A field experiment was conducted at the research field of HSTU, Dinajpur during November 2019 to March 2020 to find out the effect of irrigation frequency on the growth and yield of Soybean (Glycine max L.) cv. BARI Soybean-6. The experiment was carried out with a RCBD with four replications of irrigation treatments viz, I0= no irrigation (control), I1= one time at 20 days after sowing (DAS), I2= two times (20 and 40 DAS), I3= three times (20, 40, and 60 DAS). At 105 DAS the highest plant height (52.53 cm) was found from I2 treatment and the shortest plant (45.82 cm) from I0 treatment. The highest (5.91) leaf area index was obtained from the treatment of three irrigation (I3) at 90 DAS and the lowest (5.1) leaf area index from the control (I0). At the 90 DAS highest nodule number (9.208) and the lowest nodule number was (6.459) recorded from I3 and I0, respectively. The highest (90.09 g) fresh weight was obtained from the treatment I2 at 90 DAS and the lowest (65.64 g) was recorded in I0. I3 produced the highest amount of dry matter of (29.50 g) and the lowest amount of dry matter production at harvest (20.67 g) in I0 treatment. The highest seed yield was observed from I2 (1.638 t ha-1 ) which was statistically similar with I3 whereas, the lowest obtained from I0 (1.075 t ha-1 ). The highest small stover yield was obtained from I3 (1.759 t ha-1 ) which is statistically similar to I2 (1.754 t ha-1 ) whereas the lowest was observed from I0 (1.540 t ha-1 ) which was statistically similar to I1 (1.566 t ha-1 ). The highest biological yield was found from I2 (3.425 t ha-1 ) which is statistically similar to I3 and the lowest was obtained from I0 (2.56 t ha-1 ). The maximum harvest index was found from I2 (47.71 %) and the minimum was obtained from I0 (40.81 %). I2 treatment showed more significant results than the other treatment I0, I1 and I3. So, two times irrigation showed significant effect showed the highest yield of 1.638 t ha-1.
2019年11月至2020年3月，在迪纳杰浦尔HSTU研究基地进行了田间试验，研究了灌溉频率对大豆(Glycine max L.)生长和产量的影响。巴里Soybean-6。采用RCBD进行4个重复的灌溉处理，即I0=不灌溉(对照)，I1=播后20天1次(DAS)， I2= 2次(20和40 DAS)， I3= 3次(20、40和60 DAS)。105 DAS时，I2处理株高最高(52.53 cm)， I0处理株高最低(45.82 cm)。在DAS 90时，三次灌溉处理(I3)的叶面积指数最高(5.91)，对照(I0)的叶面积指数最低(5.1)。90 DAS时，I3和I0的结节数最高(9.208)，最低(6.459)。处理I2在90 DAS时鲜重最高(90.09 g)，处理I0鲜重最低(65.64 g)。I3处理收获时干物质产量最高(29.50 g)， I0处理收获时干物质产量最低(20.67 g)。I2籽粒产量最高(1.638 t ha-1)，与I3相近，I0籽粒产量最低(1.075 t ha-1)。小秸秆产量最高的是I3 (1.759 t ha-1)，与I2 (1.754 t ha-1)相似，最低的是I0 (1.540 t ha-1)，与I1 (1.566 t ha-1)相似。I2的生物产量最高，为3.425 t ha-1，与I3相似，I0的生物产量最低，为2.56 t ha-1。I2收获指数最高(47.71%)，I0收获指数最低(40.81%)。I2处理比I0、I1、I3处理效果更显著。因此，两次灌水效果显著，最高产量为1.638 t ha-1。

Currently in Bangladesh farmers use hand operated sprayer or motorized sprayer in agricultural fields. Generally in the agricultural field, traditional or conventional techniques like shoulder mounted spraying system have been used because it is cheaper, easy to use and less costly. Continuous use of traditional energy resources will have high risk of rising in price and energy depletion. Now-a-days there is a great need for ‘’conservation of energy’’ and application of renewable energy. This paper presents the design, development and evaluation of a solar powered spraying system. The specific objectives of this research is to design and fabricate the solar powered sprayer by considering parameters like desired spraying rate, low weight, low cost, faster coverage of area and high field efficiency. A two-nozzle sprayer was fabricated with MS bar frame and 4-wheel trolley with water level indicator which runs on power source as a DC battery (12 volt, 8.2 Ah) via solar panel and runs by a DC motor (12 volt, 2A). The entire unit is portable and is operated by one labor. The design mainly eliminates the shoulder mounting sprayer setup which causes back pain, uses of fossil power which is non-renewable and hazardous and extensive use of manpower. The machine was compared to conventional sprayer and found more efficient. Pump efficiency almost 83.33% found for single nozzle and 93.33% for double nozzle and the sprayer is 58% time saving than manual sprayer. The operating cost of the machine was 802 Tk ha-1 . Also found capital recovery factor, capital consumption and annual cost of the solar operated sprayer were 0.26, Tk 1520 and Tk 41665, respectively.

This paper attempts to depict the deteriorating socio-economic status of the indigenous community as an ethnic minority in Bangladesh. The study focuses on the poverty of the community, which is deprived by the majority of Bengalis. This is explained through a broad spectrum of issues that constructed the structure of the discrimination occurring against the community in Bangladesh. The article is based on an empirical study in Rangamati through a survey method using a structured questionnaire. The structure of poverty and its correlates thereof were explained following a systematic poverty measurement technique. The study includes measuring the Headcount ratio, Poverty gap, Squared poverty gap, and Gini- coefficient that made poverty rate and extent of poverty. The major findings reveal that the Chakma community is not only suffering from severe poverty but also faces discrimination and deprivation to a great extent. Results reveal that the Chakma community’s large extent of poverty is caused by belongingness to the minority group while the group has lower inequality or Gini-coefficient among the group. Based on the findings, the study suggests specific policy guidelines for comprehensive poverty alleviation programs in order to improve the socioeconomic conditions of the indigenous community in Bangladesh.

An experiment was carried out in the laboratory of the Mushroom Development Institute, Savar, Dhaka from July to December 2019 to determine the effect of the sawdust composting period on the yield and yield attributes of different oyster mushroom varieties. The experiment was laid out by following Completely Randomized Design (CRD) with three replications. Three varieties viz. V1 (Pleurotus djamor), V2 (Pleurotus ostreatus) and V3 (Pleurotus florida) with six different days of composted sawdust such as T0 (0 days), T1 (5 days), T2 (10 days), T3 (15 days), T4 (20 days), T5 (25 days) and T6 (30 days) were used in this study. The effect of different mushroom varieties and composted period of sawdust showed significant variation in growth and yield parameters. The results revealed that the highest number of the fruiting body, the effective fruiting body and biological yield were found in V2, whereas the lowest numbers were observed in V3. Besides, the maximum yield, the highest number of fruiting bodies and effective fruiting body were observed in T3. Moreover, the maximum yield (56.50 g) was produced by V2T3 combination, and the minimum yield (38.13g) was produced by V3T2. The highest biological efficiency (32.28 %) was obtained in V2T3, whereas the lowest biological efficiency (21.78%) was obtained in V3T2 sawdust. This study suggests that Pleurotus ostreatus and 15 days composted sawdust showed the best performance.

The application of smoke is a traditional practice to trigger the ripening process of banana. This experiment was conducted to investigate the effects of different post-harvest treatment on the physiochemical properties of banana fruits. This experiment was laid out in a Completely Randomized Design (CRD) with three replications, which constituted the seven treatments viz. control, low density polyethylene bag, as well as 12, 18, 24, 30 and 36 hours exposed to smoke. The results indicated that smoke treatment increased physiological weight loss and pulp weight during storage whereas decreased firmness, peel weight and dry matter content. Chemical parameters such as moisture, total soluble solid, and total sugar showed an increasing trend during the storage period, whereas acidity and vitamin C increased initially up to 5 days and declined thereafter during the ripening of the banana. Smoking for 18 hours resulted in uniform ripening with yellow coloration within 5 days, whereas untreated control fruits remained green for 5 days and ripened within 8 days after storage. The present study concludes that smoke treatment is a simple but quick means of banana ripening. Exposer of banana fruits to smoke for 18 hours produced better quality and improved the shelf life.
传统的做法是用烟熏来触发香蕉的成熟过程。本试验旨在研究不同采后处理对香蕉果实理化性质的影响。试验采用完全随机设计(CRD)，共3个重复，即对照、低密度聚乙烯袋处理以及熏蒸12、18、24、30、36 h 7个处理。结果表明，烟熏处理增加了贮藏期间的生理失重和果肉质量，降低了松紧度、果皮质量和干物质含量。水分、总可溶性固形物和总糖等化学参数在香蕉成熟期呈上升趋势，酸度和维生素C在成熟期前5天呈上升趋势，之后呈下降趋势。熏制18小时后，对照果实在5天内均匀成熟，颜色呈黄色，而未经处理的对照果实在5天内保持绿色，在8天内成熟。本研究认为烟熏处理是香蕉成熟的一种简单而快速的方法。香蕉果实在烟熏中暴露18小时，质量更好，保质期更长。

To investigate the ameliorative effect of foliar application of potassium and gibberellic acid on wheat to drought stress an experiment was conducted at the research field and laboratory of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur during the period of November 2018 to March 2019. The experiment was laid out in a split plot design with three replications. Four growing conditions viz. well water (WW), water deficit stress (WDS), foliar application of 2.23% K2SO4 under WDS and foliar application of 300 ppm GA3 under WDS were set up as the main plot treatment and two wheat varieties (Kanchan and BARI Gom-30) were set up as sub plot treatment. Non-irrigated water stress significantly reduced different physiological traits, yield and yield attributes except proline content of flag leaf of wheat, whereas foliar application of potassium and GA3 improved these traits under WDS. Foliar application of potassium improved biological yield (22.04% and 15.16%) and grain yield (3.19% and 2.59%) in Kanchan and BARI Gom-30, respectively, whereas foliar application of GA3 improved biological yield (12.12% and 17.00%) and grain yield (1.47% and 1.18%) in Kanchan and BARI Gom-30, respectively under WDS. Though, foliar application of potassium and GA3 ameliorated the adverse effect of drought on wheat but potassium was found more effective. Therefore, it may be concluded that additional foliar application of potassium along with recommended potassium could improve production of wheat under drought

The purpose of this paper is to determine customer satisfaction with corporate loans. Corporate lending in Bangladesh is making a large attitude. The assessment's primary goal is to conduct a thorough inquiry into the fulfillment of borrowers from Rupali Bank Limited. According to the review, Rupali Bank Limited has excellent employees in terms of behavior, and customer happiness is an important factor in evaluating the bank's performance. Using a self-administered survey, a confirmatory factor analysis, and a set of quality measures adopted from the existing literature. We reaffirm that factors of perceived satisfaction with regard to corporate loans in the context of Bangladesh include interest rate, information availability, policies and charges as well loan repayment procedure. For data analysis, factor loading through PCA and regression were applied. Results revealed that interest rate, information availability, policies and charges as well loan repayment procedure are positively related with customer satisfaction towards corporate loan. However, this study is a genuine contribution towards the corporate loan sector of Bangladesh. Our findings have relevance for academics and practitioners interested in understanding customers' ultimate needs.
本文的目的是确定客户对企业贷款的满意度。孟加拉国的企业贷款正变得越来越重要。评估的主要目标是对Rupali Bank Limited的借款人的履行情况进行彻底的调查。根据review, Rupali Bank Limited拥有优秀的员工行为，客户满意度是评估银行绩效的重要因素。采用自我管理的调查，验证性因素分析，并从现有文献中采用了一套质量措施。我们重申，孟加拉国对企业贷款的满意因素包括利率、信息可得性、政策和收费以及贷款偿还程序。数据分析采用主成分分析法和回归分析法进行因子加载。结果表明，利率、信息可得性、政策收费以及贷款偿还程序与客户对企业贷款的满意度呈正相关。然而，这项研究是对孟加拉国公司贷款部门的真正贡献。我们的研究结果对有兴趣了解客户最终需求的学者和从业者具有相关性。

A study was carried out at Bangladesh Rice Research Institute, Regional Station, Rangpur along with laboratory test and farmers field in Fulgachi, Lalmonirhat for field test during Aman season with BRRI dhan52 to identify the effect of plant spacing of transplanter on grain yield. Three levels of plant spacing (30 cm×13 cm, 30 cm×15 cm, 30 cm×17 cm), seedling density setting (Middle, Middle+1 and Middle+2) and RCBD with 9 plots were used for the purpose. In field experiment, three plant spacing and Middle+2 seedling density setting was used. In this walking type self-propelled rice transplanter, the field capacity, field efficiency and fuel consumption of the transplanter were 0.134 ha hr-1 , 68 % and 3.71 L ha-1 , respectively. Labor requirement for mechanical and manual transplanting were 6.75 man ha/hr and 223 men hour per hectare respectively. Cost of mechanical transplanting was Tk. 3291 per hectare as compared to Tk.13000 per hectare in case of manual transplanting. If the usage of this machine per year decreases, the operating cost per hectare will increase. From breakeven analysis with mechanical and manual operating cost, it was found that transplanter should use at least 11 hectares per year to minimize the operation cost per hectare. For 17 cm, 15 cm and 13 cm plant spacing, number of tray requirement were 218, 270 and 277 per hectare, respectively. Number of seedling tray saved for 17 cm and 15 cm spacing were 21 % and 2.53 % compared with 13 cm spacing. In 30 cm×17 cm spacing, minimum number of seedlings required maximum no. of tray saved. Grain yield in different spacing (30 cm×13 cm, 30 cm ×15 cm, 30 cm ×17 cm) and manual transplanting were 4.43, 4.97, 5.23, 4.13 t ha-1 , respectively. Results showed that, highest grain yield among plant spacing was found 5.23 t ha-1 from 30 cm×17 cm.
为了确定移秧机株距对粮食产量的影响，本研究在孟加拉国水稻研究所Rangpur地区站进行了实验室试验，并在Lalmonirhat Fulgachi的农民田间进行了Aman季节的BRRI dhan52田间试验。采用3个水平株距(30 cm×13 cm、30 cm×15 cm、30 cm×17 cm)、苗木密度设置(Middle、Middle+1和Middle+2)和RCBD，共9个样地。田间试验采用3株行距和中+2苗密度设置。该移动式自行式插秧机的田间容量为0.134 ha h -1，田间效率为68%，耗油量为3.71 L ha-1。机械移栽和人工移栽所需劳动力分别为6.75人和223人小时/公顷。机械移栽的成本为每公顷3291塔卡，而人工移栽的成本为每公顷13000塔卡。如果这台机器的年使用量减少，每公顷的运营成本就会增加。从机械和人工操作成本的盈亏平衡分析中发现，为了使每公顷的操作成本降到最低，插秧机每年应至少使用11公顷。当株距为17 cm、15 cm和13 cm时，每公顷需要量分别为218个、270个和277个。间距为17 cm和15 cm的育苗盘数比间距为13 cm的育苗盘数节约21%和2.53%。在30 cm×17 cm间距下，最小苗数需要量最大。托盘的保存。不同行距(30 cm×13 cm、30 cm ×15 cm、30 cm ×17 cm)和人工移栽的籽粒产量分别为4.43、4.97、5.23、4.13 t hm -1。结果表明，在30 cm×17 cm处，籽粒产量最高，株距为5.23 t ha-1。
