact of practicing Integrated Pest Management technology on bitter gourd production in Chandina upazila under Comilla district of Bangladesh. Sample survey was carried out over 70 bitter gourd producing farms. Out of 70 farmers, 35 for IPM and 35 for Non-IPM farmers were selected. The study revealed that majority of the farmers had moderately favorable attitude towards IPM technology for producing bitter gourd as shown by farmers’ attitude index. IPM farmers earned more profit than Non-IPM farmers on bitter gourd production. The average total cost of bitter gourd production per hectare  was estimated at about Tk 3,68,335 and  4,44,508 for IPM and Non-IPM farmers, respectively. The average gross returns per hectare were found at about Tk 8,60,016; 8,55,642; and 8,15,947 for marginal, small and medium IPM farmers, respectively. The same were Tk 8,22,654; 7,53,373 and 7,48,255 for marginal, small, and medium Non-IPM farmers, respectively. The estimated BCR was higher for IPM farmers (2.29) than Non-IPM farmers (1.69). Partial budget analysis showed that IPM technology was more profitable and net benefit was Tk 1,61,557. Although bitter gourd production was profitable, farmers faced several problems such as lack of training and technical knowledge, inadequate extension services, lack of marketing facilities etc. in using IPM technology.The Agriculturists 2017; 15(2) 11-23

  • Effect of Different Levels of Urea Super Granule and Prilled Urea on the
           Crop Quality, Nutrient Uptake and Soil Nutrient Status of Broccoli

    • Authors: M J Hussain, A J M S Karim, A R M Solaiman, M S Islam, M Rahman
      Pages: 24 - 39
      Abstract: A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during the period 2010-2011 to assess the effect of urea super granule (USG) and prilled urea (PU) on the quality attributes (Compactness coefficient, Vitamin C, β-carotene and chlorophyll contents) of broccoli, to assess the comparative performance of USG and PU on nutrient uptake and uptake efficiency of broccoli plant, to assess the effect of different forms and levels of urea N on the post harvest soil nutrient status of broccoli field and to select the better doses of USG and PU for quality broccoli production in Shallow Red-Brown Terrace Soil under Madhupur Tract (AEZ-28). The experiment was laid out in a randomized complete block design with three replications having 17 treatments constituted with different levels of urea super granule (USG) and prilled urea (PU) as- T1: N-control,  T2: PU-N80, T3: PU-N100, T4: PU-N120, T5: PU-N140, T6: PU-N160, T7: PU-N180, T8: PU-N200, T9: PU-N220, T10: USG-N80, T11: USG-N100,  T12: USG-N120, T13: USG-N140, T14: USG-N160, T15: USG-N180, T16: USG-N200, T17 and USG-N220 kg ha-1. Results revealed that the comparative performance of USG in relation to head quality (compactness coefficient, ascorbic acid, β-carotene and chlorophyll content), nutrient (NPKS) uptake and N uptake efficiency was found better as compared to PU. The compactness coefficient, β-carotene and chlorophyll contents were increased with increasing rate of N as well as USG and PU, but ascorbic acid content was slightly decreased with increasing rate of USG and PU. The maximum compactness coefficient (18.61) was found from the treatment USG-N180 that was followed by USG-N160 (18.24) and the highest β-carotene content (0.401 mg/100gFW) was found from USG-N160 followed by PU-N180 (0.40 mg/100gFW). Similarly the highest chlorophyll-a content (0.818 mg/100gFW) was found from USG-N180 followed by USG-N160 (0.814 mg/100gFW) and the highest chlorophyll-b content (1.141mg/100g FW) was recorded from USG-N180. The higher nutrient uptake and N uptake efficiency (108.531%) was obtained from USG treated plots over that of the PU. But N uptake efficiency was decreased with increasing rates of N fertilizer. But post harvest soil nitrogen status did not show any systematic trend although it was found higher in USG over PU. Similarly no remarkable changes were observed in post harvest soil P, K, S and B status for the crop. However, USG @ 160 kg N ha-1 (USG-N160) followed by USG-N140 and PU @ 180 kg N ha-1 (PU-N180) with other recommended doses of fertilizer could be suggested as USG and PU based fertilizer recommendation for a good quality broccoli production in terms of yield and quality in Silty Clay Loam Soil of Madhupur Tract.The Agriculturists 2017; 15(2) 24-39

  • Leaf Characteristics and Yield Performance of Mungbean (Vigna radiata L.)
           Varieties under Different Levels of Shading

    • Authors: M A Hossain, M A Hasan, S Sikder, A K M M B Chowdhury
      Pages: 40 - 51
      Abstract: An experiment was carried out to evaluate the leaf characteristics and yield performances of mungbean (Vigna radiata L.) under different light levels at the Crop Physiology and Ecology Research Field of Hajee Mohammad Danesh Science and Technology University, Dinajpur during March to June 2016. The experiment was laid out in a split plot design with three replications. Three light levels (L100 - 100 % light intensity, L75- 75 % light intensity and L50- 50% light intensity) were assigned in the main plots and four varieties (BARl Mung-6, BINA Mung-8, BINA Mung-5 and BU Mug-4) were assigned in subplots. Mosquito nets of different pore size were used for maintaining 75 and 50 percent light intensity. Leaf area was increased due to reduced light levels in all mugbean varieties but the increment was significant in BINA Mung-5 and BINA Mung-8 only at 75% light intensity at 40 days after sowing and only in BARI Mung-6 with L50 and BU Mug-4 with L75 and L50at 50 days after sowing. Due to reduced light levels, leaf dry weight was affected more in BINA Mung-5 and BU Mug- 4 than BARI Mung-6 and BINA Mung-8. Leaf thickness was reduced under shade in all the mungbean varieties, except in BU Mug-4 at 75% light intensity, and the reduction in leaf thickness was mainly due to the reduction in thickness of spongy layer. The palisade layer thickness was influenced insignificantly but spongy layer thickness was increased in BINA Mung-5 at 100% light intensity. The grain yields (t ha-1) of BARI Mung-6 and BINA Mung-8 remained stable under partial shade condition but the grain yield of BINA Mung-5 and BU Mug-4 was reduced drastically under partial shade condition. Higher leaf dry weight, number of pods plant-1, seeds pod-1, and heavier grains in BARI Mung-6 and BINA Mung-8 contributed to the higher grain yield plant-1 under partial shade condition than in BINA Mung-5 and BU Mug-4.The Agriculturists 2017; 15(2) 40-51

  • Pre-Storage Fungicidal Treatment Effects on Prevalence of Seed-Borne Fungi
           and Quality of Onion (Allium cepa L.) Seed

    • Authors: A A Khan, K U Sarker, M F Hossain, M M Haque, I H Mian
      Pages: 52 - 58
      Abstract: Effect of pre-storage fungicidal treatment on prevalence of seed-borne fungi and quality of onion (Allium cepa L.) seeds was evaluated under laboratory condition. Seeds were treated separately with five fungicides namely Bavistin 50 WP (Carbendazim) and Dithane M-45 (Mancozeb) @ 2.2 g/kg, Homai (Thiophanate) and Rovral (Iprodione) @ 2.0 g/kg and Provax-200 (Carboxin) @ 3.0 g/kg of seeds before storage. Prevalence of seed-borne fungi, percent seeds germination and vigor index were evaluated just before storage, 75 and 150 days after storage. Fungicides produced significant negative impact on seed-borne fungi and positive impact in maintaining quality during storage. Provax-200, Rovral, Dithane M-45 and Bavistin effectively reduced seed-borne fungi and performed better for germination and vigor of seeds. Seed treatment with Provax-200, Rovral, Bavistin or Dithane M-45 would therefore be suggested as effective fungicides to control seed-borne fungal infection and maintain better germination and vigor of onion seed in storage.The Agriculturists 2017; 15(2) 52-58

  • Technical Efficiency of the Setbag Net Fishery in Bangladesh: An
           Application of a Stochastic Production Frontier Model

    • Authors: Md Golam Rabbani, Md Akhtaruzzaman Khan, M Serajul Islam, Rozina Yeasmin Lucky
      Pages: 59 - 65
      Abstract: A study was conducted to examine the technical efficiency for Setbag net fishing boats operated in the year 2014. A total of 100 samples of Setbag net fishing boats were selected, of which 40 were from Cox’s Bazar, 40 were from Chittagong and 20 were from Bagerhat. Stochastic frontier (with technical inefficiency effect) model was specified and estimated. Results have shown that the estimated mean technical efficiency of Setbag net fishing boats is 84 percent. The efficiency of Setbag net fishing boat was positively associated with total cost, while the number of nets were negatively related to fishing day and crew size. Head maji’s age had significant effect on inefficiency at 5% level. Although, the effect on boats’ efficiency was positive, (though insignificant) for head maji’s experience, head maji’s education, engine horse power and boat age. The use of modern fishing boat and improved fishing technology should be promoted, through proper training and motivation program for fisher. At the same time old and unfit fishing boat and gears should be gradually removed and replaced by new and modern fishing boat.The Agriculturists 2017; 15(2) 59-65

  • Profitability and Comparative Advantage of Onion (Allium cepa) Production
           in Bangladesh: An Economic Study in Some Selected Areas

    • Authors: Arifa Anjum, Basanta Kumar Barmon
      Pages: 66 - 78
      Abstract: The present study attempted to estimate the profitability, domestic resource cost (DRC) and problems and prospects of onion production in the study areas. Both primary and secondary data were used in this study. Sample survey was carried out in two selected areas under Kushtia and Jhenaidah districts. A total of 110 onion producers were selected randomly of which 70 producers were from Kushtia and the remaining 40 producers were from Jhenaidah. The study showed that, on an average, total costs of onion production per hectare were about Tk. 150,097 and 116,831 in Kushtia and Jhenaidah district, respectively. The benefit cost ratios (BCR) of onion production were 2.02 and 1.83 in Kushtia and Jhenaidah district, respectively. The results of profitability and BCR show that onion is a profitable crop in Bangladesh. The domestic resource costs (DRC) were 0.47 in Kushtia and 0.52 in Jhenaidah, which indicate that Bangladesh has comparative advantage in onion production. The coefficients of the production function show that farm area, irrigation, pesticides, seeds, chemical fertilizers (TSP) and labor were statistically significant affecting factors of onion production and it shows constant returns to scale. The onion producers faced some production, technological and marketing related problems in the study areas. The government should therefore, take necessary policies for further development of onion production in Bangladesh.The Agriculturists 2017; 15(2) 66-78

  • Marine Fish Marketing and Prices Changes in Different Levels of Market in
           Bangladesh: An Empirical Study Using Primary Data

    • Authors: Md Golam Rabbani, M Serajul Islam, Rozina Yeasmin Lucky
      Pages: 79 - 87
      Abstract: Contribution of fisheries in the national economy of Bangladesh is substantial, particularly with reference to food consumption, nutrition, employment and export. The present study was designed to determine the changes of prices of marine fish at different levels of market and to determine various problems relating to marine fish marketing system in Bangladesh. This study used purposive sampling and data were collected from 168 stakeholders using interview schedule considering 10 major species of marine fish during 2014. Primary, secondary and consumer market were considered in the study. The study revealed that both marketing margins as well as marketing profit are relatively higher in consumer market followed by primary and secondary markets, where baparis and aratders are involved. Marketing costs for per kg of marine fish were estimated to be Tk 8.55, 1.10 and 4.50 for beparis, aratdars and retailers, respectively. Average marketing cost was lower in primary market (Tk 8.86/kg) compared to secondary market (Tk 9.99/kg) and consumer market (Tk 12.29/kg). The marketing system of marine fish in Bangladesh is yet to be developed and since this is facing a lot of problems including post-harvest losses, poor physical facilities, etc. Government and department of fisheries should take necessary action for development of marketing system of marine fishes.The Agriculturists 2017; 15(2) 79-87

  • The influence of Waterlogging Period on Yield and Yield Components of
           Mungbean (Vigna radiata L. Wilczek)

    • Authors: M R Amin, M A Karim, Q A Khaliq, M R Islam, S Aktar
      Pages: 88 - 100
      Abstract: Yield performance of 10 selected mungbean (Vigna radiata L. Wilczek) genotypes, viz. GK-7, GK-48, GK-65, VC-6173A, CO-3, IPSA-12, IPSA-13, IPSA-15, BARI Mug-5 and BUmug 2 was evaluated under waterlogged condition in the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during April to July 2011. Waterlogging depth was 3-5 cm, created by irrigation from tap water and imposed at 22 days after emergence of seedlings which was maintained for 2, 4 and 6 days in the three different treatments. Yield and yield contributing characters of the mungbean genotypes were significantly affected by waterlogging. The longer the waterlogging period, the more was the reduction in seed yield and yield contributing characters. Among the 10 genotypes, IPSA-13 performed the best in respect of grain yield production under waterlogging condition, which was followed by VC-6173A and BUmung 2.The Agriculturists 2017; 15(2) 88-100

  • Variability and Traits Association Analyses in Maize (Zea mays L.)

    • Authors: Masuma Rahman, Ahasanul Hoque, Md Amir Hossain, Md Abdullah Al Bari
      Pages: 101 - 114
      Abstract: An experiment was conducted at the experimental farm of the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh with fifteen maize (Zea mays L.) genotypes to assess the genetic variability, characters association and divergence among the genotypes for yield and yield attributing traits. The experiment was conducted during November 2015 to May 2016, following Randomized Complete Block Design (RCBD) with three replicates in two adjacent environments to discern the performance of the genotypes in interacting environments. No significant variation was observed for environments, which was perhaps due to their close proximity. The genotypes differed significantly for most of the studied traits. The phenotypic co-efficient of variation (PCV) was higher than genotypic co-efficient of variation (GCV) for all the evaluated traits. High heritability along with high genetic advance was observed for 1000 seed weight, seed numbers ear-1 and yield plant-1. Yield plant-1 was significantly associated with plant height, ear length, ear girth, husk girth, kernel length, 1000 seed weight, kernel numbers row-1, seed numbers ear-1 in positive direction and negatively associated with days to anthesis and moisture loss (%). Path co-efficient analysis revealed that the maximum positive direct contribution towards yield was through 1000 seed weight, seed number ear-1 and kernel length whereas plant height, ear girth, ear length, kernel numbers row-1 showed negative direct contribution towards yield due to negative indirect effects of several parameters. Cluster analysis exhibited five distinct groups. Considering mean values Cluster II provided the best result in terms of yield and earliness, followed by Cluster IV and V. The results of principal component analysis (PCA) revealed that first five components accounted for 82.7% of total variation. The findings indicate the presence of ample genetic diversity among maize genotypes which can be exploited in future breeding program for better utilization of maize germplasm.The Agriculturists 2017; 15(2) 101-114

           as Influenced by Plant Growth Regulators

    • Authors: M A F Mollah, M H K Rubel, I M Hasan, A Sultana, M Z Tareq
      Pages: 115 - 121
      Abstract: An experiment was conducted at Jute Research Regional Station (JRRS) of Bangladesh Jute Research Institute (BJRI), Kishoreganj during August 2009 to January 2010 to determine the effect of different plant growth regulators on seed yield and quality of olitorius jute using late jute seed production technique. The experiment was laid out in a randomized complete block design (RCBD) with four replications. Seven growth regulators with different brand names such as Bionik, Litosen, Okozim, Mirakulan, Planovit, Flora and Yield were used in the experiment. All the yield contributing characters increased due to the application of growth regulators over the control. The highest seed yield (2.91g/plant) was obtained with Bionik which was followed by Mirakulan> Okozim> Litosen> Planovit> Yield> Flora> control. The highest of 33.49% seed yield was found in Bionik over control.  In terms of quality of seeds, the plant growth regulator `Bionik’ performed the best.The Agriculturists 2017; 15(2) 115-121
