  • Bio-rational management of whitefly (Bemisia tabaci) for suppressing
           tomato yellow leaf curl virus

    • Authors: MM Alam, MN Islam, MZ Haque, R Humayun, KM Khalequzzaman
      Pages: 583 - 597
      Abstract: Whitefly (Bemisia tabaci) is the vector of tomato yellow leaf curl virus (TYLCV), is a serious pest of vegetables and other crops worldwide. The experiment was conducted at Bangladesh Agricultural Research institute (BARI) during two consecutive years of 2009 and 2010 to select a suitable bio-rational management practice against white fly, transmitting TYLCV. Treatments comprising tomato variety Ratan with diseased plant uprooting, spraying admire, applying admire on trap crop (marigold), spraying neem, sesame and mustard oil with trix and the untreated control were used in this experiment. The variety Opurba with similar materials as described above was used. Percent virus infected tomato plants ranged from 1.33 to 19.00 in two consecutive years, where the highest infection was recorded in control plot with variety Opurba and the lowest was recorded in variety Ratan treated with Admire. Consequently, the highest yield (47.70 and 52.36 t ha-1 in 1st and 2nd year, respectively) in the plots of variety Ratan treated with admire and the lowest yield was recorded in untreated control plots with variety Opurba (14.75 and 30.30 t ha-1) for the two consecutive years. A strong positive correlation was observed between whitefly population and % TYLCV infection for both the years and both varieties of tomato. While a negative correlation was observed between % TYLCV infection with number of fruits plants-1 and yield (t ha-1) for both the years and in both varieties of tomato. These results are consistent with the occurrences of TYLCV, which have been associated with the percent virus infection in relation to yield and yield contributing characters of tomato.Bangladesh J.

      Pages: 599 - 623
      Abstract: The study was conducted in Bogra and Satkhira districts to assess the socioeconomic status, profitability, problems and prospects of sunflower cultivation in Bangladesh. A total of 100 sunflower cultivating farmers, taking 50 farmers from each district, were randomly selected for this study. About 18% female farmers were also found to cultivate sunflower due to its beauty and easy cultivation method. Majority of the farmers had only one year experience of sunflower cultivation. Per hectare cost of producing sunflower was estimated as Tk. 62,199. Per hectare net return and BCR were Tk. 10,863 and 1.18, respectively which indicated that sunflower cultivation was profitable. Stochastic frontier function revealed that the use of labour, seed, organic fertilizers, cost of irrigation, and land type had positive and significant effect on the yield of sunflower. Average technical efficiency of the farmers was 86% which implies that there is a scope of increasing productivity of sunflower by 14% using current level of inputs by increasing the farmers’ efficiency. Lack of irrigation facility, scarcity of seed on time, absence of sunflower oil mill and sunflower market, low demand for sunflower, high cost of seed, etc. were the major problems of sunflower production and marketing. In spite of having some problems 18% female farmers became interested to cultivate and 46% farmers of Satkhira district mentioned that their demand for edible oil is becoming fulfil. So there is great potentiality of sunflower cultivation in Bangladesh. The availability of sunflower seed with low cost and establishment of sunflower oil mill is needed to sustain this crop in Bangladesh. Therefore, import dependency on soybean oil will be reduced.Bangladesh J. Agril. Res. 41(4): 599-623, December 2016

  • Infestation of four mustard varieties by Lipaphis erysimi (Kalt) in
           relation to different levels of irrigation

    • Authors: MA Mannan, N Tarannum
      Pages: 625 - 632
      Abstract: An experiment was conducted to find out the influence of three irrigation levels (no irrigation, one irrigation and two irrigation) on four mustard varieties (Tori- 7, BARI Sharisha-6, BARI Sharisha-9 and BARI Sharisha-8). The non-irrigated plots had highest aphid population (34.96/plant) and lowest (11.16 aphids/plant) in two irrigation. The variety BARI Sharisha-8 showed lowest (5.34 aphids/plant) aphid infestation and its yield was highest (2.05 ton/ha). Interaction effects indicated that the crop escaped from the aphid incidence in the variety BARI Sharisha-8 irrigated 2 times and produced highest yield (2.37 ton/ha). The differences in the aphid population at three irrigation levels affected the yield contributing characters and it was negatively correlated (correlation coefficient value ‘r’ ranged from -0.91 to 1.0).Bangladesh J.

    • Authors: AA Begum, MSU Bhuiya, SMA Hossain, Amina Khatun, SK Das
      Pages: 633 - 645
      Abstract: The experiment was conducted at the research field of Agronomy Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during 2011-12 to find out proper combination of fertilizer nutrients of potato hybrid maize intercropping system for higher productivity and economic return. Ten fertilizer dose viz., F1= Control (without fertilizer), F2=260P72K148S48Zn4B2 (100% recommended fertilizer, RF for hybrid maize HM), F3=N180P40K180S20Zn4B1.2 (100% RF for potato), F4=N440P112K328S68Zn6B2 (100% RF for HM + 100% RF for potato), F5=N352P90K262S54Zn6B2 (80% RF for HM + 80% RF for potato), F6=N395P102K283S63Zn6B2 (100% RF for HM + 75% RF for potato), F7=N350P92K238S58Zn6B2 (100% RF for HM + 50% RF for potato), F8= N375P94K291S56Zn6B2 (100% RF for potato + 75% RF for HM), F9=N310P76K254S44Zn6B2 (100% RF for potato + 50% RF for HM) and F10=N320P73K170S50Zn6B2 kg ha-1 (BARI RF for potato hybrid maize intercropping) were tested on potato hybrid maize intercropping system. BARI Alu-8 (Cardinal) variety of potato and BARI Hybrid maize-7 variety of hybrid maize were used in this study. Maximum photosynthetically active radiation interception, leaf area index and total dry matter production of intercropped potato and maize were observed at the highest fertilizer level N440P112K328S68Zn6B2 kg ha-1 (100% RF for HM + 100% RF for potato). The highest tuber yield of potato (30.20 t ha-1) and grain yield of maize (9.48 t ha-1) were observed from fertilizer dose of N375P94K291S56Zn6B2 (100% RF for potato + 75% RF for HM). The highest potato equivalent yield (40.47 t ha-1), gross return (Tk.526110 ha-1), gross margin (Tk. 381957 ha-1) and benefit cost ratio (3.65) were also observed from the same fertilizer rate. The results revealed that fertilizer dose of N375P94K291S56Zn6B2 kg ha-1 (100% RF for potato + 75% RF for HM) might be economically profitable for potato hybrid maize intercropping system.Bangladesh J.

  • Genetic divergence analysis in papaya (Carica papaya L.) Genotypes

    • Authors: N Ara, M Moniruzzaman, Ferdousi Begum, M Moniruzzaman, R Khatoon
      Pages: 647 - 656
      Abstract: The experiment on papaya (Carica papaya L.) consisting of fourteen genotypes from diversd gene pool was conducted at the Regional Agricultural Research Station, Ishurdi, Pabna during April 2013 to May 2014 to study the nature and magnitude of genetic divergence and eventually identification of suitable genotypes for use in breeding program. Multivariate analysis was subjected to assess the genetic diversity and Mahalanobis’ generalized distance (D2) was used to assess the divergence present among the genotypes. The fourteen genotypes were grouped into four clusters. The cluster IV had the maximum genotypes (5) followed by cluster I having 4 genotypes and cluster II having 3 genotypes. Cluster III had the minimum genotypes (2). The inter-cluster distances were greater than intra-cluster distances in all cases, suggesting wider genetic diversity among the genotypes of different groups. The highest intracluster distance was observed in cluster III and the lowest in cluster II. The maximum inter-cluster distance was estimated between clusters I and IV (11.3212), moderate distance between clusters II and IV (9.961) and clusters III and IV (7.568), and that of the lowest between clusters I and III. Cluster III recorded the highest mean values for fruit length, plant height at last harvest, number of fruits/plant, weight of fruits/plant and fruit yield, while cluster IV exhibited the maximum mean values for pulp thickness, plant height at 1st harvest and the second highest mean values for fruit length, fruit breadth and TSS. Therefore, more emphasis should be given on cluster III for selecting genotypes as parents for crossing with the genotypes of cluster IV which may produce new recombinants with desired traits.Bangladesh J.

      Pages: 657 - 665
      Abstract: A survey was conducted during July 2009 to October 2010 to know the occurrence of okra shoot and fruit borer species that infest okra in Bangladesh. Infested okra fruits were collected from eleven selected locations representing 11 Agro-ecological Zones of Bangladesh and reared in the laboratory. A total of 423 adult individuals consisting of 188 male and 235 female moths emerged from the infested fruits. The male and female ratio was 1.00∶1.25. The morphological characteristics of adult moths were recorded. Head and thorax of adults are ochreous white; forewings are pale white with a wedge shaped horizontal green patch in the middle and hind wings are silvery creamy white in color. The males are smaller than the females in size and the females are Vshaped at the end of the anal part but the males have thick hairs at the end of the anal part. Pupae are chocolate brown, bluntly rounded and enclosed in grey colored inverted boat shaped cocoon formed in the fruit or in the sand. Full grown caterpillars measured 1.64 cm in length and their color is brownish with white streaks dorsally and pale yellow ventrally, without finger tipped process. The recorded morphological characteristics ware compared with standard key and the insects were identified as Earias vittella belonging to the family Noctuidae.Bangladesh J. Agril.

    • Authors: MN Islam, MIU Sarkar, MH Ali, A Islam, PK Saha
      Pages: 667 - 673
      Abstract: A series of field experiments were conducted at farmers’ fields under Ganges Tidal Floodplain (AEZ-13) during 2012-2014 to identify suitable fertilizer management practices for maximizing rice yield. The treatments were: T1 = AEZ basis BRRI recommended fertilizer dose (BRRI dose), T2 = Rice Straw (RS)/Cowdung (CD) + IPNS (Integrated Plant Nutrition System) basis fertilizer management (RS/CD+IPNS) and T3 = Farmers’ Practice (FP). BRRI dhan27 (T. Aus), BRRI dhan49 and BRRI dhan54 (T. Aman) and BRRI dhan29 and BRRI dhan47 (Boro) were used as test varieties of rice. All fertilizers except urea were applied at final land preparation. In T. Aus and T. Aman seasons, urea was applied in two equal splits as FP. In Boro season, urea was added in three equal splits as FP. Urea Super Granule (USG) was applied at 12-15 DAT for T1 and T2 treatments. Treatment RS + IPNS gave 19-27% higher grain yield over FP and it saved full dose of K and S and partial dose of P fertilizer. Treatment CD + IPNS gave a 10-16% higher grain yield over FP and it saved full dose of P, K and S fertilizer in T. Aus and T. Aman seasons. On the other hand, BRRI recommended fertilizer dose gave 7-15% higher grain yield over FP.Bangladesh J. Agril. Res. 41(4): 667-673, December 2016

      Abstract: The study was undertaken to determine the purity of available marketed brands of nine selected pesticide groups viz., chloropyriphos, diazinon, carbofuran, pyrazosulfuranethyle, dimethoate, cypermethrin, carbendazim, mencozeb and quinalphos. These pesticides were collected from local markets of eight locationsviz., Rajshahi, Rangpur, Dinajpur, Bogra, Chittagong, Mymensing, Comilla, Norshingdi and Jessoredistricts of Bangladesh where extensive usage of pesticides was recorded. Among the 66tested pesticides, 66.66 % (44 in number) were found ˃90% pure in terms of active ingredient (AI). The purity range of about 12% of the total tested brands was 80%--90%. And the remaining 21.34% were less than 80 % pure, of which three pesticide brands contained no active ingredient (AI) at all.Bangladesh J. Agril. Res. 41(4): 685-694, December 2016

  • Opportunities of groundnut cultivation and marketing system in char lands
           of Bangladesh

    • Authors: MS Hoq, QMS Islam, S Khandoker, MA Matin
      Pages: 695 - 711
      Abstract: Bangladesh has vast char area but most of the char lands are not suitable for crop production. So the present study was undertaken to examine the suitability of crop production by assessing adoption, relative profitability, marketing system, production and marketing problems of rabi season groundnut in char lands of Faridpur, Jamalpur, and Kishoreganj districts during 2013-2014. The sample size of the study was 225 including 90 groundnut farmers and 135 traders. The study revealed that the highest (56%) percent of groundnut farmers cultivated Dhaka-1 variety and only 23% of all farmers cultivated BARI chinabadam-8.The per hectare production cost of groundnut was Tk 61,547, net return was Tk.42,033 and BCR was 1.68. The partial budgeting analysis showed that if the farmers cultivated groundnut instead of its competitive crops, they would receive Tk. 24,445 additional to sesame and Tk.21,990 additional to wheat cultivation. The average estimated marketing costs was highest (Tk.1388/quintal) for Stockist and lowest (Tk.55/quintal) for Arathdar. Net marketing margin was also highest (Tk.1212/quintal) for Stockist and lowest (Tk.59/quintal) for Arathdar. Marketing chain-v was the most efficient than other five chains because it has single involvement of intermediary. The major problems identified by farmers were lack of irrigation facilities (34%), low rate of seed germination (31%), and lack of cultivable land (29%). Major marketing problems were lack of cash capital (82%), and lack of storage facilities (55%) etc. Arrangement of institutional credit with low interest rate (80%), collateral free credit (45%), and arrangement of storage facilities (72%) were the trader’s opinion to minimize the marketing problems of groundnut. Therefore the study will be helpful to increase groundnut cultivation and improved the marketing system in char lands of Bangladesh.Bangladesh J. Agril. Res. 41(4): 695-711, December 2016

  • Effect of spacing and fertilizer management on the yield and yield
           attributes of mukhikachu (Colocasia esculenta Schott.)

    • Authors: S Akther, F Ahmed, MR Islam, MA Hossen, AHMM Rahman Talukder
      Pages: 713 - 723
      Abstract: Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

  • Efficacy of some new genearation insecticides and a botanical against
           mustard aphid and their toxicity to coccinellid predators and foraging

    • Authors: NK Dutta, SN Alam, M Mahmudunnabi, MF Khatun, YJ Kwon
      Pages: 725 - 734
      Abstract: Field studies were carried out to evaluate the efficacy of four new generation insecticides along with a botanical against mustard aphid (Lipaphis erysimi Kalt.) and their toxicity to coccinellid beetles and foraging honeybees during 2014-15 at Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh. Buprofezin 40 SC was found to be the most effective against aphid offering the lowest aphid population (1.56/ top10cm central twig) at 7 days after spraying (DAS) which was statistically identical to Diafenthiuron 500SC (1.85/ top10cm central twig). Among the treatments, Azadiractin 1EC appeared to be safest to coccinellid beetles and foraging honeybees because it recorded the highest number of beetle (7.50 /5 plants) and honeybee (9.64 /plot/5 min) population at 7 DAS, although honeybee population did not vary statistically with that of Buprofezin 40 SC and Lufenuron 5EC treated plots. Indoxacarb 145SC was found to be the most toxic against honeybees. However, the highest yield was obtained from Buprofezin 40 SC (1.57 t ha-1) treated plot although this was statistically identical to that Diafenthiuron 500SC (1.52 t ha-1) and Azadiractin 1EC (1.48 t ha-1) treated plots.Bangladesh J.

  • Soil fertility status of some of the intensive crop growing areas under
           major agroecological zones of Bangladesh

    • Authors: NC Shil, MA Saleque, MR Islam, M Jahiruddin
      Pages: 735 - 757
      Abstract: Laboratory studies on soil fertility evaluation was carried out across major agroecological zones (AEZs) of Bangladesh to know the nutrient status of soils and to relate those with soil properties like pH, organic matter, CEC, and clay content. Thirty five composite soil samples were collected from intensive crop growing sites, which covered 17 AEZs of Bangladesh. After proper processing, the samples were analyzed for texture, pH, organic carbon, CEC, exchangeable cations (K, Ca, Mg and Na), total N, available P and S following standard methods. The textural class of the soils collected from AEZ 12 and 13 appeared to be mostly clay. Clay loam soil was found in AEZ 4, 8, 9, 11, 25 and 28. Loamy soil was seen in AEZ 1 while AEZ 22, 23 and 29 were mostly sandy textured. The results revealed that 65.7% of the tested soil was acidic while 25.7% was alkaline in nature. All the tested soils showed lower pHKCl compared to pHH2O thus possessed negative charge. About 68.6% of the collected soils contained low (1.10-1.70%) level of organic matter, 25.7% soils retained it at medium level (1.71-2.40) and 5.7% soils at very low level (<1.0%). All the tested soils appeared to be deficient (< 0.12%) in nitrogen content. 68.6% soil samples had the low level of available P while only 8.6% retained it an optimum amount. About 80% of the tested soils contained low level of available S (7.9- 14.7 mg kg -1) although coastal regions soils hold higher amount of available S. High CEC (20-38 cmol kg-1) was found in clay rich soils of AEZ 10, 11, 12, and 13. Study revealed that 40% of the collected soils were very low, 31.4% were low, 8.6% each of medium and optimum, and 11.4% contained high level of exchangeable K. The calcareous soils (AEZ 10, 11, 12 and 13) contained very high level of Ca. Non calcareous soils also showed fairly good level of Ca content except AEZ 1, 3, 23 and 29. Sandy textured soils of greater Dinajpur, Rangpur, Moulvibazar showed lower level of exchangeable Mg. About 86% of the tested soils had the lower (< 2%) potassium saturation percentage (KSP), which needs K application for sustainable crop production. Estimate showed that 44% variability for CEC may be attributed by clay content and the relationship was significant (p = 0.05). Again, 50.4 and 65.6% variability in exchangeable K and Mg, respectively may be governed by clay content of the soils, while such relationship for Ca was non-significant. CEC may contribute 62.2, 92.3 and 83.9% variability for exchangeable K, Ca and Mg content in soils, respectively. The fertility status of most of the studied soils (except AEZ 10, 12, 13 and to some extent 11) appeared to be low to very low, which demand judicious management in order to achieve food security and to conserve the soil fertility.Bangladesh J.

    • Authors: SS Kakon, MSU Bhuiya, SMA Hossain, Q Naher, Md DH Bhuiyan
      Pages: 759 - 772
      Abstract: Field experiments were conducted during rabi (winter) seasons of 2010-11 and 2011-12 at the Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur to study the effects of nitrogen and phosphorus on growth, dry matter production and yield of French bean. A randomized complete block design was followed with 10 combinations of N (0,50, 100, 150 and 200) and P (0,22, 33, 44 and 55) kg ha-1 along with a blanket dose of control. All the treatments showed the maximum leaf area index (LAI) at 65 days after sowing (DAS). All the treatments showed the maximum total dry matter production, crop growth rate and net assimilation rate at harvest and at 55-65 DAS, respectively in both the years. LAI, dry matter production, CGR, NAR and seed yield significantly increased with the increase in nitrogen and phosphorus level upto 150 kg N and 44 P kg ha-1 , respectively. Similar trend was followed in maximum number of pods (9.45) and seed yield (1563.33 kg ha-1). The treatment comprises with 150 kg N and 44 P Kg ha-1 gave the highest seed yield which was 51.40 and 54.30 % higher than control plots.Bangladesh J. Agril. Res. 41(4): 759-772, December 2016
