Fall armyworm (Spodoptera frugiperda) has spread rapidly and posed numerous threats to the food security and livelihood of millions of smallholder farmers in Ghana. This study quantifies the damages of fall armyworm infestation in maize production and identifies the various methods used in controlling fall armyworm infestation. Almost all farmers 94% experienced fall armyworm infestation on their farms. They cited key common visual damages as yellowish leaves, stunted growth, poor yield quality, holes in leaves, and egg masses on leaves. Farmer’s loss an average of GH¢2616.07 to fall armyworm infestation. Pesticide application is the frequent control measure mostly used by farmers. Farmers do not mostly use biological methods for the control of the fall armyworm. The use of pesticide as a control method is however not effective as about GH¢ 3 000 per 1 acre is lost with the use of insecticides. It is recommended that the use of other control measures like the contemporary measures involving the use of birds and chickens as predators of eggs and worms of fall armyworm should be encouraged.JEL code:  Q16
秋粘虫(Spodoptera frugiperda)迅速蔓延,对加纳数百万小农的粮食安全和生计构成诸多威胁。本研究量化了秋粘虫对玉米生产的危害,并确定了防治秋粘虫的各种方法。几乎所有农民(94%)的农场都遭受过秋粘虫侵扰。他们列举了主要的常见视觉损害,如叶子变黄、生长发育迟缓、产量质量差、叶子上有洞和叶子上有卵团。农民因秋粘虫虫害的平均损失为2616.07美元。农药是农民常用的常用防治措施。农民大多不使用生物方法来控制秋粘虫。然而,使用杀虫剂作为一种控制方法并不有效,因为使用杀虫剂每英亩损失约3 000戈尔曼。建议应鼓励采用其他控制措施,如利用鸟和鸡作为秋粘虫卵和虫的捕食者的当代措施。JEL代码:Q16

Packaging does not only protect a product but also provides directions for using the product, as well as relevant information about its content and nutritional value. This study was undertaken to assess Granulated Cassava (Gari) sellers’ perception, profitability and determinants of packaging in Ashanti Region. The study area was purposively selected because of the active participation and contribution of marketing activities. A structured questionnaire was administered in the form of interview to obtain primary data from the respondents. Data was generated using binary and multinomial logit regression model and Garret ranking technique. The results showed that there is 0.11% difference in the gross margin of both ventures which is also statistically significant at 1%. Years of education, legal requirement, and durability of the packaging material and cost of packaging material were the significant factors that influence sellers’ choice of packaging. Lack of technical know-how, cost of capital equipment and lack of knowledge on packaging equipment and/or material were the most limiting constraints affecting Gari packaging. The study recommends that investors should invest in the Gari packaging business since it has a relatively higher rate of returns as compared to the unpackaged one.
包装不仅保护产品,而且提供产品的使用说明,以及有关其含量和营养价值的相关信息。本研究是进行评估粒状木薯(Gari)卖家的看法,盈利能力和包装在阿散蒂地区的决定因素。由于市场营销活动的积极参与和贡献,有目的地选择了研究区域。以访谈的形式进行结构化问卷调查,以获取受访者的原始数据。数据采用二元和多项回归模型和加勒特排序技术生成。结果表明,两家企业的毛利率差异为0.11%,在1%的水平上也具有统计学意义。受教育年限、法律要求、包装材料的耐用性和包装材料的成本是影响卖方选择包装的重要因素。缺乏技术知识、资本设备成本和缺乏包装设备和/或材料方面的知识是影响加里包装的最有限的制约因素。该研究建议投资者应该投资于Gari包装业务,因为与未包装的业务相比,它的回报率相对较高。

Comparison study of the agricultural subsidy policy applied by Ecuador and Hungary in the last 10 years 厄瓜多尔与匈牙利近10年农业补贴政策比较研究
Pub Date : 2022-06-30 DOI: 10.19041/apstract/2022/1/9

Agricultural subsidies have long been a consistent concern of government policies; they influence the use of resources for pursuing different goals in this sector. In this research, we are making a comparison study of the agricultural subsidy policies of Ecuador and Hungary in the last ten years by a comparative analysis applied for empirical generalization to explain and get a better understanding of the subsidies used in the two countries. The results show an enormous advantage for Hungary compared to Ecuador regarding the agricultural subsidies. Since they are part of the Common Agricultural Policy of the European Union, Hungary's subsidies are institutionalized and planned in the long term within a series of programs financed by the EU and national funds. While in Ecuador, agricultural policies exist as a general framework, and the governing body manages the subsidies through programs and projects that do not remain over time and depend on the current political situation in the country. In the same way, the data collected reflects that although the share of the agricultural sector in Ecuador's GDP is higher than in Hungary, the subsidy amounts for this sector are 36% lower than in Hungary. JEL CODE: Q13
农业补贴长期以来一直是政府政策关注的焦点;它们影响资源的使用,以实现本部门的不同目标。在本研究中,我们对厄瓜多尔和匈牙利近十年的农业补贴政策进行了比较研究,采用比较分析的方法进行实证推广,以更好地解释和理解两国的补贴政策。结果显示匈牙利在农业补贴方面比厄瓜多尔有巨大的优势。由于它们是欧盟共同农业政策的一部分,匈牙利的补贴是制度化的,并在欧盟和国家基金资助的一系列方案中长期规划。而在厄瓜多尔,农业政策作为一个总体框架存在,管理机构通过计划和项目管理补贴,这些计划和项目不会随着时间的推移而持续,并取决于该国当前的政治局势。同样,收集的数据表明,尽管厄瓜多尔农业部门在国内生产总值中所占的份额高于匈牙利,但该部门的补贴金额比匈牙利低36%。Jel代码:q13

Pub Date : 2022-06-30 DOI: 10.19041/apstract/2022/1/2
B. Ahrendsen
The purpose of the paper is to demonstrate the potential of experiential learning in fulfilling the role of higher education institutions in teaching and promoting an MBA education. The educational achievements of the Green Week of the MBA in Agribusiness and Commerce (AgriMBA) are highlighted and challenges and areas in need of improvement are discussed.Curriculum serves as the foundation of teaching students. While progress has been made in MBA curriculum, including economics, informatics, finance, marketing, and management, integrating these knowledge areas into experiential learning should be a key component of an MBA education. The AgriMBA provides such an integration of knowledge areas within an experiential learning environment of the Green Week. The Green Week has included 343 students representing 21 countries, six continents, and 11 universities, involved 34 case studies, and hosted by six universities during the 17 years it has been held.Although most MBA programs include case studies in their curriculum, the Green Week is unique in providing “live”, real-time case studies, where students representing multiple universities and countries come together to present their recommendations to business executives. This intensive, experiential learning opportunity exhibits how students from different cultural backgrounds are able to quickly form functional teams, apply curriculum knowledge areas, and effectively achieve this ambitious goal.JEL CODE: A23
本文的目的是证明体验式学习在履行高等教育机构在教学和促进MBA教育中的作用方面的潜力。重点介绍了农业与商业工商管理硕士(AgriMBA)绿色周的教育成就,并讨论了面临的挑战和需要改进的领域。课程是教育学生的基础。虽然MBA课程已经取得了进步,包括经济学、信息学、金融学、市场营销和管理学,但将这些知识领域整合到体验式学习中应该是MBA教育的关键组成部分。AgriMBA在绿色周的体验式学习环境中提供了这样一个知识领域的整合。绿色周共有来自21个国家、6大洲、11所大学的343名学生参加,涉及34个案例研究,17年来由6所大学主办。尽管大多数MBA课程都包括案例研究,但绿色周的独特之处在于提供了“现场”、实时的案例研究,代表多所大学和国家的学生聚集在一起,向企业高管提出他们的建议。这种密集的体验式学习机会展示了来自不同文化背景的学生如何能够快速组建功能团队,应用课程知识领域,并有效地实现这一雄心勃勃的目标。Jel代码:a23

This study investigated the intensity and profitability of smallholder cassava farmers’ involvement in cassava value addition in Afijio Local Government Area of Oyo State, Nigeria. Data were collected from 150 cassava farming households through the use of a well-structured questionnaire and employing a simple random sampling procedure. The data collected included information on the socioeconomic characteristics of the respondents, intensity of value addition among the respondents, factors influencing their decisions to add value as well as the extent of value addition, profitability of cassava value addition and the factors that determined the profitability level of the enterprises. The data were analyzed using the descriptive statistics for profiling the socioeconomic characteristics of the respondents, gross margin was used to measure profitability, and ordinary least squares regression model was used to determine the factors influencing the decisions of smallholder cassava farmers to add value to cassava as well as the extent of value addition among them. The results revealed that majority of the respondents were females (52.7%) with average age between 31-40 years of age while the average household size (52.7%) is between 6-10 members. Regression analysis of the determinants of the intensity of value addition revealed that the decisions to add value to cassava as well as the extent to which value was added were influenced positively by educational attainment, household size, and years of experience in cassava value addition. Results of the gross margin analysis revealed a positive return on variable costs thus indicating that the cassava value adding enterprise is a profitable one. These findings presented the need for all the stakeholders concerned to focus their attentions on proffering solutions to the challenges faced by cassava processors within the minimum time possible.JEL code: L11, M11, M21, Q13, R32
本研究调查了尼日利亚奥约州Afijio地方政府地区小农木薯参与木薯增值的强度和盈利能力。通过使用结构良好的问卷和采用简单的随机抽样程序,从150个木薯农户中收集数据。收集的数据包括受访者的社会经济特征、受访者的增值强度、影响其增值决策的因素以及增值程度、木薯增值的盈利能力以及决定企业盈利水平的因素。采用描述性统计分析数据,分析受访者的社会经济特征;采用毛利率衡量盈利能力;采用普通最小二乘回归模型确定影响小农木薯增值决策的因素及其增值程度。调查结果显示,大多数受访者为女性(52.7%),平均年龄在31-40岁之间,平均家庭人数在6-10人之间(52.7%)。对增值强度决定因素的回归分析显示,对木薯增值的决定以及增值的程度受到受教育程度、家庭规模和木薯增值经验年数的积极影响。毛利率分析的结果显示可变成本的回报为正,表明木薯增值企业是一个盈利的企业。这些发现表明,所有有关利益攸关方都需要集中精力,在尽可能短的时间内为木薯加工商面临的挑战提供解决方案。JEL代码:L11, M11, M21, Q13, R32

Food labels contain much information that helps consumers to make decisions based on the details which are of much importance to them. The study assessed awareness, perception and factors that influence consumers’ interest in labelling of sobolo in the Kumasi Metropolis of Ashanti region, Ghana. Systematic random sampling was used to select 300 respondents from five randomly selected sub-metros and data were collected using a semi structured questionnaire. Descriptive statistics such as frequencies, tables and percentages were used to summarize the socio-economic characteristics of respondents. Perception index was used to assess the perception statements on the product labelling and the Logistic Regression Model was used to analyze the factors that significantly influence consumers’ interest in labelling of sobolo. Results of the study showed that majority (97.3%) of respondents were not aware of labelled sobolo but 67% was interested, though with low awareness. The estimated perception index (2.8) showed that consumers had positive perception about labelling of sobolo. Among the socio-economic characteristics; age, education, household income and household size and respondents’ perception on health and safety aspects of sobolo were found to significantly influence interest in labelling of sobolo. In conclusion, the study found that, consumers would prefer different information on labels and thus their interests are significantly influenced by different factors.

食品标签包含很多信息,这些信息可以帮助消费者根据对他们非常重要的细节做出决定。该研究评估了加纳阿散蒂地区库马西都会区影响消费者对索博罗标签兴趣的意识、观念和因素。采用系统随机抽样的方法,从随机选取的5个城市中抽取300名调查对象,采用半结构化问卷收集数据。使用频率、表格和百分比等描述性统计来总结受访者的社会经济特征。使用感知指数评估消费者对产品标签的感知陈述,并使用Logistic回归模型分析影响消费者对索博罗标签兴趣的显著因素。研究结果显示,大多数(97.3%)的受访者不知道标签sobolo,但67%的人感兴趣,尽管意识较低。估计的感知指数(2.8)表明消费者对索博罗标签有积极的看法。在社会经济特征中;年龄、教育程度、家庭收入和家庭规模以及答复者对烟的健康和安全方面的看法对烟标签的兴趣有重大影响。综上所述,本研究发现,消费者对标签信息的偏好不同,因此消费者的兴趣受到不同因素的显著影响。建议应努力提高对食品标签的认识、教育和兴趣,以提高食品工业的生产、消费和可持续性。

The study assessed awareness, perception and factors that influence consumers’ interest in labelling of sobolo in the Kumasi Metropolis of Ashanti region, Ghana. Systematic random sampling was used to select 300 respondents from five randomly selected sub-metros and data were collected using a semi structured questionnaire. Descriptive statistics such as frequencies, tables and percentages were used to summarize the socio-economic characteristics of respondents. Perception index was used to assess the perception statements on the product labelling and the Logistic Regression Model was used to analyze the factors that significantly influence consumers’ interest in labelling of sobolo. Results of the study showed that majority (97.3%) of respondents were not aware of labelled sobolo but 67% was interested, though with low awareness. The estimated perception index (2.8) showed that consumers had positive perception about labelling of sobolo. Among the socio-economic characteristics; age, education, household income and household size and respondents’ perception on health and safety aspects of sobolo were found to significantly influence interest in labelling of sobolo. In conclusion, the study found that, consumers would prefer different information on labels and thus their interests are significantly influenced by different factors. It is recommended that efforts should be made to promote the awareness, education and interest in labelling of food products to enhance production, consumption and sustainability of the food industry.","PeriodicalId":32569,"journal":{"name":"Apstract Applied Studies in Agribusiness and Commerce","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91001111","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}

Climate adaptation is a major challenge. Chasing the sufficient amount of hay is getting in higher priority. Distant mass hay producers give favourable offers despite long distances. Quality is also gaining position and indicators like RFQ (Relative Forage Quality) is highlighting the marketing language. Hay market as we knew no longer exists in Hungary. Most farmers produce their own hay and do not spend extra cents to buy bales. Climate change however, force them to adapt and store more bales for the future. Horse owners and dairy farmers are the main driver to convince hay producers to provide high quality forage. We gathered Hungarian regional hay-price information and evaluated the trends in this sector. The demand-driven hay-price is in contradiction with premium quality timothy grass hay.JEL code: Q11
适应气候变化是一项重大挑战。追逐足够数量的干草变得越来越重要。尽管距离遥远,遥远的干草生产商仍提供有利的报价。质量也占据了越来越重要的地位,RFQ(相对饲料质量)等指标正在成为市场营销语言的重点。我们所知道的干草市场在匈牙利已经不存在了。大多数农民自己生产干草,不花额外的钱购买干草包。然而,气候变化迫使他们适应并为未来储存更多的棉花。马主和奶农是说服干草生产商提供高质量饲料的主要驱动力。我们收集了匈牙利地区干草价格信息,并评估了该部门的趋势。需求驱动的干草价格与优质的蒂莫西草干草相矛盾。JEL代码:Q11

Nigeria is experiencing a gradual shift from subsistence to commercialized agriculture, thereby increasing involvement and activities at different nodes of agribusiness. Participation of farmers in markets is an important determinant of well-being and development, and one of the pathways towards economic growth. This study analysed household crop commercialization in Nigeria. The secondary data used were the General Household Survey (GHS, 2018) Wave 4. Data were analysed using descriptive statistics, household crop commercialization index (HCCI) and ordered probit regression model. Mean age of Nigerian farmers was 50.04 years (±15.22), majority (85.68%) were male, married (82.51%), and 72.14% had formal education. Farming is viable in all the geopolitical zones and majority (87.64%) of the farmers were from the rural sector, holding a mean total plot size of 12.61(±15.63) hectares, and planted 3 crops on the average. The most produced crop categories are cereals (46.75%), tubers (20.70%) and legumes (19.00%); legumes and cereals are highest in the North, and tubers in the South. Subsistence households were 32.81% (HCCI=0), only 1.71% of the households were fully commercial (HCCI=100), while semi-subsistence households (0≤HCCI≤100) constitute 65.48%. Years of education (p<0.05) and crop production in North East and North West zones (p<0.01) constrain commercialization, while at p<0.01, crop production in the rural sector and the South zones, and increased land holding are the drivers of household crop commercialization in Nigeria. Nigerian farming households are mainly semi-subsistence and are diversified in crop production. Nigeria relies more on market participation of the semi-subsistence households, through their marketable surplus, to feed her teeming population and for exports. Further attention on rural infrastructure development in all geopolitical zones and awareness creation on producing market oriented products will increase agribusiness activities. This will generate green decent jobs that will take unemployed youths off the streets of urban centres. This is in tune with the economy diversification bid and the new Nigeria Economic Sustainability Plan of the Federal Government of Nigeria. JEL CODE – Q13
尼日利亚正在经历从自给农业向商业化农业的逐步转变,从而增加了农业综合企业不同节点的参与和活动。农民参与市场是福祉和发展的重要决定因素,也是实现经济增长的途径之一。本研究分析了尼日利亚的家庭作物商业化情况。使用的辅助数据是综合住户调查(GHS, 2018)第四波。采用描述性统计、农户作物商品化指数(HCCI)和有序probit回归模型对数据进行分析。尼日利亚农民平均年龄为50.04岁(±15.22岁),男性占85.68%,已婚占82.51%,受过正规教育的占72.14%。农业在所有地缘政治区域都是可行的,大多数(87.64%)农民来自农村,平均总地块面积为12.61(±15.63)公顷,平均种植3种作物。产量最大的作物类别是谷物(46.75%)、块茎(20.70%)和豆类(19.00%);豆科植物和谷类植物在北方最多,块茎植物在南方最多。低保户占32.81% (HCCI=0),完全商业户仅占1.71% (HCCI=100),半低保户(0≤HCCI≤100)占65.48%。东北和西北地区的受教育年限(p<0.05)和作物产量(p<0.01)限制了商业化,而在尼日利亚,农村部门和南部地区的作物产量以及土地持有量的增加是家庭作物商业化的驱动因素(p<0.01)。尼日利亚的农户主要是半自给自足的,作物生产多样化。尼日利亚更多地依靠半自给家庭的市场参与,通过其可销售的剩余来养活其庞大的人口和出口。进一步关注所有地缘政治区域的农村基础设施发展和提高对生产面向市场产品的认识将增加农业综合企业活动。这将创造绿色体面的就业机会,让失业的年轻人离开城市中心的街道。这与尼日利亚联邦政府的经济多样化投标和新的尼日利亚经济可持续发展计划是一致的。Jel代码- q13

This paper analyses the good political and legal environments, mutually beneficial strategic policy, along with level of economic development and growth, superior geographical conditions and cultural integration degree of the important effecting factors of the energy cooperation between Kazakhstan and China. By using the main points listed above this article refers to related trade and investment theories, and it’s divided into two aspects: Kazakhstan's export of Chinese energy products with time series data 1998-2014 and China's investment in Kazakhstan's energy sector with time series data 1998-2016 to construct the vector autoregressive model (VAR).We selected relevant variables and data to construct an econometric model from the perspectives of trade and investment to make an empirical analysis on the influencing factors of energy cooperation between Kazakhstan and China. Our results show that China's demand for large-scale market and for opening to the outside world as well as Kazakhstan’s great energy potential are the most important factors their cooperation. It can be stated that in our days Kazakh legislation is suitable for promoting the Chinese energy investments, but in the long run it would be beneficial to mobilize national capital especially in RES investments and research. In the end, we found the most important reserves in competitiveness of electricity and heat (both from fossil and renewable energy sources) are power grid consolidation and waste heat utilization in the short run.JEL CODE: F14; Q43
本文分析了良好的政治法律环境、互惠互利的战略政策、经济发展和增长水平、优越的地理条件和文化融合程度是影响哈中能源合作的重要因素。本文利用上述要点,参考相关的贸易和投资理论,分为1998-2014年时间序列数据哈萨克斯坦对中国能源产品的出口和1998-2016年时间序列数据中国对哈萨克斯坦能源部门的投资两个方面,构建向量自回归模型(VAR)。选取相关变量和数据,从贸易和投资的角度构建计量经济模型,对哈中能源合作的影响因素进行实证分析。结果表明,中国对大市场和对外开放的需求以及哈萨克斯坦巨大的能源潜力是两国合作的最重要因素。可以说,目前哈萨克斯坦的立法适合促进中国的能源投资,但从长远来看,这将有利于调动国家资本,特别是在可再生能源投资和研究方面。最后,我们发现电力和热能(包括化石能源和可再生能源)竞争力中最重要的储备是电网整合和短期内的废热利用。凝胶代码:f14;Q43
