- Management of Saline Soil Using Organic Manure and Gypsum Fertilizer for
Growing Sweet Gourd in Coastal Region of Bangladesh
Authors: Mohammad Asadul Haque
Pages: 1–7 - 1–7
Abstract: Salinity is a major threat for growing cucurbit vegetables in the coastal zone of Bangladesh. A consecutive two year experiment was conducted during Rabi season 2019 and 2020 at Taltali and Amtali upazila, respectively of Barguna district Bangladesh to find out whether organic manure amendment and gypsum fertilizer can reduce salinity related degradation of soil and increase sweet gourd yield in coastal region of Bangladesh There were six treatments having control (no amendment), gypsum fertilizer, cowdung, poultry manure and the combination of gypsum fertilizer with cowdung and poultry manure. The design of the experiment was randomized complete block design with four replications. Every plot received recommended rate of nitrogen, phosphorus and potash fertilizer. The text crop was sweet gourd. Organic amendment significantly increase fruit yield of sweet gourd in saline soil. The performance of poultry manure was better than cowdung. The poultry manure, and poultry manure plus gypsum fertilizer produced fruit yield of 29.1 and 38.1 t ha-1, which is 67 and 119% higher over control treatment, respectively. The gypsum application had positive effect on fruit yield when it is applied with poultry manure. Application of organic manure increase soil moisture content, and reduce soil pH and electrical conductivity. Organic amendment with poultry manure is therefore recommended for sustainable yield of sweet gourd in saline soil, and reduces salinity related land degradation in coastal region of Bangladesh.

Authors: Arifa Sultana Shipa, Md Ruhul Amin, Md Ahsanul Haque Swapon, Abdul Mannan Akanda
Pages: 8–13 - 8–13
Abstract: Seasonal abundance of the sucking insect pests particularly the aphid and jassid on the cotton Gossypium hirsutum varieties CB12, CB13, CB14, CB15 and HC1, which are being cultivated in different Cotton Research and Multiplication Farms of Bangladesh, were studied from July 2018 to January 2019 at Gazipur in Bangladesh. The study also investigated the impact of weather parameters on the incidence of the pests. Aphids showed their abundance from the second week of October to the third week of November and the population revealed fluctuation. Aphid population reached to the peak in the fourth week of October (31.2/leaf) on HC1 followed by CB14, CB12, CB15 and CB13 cotton varieties. The weather factors collectively predicted 79.5% to 84.6% contribution on the abundance of aphid, and the highest and lowest effects were found on the varieties HC1 and CB14, respectively. Jassids showed their abundance from the first week of November to the second week of January and reached to the peak (7.2 leaf-1) in the fourth week of November on CB15 followed by CB12, CB13, HC1 and CB14 cotton varieties. The combination effect of the weather factors ranged from 57.4% to 71.0% abundances of jassid and the highest and lowest results were found on HC1 and CB15 varieties, respectively.

Authors: Md. Injamum-Ul-Hoque, Md. Nesar Uddin, Marzana Akter, Md. Rasel, Md. Abdullah Al Bari
Pages: 14–2 - 14–2
Abstract: Salinity is one of the most important abiotic stresses that adversely affects plant growth and development around the world. In order to elucidate the growth and physiological responses of maize genotypes under the first phase of salt stress (12 dS m-1 for two weeks), we investigated some growth and physiological traits at vegetative stage (28 d old plant) of four maize genotypes, namely indigenous yellow pure line, indigenous yellow, hybrid, and indigenous white. Salt stress significantly reduced shoot height and stem diameter in almost all genotypes. Under salt stress, instantaneous water use efficiency was highly increased in indigenous yellow pure line (285.5%), in contrast it was decreased significantly in hybrid (16.99 %) genotype compared to their respective control. Photosynthesis rate (70−87%), transpiration rate (81−91%), and stomatal conductance (80−92%) were significantly reduced due to salinity in all the tested genotypes. In the younger shoot, total phenolics content increased significantly in the young shoots of hybrid (42.26 %) and indigenous yellow pure line (40.03 %) genotypes under the first phase of salt stress. In contrast, there was no significant influence of salinity on total phenolics content of older shoot fraction in any genotype tested. Apparently, the growth and physiological traits were hampered in the first phase of salt stress in all tested genotypes. However, deposition of soluble phenolics under salt stress was genotype and leaf-region specific. As the most traits studied were highly influenced by the salinity in the first phase of salt-stress among genotypes at vegetative stage, breeders can potentially use these traits further in breeding program for the development of maize genotypes tolerant to the salt-stress at the vegetative stage of growth.

- Composition of Three Zingiberaceae Essential Oils and Their Efficacy
Against the Survivability of Cocoa Pod Borer, Conopomorpha cramerella
(Snellen) Eggs
Authors: Saripah Bakar, Siti Noor Hajjar Md Latip, Alias Awang, ; Aijun Zhang
Pages: 22–2 - 22–2
Abstract: The use of botanical extracts derived from potential plants is promising due to their target-specific, biodegradable, and can be implemented in insect management programs. This study was conducted to observe the potential of three Zingiberaceae essential oils; Lesser galanga, Alpinia galanga, Turmeric, Curcuma longa; and ginger, Zingiber officinale against the Cocoa pod borer, Conopomorpha cramerella (Lepidoptera: Gracillariidae) - the most devastating pest of cocoa in the Southeast Asia region. Bioassay on the C. cramerella eggs were performed using four different concentrations of EOs at 100, 200, 400, and 800 ppm. It is found that the A. galanga performed as the best EOs that can disrupt egg hatchability (0.025b ± 0.158), where only 0.03 eggs hatched and significantly different (p<0.05) with control (2.367a ± 0.928), where 2.37 eggs were successfully hatched. The concentration of EOs at 800 ppm was able to influence the penetration rate of pre-larva on the cocoa pod. During large cage observation, the mean of C. cramerella eggs were the highest at control (0.900a ± 1.029) and significantly different (p<0.05) with C. longa (0.150b ± 0.483), A. galanga (0.050 b ± 0.221) and Z. officinale (0.025 b ± 0.158). Higher concentrations (400 and 800 ppm) able to hinder C. cramerella from depositing eggs after cocoa pods were treated with treatments. The effect of Zingiberaceae EOs towards the egg hatchability may provide a foundation for their potential in managing C. cramerella in the future.

Authors: Nor Aizam Adnan, Saripah Bakar , Adam Harith Mazlan
Pages: 30–3 - 30–3
Abstract: The Malaysian Cocoa Board (MCB) has conducted numerous research and development activities to ensure the cocoa industry's sustainability. One of the essential aspects is the management of pests and diseases of cocoa. A qualitative study to detect the relationship between presences of biological control agents, Cocoa Black Ant (CBA) against the major pest of cocoa (Cocoa pod borer, CPB) with other ants' intrusion was done with the aid of geospatial mapping and analysis approaches. Other species of ants (ant invades) will affect the availability of CBA in controlling CPB infestation. Thirty months of data collection comprised two different blocks; Blocks 10B and 18A were used as the study area. Analysis of the differences and similarities of other ant's intrusion for each block and Plots was performed to understand the behavior and distribution pattern. Four different methods were introduced; Plot A was augmented with one artificial ant nest for every two cocoa trees, Plot B had one nest on every single cocoa tree, Plot C had two nests on every single cocoa tree, and Plot D without an artificial nest. The study reveals that the highest or lowest CBA populations and distribution could induce a strong, reasonable relationship against other ant types. Plots with artificial ant nests (A, B, and C) showed low intrusion rates with a ratio of 1:1 for Plot B indicated the best result, whereas, Plot without artificial ant nest (Plot D) the highest rate of intrusion during the months and years of observation. The findings in this research provide a new indicator of the ants' species interaction using temporal geospatial-based mapping and analysis within a cocoa plantation ecosystem J Bangladesh Agril Univ 19(1): 30–36, 2021 https://doi.org/10.5455/JBAU.37944

Approaches Under Variable Irrigation Regimes
Authors: Jotirmoy Chakrobortty, Subas Chandra Pal, M. Rafiqul Islam, Md. Anamul Hoque
Pages: 37 - 43
Abstract: Water scarcity is the main problem in boro season in Bangladesh which limits growth and development of crop plants especially in rice. The field experiment was carried out at the Soil Science Field Laboratory of Bangladesh Agricultural University. The experiment was laid out in a split plot design with three replications. BRRI dhan29 was used as a test crop. Treatments were the combination of water saving techniques and different nutrients of organic and inorganic approaches. There were four types of water management viz. I1: minimum irrigation, I2: normal irrigation, I3: continuous flooding and I4: alternate wetting and drying (AWD). On the other hand five fertilizers management approaches viz. F1: 100% recommended fertilizer dose (RFD) chemical fertilizers (NPKSZn), F2: 75% RFD chemical fertilizers (NPKSZn) + 5 t ha-1 cowdung, F3: 75% RFD chemical fertilizers (NPKSZn) + 5 t ha-1 cowdung slurry, F4: 75% RFD chemical fertilizers (NPKSZn) + 3 t ha-1 poultry manure and F5: 75% RFD chemical fertilizers (NPKSZn) + 3 t ha-1 poultry manure slurry were tested. The water management practices were placed in the main plot and fertilizer management practices were given in the sub plots. Results revealed that minimum irrigation caused significant reductions in growth and yield of BRRI dhan29. On the other hand, AWD technique did not reduce the growth and yield of BRRI dhan29 in comparison to continuous flooding. It was also revealed that plant height, panicle length, number of effective tillers per hill and grains per panicle were significantly increased in I3F3 (continuous flooding with 75% RFD chemical fertilizers + 5 t ha-1 cowdung slurry) treatment compared to other treatments. The highest grain and straw yields were obtained from I3F3 treatment. Nutrient uptake by BRRI dhan29 responded significantly in I3F3 treatment which was statistically similar to I3F4, I4F5, I2F5, I4F4 and I4F3 treatments. Finally it can be concluded that application of continuous flooding or AWD with 75% RFD chemical fertilizers + 5 t ha-1 cowdung slurry showed better performance than other treatments for maintaining better rice production.

under Different Management Practices
Authors: Md. Asaduzzaman Khan, Selina Aktar Shampa, Md. Baktear Hossain
Pages: 44–5 - 44–5
Abstract: The availability of nutrients in soils is dependent on a number of factors including the sources of the nutrient, moisture level and soil properties. The objective of this study was to determine the effects of irrigation, fertilizer and manure on nutrient availability in rice root zone and root free areas. The experiment was laid out in split plot design with a distribution of irrigation (I1: continuous flooding and I2: saturated condition) to the main plots and fertilizers to the sub plots. The fertilizer treatments were T0: Control, T1 =100% RDCF, T2 =50% RDCF + 5 t ha-1 cowdung, T3:70% RDCF + 3 t ha-1 cowdung, T4: 50% RDCF + 5 t ha-1 compost, T5: 70% RDCF + 3 t ha-1 compost, T6: 50% RDCF + 3.5 t ha-1 poultry manure, T7: 70% RDCF + 2.1 t ha-1 poultry manure. A PVC core was installed up to 40 cm depth in the middle of each plot and rice was not grown into the core but treatments were applied similar to the rice growing area and pore-water samples were collected from rice root zone and root free areas and analyzed. There was a positive correlation between rice yield and pore-water K or P of flowering stage. The higher pore-water nutrients and grain yields were obtained from organic plus inorganic fertilizer treatments. The 3 to 4 fold higher levels of pore-water K concentrations, 1.4 to 3 fold higher soil exchangeable K and 1.5 to 2 times soil available P were found in the soils of root free area than root zone area. The higher levels of soil organic matter, N, P and K were obtained in inorganic plus organic fertilizer treatments of root zone and root free areas and available P, K concentrations were highly increased in the soils of root free areas.

Abstract: Farmers of Bangladesh are cultivating an unidentified so-called purple rice (PR) having purple-colored leaf. Less information is available on PR in any areas of research in Bangladesh and the information about salt-stress tolerance potentiality of PR is absent. Here, we investigated salt stress-induced changes in PR to unravel its stress tolerance potentiality. The results of PR were compared with those of green rice (BRRI dhan28). The effects of salt stress (e.g., 0 mM, 50 mM, 100 mM, and 150 mM NaCl) on both PR and BRRI dhan28 were observed. Under salt stress condition, the shoot and root lengths of PR and BRRI dhan28 were decreased compared to control but the percent reduction of shoot and root length of PR was significantly lowered than that of BRRI dhan28; the number of live leaves per tiller was higher in PR than BRRI dhan28; the plant height of PR was significantly lower than BRRI dhan28. The results of biochemical analysis showed that the proline content in PR was higher in non-stress condition but was lower at 100 mM and 150 mM NaCl stress compared to BRRI dhan28. Catalase activity and anthocyanin content were significantly higher in leaves of PR than those of BRRI dhan28 in both salt-stress and non-stress conditions. Moreover, total chlorophyll content was higher in PR than BRRI dhan28 in control condition. Taken together, these results suggest that PR rice has higher salt tolerance potentiality than green rice (BRRI dhan28). J Bangladesh Agril Univ 19(1): 53–60, 2021 https://doi.org/10.5455/JBAU.51377

other Available Cattle Genotypes in Mymensingh District
Authors: Apurba Adhikary, Mohammad Mahbubul, A.K. Fazlul Haque Bhuiyan, Md. Azharul Hoque
Pages: 61–6 - 61–6
Abstract: The study was conducted to evaluate the reproductive performance of Brahman crossbred females and compare them with other available cattle genotypes found in Mymensingh district. Reproductive performance data on 35 Brahman crossbreds, 32 Indigenous, 12 Sahiwal crossbreds and 21 Friesian crossbreds were collected from three different villages (Baera, Bhabkhali and Dowhakhola) adjacent to Bangladesh Agricultural University, Mymensingh. Statistical analyses were performed using Statistical Analysis System (SAS) computer program. Reproductive performance of Brahman crossbred was recorded as age at first service: 32.29 ± 1.46 months, age at first calving: 42.00 ± 1.49 months, service per conception: 1.7 ± 0.17, overall conception rate: 0.76 ± 0.05 (76.11%), conception at first service: 0.63 ± 0.08 (62.85%) and gestation length: 282.97 ± 0.78 days. Highly significant (p<0.001) effect of genotype was observed for age at first service and age at first calving; conception rate at first service differs significantly (p<0.05) among genotypes while service per conception, overall conception rate and gestation length were not significantly affected by genotype. Reproductive performance of Brahman crossbred heifer is within the moderate range and better for some traits (i.e. age at first service) than the other genetic groups studied (i.e. Indigenous, Sahiwal × Indigenous, Friesian × Indigenous).

Pages: 67–7 - 67–7
Abstract: Gastrointestinal nematode infections of livestock are ranked in the top twenty diseases affecting small-holder farmers’ livestock. Mecistocirrus digitatus is one of the most prevalent parasitic nematode among the trichostrongylids causing severe health hazards leading to production losses in cattle worldwide. This study was conducted to explore the existence and genetic diversity of M. digitatus parasite populations from cattle characterizing second internal transcribed spacer (ITS-2) gene of nuclear ribosomal DNA (rDNA). A total of 23 adult Mecistocirrus parasites were collected from abomasa of slaughtered cattle from Mymensingh district of Bangladesh. After the extraction of DNA from adult parasites, ITS-2 of nuclear rDNA gene was amplified and sequenced. The edited and aligned sequences were employed for analysis to determine sequence variation and genetic diversity. All the sequences were found to have high identical ratio with M. digitatus of a published sequence and sequence identities ranged from 97.9% to 100%. Genetic analysis revealed 3 distinct ITS-2 genotypes among the M. digitatus isolates. The nucleotide and genotype diversities were 0.00089 and 0.170, respectively for ITS-2 sequences. Phylogenetic analysis (neighbour joining, maximum likelihood and maximum parsimony) of ITS-2 sequences indicated the existence of a single cluster within M. digitatus population in the study area. In conclusion, our study could confirm M. digitatus in the analyzed parasite isolates by amplifying and sequencing ITS-2 gene. Most of the isolates from our present study presented identical genotypes indicating that low genetically diversified parasites are circulating in Mymensingh region of Bangladesh. The findings of our study creates a basis for further molecular epidemiological surveys applying more M. digitatus parasite isolates from different regions of Bangladesh.

- The Quality Determination of Broiler Chicken Thawed Using Different
Techniques
Authors: Ahamed Rifath, Fathima Jemziya
Pages: 78–8 - 78–8
Abstract: The freezing technique has been used for thousands of years for the preservation of meat. The frozen meat has to be thawed before further processing. Quality deterioration occurs during the thawing process. The uniform-sized broiler chicken samples were individually frozen using an ultra-low temperature freezer (-40°C) for an overnight. The frozen meat samples were thawed in the refrigerator (4°C), cool room (20°C), hot air oven (60°C), tap water (27±5°C), and hot water conditions (40°C) until core temperature of the meat reaches 10°C in all method except refrigeration method where the core allowed to reach 4°C. Moisture content (MC), water holding capacity (WHC), drip loss (DL), cooking loss (CL), and pH were determined. There were significant differences (p<0.05) observed among the quality parameters of the samples, including MC, DL and CL based on the different thawing methods. However, there were no significant deviations in the pH and WHC. The sensory evaluation was also carried to evaluate color, taste, flavor, chewiness, juiciness and overall rating of the uniformly cooked samples by using nine hedonic scale techniques. There were no significant differences among sensory parameters of the samples (p<0.05). Of which, the highest rating was obtained for the cool room and tap water method, while the poor rating was for the refrigeration method. Therefore, the different thawing methods impact on the quality parameters of the frozen broiler chicken rather than influencing the sensory qualities. However, the cool room thawing method had minimized reductions in the qualities of the thawed broiler chicken followed by the tap water method.

Abstract: The study was carried out on milk clotting activity of the crude proteolytic enzyme (papain) from different parts of papaya plant (Carica papaya). Cottage cheese was prepared using whole cow milk collected from Bangladesh Agricultural University Dairy Farm. Diluted papaya latex (4 drops in 100 ml distilled water) was added and thoroughly mixed for coagulation of milk from different parts of the papaya plant. The treatment samples were named as A: mature papaya; B: immature papaya; C: papaya tree leaf; D: lower part stem and E: upper part stem. In case of organoleptic evaluation, it was observed that differences in scores for flavor, body and texture, finish, color, and total score were insignificant (p>0.05). In chemical analysis, significant (p< 0.05) differences were found in total solids, fat and ash contents among the different type of cheese samples. The highest total solids was found in samples B (56.24%) where the highest protein (30.97%), carbohydrate (9.30%), fat (22.67%) and ash (2.90%) content were observed in samples C, A, E and C, respectively. On the other hand, the lowest (p<0.05) acidity (0.73%) was recorded in sample B. Finally, it was evident that latex (papain) from different parts of papaya plant can be used in cottage cheese preparation.

Abstract: Preparation of wastelage by ensiling wet rice straw treated with cow dung (CD) and molasses was performed to improve the nutritional value as a quality feed for ruminants. Three different treatments were used as T0 (10% cow dung and 85% wet rice straw), T1 (20% cow dung and 75% wet rice straw), T2 (30% cow dung and 65% wet rice straw), and T3 (40% cow dung and 55% wet rice straw) with 5% molasses based on DM in each treatment to explore physical quality, chemical composition, in-vitro organic matter digestibility (OMD) and metabolizable energy (ME) contents at five different ensiling periods of 0, 30, 45, 60 and 90 days. The use of cow dung and molasses in wet rice straw improved the physical quality, nutritive value, and preservation quality of wastelage. The highest DM, CF, and EE were observed as 41.83%, 18.51%, and 2.88% respectively in T0 and CP was highest as 10.55% in T3 followed by T1 and T2. After ensiling, DM, ash, CF and EE were declined in all of the treatments but the increase of CP content was observed significantly (P<0.05) with increasing the ensiling period from 0 to 90 days. The OMD and ME contents were improved in T1, T2, and T3 compared to T0. The highest OMD and ME values were observed in treatment T3 which were 48.46% and 8.78 MJ/Kg DM, respectively and the lowest values were in (T0) were 38.31% and 7.57MJ/Kg DM respectively. Therefore, proper ensiling of rice straw with CD and molasses can provide an inexpensive, quality of feed and also reduce the waste hazards in our environment.

- Seasonal and Off-seasonal Vegetables Production in Maulvibazar District:
Insight from Profitability, Price Variations and Risk Management
Perspective
Authors: Sadek Ahmed Maruf, Jasim Uddin Ahmed, Jahangir Alam Khan
Pages: 99–1 - 99–1
Abstract: The research work was conducted to assess the comparative profitability, seasonal price variations and risk management strategies in seasonal and off-seasonal vegetables production by means of tomato and bean vegetables in Maulvibazar district. Both primary and secondary data were used. The study utilized tabular, mathematical and statistical techniques for data analysis. The study found that the BCR for the seasonal and the off-seasonal tomato production were 1.59 and 2.23, respectively, whereas the BCR for the seasonal and the off-seasonal bean production were 1.32 and 2.19, respectively. The study also found that, in season (November-March), the highest seasonal price index for both tomato and bean vegetables were found in November (i.e. 149.71 and 109.24, respectively). While in off-season (April-October), the highest seasonal price index for the tomato (i.e. 177.93) and the bean (i.e. 197.80) were found in September and August, respectively. In evaluating the risk management strategies, the study found that the frequency and the relative frequency of the application of manure and the use of insecticides were 100% for both season tomato and bean vegetables. On the basis of the findings and opinions of farmers during field visit, the researchers’ identified high cost of human labor, price fluctuation and deficiency of farmers’ awareness in term of different risk management strategies were the major problem. The researchers’ recommends that farmers should use friends’ contributory labor, planning appropriate harvesting period (i.e. early period for season and late period of off-season) and increasing farmers’ awareness by means of local and national level training. These findings will be helpful for farmers, researchers and policy makers to take informed production decision, formulation of future research work and policy development focusing vegetable sector of Bangladesh.

Growers’ Perception
Authors: Md. Abdur Rakib, Md. Zulfikar Rahman, Md. Asaduzzaman Sarker, Md. Masud Rana
Pages: 109– - 109–
Abstract: The main purpose of the study was to find out the extent of use of flood prone lands into mango production by planting different mango varieties, to find out the cause and effect of transformation of flood prone lands into mango production, to measure perception of the growers about using flood prone lands to mango production and explore the relationships between the selected demographic characteristics of the farmers and their perception of using flood prone lands to mango production. The study was conducted in four villages of Shibganj upazila under Nawabganj district. The sample size 80, randomly selected from a population of 400 mango growers. Interview schedule was used to collect data. Data were collected personally during 25 July to 15 September, 2015. Pearsons’ product moment correlation co-efficient (r) was computed to explore the relationships between the selected characteristics of the mango growers and their perception on using flood prone lands to mango production. The main three causes of transformation of flood prone lands to mango production were: Mango provides more earning than field crops, the neighbours and other land owners who planted mango trees serve as facilitators for others to follow the same and mango plants once planted give good return for several years; but in case of other crops, one has to grow crops every year. The most important effects of mango cultivation were found: Mango cultivation maintains environmental balance, it helps in earning more money and provide bio-fertilizer by the fallen leaf. The majority (78.75%) of the mango growers possessed high positive perception about mango growing in the flood prone area while 20% had moderate perception about transformation of flood prone lands to mango production. Among the 11 selected socio-economic characteristics of mango growers, eight (08) characteristics namely education, annual income, farm size, cosmopoliteness, media exposure, organizational participation, innovativeness and knowledge on mango production had positive significant relationship with their percerption of using flood prone lands to mango production. The mango growers mentioned a number of problems as well as probable solutions in transformation of flood prone lands to mango production. By taking proper and timely initiatives the transformation process should be enhanced to ensure sustainable quality mango production and socio-economic development of mango growers.

Pages: 119– - 119–
Abstract: The present study was conducted to analyze various socio-economic aspects of households with migrant and non migrant, influencing factors of labour migration and the impact of remittance on agricultural production. This study was conducted in two upazilas of Bogra districts namely Gabtoli and Shahjahanpur. The study areas were selected purposively. A sample of 60 respondents was being chosen purposively; 30 from households with migrant and 30 from households without migrant. Logistic regression model was used to measure the influencing factors of labour migration. Educational level of household head, household size, land size and household higher educated person of the selected household had a significant impact on labour migration in the research areas though the land of the household had a negative impact on labour migration. Descriptive statistics were used to measure the impact of remittance of the household with migrant. The average annual agricultural income (crop farming) of household with migrant is higher than household without migrant. The migration had brought positive changes in different types of livelihood assets. This study recommends that policy makers should create a more enabling economic environment and to provide procedural and structural support to the migrant workers to accrue the benefits of labour migration in relation to the country’s overall development.

Abstract: The study was carried out to examine participation of women in small ruminant rearing and household decision making process at Banshkhali Upazila in Chattogram. Four villages were purposively selected based on the density of small ruminant rearing. Data were collected from 50 households using random sampling method with a structured questionnaire. Descriptive statistic, Participation Index and Logistic Regression Analysis were used to analyse the data. The results of the study showed that (36%) young women were engaged in small ruminant rearing (26-35 age group) and major proportion of the respondents (46%) in the study areas were primary educated. About 52% of the respondents have a family size consisting of 6-10 members. Nearly half (46%) of the women involved in rearing small ruminants earned between BDT 12,000.00 - BDT 18,000.00 per annum. The participation index implies that large proportions of women were always participating in supplying water, feeding and providing fodder and cleaning barns/corrals/pens of small ruminants. Moreover, they were rarely participating in construction of house/barns/corrals/pens, rearing in confinement/partial-confinement/free ranges system and bringing animal to veterinary surgeon for vaccination purpose. In household condition, women involved in decision making for rearing livestock, marriage of children whereas rarely participate in activities such as selection of variety and inputs for agricultural production, education of children, purchase of household assets and have minimal participation in selling household assets, freedom of mobility. A logistic regression analysis revealed that women’s participation in household decision making process was negatively related with family size and farm size, but positively related with respondent’s income (P<0.05) and education (P<0.01). It may be concluded that higher the education and income of women, more the tendency of making household decisions alone.

Pages: 134– - 134–
Abstract: Biogas originates from bacteria in the process of biological breakdown of organic material under anaerobic conditions. Biogas can be produced from biodegradable substrates such as agricultural waste, cow dung, municipal waste, plant material, sewage, green waste or food waste. The study was conducted to augment biogas production efficiency under different feeding interval. The objectives were measured biogas production, estimate major components (Ambient Temperature, pH, CH4, CO2), measure the biogas production efficiency under different ambient temperature and pH. Two digesters were installed to digest cow dung, where one set-up was used for digestion of cow dung by regular feeding and other set-up was used for digestion by 4-day interval feeding. The digester was made up of PVC of 7.5 m3 capacity while gas holding capacity was 2 m3. 50kg cow dung and 50 L water was used at 1:1 ratio for regular feeding. In 4-day interval, 200 kg cow dung and 200 L water was used at 1:1 ratio. The digesters were operated at ambient temperature 25-350C. The pH ranges from 6.5-7.5. The ambient temperature and pH maintained good range for gas production. The overall biogas yield for feeding in 4-day interval was 34% higher compared to regular feeding as well as there was a significant difference from regular feeding. The methane yield was 28% more in 4-day interval feeding. 48 kg of cow dung would be necessary to produce 1 m3 of biogas in praxis as usual and 32 kg feeding in 4-day interval. In both setups, the digesters could produce enough biogas to cover daily theoretical demand (0.8-1.6 m3) for preparing 2 meals for the average family size in Bangladesh.

Bangladesh
Authors: Md. Shariot-Ullah, Sk. Tazbir Rahman, Md. Touhidul Islam, Md. Sifat Siddik
Pages: 143– - 143–
Abstract: This study was carried out to observe the spatial-temporal pattern of monsoon rainfall, acting as one of the major contributors to Bangladesh's water resources, particularly for agricultural purposes. Daily rainfall and prevailing wind speed for the period of 1986 to 2015 (April to November) of Dinajpur, Bangladesh were collected and analyzed to identify the trend, shifting pattern, and the past and probabilistic future arrival and withdrawal dates for 1 year out of 4, 10, and 25 years. It was revealed that the arrival and withdrawal dates were fluctuating between May to June and August to November, respectively. The mean arrival and withdrawal dates were evident on 3 June, and 27 September, respectively, and most of the dates were in the defined range of June to September. The early arrival dates were between 1 – 53 days except in 1992 (30 days later), and the late withdrawal dates were between 1 – 69 days except in 1987 and 2009 (5 and 10 days earlier). Finally, it was saliently appeared that the probabilistic early (21 May, 9 May, and 30 April) and late (12 June, 29 June, and 8 July) arrival dates are depicting the overall early start of monsoon, while the probabilistic early (13 September, 1 September and 23 August) and late (10 October, 22 October, and 1 November) withdrawal dates are representing the delayed overall withdrawal of monsoon rainfall in the targeted domain. To conclude, the findings of this study would be worthwhile for agricultural and regional planning purposes and, furthermore, for the management of floods and water resources in the North-western region of Bangladesh.

- Well-being Status of Fishery Stakeholder Groups: A Comparative Study
Between Improved and Poor Fish Handlers in Haor and Floodplain
Authors: A. K. M. Nowsad Alam, M. U. M. Abu Zakaria, Md. Khaled Rahman, Al-Shahriar, Mohammad Nuruzzaman
Pages: 152– - 152–
Abstract: This study presents a comparative analysis of well-being status between improved fish handler (IHs) and poor fish handler (PHs) groups of Kishoreganj haor and Daudkandi floodplain. Two hundred seventy respondents were surveyed randomly through structured questionnaires, focus group discussion (FGD) and key informant interview (KII) from July, 2018 to October, 2019. Young people (11-30-year group) were dominant in both the two stakeholder groups in haor and floodplain. Most of the stakeholders belonged to medium size family (5-8 persons) in both the groups. Access to education, electricity, kitchen, housing and sanitation facilities were comparatively better in IHs than PHs in both haor and Daudkandi floodplain fisheries (DFPF). In Kishoreganj haor, higher number of IHs possessed above 12 decimal of homestead land. The quality of life was comparatively better in IHs than PHs. About 45% IHs and 48.89% PHs in haor areas received health service from the Government hospitals, while it was 38.57% and 52% in DFPF, respectively. Monthly income and yearly savings were higher in IHs than PHs in both study areas. Lack of proper knowledge on pre-harvest, harvest and post-harvest handling practices of fish from fishing to transport into retail markets were found to be the major constraints of poor quality and low price of fish. IHs had comparatively better well-being status than the PHs. It is, therefore, suggested that improved fish handling must be practiced by all the stakeholder groups to improve their well-being status.

Pages: 160– - 160–
Abstract: The present study focused on the use of extra-label drugs in commercial aquaculture. Data was collected through questionnaire interview with 30 drug retailers and 30 commercial aqua farmers in Mymensingh Sadar and Trishal upazila of Mymensingh district. All together 94 extra-label drugs of different groups were identified which included antibiotics, disinfectants, nutritional supplements, probiotics, gas remover and saline. Six groups of antibiotics having 10 different active compounds with 46 trade names were found in the drug retailer shops. These drugs were primarily prepared either for the use in veterinary or poultry but were found using indiscriminately in aquaculture. All these drugs were marketed by 18 companies in the study areas. It was observed that 83% drugs were not labeled for aquaculture purpose. Majority (77%) of the commercial aqua farmers used extra-label drugs in their farms and 73% of them never received any prescription from qualified personnel before use. Most of the farmers were unable to calculate appropriate doses and had no idea about risk, safety issue and toxicity reaction of using extra-label drugs. Farmers generally got suggestion from the drug retailer regarding application of drugs. The results also revealed that extra-label use of veterinary and poultry drugs in aquaculture is a common practice by commercial aqua farmers. Thus, the use of drugs in aquaculture should have a sufficient regulatory system in place. It is important to produce and use appropriate labeled drugs under a sufficient regulatory system for safe fish production in the aquaculture of Bangladesh.
