A field experiment was carried out during October, 2021 to March, 2022 with an objective to evaluate growth and yield parameters of broccoli (Brassica oleracea var. italica L.) varieties in the Horticulture Farm of Agriculture and Forestry University, Rampur, Chitwan, Nepal. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The treatments were six broccoli varieties viz. two open pollinated (Calabrese and Green Sprouting) and four hybrid varieties (Centauro, Century, Delight, Everest Green). Data were collected for biometrical, phonological, yield and yield attributing characteristics. Results revealed significance for growth and yield parameters.  Calabrese had the tallest plant (100.60 cm), the highest leaf number per plant (15.75), the longest leaf (73.90 cm), higher canopy diameter (101.75 cm) and earliness in head initiation (54.50 days) as well as head maturity (60.25 days). Highest head diameter (30.13 cm) and economic yield (22.52 mt/ha) was observed in Century. Thus, Century was found more profitable for commercial production in the environment conditions of Chitwan, Nepal.

Heavy metals contamination of water is considered as severe global issues for developing countries like Bangladesh. Because heavy metal pollution ruined aquatic ecosystem especially fish diversity which contribute important share on economy of a country. The present study designed to investigate the contamination level of lead (Pb), chromium (Cr), cadmium (Cd), copper (Cu) and zinc (Zn) in surface water of Bakkhali river estuary in Bangladesh. The decreasing order of metals concentration was Cu>Zn >Cr>Pb>Cd with the mean value of 2.6> 0.825 > 0.355 > 0.056 >0.003 mg/L, respectively. The results showed a significant seasonal variation of heavy metals concentration in water. Higher contamination occurred during post monsoon, while lower during the monsoon season. Among the all studied heavy metals Cu concentration was higher (2.6 mg/L) and lower (0.003 mg/L) concentration was Cd. Metal concentrations in water samples exceeded the safe limits of drinking water which indicated that the water from this estuarine river is not fully safe for using/drinking. The study area was not entirely polluted in terms of all metal concentrations. But level of metal concentration in polluted sites supposed risk to ecological health. The findings of present study recommended that continuous monitoring of water should be aimed to evaluate the risk which could help to maintain healthy coastal ecosystem and improve management strategy of this estuarine river.
对于孟加拉国这样的发展中国家来说,水体重金属污染是一个严重的全球性问题。因为重金属污染破坏了水生生态系统,尤其是鱼类多样性,而鱼类多样性对一个国家的经济贡献巨大。本研究旨在调查孟加拉国巴克哈里河口地表水中铅(Pb)、铬(Cr)、镉(Cd)、铜(Cu)和锌(Zn)的污染水平。金属浓度的递减顺序为铜>锌>铬>铅>镉,平均值分别为 2.6>0.825>0.355>0.056>0.003 mg/L。结果表明,水中的重金属浓度有明显的季节性变化。季风后污染程度较高,而季风季节污染程度较低。在所有研究的重金属中,铜的浓度较高(2.6 毫克/升),镉的浓度较低(0.003 毫克/升)。水样中的金属浓度超过了饮用水的安全限值,这表明这条河口的水不能完全安全饮用。就所有金属浓度而言,研究区域并非完全受到污染。但受污染地区的金属浓度水平对生态健康构成了风险。本研究结果建议,应对水体进行持续监测,以评估风险,这将有助于维持健康的沿海生态系统,并改进该河口河流的管理策略。

Poor yield, non-uniform ripening, and delay in maturity are some serious issues faced by commercial banana growers in the country. This research was conducted in a commercial banana orchard of Chitwan from December 2021 to April 2022 in order to study the effect of different doses of ethephon on growth, maturity, and quality of banana. Five different doses of ethephon (200, 400, 600, 800, 1000 ppm) were sprayed on a banana bunch at 15th days after shooting which were compared with the control (no ethephon treatment) in RCBD design.  The maturity of the bunch was significantly hastened at a higher concentration of ethephon (above 600 ppm). Fruit length and fruit weight were also observed higher at 600 ppm (10.21 cm and 62.68 g) and 800 ppm (10.67 cm and 63.26 g) ethephon spray. The bunch treated with 600 ppm ethephon had the highest TSS (10.78oB and 23.27oB at 0 and 5 days of storage, respectively) and PPR (1.65). Considering quantitative and qualitative parameters, preharvest ethephon spray @600 ppm significantly improved growth, maturity, and quality of banana fruits.

Biochar is rich in carbon and obtained by carbonization of biomass heated at 300-1000°C under limited oxygen which improves the soil properties and yield of various crops. This study aimed to determine the changes in soil properties and agronomical characteristics of okra by biochar prepared from different feedstock. The research was conducted in randomized blocks and replicated thrice, with treatments; control, wood ash (WA), rice husk biochar (RHB), bamboo biochar (BB), Ashoka leaves biochar (ALB), coconut husk biochar (CHB), and sawdust biochar (SB), applied at 18 t/ha. Biochar-incorporated soil and the biochar were analyzed for pH, electrical conductivity, nitrogen, P2O5, K2O, and organic matter, and the soil for bulk density, particle density, and porosity. Agronomical parameters like plant height, fruit size, and yield were also recorded. The biochar incorporation modified the soil's chemical properties and significantly decreased bulk and particle density. The highest reduction of 10.9% in bulk density (1.22gm/cm3), and 4.4% in particle density (2.39gm/cm3) were observed in ALB and SB incorporated soil respectively. ALB (50%) followed by BB (49%) showed a significant increase in soil porosity compared to the control (45.18%). BB (15.7cm) significantly increased the fruit size compared to the control (14.06cm) followed by ALB (15.5cm). ALB (8.16t/ha) significantly increased the yield of okra relative to control (7.82t/ha). The findings suggest the use of ALB and BB to improve soil properties and yield in the long run.
生物炭富含碳元素,是在有限的氧气条件下将生物质在 300-1000°C 的温度下加热碳化而得到的,它能改善土壤性质,提高各种作物的产量。本研究旨在确定不同原料制备的生物炭对土壤性质和秋葵农艺特性的影响。研究采用随机区块法,重复三次,处理为对照、木灰(WA)、稻壳生物炭(RHB)、竹生物炭(BB)、阿育王叶生物炭(ALB)、椰壳生物炭(CHB)和锯屑生物炭(SB),施用量为 18 吨/公顷。对加入生物炭的土壤和生物炭进行了 pH 值、电导率、氮、P2O5、K2O 和有机物分析,对土壤进行了容重、颗粒密度和孔隙度分析。此外,还记录了植株高度、果实大小和产量等农艺参数。生物炭的加入改变了土壤的化学特性,并显著降低了容重和颗粒密度。在加入 ALB 和 SB 的土壤中,容重(1.22 克/立方厘米)和颗粒密度(2.39 克/立方厘米)分别降低了 10.9% 和 4.4%。与对照组(45.18%)相比,ALB(50%)和 BB(49%)显著增加了土壤孔隙度。与对照(14.06 厘米)相比,BB(15.7 厘米)明显增加了果实大小,其次是 ALB(15.5 厘米)。与对照(7.82吨/公顷)相比,ALB(8.16吨/公顷)明显提高了秋葵的产量。研究结果表明,从长远来看,使用 ALB 和 BB 可以改善土壤性质,提高产量。

Farmers’ Perceptions of the impact of climate change on apple production in lower Mustang, Nepal 尼泊尔下穆斯坦地区农民对气候变化对苹果生产影响的看法

Undoubtedly, climate change is becoming a worldwide concern due to its great sensitivity and detrimental effects on livelihood. The government, policymakers, and other relevant stakeholders are striving to come up with novel and innovative approaches to combat the effects of climate change. Nevertheless, understanding and perceptions of the issue among local farmers are more crucial before making mitigation or adaptation plans. It’s them who are actually more exposed to these environmental works and who are on the frontlines of climate change. So, the study was conducted in 2022 at Lower Mustang to understand how farmers perceive climate change, how it has impacted apple production, and to find discrepancies between their perceptions and the actual change in climatic variability recorded by the Department of Hydrology and Meteorology (DHM). Temperature and precipitation were two climatic variables that were taken into account to investigate the significant effects they have on the rate of apple production. Altogether, 60 households from Lower Mustang were selected randomly for the study. Pre-tested interviews, focus group discussions, key informant interviews, as well as secondary data from DHM, the Ministry of Agriculture and Livestock Development (MoALD), etc. were used to collect the required information. The majority of farmers observed an increase in temperature (83.30%) and an unpredictable increase in rainfall (98%), which are consistent with the actual change in temperature and precipitation recorded between 1991 and 2021. Findings show that the average annual temperature and mean annual precipitation are increasing at a rate of 0.012°C per year and 0.4146 mm per year, respectively. This has resulted in the outbreak of significant amounts of diseases and insect pest infestations that have a direct impact on the quality and quantity of apples. The majority of farmers acknowledged that rainfall was the most significant climatic hazards that negatively impacted apple production, followed with hailstones having an impact on apples during flowering and fruiting. Farmers in the study area are limited to intercropping practices, mostly as an adaptation strategy to combat the impacts of climate change. The study concluded that farmers perceived climate change; they are aware of the term ‘Climate Change’ but haven’t taken any significant adaptation measures towards it. So, there is an immediate need for effective adaptation mechanisms, taking into account farmers' perspectives, to make Lower Mustang self-sufficient in apple production. 
毋庸置疑,由于气候变化对生计的巨大敏感性和有害影响,气候变化正成为全世界关注的问题。政府、政策制定者和其他相关利益方正在努力提出新颖、创新的方法来应对气候变化的影响。然而,在制定减缓或适应计划之前,当地农民对这一问题的理解和认识更为关键。事实上,正是他们更容易受到这些环境工程的影响,他们处于气候变化的第一线。因此,这项研究于 2022 年在下野马塘进行,目的是了解农民如何看待气候变化、气候变化对苹果生产的影响,并发现他们的看法与水文和气象局(DHM)记录的气候变异性实际变化之间的差异。气温和降水是两个气候变量,目的是调查它们对苹果生产率的显著影响。研究从下野马随机抽取了 60 户家庭。为了收集所需的信息,研究人员采用了预先测试的访谈、焦点小组讨论、关键信息提供者访谈,以及来自 DHM、农业和畜牧业发展部(MoALD)等部门的二手资料。大多数农民观察到气温升高(83.30%)和降雨量不可预测的增加(98%),这与 1991 年至 2021 年期间记录的气温和降水量的实际变化相符。研究结果表明,年平均气温和年平均降水量分别以每年 0.012°C 和 0.4146 毫米的速度增长。这导致了大量病虫害的爆发,直接影响了苹果的质量和数量。大多数果农承认,降雨是对苹果生产造成负面影响的最主要气候灾害,其次是冰雹对苹果开花结果的影响。研究地区的农民仅限于采用间作方法,主要是作为应对气候变化影响的一种适应战略。研究得出的结论是,农民感知到了气候变化;他们知道 "气候变化 "这个词,但没有采取任何重大的适应措施。因此,迫切需要建立有效的适应机制,考虑到农民的观点,使下野马苹果生产实现自给自足。

The government, policymakers, and other relevant stakeholders are striving to come up with novel and innovative approaches to combat the effects of climate change. Nevertheless, understanding and perceptions of the issue among local farmers are more crucial before making mitigation or adaptation plans. It’s them who are actually more exposed to these environmental works and who are on the frontlines of climate change. So, the study was conducted in 2022 at Lower Mustang to understand how farmers perceive climate change, how it has impacted apple production, and to find discrepancies between their perceptions and the actual change in climatic variability recorded by the Department of Hydrology and Meteorology (DHM). Temperature and precipitation were two climatic variables that were taken into account to investigate the significant effects they have on the rate of apple production. Altogether, 60 households from Lower Mustang were selected randomly for the study. Pre-tested interviews, focus group discussions, key informant interviews, as well as secondary data from DHM, the Ministry of Agriculture and Livestock Development (MoALD), etc. were used to collect the required information. The majority of farmers observed an increase in temperature (83.30%) and an unpredictable increase in rainfall (98%), which are consistent with the actual change in temperature and precipitation recorded between 1991 and 2021. Findings show that the average annual temperature and mean annual precipitation are increasing at a rate of 0.012°C per year and 0.4146 mm per year, respectively. This has resulted in the outbreak of significant amounts of diseases and insect pest infestations that have a direct impact on the quality and quantity of apples. The majority of farmers acknowledged that rainfall was the most significant climatic hazards that negatively impacted apple production, followed with hailstones having an impact on apples during flowering and fruiting. Farmers in the study area are limited to intercropping practices, mostly as an adaptation strategy to combat the impacts of climate change. The study concluded that farmers perceived climate change; they are aware of the term ‘Climate Change’ but haven’t taken any significant adaptation measures towards it. So, there is an immediate need for effective adaptation mechanisms, taking into account farmers' perspectives, to make Lower Mustang self-sufficient in apple production. ","PeriodicalId":8147,"journal":{"name":"Archives of Agriculture and Environmental Science","volume":" 521","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study conducted in Gadhawa Rural Municipality, Dang district, from November 2021 to April 2022, the impact of two sowing methods (Line sowing and broadcasting) and four varieties (Bijaya, Gautam, Aditya, and Borlaug 2020) on wheat was investigated. We aimed to identify the best sowing method and variety using a randomized complete block design with three replications. The study focused on various growth and yield parameters, including plant height, tiller number, grain per spike, effective tillers per square meter, thousand grain weight, grain yield per hectare, and biological yield per hectare. Line sowing was found to have the highest impact on biometrical as well as yield attributing characters. More height (111.51 cm), number of tillers (3.80), grain/spike (57.02), and grain yield (3.85 ton/ha) were obtained in line sowing. There was a significant difference observed among the varieties for all the traits except tiller number and biological yield. Borlaug 2020 was found to be superior for performance based on yield attributing traits which have grain/spike, effective tiller/m2, biological yield, and grain yield of 62.88, 177.15, 6.60 ton/ha, and 3.95 ton/ha respectively. From the interaction effects, variety Borlaug 2020 and line sowing method were found to be superior for cultivation. The study further demonstrates that farmers of Dang can combine Borlaug 2020 with line-sowing methods to obtain promising results.
本研究于 2021 年 11 月至 2022 年 4 月在当县 Gadhawa 乡进行,调查了两种播种方法(条播和撒播)和四个品种(Bijaya、Gautam、Aditya 和 Borlaug 2020)对小麦的影响。我们采用随机完全区组设计,三次重复,旨在确定最佳播种方法和品种。研究的重点是各种生长和产量参数,包括株高、分蘖数、每穗粒数、每平方米有效分蘖数、千粒重、每公顷谷物产量和每公顷生物产量。研究发现,行播种对生物特征和产量特征的影响最大。行播种获得了更高的株高(111.51 厘米)、分蘖数(3.80)、谷粒/穗数(57.02)和谷物产量(3.85 吨/公顷)。除分蘖数和生物产量外,各品种间的所有性状均存在显著差异。在产量性状方面,Borlaug 2020 表现更优,谷粒/穗、有效分蘖/平方米、生物产量和谷物产量分别为 62.88、177.15、6.60 吨/公顷和 3.95 吨/公顷。从交互效应来看,品种 Borlaug 2020 和行播法的种植效果更优。该研究进一步表明,党县农民可以将 Borlaug 2020 与行播法结合起来,以获得可喜的成果。

A field experiment was carried out on spring rice in the rabi season of 2022 from February 3 to July 4 with an aim to identify the most suitable spring rice cultivar in Kanchanpur, Nepal. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications and eight treatments. The treatments were eight spring rice genotypes: one released (Chaite-5), one local genotype (ChaineeAndi), and six pipeline varieties (IR17A2946, IR17A2796, IR17A2949, IR13F402, IR16A3838, and IR18A2066). A total of 24 experimental plots, each of 6m2 (3*2m), were set to the experimental design. The treatments were randomly assigned to the replications. Data were collected for various morphological characters such as plant height (cm), number of tillers (/plant), effective tillers (/m2), panicle length (cm), number of grains per panicle, sterility (%), thousand-grain weight (gm), grain yield (kg), straw yield (kg), biological yield (kg), and harvest index. Results revealed significance for all parameters except for the effective number of tillers per plant. ChaineeAndi took the least days to mature and had the highest effective tiller number per plant. Genotype IR17A2066 took the most days to flower and mature, and had greater plant height, thousand-grain weight, but low grain yield. Grains per panicle were higher in IR13F402 but lowest panicle length. Chaite-5 had the highest sterility percentage. Highest grain yield, straw yield, and harvest index was observed in genotypes IR16A3838, IR17A2946, Chaite-5, and IR17A2949. IR16A3838 performed superior than other genotypes in environmental conditions of Kanchanpur, Nepal.
在 2022 年 2 月 3 日至 7 月 4 日的春稻收获季节进行了一项田间试验,旨在确定最适合尼泊尔坎昌布尔的春稻栽培品种。试验采用随机完全区组设计(RCBD),有三次重复和八个处理。处理为八个春稻基因型:一个已发布的基因型(Chaite-5)、一个当地基因型(ChaineeAndi)和六个管道品种(IR17A2946、IR17A2796、IR17A2949、IR13F402、IR16A3838 和 IR18A2066)。试验设计共设 24 个试验小区,每个小区面积为 6 平方米(3*2 米)。处理被随机分配到重复中。收集了各种形态特征的数据,如株高(厘米)、分蘖数(/株)、有效分蘖数(/平方米)、圆锥花序长度(厘米)、每圆锥花序粒数、不育率(%)、千粒重(克)、谷物产量(千克)、秸秆产量(千克)、生物产量(千克)和收获指数。结果表明,除每株有效分蘖数外,其他参数均有显著性差异。ChaineeAndi 的成熟天数最少,单株有效分蘖数最高。基因型 IR17A2066 的开花和成熟天数最多,株高和千粒重较大,但谷物产量较低。IR13F402 的每圆锥花序粒数较高,但圆锥花序长度最低。Chaite-5的不育率最高。IR16A3838、IR17A2946、Chaite-5 和 IR17A2949 的谷粒产量、秸秆产量和收获指数最高。在尼泊尔 Kanchanpur 的环境条件下,IR16A3838 的表现优于其他基因型。

Numerous non-communicable diseases are being caused by changes in food and lifestyle choices. However, the global trend of eating more healthful food is growing as people become more aware of their personal health. Nonetheless, not much scholarly work has been done on the perplexing purchasing habits of customers, especially in developing nations like Bangladesh. Hence, the purpose of this study was to determine the preference for healthy food consumption and the factors associated with consuming healthy food. The study was conducted on 140 participants selected by a purposive sampling technique from Mymensingh city. Data were collected through both face-to-face surveys and via email with the help of an e-questionnaire from May 2022 to August 2022. A five-point Likert scale was applied to assess the consumer’s preference for healthy food products. The internal consistency of the items on the scale was examined by Cronbach’s alpha. In addition, binary logistic regression was used to identify the factors that affect consumers’ decisions to consume healthy food products. The study findings provide evidence of the highly disfavored attitudes (82.86%) toward healthy food consumption among people in the study area. The analysis also reveals that factors like gender, age, education, and monthly income have a positive impact on consumption decisions, while distance from the market, occupation, family size, and credit negatively affect consumption decisions.
许多非传染性疾病都是由食物和生活方式的改变引起的。然而,随着人们对个人健康的认识不断提高,全球范围内食用更健康食品的趋势也在不断增长。然而,对于顾客令人困惑的购买习惯,尤其是像孟加拉国这样的发展中国家的顾客的购买习惯,学术研究并不多。因此,本研究旨在确定人们对健康食品消费的偏好以及与消费健康食品相关的因素。研究采用目的性抽样技术,从迈门辛市选出 140 名参与者。在 2022 年 5 月至 2022 年 8 月期间,通过面对面调查和借助电子问卷通过电子邮件收集数据。采用李克特五点量表来评估消费者对健康食品的偏好。量表项目的内部一致性由 Cronbach's alpha 检验。此外,研究还采用二元逻辑回归法来确定影响消费者消费健康食品决策的因素。研究结果表明,研究地区的人们对健康食品消费持非常不赞成的态度(82.86%)。分析还显示,性别、年龄、教育程度和月收入等因素对消费决策有积极影响,而与市场的距离、职业、家庭规模和信贷则对消费决策有消极影响。

In this study, the effects of gamma radiation on the decontamination of fungus, physicochemi-cal properties, and molecular analysis of Aspergillus spp. of common spices for storage were evaluated. After being irradiated with gamma doses of 0, 2, 4, and 6 kGy and sealed in glass vials, the spices were stored at room temperature for 180 days. Among the tested spice samples, chili, turmeric, and black pepper powder showed the highest presence of fungal contamination compared to cumin, coriander, garlic, and ginger samples. Microscopy was used to identify a total of 48 isolates, of which 11 were Mucor, 25 were Penicillium, and 12 were Aspergillus. By polymerase chain reaction (PCR) amplification and sequencing of the internal transcribed spacer (ITS) region, a total of 12 Aspergillus genera were identified among them: 5 in black pepper and 7 in red chili. The gamma radiation also reduced the number of microbes compared to the control group. The best gamma radiation doses were found to kill the organ-isms in the studied spices. These were 6 kGy for red chili, 4 kGy for turmeric and black pepper, and 2 kGy for cumin, coriander, garlic, and ginger. Measurements of the physicochemical parameters were not significantly impacted by the 180-day exposure to gamma radiation; however, the number of fungi drastically decreased. Gamma radiation has been explored as an effective method for decontaminating spices, offering a promising solution for ensuring food safety and quality.
本研究评估了伽马辐射对贮藏中常见香料的真菌净化、物理化学性质和曲霉菌属分子分析的影响。香料经 0、2、4 和 6 kGy 的伽马射线辐照后密封在玻璃瓶中,在室温下储存 180 天。与孜然、香菜、大蒜和生姜样品相比,辣椒、姜黄和黑胡椒粉的真菌污染程度最高。通过显微镜共鉴定出 48 个分离物,其中 11 个为粘菌,25 个为青霉,12 个为曲霉。通过聚合酶链式反应(PCR)扩增和内部转录间隔区(ITS)测序,共鉴定出其中的 12 个曲霉属:黑胡椒中有 5 个,红辣椒中有 7 个。与对照组相比,伽马辐射也减少了微生物的数量。研究发现,伽马辐射剂量是杀死所研究香料中微生物的最佳剂量。红辣椒为 6 kGy,姜黄和黑胡椒为 4 kGy,小茴香、香菜、大蒜和生姜为 2 kGy。180 天的伽马射线照射对理化参数的测量没有明显影响,但真菌的数量却急剧下降。伽马辐射已被视为一种有效的香料去污方法,为确保食品安全和质量提供了一种前景广阔的解决方案。
