This experiment “determination on efficacy of common selected water quality treatment drugs and chemicals used in aquaculture in Bangladesh” was conducted for two months in pond at Freshwater Station Mymensingh, BFRI. Experiment was designed into four treatment (T1 -Timsen, T2 -Geofersh, T3 -Geoprime, and T4 –Geotox, Recommended dose of the company was used for treatment), with three replications. This experiment was conducted by using twelve ponds having an area of 40.00 m2 each & average depth was 1.2 m. Twelve ponds were prepared through liming @ 250 kg/ha after drying of pond. After 5 days of liming each of the following drugs Timsen, Geofresh, Geoprime, Geotox was used for each pond. After 3 days of using drugs fingerlings of Gift Tilapia, (ABW: 6.25 ± 0.27 gm), were stocked in all the ponds with same stocking density of 100 fish/pond. Feeding fingerling was maintained twice daily in the morning & evening with commercial Saudi-Bangla feed at the rate of 10% of the body weight in the first week. For second week daily ration was adjusted at the rate of 5% of the body weight. Data on water quality parameters, survivality, and growth were recorded before and after using of drugs. Essential water quality parameters were recorded weekly and growth, survivality were recorded after ten days interval. Histological studies were done 1 month’s interval. It was observed that after using drugs in all treatments the value in case of Timsen pH (8.12±0.58), alkalinity (119.40±9.67), nitrate (0.28±0.04) and phosphate (1.00±0.19), dissolved oxygen (4.56 ± 0.29), were maintained. Ammonia became reduced due to use of drugs. During observation of physical water quality parameters transparency (31.27±3.06) became increased and temperature (28.25±3.38) became lower than control water body. Net production of Gift Tilapia (1955.6 4± 24.28 kg/ha) also provided higher in Timsen treated pond than other treated ponds. Timsen treated pond provided higher tilapia production due to water quality of Timsen treated pond was more optimum than other drugs treated ponds. Histopathological study did not show any negative changes on the organ of fishes. Among all the drug, Timsen was the best in all aspects (improve tilapia fish health and water quality). Other three drugs (Geo-tox, Geo-fresh, and Geo-prime) resulted more or less same result.

The research was conducted for 120 days from 01 March 2019 to 30 June 2019 at Saver, Doshaid the peri-urban area near Dhaka city. The objective of the study was to assess the growth performances of tilapia and vegetable production in the wish pond and wish pond-aquaponics systems. The initial length and weight of tilapia juvenile (Oreochromis niloticus) of 5.17±0.14 to 5.15±0.12cm and 3.24±0.30 to 3.35±0.13g were stocked at the rate of 200 fish/m3 pond area in wish pond aquaponics and wish pond system, respectively. The Brinjal, chilli and mint were planted in both wish pond and wish pond-aquaponics systems. A commercial floating pellet feed of 30% protein was fed the fish at the rate of 5% body weight twice daily. Both the wish pond-aquaponics and wish pond waster was aerated with air pump and stones. The wish pond-aquaponics water was filtered through the vegetable media but wish pond water was not such filtration system rather partial water change was done in each month. The survival rate and total production of fish were higher (89.17±3.82%, 34.88±2.22 tons/ha/120 days) in wish pond-aquaponics system than the wish pond system (76.67±2.08, 26.33±0.87 tons/ha/120 days). Moreover, the vegetables production was also found higher in wish pond-aquaponics system (Brinjal 40.97±5.25, Chilli 9.54±0.84 and Mint 12.81±1.22) than the wish pond system (Brinjal 30.58±2.06, Chilli 7.92±0.16 and Mint 10.08±0.29). Water quality and nutrient utilization was comparatively better in wish pond-aquaponics system as the water was filtered by brick lets and plant roots and nutrients utilized by the plants which was absent in wish pond system. Therefore, the wish pond-aquaponics system performed better than the wish pond system and proved the system is environmental friendly and sustainable.
该研究于2019年3月1日至2019年6月30日在达卡市附近的城郊地区Saver, Doshaid进行了120天的研究。本研究的目的是评估罗非鱼的生长性能和蔬菜生产在祝愿池和祝愿池-水培系统。以200尾/m3池面积放养罗非鱼幼鱼(Oreochromis niloticus)，初始长度为5.17±0.14 ~ 5.15±0.12cm，初始体重为3.24±0.30 ~ 3.35±0.13g。茄子、辣椒和薄荷都种植在许愿池和许愿池-水培系统中。每日2次，按5%体重投喂蛋白质含量为30%的商业浮动颗粒饲料。许愿池水培和许愿池污水均采用气泵加石曝气。希望池-水培水是通过蔬菜介质过滤的，但希望池水不是这样的过滤系统，而是每月进行部分换水。鱼体成活率(89.17±3.82%)和总产量(34.88±2.22 t /ha/120 d)高于鱼体成活率(76.67±2.08,26.33±0.87 t /ha/120 d)。此外，祈愿塘-水培系统的蔬菜产量(茄子40.97±5.25，辣椒9.54±0.84，薄荷12.81±1.22)也高于祈愿塘系统(茄子30.58±2.06，辣椒7.92±0.16，薄荷10.08±0.29)。许愿池-水培系统的水质和养分利用率相对较好，因为水是由砖瓦和植物根系过滤的，植物利用的养分是许愿池系统所没有的。因此，愿望池-水培系统的性能优于愿望池系统，证明了该系统的环保性和可持续性。

This study aimed to understand the degradation pattern of cattle manure with different types of bulking materials during composting. For this purpose, a composting experiment was conducted with three bulking materials e.g., T1 (composting with dry chopped straw), T2 (composting with dry tree leaves) and T3 (composting with saw dust) with 3 replications. Parameters studied were dry matter (DM), organic matter (OM), ash, organic carbon (OC), total nitrogen (TN), crude fiber (CF), carbon nitrogen ratio (C/N) and pH at different days of intervals. Results showed that the bulking materials have a significant influence on the quality of the final compost. The highest DM content was observed in T3 (48.17%) and the lowest DM content was observed in T2 (38.36%) after 45 days of composting. There were significant (p<0.01) higher reduction rate of OM, OC and CF were found in T3 compared to T1 and T2 and the differences were also significant (p<0.01) among days intervals over 45 days of experimental period. TN content gradually decreases with the increase of time. But there was no significant difference in TN alteration among the treatments along with time intervals. There were significant differences (P<0.01) in C/N among treatments and a gradual increment of C/N was found with the advancement of the composting operation. There was a little change in pH of all the treatments but those treatments were not followed a trend during the total experimental period. Finally, it may be concluded that CF and OM degradation rate is faster in T3compared to T1 and T2. These might be indicated that saw dust might be used as an efficient bulking material that enhances OM degradation during composting of cattle manure.

The experiment was conducted to investigate the livelihood improvement of farmers through cattle fattening in selected areas (Mymensingh Sadar and Fulbaria Upazilla) in Mymensingh district of Bangladesh through field survey. Total of 30 respondents were randomly selected from the three villages. Each village consists of 10 respondents. Data were collected from randomly selected 30 farmers who were involved in small scale cattle fattening through personal interviews. The selected characteristics were the socio-economic conditions of the farmer such as age, level of education, occupation, household size, land size, source of capital, family income from cattle fattening, farm size, etc. The respondents were aged from 25 to 60 years. The highest proportion (56.7 percent) of farmers was in the middle-aged. The education levels among the respondents were 46.7 percent illiterate, 33.3 percent primary level, 13.3 percent up to S.S.C level and 6.7 percent of H.S.C or above. Among the respondents, 33.3 percent were involved in cattle fattening as primary occupation and 67.3 percent were involved in cattle fattening as a secondary occupation. About 83.3 percent of respondents were used own capital for fattening purpose and 16.7 percent respondents had bank loan or NGO loan facilities for fattening purposes. The income of the respondents’ family from cattle was BDT 11283.33 which was contributed 31.39 percent to the increased family income. The results show that cattle fattening could be the most suitable way to increase the socio-economic status of the poor farmers in terms of net income.

Effects of pesticide exposure on public health are monitored in developed countries, which is rare in the least developed countries like Bangladesh. Here, a surveillance study was conducted to investigate the farmer's knowledge and perception toward pesticide use and the impact of occupational exposure as well as an environmental hazard in six agro-based districts (Gazipur, Khulna, Manikganj, Naogaon, Mymensingh and Tangail) in Bangladesh. A questionnaire was designed for a face to face interview of the farmers (at least 100 farmers in each district), and the data was collected. The farmer during cultivations used pesticides as single, double or several times in a single crop cycle. Among different types of pesticides, insecticides were highly used (38%), whereas Imidacloprid, and Lamda cyhalothrin insecticide was top used by the farmers. Weedicides or herbicide, fungicides and rodenticides were used 11%, 48%, and 0.5%, respectively. The knowledge and perception of the farmers towards pesticide usage are minimum, whereas the environmental pollution aspect is deficient. The knowledge of using personal protective equipment is the least. Eighty five percent of farmers use pesticides by spraying in the field. Thirty nine percent of farmers suffered from sneezing, burning sensation on face, conjunctivitis, dizziness and headache during pesticide application, and 3% suffered from skin rash of long time exposed with pesticide. The exposure of pesticides is widespread in the professional life of a farmer in Bangladesh. So, it is essential to ensure different training and awareness building program for the farmers to cope the adverse situation.

This study was aimed to determine the productive and economic performances of two different genotype egg producing chicken farms carried out with good, fair and poor bio-secured intervention in the south western region of Bangladesh. The world class Hisex White and Hisex Brown layer strainwas used as egg type chicken. According to obtain marks each of one hundred (total two hundred) surveyed farms were divided into good (≥ 80%), fair (61-79%) and poor (≤ 60%) bio-secured categories. Highest numbers of Hisex White (41%) farms but lowest numbers of Hisex Brown (29%) farms were reared under good biosecured condition in the study area. Under good bio-secured level Hisex White and Brown was taken highest amount of feed and produced highest number of eggs. The average egg weight and egg mass of both Hisex White and Brown was not differed significantly (P>0.05) under good, fair and poor bio-secured farms respectively. Under good bio-secured farms FCR value was better than fair and poor farms respectively. Highest percentage of survivability occurs in good and lowest in poor bio-secured condition, both white and brown layer strain. The BCR of Hisex White was found highest (1.13) under good but similar (1.12) under fair and poor bio-secured farms and did not differed significantly (P<0.01). However, the BCR of Hisex Brown was found highest value (1.17) under different bio-security level. This result revealed that the Hisex Brown was less biosecurity sensitive and highly profitable than that of Hisex White farms.

Analyzes revealed that growth in the area for Aus, Aman, and Boro rice slowed in the period 1971/72-1983/84, but surprisingly the production growth accelerated due to amazing technological advancements and the implementation of government subsidies on complementary inputs. Applying the Nerlovian supply response model, the result showed that, lagged area for Aus, Boro, and wheat was positive and significant, implying that the preceding year area under Aus, Boro, and wheat had a significant influence on land allocation for the following year. The lagged relative yield of Boro and Aus turned out positive implying that in Boro season farmers took into consideration the lagged relative yield of Boro vis-a-vis wheat in the allocation of land for Boro rice and wheat cultivation. The negative price risk variable further implied farmers’ risk aversion response towards price fluctuation. The yield risk variable was found negative for Boro and wheat, implying that this factor did not influence the cultivation of these two crops. Meanwhile, although Bangladesh achieved marginally food security, government and policymakers should focus on stabilizing the market price at harvest time to realize sustainable food security in the future, and researchers should prioritize breaking the yield ceiling as well as developing different stress-tolerant varieties. In the same way, steps should be taken through public and private partnerships to disseminate different crop varieties so that productivity could be enhanced at the desired level.

Application of silicon (Si) influences the stress resistance, and thereby could boost up the growth and yield of rice. An experiment was conducted to investigate the effect of Si fertilization on rice cv. Binadhan-8 at ambient and elevated temperature during Boro season of Bangladesh. Significant differences were observed in the studied parameters: plant height, SPAD reading, yield and concentration of NPK in grain and straw of rice. At ambient temperature (AMT) condition, plant height, SPAD reading, grain and straw yield were also the highest in case of 10 g pot-1 Si application. Moreover, the highest NPK contents in grain and straw were observed in the application of Si @ 10 g pot-1, whereas the lowest NPK contents were mostly recorded in control (0 g Si pot-1). The increased rate of Si contributed to the NPK absorption in grain, yield attributes and yield of rice up to 10g pot-1 Si application. On the other hand, yield contributing characters, grain yield and NPK uptake were showed a similar response to Si application at elevated temperature (ELT). But, the yield contributing characters as well as grain yield at ELT showed less performance in comparison to AMT. Therefore, the application of Si could be recommended to optimize the yield attributes, yield and NPK uptake of rice.
硅的施用影响了水稻的抗逆性，从而促进了水稻的生长和产量。通过试验研究了施硅对水稻cv的影响。在孟加拉国的Boro季节，Binadhan-8在环境和高温下。水稻株高、SPAD读数、产量、籽粒和秸秆氮磷钾浓度均存在显著差异。在室温条件下，施硅量为10 g时，植株高度、SPAD读数、籽粒和秸秆产量均最高。氮磷钾含量在施用10 g Si -1时最高，在对照(0 g Si -1)时最低。施硅量的增加对水稻氮磷钾的吸收、产量性状和产量都有促进作用。另一方面，增产性状、籽粒产量和氮磷钾吸收在高温施硅(ELT)下表现出相似的响应。但在产量贡献性状和籽粒产量方面，ELT的表现不如AMT。因此，可以推荐施用硅来优化水稻的产量属性、产量和氮磷钾吸收。

This experiment was conducted to find out the effect of different salt concentration on quality and storage stability of beef patties. For this purpose beef patties samples were kept as fresh, refrigerated and frozen condition. Then the fresh, refrigerated and frozen samples were divided into four subdivisions. These are 0% salt concentration, 1.5% salt concentration, 3.0% salt concentration and 5.0% salt concentration. These samples were stored at (23-25)˚C, 4˚C and -20˚C temperature for 60 days and were analyzed on 0 day, 7th day, 14th day, 21th day in refrigerated condition at 4˚C, and 0 day, 15th day, 30th day, 45th day and 60th day in frozen condition at -20˚C. Dry matter content of all the samples increased with the advancement of storage time & salt concentration and temperature in refrigerated & frozen condition (P < 0.01). Beef patties containing 5% salt & stored 21 days resulted higher dry matter in refrigerated condition (P < 0.01). Dry matter of beef patties was higher when salt containing 5% & stored 0 day in frozen condition. Ash was increased with the increased of salt concentration in both refrigerated & frozen condition. It was decreased with increasing day in both conditions. Ash % was higher at salt containing 5% & 0 days stored sample in refrigerated condition (P < 0.01). In frozen condition ash % of beef patties was higher when salt containing 5% & stored 15, 30 & 45 days. Crude protein content of all the samples increased with advancement of salt concentration but decreased with advancement of storage time in both condition. CP % was higher at salt containing 5% & 0 days stored sample in refrigerated condition. In frozen condition CP% of beef patties was higher when salt containing 3% & stored 0 day (P < 0.01). Salt concentration had no effect on EE & storage time had little effect on EE of beef patties. EE% of beef patties containing 0% salt & stored 0 day provided higher EE in refrigerated condition & it had no effect on frozen condition (P < 0.01). pH was increased in refrigerated condition with increasing salt% & decreased in frozen condition with decreasing salt%. pH was decreased with increasing days in refrigerated & frozen condition. pH of beef patties containing 0% salt & stored 0 day provided higher pH in both condition. Cooking loss was higher with lower salt concentration in refrigerated & frozen condition. Cooking loss was higher with higher storage time both refrigerated & frozen condition (P < 0.01). Cooking loss of beef patties was higher when salt containing 0% & stored 21 days in refrigerated & 60 days in frozen condition (P < 0.01). According to proximate composition sample containing 5% salt & stored at higher days provided higher DM%, CP% and ash%. The sensory based on firmness ,color, flavor, texture, tenderness, juiciness, chewiness, softness, hardness, taste and overall acceptance of the warm meat patties were evaluated by a trained sensory panel (N = 5).
