  • Evaluation of pumpkin (Cucurbita moschata Duch. Ex Poir.) for yield and
           other characters

    • Authors: B Ahmed, MAT Masud, M Zakaria, MM Hossain, MAK Mian
      Pages: 1 - 11
      Abstract: Nineteen inbreds of pumpkin (Cucurbita moschata Duch. Ex Poir.) were evaluated at the experimental farm of Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur during the rabi season of 2011-12 to select the promising inbreds for higher fruit yield along with other important characters. Thirteen quantitative and three qualitative characters along with fruit fly infestation and virus incidence were studied. The inbreds differed significantly in most of the quantitative characters. All the qualitative characters (fruit shape, fruit skin colour and flesh colour) showed distinct variation among the inbreds. All the inbreds except PK05, PK16, PK17 and PK18 were attacked with Water Melon Virus 2 (WMV2). Fruits of all the lines were more or less infested by fruit fly. The study revealed that the inbreds differing significantly in most of the parameters offer a good scope of selection of better inbreds for desired traits. The flesh thickness, average fruit weight, fruits per plant ranged from 2.61 to 5.39 cm, 1.41 to 5.78 kg and 2.96 to 7.58 respectively. On the basis of yield and other yield attributes nine inbreds viz., PK01, PK02, PK03, PK06, PK07, PK08, PK09, PK10 and PK16 were found promising. These inbreds will be helpful in breeding program to evolve high yielding varieties of pumpkin with better quality.Bangladesh J. Agril. Res. 42(1): 1-11, March 2017

  • Effect of leaf trichomes and meteorological parameters on population
           dynamics of aphid and jassid in cotton

    • Authors: MR Amin, R Afrin, MZ Alam, MM Hossain, YJ Kwon
      Pages: 13 - 25
      Abstract: This study was conducted with CB1, CB3, CB5, CB8 and C12 cotton varieties to determine the role of leaf trichomes and meteorological factors on the abundances of aphid and jassid. The mean population of the pests on the tested varieties differed significantly and showed negative correlation with trichomes. The pests were most abundant on CB12, and each variety revealed significantly higher population of jassid than that of aphid. Both the pests built up their population in the juvenile stage of the plants (73 days after sowing) and continued until harvesting. Aphid population was the highest on CB12 in the first week of November, whereas maximum abundance of jassid was on CB12 in the third week of December. Weather parameters were found insignificant on aphid abundance, but jassid population on the varieties was correlated with maximum and minimum temperatures, relative humidity and rainfall. Multiple regression equation based on weather parameters exerted 8.8 - 43.2% and 54.4 - 77.7% role on population build up of aphid and jassid, respectively. Maximum temperature had the most important effect which contributed 61.2% population fluctuation of jassid on CB12.Bangladesh J. Agril. Res. 42(1): 13-25, March 2017

  • Development of cost effective small No-till seeder for two wheel tractor
           in Bangladesh

    • Authors: Md Israil Hossain, MK Gathala, TP Tiwari, M Jahedul Islam
      Pages: 27 - 34
      Abstract: Two wheel tractor (Power tiller) is the common means of soil tillage and other farm operations in Bangladesh due to easy access in fragmented land size with affordable price. A low cost and small robust 2WT driven (12 hp) No-till seeder has been developed with press wheel attachment and inclined plate seed meter assembly in Farm Machinery & Postharvest Process Engineering Division, BARI, Bangladesh for seeding different kinds of seeds. This is a pull type implement hitched at drawbar point of 2WT replacing the regular rotary part. The developed No-till seeder was used in the farmer’s field of Rajshahi areas for wheat, maize, pulses, and rice establishment during the year 2011-2014. The planter can pull 4 tynes in soft and medium hard soil but 3 tynes for hard soil. The planter was capable to apply seed and fertilizer in the furrows. The width and depth of the furrow opening were 30 mm and 60 mm, respectively. The planting depth, row spacing and seed rate can be adjusted according to standard practices. The No-till seeder works effectively through high density crop residue (1.5-2.4 t/ha) without any problem as there are sufficient residue clearances between toolbar and ground surface. Depending on the level of weed situation, round up herbicide was applied 2 days before of planting. There were significant yield difference in wheat, pulses but rice yield was lower than conventional transplanting method. No-till planted crops show less lodging tendency compare to conventional planted crops. There were significant cost differences between no-till and conventional method. The planting costs of wheat and maize in Notill system were 60% and 86% less than conventional planting method. It also reduces the average turn around time 7-9 days between the two crops. The effective area coverage by the seeder was 0.13ha/hr. The No-till seeder is a low cost (US$ 350-400; without power unit), light in weight and local manufacturer can fabricate complete unit within a short period of time. The No-till seeder can be used in other countries where 2WT is the common farming equipment.Bangladesh J. Agril. Res. 42(1): 27-34, March 2017

  • Effect of insecticides on population reduction of sucking insects and lady
           bird beetle in eggplant field

    • Authors: NK Dutta, SN Alam, M Mahmudunnabi, MR Amin, YJ Kwon
      Pages: 35 - 42
      Abstract: This study evaluated the field efficacy of three newly introduced synthetic insecticides namely, Python 20SL (Nitenpyrum), Plenum 50WG (Pymetrozin), Polo 500SL (Diafentiuron) along with commonly used chemical Admire 200SL(Imidacloprid) against sucking insects of eggplant such as aphid, jassid, white fly and thrips. The effect of the insecticides on the population reduction of the novel predator lady bird beetle was also studied. Among the chemicals, Polo 500SC was found to be the most effective followed by Plenum 50WG against the sucking insects by reducing significant percentages of their population at 3 and 7 days after spray. Polo 500SC and Plenum 50WG were found to be the least deleterious against lady bird beetle since it caused lowest population reduction. Considering the higher percentages of population reduction of the pests and significantly lower affect on the predator, Polo 500SC and Plenum 50WG may be considered as a tool of IPM for management of sucking insects in the eggplant field.Bangladesh J.

  • Response of capsicum to boron and zinc application in terrace soils of
           Gazipur, Bangladesh

    • Authors: R Ahmed, MA Siddiky, MR Karim, MA Quddus, S Ahmed
      Pages: 43 - 52
      Abstract: A field experiment was conducted at vegetables research field of Horticulture Research Centre, Gazipur in terrace soils under Madhupur Tract (AEZ 28) during rabi seasons of 2009-10, 2010-11and 2011-12 to determine the optimum dose of boron and zinc for yield maximization of capsicum. There were sixteen treatment combinations comprising four levels each of B (0, 1, 2 and 3 kg ha-1) and Zn (0, 2, 3 and 4 kg ha-1) along with blanket dose of N150P65K120S20 kg ha-1 including cow dung 10 t ha-1 were used. The experiment was laid out in RCBD factorial with three replications. Results revealed that maximum mean number of fruits per plant (11.1), the highest fruit length (9.29 cm) and diameter (7.34 cm), maximum individual weight of fruits (122 g) were recorded from the combination treatment of B2.0Zn3.0 and the highest mean yield (31.8 t ha-1) was also recorded from the same treatment. The 84.8% yield increase over control (B0Zn0) due to combined application of B2.0Zn3.0 kg ha-1. The combined application of zinc and boron were observed superior to their single application. Therefore, the combination of B2.0Zn3.0 treatment may be considered as suitable dose for capsicum cultivation in terrace soils of Bangladesh.Bangladesh J. Agril. Res. 42(1): 43-52, March 2017

  • Dynamics of phytohormones and their relationship with chalkiness of early
           indica rice under different post-anthesis temperature regimes

    • Authors: Mohammed Humayun Kabir, Qing Liu, Yi Su, Zhigang Huang, Langtao Xiao
      Pages: 53 - 65
      Abstract: A pot experiment on an early indica rice cv. ‘Shenyou9576’ was conducted in the net house of Hunan Agricultural University, Changsha, Hunan, PR China during the early growing season of 2013 to investigate the influence of varying temperatures on chalkiness rate, head rice rate, and phytohormones, namely indole-3-acetic acid (IAA), gibberellins (GA1 and GA4), zeatin (Z), zeatin riboside (ZR) and abscisic acid (ABA) both in flag leaves and grain endosperm during grain filling period. The treatments comprised three temperature regimes which are designated as the high (35/28oC- day/night), low (25/20oC- day/night) and natural condition as the control (35/25oC- day/night). The results showed that the maximum chalkiness rate was 61.11% under high temperature and the minimum (22.59%) under low temperature. The lowest head rice rate was 42.76% under high temperature followed by 49.91% in the control, while the highest (62.33%) under low temperature. The contents of GA1, GA4, Z and ZR were decreased gradually from 7 to 35 days after anthesis (DAA) irrespective of treatments. IAA content began to decrease from 14 DAA and continued up to 35 DAA and ABA was reduced from 28 to 35 DAA under low temperature in comparison to control and high temperature. ABA content was increased from 7 to 21 DAA and then declined at high temperature. The results showed that contents of GA1, GA4, Z, ZR were high at low temperature compared to high temperature and control. IAA content was also high during grain development period at low temperature except 7 DAA. Higher phytohormone contents were observed in endosperm than in flag leaves. Phytohormone content ratio (endosperm: flag leaves) was found highest in IAA and the lowest in GA1. A significant positive correlation was found between ABA and chalkiness rate during early to mid grain filling period, while significant negative correlations were noticed between chalkiness rate and other phytohormones during grain filling period. Correlation results revealed that increased level of ABA during early to mid grain filing period caused by high temperature was more responsible for development of chalkiness.Bangladesh J. Agril.

  • Crop coefficient of a popular potato variety in Bangladesh

    • Authors: AR Akanda, MS Rahman, MS Islam, AJ Mila
      Pages: 67 - 76
      Abstract: Crop evapotranspiration (ETc) and crop coefficient (Kc) values of potato (variety: BARI Alu -7, Diamant) at different growth stages were determined through lysimeter method at Irrigation and Water Management Division of Bangladesh Agricultural Research Institute (BARI), Gazipur during 2008 - 2009. The study was conducted by applying irrigation at 25 and 40 days after planting (DAP) allowing drainage (AD) (T1), at 25, 40, and 55 DAP AD (T2), at 25, 40, and 60 DAP AD (T3), and at 25, 40, 55, and 60 DAP AD (T4) within and adjacent of four lysimeter tanks. Irrigation at 25, 40, and 55 DAP produced the highest tuber yield and was considered to be suitable for estimating seasonal ETc, and Kc values. The seasonal highest ETc was found to be 162 mm. The Kc values of 0.25, 0.62, 0.70 and 0.18 were determined at initial, development, midseason and late season stages of potato. These values differed slightly from the FAO recommended values. As the lysimeter provides control environment, the Kc values determined by this method are most dependable and recommended for estimating ETc of potato in semi-arid climatic conditions of Bangladesh.Bangladesh J.

    • Authors: MA Razzaque, MM Haque, MA Karim
      Pages: 77 - 85
      Abstract: A pot experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during kharif II season of 2011 to investigate the growth, dry matter production and yield of mungbean genotypes under nutrient stress soil. Ten mungbean genotypes viz., IPSA-12, GK-27, IPSA-3, IPSA-5, ACC12890053, GK-63, ACC12890055, BARI Mung-6, BUmug- 4 and Bina moog- 5 and six nitrogen fertilizer levels viz., 0, 20, 40, 60, 80 and 100 kg N ha-1 were included as experimental treatments. Results revealed that increasing nitrogen level in nutrient stress soil increased growth and dry matter production up to 60 kg N ha-1 irrespective of genotype and thereafter decreased. Among the mungbean genotype IPSA 12 showed maximum leaf area, dry matter production and seed yield (14.22 g plant-1) in nutrient stress soil. The lowest seed yield (7.33 g plant -1) was recorded in ACC12890053 under control condition.Bangladesh J. Agril. Res. 42(1): 77-85, March 2017

    • Authors: Tamer Üstüner
      Pages: 87 - 102
      Abstract: A study was carried out in Kahramanmaras region of Turkey during 2012-13 having ten subregions namely, Afsin, Andırın, Caglayancerit, Ekinozu, Elbistan, Göksun, Center, Nurhak, Pazarcık and Türkoglu to determine the range, density and frequency of weeds in apple orchards. In the orchards 133 weed species from 31 families were determined. The average density of weeds was 112.49 plants m-2. The maximum density of weed species was found in Göksun (127.30 plants m-2) followed by Elbistan (126.13 plants m-2), Ekinozu (125.95 plants m- 2), Afsin (120.39 plants m-2), Center (117.94 plants m-2) and Caglayancerit (114.90 plants m-2), and the minimurn density was determined in Pazarcık (69.51 plants m-2). From the identified 133 weed species one species belonged to Pterydophyta, 2l species to Monocotyledoneae and 111 species to Dicotyledoneae. The average densities of the weed species over l0 subregions for Agropyron repens (L.) P. Beauv., Chenopodium album L., Bromus arvensis L. and Amaranthus retroflexus L. were found to be 13.76, 12.17, 12.10 and 10.76 plants m-2, respectively. With regard to frequency of occurrence, C. album L. was detected more than 56% in six subregions excluding Andırın, Pazarcık, Türkoglu and Center; A. retroflexus L. more than 54% in 7 subregions excluding Center, Pazarcık and Türkoglu and A. repens (L.) P. Beauv. more than 50% in 10 subregions. Frequency of occurance of Cynodon dactylon (L.) Pers. was observed 50.1, 50.9, 76.9% in Afsin, Caglayancerit and Andırın, respectively and it was below 50% in other 7 subregions. In terms of coverage, Alopecurus myosuroides Huds., A. retroflexus, A. repens, B. arvensis, C. album, Convolvulus arvensis L., C. dactylon and Lactuca serriola L. were determined to be within the range of 20.2 to 48.2% in the study areas while the other species were below 20%.Bangladesh J.

  • Morphological characterization of geographical indication litchi crops and
           released varieties grown in Bangladesh

    • Authors: MA Hossain, MR Molla, I Ahmed
      Pages: 103 - 120
      Abstract: Four Geographical Indication litchi genotypes (GIs) viz., Kadmi Lichu, Mongalbari Lichu, Deshi/Ati/Rajshahi Local (BARI Lichu-1) and Bedana Lichu, and three released varieties viz., BARI Lichu-2, 3 and 4) were characterized morphologically during July 2012 to June 2013 with a view to identifying the degree of morphological and genetic variation of litchi within cultivars, and to establish a permanent database for documentation of litchi. Morphological characterization data were recorded from standing trees of the most concentrated areas of cultivation for GIs and the respective stations from where the variety was released viz., Kadmi from Sonargaon, Narayanganj; Mongalbari from Pakundia, Kishoreganj; Rajshahi Local from Mohanpur village of Shyampur union under Rajshahi district; Bedana from Masimpur, Dinajpur; BARI Lichu-2 and BARI Lichu-3 from RARS, Akbarpur and BARI Lichu-4 from BSPC, Debiganj. Historical background of geographical indication crops of litchi as described by aged people of their most concentrated areas of cultivation indicated that the cultivars were originated naturally in those areas. The cultivars were very location specific. They do not perform well in respect of yield and quality outside their areas of origin indicating their very narrow adaptability range. It was another indication regarding location of origin of the GI crops. On the other hand, the exotic cultivars grown in the country such as BARI Lichu-2, BARI Lichu-3 etc. possess country wide adaptability. Wide variations were observed among the GI crops and released varieties included in this study for plant, leaf, inflorescence, flower and fruit characters. Variation was also recorded in respect of incidence of biotic and abiotic stresses like insect pests, mites, diseases, sunburn, fruit cracking and fruit drop. Each GI/released variety possesses some unique characters, which distinguish it from all other genotypes.Bangladesh J. Agril. Res. 42(1): 103-120, March 2017

  • Nutrient balance under wheat-mungbean-T. Aman cropping pattern in
           calcareous soils of Bangladesh

    • Authors: MA Quddus, J Αbedin Mian, HM Naser, MA Hossain, AKM Salauddin
      Pages: 121 - 136
      Abstract: Field experiments on Wheat-Mungbean-T. aman cropping pattern were conducted at Regional Pulses Research Station (RPRS), Madaripur in calcareous soils under Low Ganges River Floodplain (ΑEZ-12) during 2009 to 2010 to prepare nutrient balance sheet for the cropping pattern and fertilizer recommendation for study area. The treatments were T1= Control; T2 = Farmer’s practice; T3 = AEZ based recommended fertilizer dose and T4 = Soil test based fertilizer dose. The experiment was laid out in RCBD with three replications. Results revealed that the average yields of wheat, mungbean and T. aman ranged from 1517 to 3124 kg ha-1, 1320 to 1863 kg ha-1 and 2974 to 4859 kg ha-1, respectively. Grain yield of all crops increased significantly higher in soil test based (STB) fertilizer treatment (T4) over the other treatments. Among the major nutrients, the magnitude of negative balance was greater with N and K followed by Mg and Ca. The negative balance of N (-56.0 to -183 kg ha-1), K (- 71.0 to -167 kg ha-1), Ca (-7.50 to -27.1 kg ha-1), and Mg (-16.7 to -35.7 kg ha-1) was observed in all the managements might be due to added lower amount of nutrients in soil and higher removal by the crops from the soil. Positive balance of P indicated that the added amount of P is larger than the removal; P fertilization was enough to make apparent balances positive. Across various treatments, there was some amount of positive apparent S balance except absolute control plots and farmer’s practice. On the other hand, Zn and B balance in the system was neutral to slightly positive. Results revealed that, N, K, Ca, and Mg balance after two years of cropping was negative regardless of soil type and management strategies adopted. There was an improvement in organic matter in all treatments where biomasses of mungbean were incorporated. Organic matter, N, P, S, Zn and B status in soil was improved due to soil test based fertilization over the initial status. Considering the gross margin and soil fertility the soil test based (STB) fertilizer management practice is economically profitable and sustainable.Bangladesh J. Agril.

  • Comparative profitability analysis of shifting land from field crops to
           mango cultivation in selected areas of Bangladesh

    • Authors: S Khandoker, MA Monayem Miah, MA Rashid, M Khatun, ND Kundu
      Pages: 137 - 158
      Abstract: Mango has emerged as an important area for diversification and as an alternative cropping pattern due to higher returns and productivity. The study was conducted in three mango growing districts, namely Chapai Nawabganj, Natore, and Rajshahi during 2014-2015 to estimate the financial benefit of shifting cereal lands to mango production, factors influencing shifting decision, and explore related problems of mango cultivation in the study areas. A total of 180 farmers taking 60 farmers from each district were selected through using multistage stratified random sampling for the study. About 49% lands were shifted to mango cultivation from cereal crops which was higher in Chapai Nawabganj (55%) followed by Natore (48%) district. The main reason of this shifting was reported to be higher profit compared to other crops. The average total cost of mango cultivation was Tk. 1, 33,889 per hectare. Higher cost was observed in the 16th-20th year of garden (Tk. 1, 52,010) followed by 11th -15th year (Tk. 1, 48,952). The average yield of mango was found to be the highest in 16th – 20th year (26.48 ton/ha) followed by 11-16th year (19.38 ton/ha). Per hectare net return from mango cultivation was Tk. 1, 75,244. Total cost of mango cultivation was 10% higher than Boro-Fallow-T.Aman cultivation. On the other hand, total cost was about 40% lower than Wheat- Jute- T.Aman, Wheat-Aus-T.Aman and Potato-Fallow-T.Aman. The net return from mango cultivation was 75% higher than other cropping patterns. The shifting of cereal lands to mango cultivation was found to be a profitable since the BCR (2.89), net present value (Tk. 33, 71,166) and internal rate of return (39%) were very high. Relative income, farm size and education turned out to be positively significant, whereas age was negatively significant for shifting decision from cereal crops to mango cultivation. Therefore, Farmers should be motivated to cultivate mango in the fallow lands or areas where other crops are not grown well.Bangladesh J. Agril. Res. 42(1): 137-158, March 2017

           brinjal

    • Authors: MI Faruk, ML Rahman
      Pages: 159 - 170
      Abstract: Efficacy of three different substrates viz., rice bran, wheat bran, grass pea bran and their combinations with mustard oilcake (MOC) were tested to formulate a suitable Trichoderma harzianum based bio-fungicide for controlling seedling disease of brinjal caused by Rhizoctonia solani in tray soil as well as in seedbed soil under net house condition of Bangladesh Agricultural Research Institute (BARI), Gazipur during 2010 to 2014. The results of three years experiments revealed that T. harzianum bio-fungicides formulated in five different combinations of substrates viz., (1) rice bran + wheat bran, (2) rice bran + mustard oilcake (MOC) (3) rice bran + grasspea bran, (4) rice bran + wheat bran + MOC and (5) rice bran + grasspea bran +MOC were equally effective to control the soil borne seedling disease of brinjal caused by Rhizoctonia solani in tray soil and seedbed condition. In addition, vegetative growth of brinjal seedlings viz., shoot length, shoot weight, root length and root weight were enhanced significantly by the T. harzianum bio-fungicides in R. solani inoculated seedbed condition.Bangladesh J.

  • Postharvest loss assessment of major fruits grown in hill regions of
           Bangladesh

    • Authors: MA Hossain, M Khatun, MA Matin, MF Dewan
      Pages: 171 - 184
      Abstract: The study was conducted for assessing postharvest loss of major fruits in different hill regions of Bangladesh. The study areas covered four hill districts, namely Rangamati, Khagrachari, Bandarban and Moulvibazar and six selected fruits, namely mango, jackfruit, litchi, banana, pineapple and orange. These fruits are grown intensively in hill regions compared to other parts of Bangladesh. Data were collected from 2050 fruit growers and 749 traders of eight (8) upazilas considering accessible and less accessible areas. At farmers and traders level, the total postharvest loss of banana, pineapple, orange, mango, litchi and jackfruit were 372, 274, 200, 243, 165 and 380 kg/mt which was accounted about 37%, 27%, 20%, 24%, 17% and 38% of total production respectively. The main postharvest losses at farm level were incurred due to severe attack of insect, bat, squirrel and monkey. For traders, major losses were incurred during transportation. On the basis of retail price, the annual economic loss was estimated as Tk. 2107.5 crore and the maximum loss was incurred for banana (Tk. 705.79 crore) followed by pineapple (Tk. 550.58 crore) and mango (Tk. 508.95 crore) and the lowest for orange (Tk. 1.12 crore). It is interesting to note that, transportation dummy, labour dummy and market demand dummy had negative and significant effect on the postharvest losses. If transportation facilities can be improved and market demand and labour availability can be increased, postharvest loss will be decreased to an acceptable level at the study areas.Bangladesh J.
