  • Effect of Nutrient Management on the Growth and Yield of Cabbage
           (Brassica oleracea var. capitata L.)
           in Calcareous Soils of Bangladesh

    • Authors: M N A Naher, M N Alam, N Jahan
      Abstract: An investigation was carried out in the calcareous soil of Chapai Nawabganj belonging to the High Ganges River Floodplain during November 2008 to March 2009 to examine the effect of different macro and micronutrients (N, P, K, S, Zn, B and Mo at 150, 50, 100, 20, 3, 3 and 1 kg/ha, respectively) on the growth and yield of cabbage. Application of different nutrients exhibited significant influence on the growth and yield of cabbage. The highest plant spread (70.76 cm), height (37.89 cm), leaf length (37.83 cm), leaf breadth (27.13 cm), head thickness (12.85 cm), head diameter (23.02 cm), marketable head yield (76.53 t/ha) which is 191% increase over control), early head formation and maturity were recorded from the plot receiving N, P, K and B at the rate of 150, 50, 100 and 3 kg/ha, respectively. The treatment N, P, K and S showed the highest weight of loose leaves (640 g/plant) and decreased the weight of folded leaves or head weight, whereas, the treatment N, P, K and B increased the folded leaves or maximum head weight (1894.18 g/plant).

    • Authors: S A Zomo, S M Ismail, M Shah Jahan, K Kabir, M H Kabir
      Abstract: An experiment was conducted to evaluate the changes in the chemical properties of banana fruits and their shelf life as influenced by different postharvest treatments. There were two varieties viz. Amritasagar (VI) and Sabri (V2) and seven storage treatments viz.: control (open space, 30±2ºC) (T0); perforated polyethylene, 30±2ºC (T1); non-perforated polyethylene, 30±2ºC (T2); benzyl adenine (BA 30 ppm, 30±2ºC) (T3); gibberellic acid (GA3 150 ppm, 30±2ºC) (T4); benzyl adenine (BA 30 ppm, 15°C ) (T5) and gibberellic acid (GA3 150 ppm, 15°C) (T6). A factorial experiment was laid out in the Completely Randomized Design (CRD) with three replications. Data were recorded on titratable acid content, total sugar content, reducing sugar content, non-reducing sugar content, total soluble solids and pulp pH. Among the chemical parameters, total soluble solids (TSS) and pH of pulp increased while titratable acidity decreased during storage in all the treated and untreated banana fruits. Among the treatments gibberellic acid (GA3 150 ppm, 15°C) treatment exhibited the best storage performance. The treatment combinations of Sabri with gibberellic acid (GA3 150 ppm, 15°C) showed the longest shelf life (16.25 days), whereas the lowest shelf life was in Amritasagar with control (open space, 30±2ºC) treatment combination (6.78 days).

           (Lablab purpureus (L.) Sweet) Genotypes

    • Authors: H Barua, M H Rahman, M M Alam Patwary, M Zahirul Alam, S Nahar
      Abstract: Variations in growth and yield of three hyacinth bean genotypes collected from Sitakundu of Chittagong, were investigated at the Agricultural Research Station (ARS) of Bangladesh Agricultural Research Institute (BARI), Pahartali, Chittagong during November 2011 to March 2012, where BARI Seem-4 was used as standard control. The minimum number of days for pod formation (54 days) was recorded in BARI Seem-4, while the maximum was in DLP 002 (62 days). The highest number of pods (324) per plant was obtained from DLP 001 followed by DLP 003 (212.33) and the lowest (148.33) was obtained from BARI Seem-4. The maximum weight (12.61 g) of single pod was observed in DLP 003, which is close to that of DLP 002 (12.23 g). The minimum weight of single pod (7.08g) was however observed in DLP 001. Weight of 100-green seed (117.17 g) was maximum in DLP 002, while that of DLP 001 was the minimum (85.90 g). The maximum green seed (61.86 %) was found in DLP 003 and the minimum was in DLP 001 (47.89 %). DLP 003 produced the highest pod yield (26.77 t/ha) which was followed by DLP 001 (22.94 t/ha), while BARI Seem-4 produced the lowest (17.43 t/ha), which is close to that of DLP 002 (19.57 t/ha).

  • Productivity of Fenugreek Varieties (Trigonella
    L.) in the Coastal Saline Areas of Noakhali

    • Authors: M M U Chowdhury, S K Bhowal, I S M Farhad, A K Choudhury, A S M M R Khan
      Abstract: The experiment was conducted at the farmer`s field of Boyerchor, Hatia, Noakhali under On-Farm Research Division, Bangladesh Agricultural Research Institute (BARI), during the rabi seasons of 2011-2013 to study the effect of variety on the productivity of fenugreek in coastal saline soil. The experimental treatments included 3 varieties viz. V1= BARI Methi 1, V2 = BARI Methi 2, V3 = Local Methi. The experiment was laid out in a randomized complete block design with six dispersed replications. There was a strong varietal influence on crop growth and seed yield. Among the varieties, BARI Methi 2 showed the best results in terms of plant height, number of branches, number of pods and number of seeds pod-1 resulting in the highest seed yield of 1497 kg ha-1. It was also observed that plant mortality of fenugreek was highly affected at germination stage when the soil salinity was above 4 dSm-1. However, at the later stages of crop growth up to the maturity, the salt tolerance of the crop was higher varying from 4-12 dSm-1. It was indicated that critical range of salinity level for cultivation of fenugreek was 3.42-12.2 dSm-1 from germination till to maturity. Among the fenugreek varieties, BARI Methi 2 offered the highest net return of Tk. 50150 coupled with a benefit cost ratio of 3.03. Though total cost was the same, BARI Methi 2 showed higher BCR (3.03) over BARI Methi 1 and local Methi due to yield differences.

  • Improvement of Tea (Camellia sinensis L.) Soil
           Properties by Growing Different Green Crops

    • Authors: Ashim Kumar Saha, Apu Biswas, Abdul Qayyum Khan, Md. Mohashin Farazi, Md. Habibur Rahman
      Abstract: Long-term tea cultivation has led to degradation of the soil. Old tea soils require rehabilitation for restoring soil health. Soil rehabilitation by growing different green crops can break the chain of monoculture of tea. An experiment was conducted at The Bangladesh Tea Research Institute (BTRI) Farm during 2008-2011 to find out the efficiency of different green crops on the improvement of soil properties. Four green crops such as Guatemala, Citronella, Mimosa and Calopogonium were grown to develop the nutritional value of the degraded tea soil. Soil samples were collected and analyzed before and at the end of experiment. Soil pH was increased in all four green crops treated plots with the highest increase in Citronella treated plots (from 4.1 to 4.5). Highest content of organic carbon (1.19%) and total nitrogen (0.119%) were found in Mimosa and Calopogonium treated plots, respectively. Concentration of available phosphorus, calcium and magnesium in all green crops treated plots were above the critical values, while available potassium content was above the critical value in Guatemala, Citronella and Mimosa treated plots. Changes in soil pH and available potassium were significant, while changes in organic carbon content, total nitrogen and available calcium were insignificant. Changes in available phosphorus and magnesium were significant.

  • Impacts of Famers’ Participation in Upscaling Technologies on
           Mungbean (Vigna radiata L.) Production in the
           South-Western Region of Bangladesh

    • Authors: M A Islam, M R Islam, M E Haque, F Yeasmin, M A Hossain
      Abstract: The study evaluated the farmers’ participatory methods of upscaling technologies for increasing mungbean production in the south-western region of Bangladesh. It was a descriptive survey study and data were collected by interviewing 120 sample farmers in DFID-Mungbean Project areas in Bangladesh. The participatory methods trailed in the project were farmers seed exchange program, demonstrations trials, agricultural training and workshops on mungbean production. However, farmers to farmers seed exchange program was identified as the most effective method. During the project phase, the farmers selected and adopted their preferred mungbean varieties, developed and practiced appropriate land preparation techniques along with improved post-harvest operations. Farmers’ participation in technology generation and upscaling resulted in increasing area and production of the mungbean many fold during 2004 to 2008. The average yield of mungbean was 1370 kg/ha and almost all framers obtained yields more than that of the national average of 705 kg/ha. Agricultural training, farm size and extension contact accounted for 83% of the total variation in upscaling technology and 90% of the variation in yield of mungbean. The extent of upscaling technology in terms of increase in area and yield of mungbean were associated with various participatory methods practiced by the farmers in the study area.

  • Carbon and Nitrogen Dynamics and Carbon Sequestration in Soils under
           Different Residue Management

    • Authors: M Mizanur Rahman
      Abstract: A study was conducted at the research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during August 2011 to May 2012 in two consecutive rice seasons of T. aman and Boro using three types of organic residues viz. poultry manure, cowdung and rice straw as treatments to quantify their effects on soil carbon, nitrogen, carbon sequestration and CO2 emission. Poultry manure was found efficient to increase carbon and nitrogen contents in soils compared to rice straw and cowdung, which decreased with increased soil depths irrespective of residues. Rice straw released more CO2 compared to poultry manure and cowdung. However, a positive trend of carbon enrichment in soils was found with the application these residues. The carbon sequestration in soils under poultry manure was 1.46 t ha-1, while it was 1.26 and 1.19 t ha-1 in cowdung and rice straw, respectively. Application of poultry manure and cowdung in soils should be considered and recommended to increase carbon stock and fetch multiple benefits in agriculture.

           Regulators and Organic Manures

    • Authors: M S Chowdhury, Z Hasan, K Kabir, M Shah Jahan, M H Kabir
      Abstract: A study was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Bangladesh during April to September, 2012 to determine the suitability of selected plant growth regulators and the proper use and effectiveness of selected organic manures and also their suitable combinations for successful okra production. The experiment consisted of two factors: factor A: growth regulators as - G0: control (water), G1: GA3 (100 ppm) and G2: Miraculan (1000 ppm) and factor B: organic manures as - OM0: control (no manure), OM1: vermicompost (9 t/ha) and OM2: poultry manure (11.5 t/ha). The combined use of GA3 and poultry manure produced the tallest plants. Both the growth regulators and organic manures enhanced early flowering. In case of growth hormone, the highest yield (16.67 t/ha) was recorded from G1 followed by G2 (16.49 t/ha). The highest yield (18.03 t/ha) was found from OM2, closely followed by OM1 (17.59 t/h). Considering the treatment combinations, the highest yield was harvested from G1OM2 (19.62 t/ha), followed by G1OM1 (19.01 t/h), G2OM1 (18.42 t/h) and G2OM2 (18.30 t/h), respectively.

  • Transfer of Arsenic from Groundwater and Paddy Soil to Rice
           (Oryza sativa L.) Grain: A Micro Level Study in
           Chandina, Comilla

    • Authors: Md. Habibur Rahman, Md. Mohashin Farazi, Kohinoor Begum, Md. Serazul Islam
      Abstract: Rice (Oryza sativa L.) is one of the major food crops in many countries. As the cultivation of rice requires huge volume of water, long term use of Arsenic contaminated groundwater for irrigation may result in the increase of arsenic concentration in the agricultural soil and eventually accumulation in rice grains. A micro level study was conducted to investigate the transfer of arsenic from irrigation water and soil to rice plants in the arsenic affected 8 unions of Chandina upazilla, Comilla district. The level of arsenic in irrigation water (0.12±0.08 and 0.67±0.07 mg l-1) was much above the WHO permissible limit of 0.01 mg l-1 for drinking water and FAO permissible limit of 0.10 mg l-1 for irrigation water. The total soil arsenic concentrations ranged from 3.21±0.80 to 8.74±2.83 mg kg-1 dry weight of soil, which was below the maximum acceptable limit for agricultural soil of 20.0 mg kg-1 as recommended by the European Community. The accumulation of arsenic in the grain ranged from 0.12±0.04 to 0.58±0.06 mg kg-1 in Boro and 0.16±0.04 to 1.06±0.20 mg kg-1 in T. Aman. Except grain sample (T. Aman) of one union, the grains in both Boro and T. Aman of all unions did not exceed 1.0 mg kg-1 dry weight of arsenic (the permissible limit of arsenic in rice according to WHO recommendation). Thus, till now rice has remained harmless for consumption in the study area. The results clearly showed that the arsenic content in the grains of Boro rice is correlated to the intensity of arsenic contamination of irrigation water and soil.

  • Contribution of Food for Work Program to Food Security of Selected Workers
           in Kapasia Upazila under Gazipur of Bangladesh

    • Authors: Shifat Sultana, Md. Safiul Islam Afrad, Foyez Ahmed Prodhan
      Abstract: The main focus of the study was to determine the food security status of the women involved in food for work program in terms of access to food (meals/day/person) and intake of energy (kilo calorie) and to explore the relationship between some selected characteristics of the beneficiaries with the changes in food security. The study was conducted in Kapasia upazila of Gazipur district during July 2013 to September 2013. Data were collected through pre-tested interview schedule. One hundred and ten women were selected following simple random sampling method. All of the family members of the respondents used to take three-meals/day when Food for Work Program (FFW) program was ongoing. More than four-fifth (84.55%) of the household members received optimum to above optimum kcal/day when FFW was running, but only three-fifth (60.90%) of the respondents’ family members took optimum to above optimum kcal/day when FFW program did not run. “Optimum level” and “above optimum level” calorie in taking family members increased by 12.73 percent and 10.91 percent, respectively when FFW program was running. The difference between per capita calorie intake by the respondents and their family members when FFW program was and was not running was found significant. Correlation analyses showed that annual income and credit facility had positive and significant relationship with contribution of FFW program on changes in food security status of the beneficiaries.

  • Effect of Unpuddled Transplanting on the Growth and Yield of Dry Season
           Rice (Oryza sativa L.) in High Barind Tract

    • Authors: A K M S Islam, M M Hossain, M A Saleque
      Abstract: Conservation tillage technology not only protects natural resources but also provides some economic leverage. The present investigation evaluated two puddle tillages (i) conventional tillage (CT) and (ii) single pass wet tillage (SPWT) and two unpuddled tillages(iii) strip tillage(ST) and (iv) bed planting (BP) to establish rice in the High Barind Tract, Godagari, Rajshahi during aus 2010 and boro 2011 season. The CT option incurred higher cost compared to other tillage treatments due to more fuel and labour used in land preparation. Minimum tillage (SPWT, ST and BP) saved about 30-54% fuel consumption and 40-49% labour requirement compared to CT in land preparation. Labour did not face much difficulty to transplant seedling in unpuddled fields. However, unpuddled establishment required more labor for weeding compared to puddle one. Bed planting in aus gave significantly lower grain yield than other establishment methods. However, in boro season, all the tested tillage methods produced similar yield. In both seasons, CT showed the highest input costs due to more number of tillage passes and fuel requirement in land preparation. As a consequence, SPWT, ST and BP appeared to be more profitable than CT both in aus and boro rice.

    L.) Production in Char Lands of Bangladesh

    • Authors: M M U Chowdhury, I S M Farhad, S K Bhowal, S K Bhowmik, A K Choudhury
      Abstract: An experiment was conducted at Char Martin under Multi Location Testing site in Laxmipur district during Rabi season of 2011-12 & 2012-13 with different fertilizer doses to find out the economic fertilizer dose for soybean variety BARI Soybean 6 under farmers field condition. Four fertilizer combinations viz; T1 : 17-27-55-2.7-2.0-0 kg ha-1 of N-P-K-S-Zn-B (Soil Test Based fertilizer), T2 : 25- 25-50-10-0-0 kg ha-1 of N-P-K-S-Zn-B (Fertilizer Recommendation Guide, 2005 based fertilizer), T3 : 28-13-0-0-0-0 kg ha-1 of N-P-K-S-Zn-B (Farmers practice) and T4: Native fertility (control) were selected. All the yield and yield contributing characters of BARI Soybean 6 varied significantly with the different fertilizer treatments. The highest seed yield (2.99 t ha-1) was recorded from plants treated with T1 which was statistically similar to T2. The lowest seed yield (1.74 t ha-1) was obtained from T4. The highest gross return (Tk.104650 ha-1), net return (Tk. 56375 ha-1) and benefit cost ratio (2.16) were obtained from T1 and the lowest gross return (Tk. 60900 ha-1), net return (Tk.19900 ha-1) and BCR (1.48) was obtained from T4 .

  • An Ex-Post Analysis of Ginger (Zingiber officinalis)
           Research and Extension Investment in Bangladesh

    • Authors: Md. Kamrul Hasan, M. Serajul Islam
      Abstract: The study estimated the benefit and rate of returns to investment on ginger research and extension in Bangladesh. The Economic Surplus Model with ex-post analysis was used to determine the returns to investment and their distribution between production and consumption. Several discounting techniques were also used to assess the efficiency of ginger research. The adoption rate was found increasing over the period. The yield of modern varieties of ginger developed by Bangladesh Agricultural Research Institute (BARI) was 78 per cent higher than that of the local varieties. Society got net benefit of Tk. 432.31 million by investing in ginger research and extension. The net present value (NPV) and present value of research cost (PVRC) were estimated to be Tk. 135.01 and 81.15 million, respectively. The internal rate of return (IRR) and benefit cost ratio (BCR) were estimated to be 32 per cent and 3.75, respectively indicating that investment on ginger research and development was profitable. Ginger seed production programme should be taken largely to increase production by increasing improved variety adoption area.

  • Impact of Lined Canal on Shallow Tubewell Irrigation and Their
           Acceptability by the Farmers

    • Authors: Abu Sayed, A F M Saleh, Md. Altaf Hossain, Zobayer Ali Basunia, Md. Afzal Hosain
      Abstract: The comparative conveyance losses between lined and unlined canals, impact of water saving on command area development and irrigation cost, and farmers’ acceptability of lined canal in shallow tubewell (STW) irrigation schemes were studied during 2010-11 Boro season at three upazilas: Manikgonj Sadar of Manikgonj district, Dhamrai of Dhaka district and Mithapukur of Rangpur district. The conveyance loss was measured using inflow-outflow method and focus group discussion (FGD) was carried out with the pump owners and farmers to assess the impact of water saving on command area development and the acceptability of lined canal technology. Average conveyance losses were found to be 41, 48 and 45% in the existing earthen canals; 18, 21 and 24% in improved earthen canals; and 12, 11 and 13% in pre-cast canals at Mithapukur (M1), Manikgonj Sadar (M2) and Dhamrai (D) schemes, respectively. The water saving did not increase the command area in any of the schemes but reduced the irrigation time and saved fuel requirement for irrigation. On an average, 32, 23 and 30% fuel were saved by improved earthen canals where as 45, 46 and 48% were saved by pre-cast canals for M1, M2 and D schemes compared to earthen canal. The benefit-cost ratios of improved earthen canals were 1.36, 1.38 and 1.30 where as 3.36, 4.28 and 3.34 by pre-cast canals for M1, M2 and D schemes, respectively. The internal rate of return (IRR) from the investment on water distribution was over 50%. The lining technology was acceptable to pump owners, but did not impress the farmers who share the crop with the pump owners as price of irrigation or pay on the basis of irrigated area. In order to make the technology acceptable to the farmers, polices must be framed to share the benefits of lining by the pump owners with the farmers by reducing the price of irrigation water or through financial support of GO and NGOs for efficient use of STW irrigation system in Bangladesh.

  • Impacts of Rice-Prawn Farming System on Farm Productivity, Food Security
           and Poverty Alleviation in Bangladesh: A Case Study in Khulna District

    • Authors: Basanta Kumar Barmon
      Abstract: The present study was undertaken to assess the impacts of rice-prawn gher (RPG) system on farm productivity, food security and poverty reduction in Bangladesh. In this study, farm survey data, extracted from a comprehensive questionnaire from two study villages viz. Bilpabla (RPG farming) and Chanchra (year-round modern variety–YRMV) located in Khulna and Jessore district, respectively were analyzed deliberately. This study consists of a random selection of ninety farmers from Bilpabla Village and one-hundred farmers from Chanchra. The study indicates that RPG farming system has significant impacts on farm productivity. On an average, yield of modern variety (MV) was reasonably higher in RPG farming system than that of YRMV farming system. In addition, the households engaged in RPG farming system (Bilpabla Village) have simultaneously generated more household income and per capita income (more than twice), relative to YRMV farming system (Chanchra Village). Moreover, the households of Bilpabla are superior to those households residing in Chanchra in terms of physical, social and economic access (purchasing power) which permits them to acquire and consume well-balanced food as well as sufficient calorie intake. Therefore, the RPG farming system had significant impacts on food security and poverty reduction.

    • Authors: M S Islam, M N Islam, H khatun, S Faruque, M A Afroz, M A Alam
      Abstract: This study was conducted to compare the productivity and profitability of trained and non-trained small-scale broiler farmers in the Joypurhat district of Bangladesh. A total number of sixty farmers were trained on the “modern techniques for profitable and sustainable broiler farming”. The study showed that the mortality of broiler was 2.90±0.89 percent and 11.30±2.29 percent for trained and non-trained farmers, respectively (P<0.001). Feed conversion ratio (FCR) was 1.65±0.08 and 1.75±0.10 for trained and non-trained farmers, respectively (P<0.01). The net profit was 18.60±2.77 and 8.74±2.05 taka per broiler for trained and non-trained farmers, respectively (P<0.001). It can be concluded from the present study that the family training would be a very essential tool for gaining more productivity and profitability of small scale broiler farming in Bangladesh.

      Abstract: Introduction of appropriate machinery is one of the major factors for reducing time and labor requirements, production cost and also to help fit another crop in between successive two crops. In this study, performance of the Bangladesh Rice Research Institute (BRRI) developed self-propelled reaper and an imported Chinese reaper were evaluated for rice harvesting and were compared with manual harvesting. The experiment was conducted at BRRI Regional station in Rajshahi and Rangpur during Boro 2012-13. Average field capacity of the BRRI reaper was 0.250 ha/hr and that of Chinese reaper was 0.203 ha/hr. The average field capacity of manual harvesting was 0.004 ha/hr. Labour requirements for rice harvesting including bundle making were 248 man-hr/ha, 69 man-hr/ha and 68 man-hr/ha for manual, Chinese reaper and BRRI reaper, respectively. On an average, 72 and 03% labour was saved by the BRRI reaper over those of manual harvesting and Chinese reaper, respectively. Harvesting costs were saved by BRRI reaper and Chinese reaper about 68 and 61%, respectively over that of manual harvesting. Average fuel consumption of Chinese reaper and BRRI reaper were 0.727 and 0.826 l/hr, respectively. The walking speed of BRRI reaper (3.78 km/hr) was 62% higher than that of Chinese reaper (2.33 km/hr). The purchase price of imported reaper is almost double than that of BRRI reaper. The BRRI reaper was, therefore, considered as a better machine for harvesting rice in Bangladesh.

  • Comparative Production Performances of Different Types of Quail
           (Coturnix coturnix japonica)

    • Authors: M S Islam, S Faruque, H Khatun, M N Islam
      Abstract: A study was conducted with four types of quail named Japanese (J), White (W), Black (BL) and Brown (Br) quail in BLRI, Savar, Dhaka to understand their productive and reproductive performances. A total of 1953 day-old chicks of quails were produced in successive two hatches. The highest fertility and hatchability were observed in White (98.13%) and Japanese (73.20%) types compared to their counterparts. White quail was significantly better for egg weight and chick weight than other the three types. The 5th week body weights were 117.94 ± 10.70, 114.71 ± 11.13, 98.28±9.69 and 107.24±8.98 g, respectively for W, Br, J and Bl. Significantly higher body weight was found in W and Br followed by Bl and J quail at different ages. The total number of eggs upto 24th week of age was 81.23 ± 0.67, 83.05 ± 0.69, 90.52± 0.56, and 93.31 ± 1.05 respectively, for W, Br, J and Bl and these significantly (p<0.001) differed among all genotypes. It may be concluded from the present findings that the performances of W and Bl quail were superior for body weight and egg number, respectively to the others. These findings give us more impetus for continuing the quail breeding research for producing a suitable meat type quail or egg type quail in the country.
