This study aimed to examine factors impacting on farmers’ decision to convert from conventional to organic agriculture in Phayao and Nan Provinces, Thailand. The perceptions in conversion from conventional agriculture to organic agriculture toward the intention to change behavior, attitudes, and decision-making were analyzed. The data were collected by questionnaires administered to 124 farmers. The theory of planned behavior and the impacting factors of farm practices using logit model were used for analysis. The reasons for adopting organic agriculture were separated into three categories: (1) knowledge and understanding; farmers understood healthy farming but had little organic farm management information; (2) farm size impacts the costs of production; and (3) farm economics, including costs of delivery, storage, and markets, were a barrier to organic farming. These influenced attitudes, group norms, and perceived behavior. The study found that 50% of farmers using conventional practices were unwilling to change their practices, 16.1% had not decided, but 25.8% decided to change to organic practices. Organic agriculture in the study area increased to approximately 30.65%. The study suggests that farmers’ long-term benefits were implementation of agricultural policies supporting equipment, financial resources, knowledge, green technologies, training, and extension.
本研究旨在探讨影响泰国Phayao和Nan省农民从传统农业转向有机农业决策的因素。分析了从传统农业转向有机农业对改变行为、态度和决策的意图的看法。数据通过对124名农民进行问卷调查收集。运用计划行为理论和logit模型对农业实践的影响因素进行分析。采用有机农业的原因分为三类:(1)认识和理解;农民了解健康耕作,但对有机农场管理信息知之甚少;(2)养殖场规模影响生产成本;(3)农业经济,包括运输、储存和市场成本,是有机农业的障碍。这些影响态度、群体规范和感知行为。研究发现,50%使用传统做法的农民不愿意改变他们的做法,16.1%尚未决定,但25.8%决定改为有机做法。研究区有机农业增长到约30.65%。研究表明,支持设备、财政资源、知识、绿色技术、培训和推广的农业政策的实施对农民具有长期效益。

Tractorization is crucial in the agricultural transformation of societies with either large farm size or challenged by a severe labor shortage. However, most smallholder farmers still lag in its use, making it necessary to investigate current tractor use by smallholders. This study investigated the factors that influence smallholder farmers’ decision to use tractors in the Delta and Benue States of Nigeria. Specifically, it determined the current level of mechanization (tractor use) in the farming system, estimated the contributions of tractor use among smallholder farmers, and determined the factors influencing smallholder farmers’ tractor use decisions in the study area. Multistage sampling techniques were used to collect data from 280 respondents. Descriptive statistics, a logistic model and odds ratio (OR) constituted the analytical framework. The results showed that poor tractor use still exists among smallholder farmers, with as much as 72% of farmers not using tractor in this modern era. The study revealed that the mean income of tractor users was twice as high as that of non-tractor users. The OR result revealed that educational status, household labor, farming experience, alternative occupation, and farm area under cultivation influenced the decision of the smallholder to use tractor services. It would seem that lack of utilizing the benefits of tractorization is a crucial constraint that calls attention to the need for a holistic campaign among the farming population. The practical applications of family labor are likely to remain high.
在农场规模较大或面临严重劳动力短缺挑战的社会,拖拉机化在农业转型中至关重要。然而,大多数小农在使用方面仍然落后,因此有必要调查目前小农使用拖拉机的情况。本研究调查了影响尼日利亚三角洲和贝努埃州小农决定使用拖拉机的因素。具体而言,它确定了当前农业系统的机械化水平(拖拉机使用),估计了小农使用拖拉机的贡献,确定了影响研究区域小农拖拉机使用决策的因素。采用多阶段抽样技术从280名受访者中收集数据。描述性统计、逻辑模型和比值比(OR)构成了分析框架。结果表明,小农的拖拉机使用率仍然很低,在这个现代时代,高达72%的农民没有使用拖拉机。研究表明,拖拉机使用者的平均收入是非拖拉机使用者的两倍。OR结果显示,受教育程度、家庭劳动、耕作经验、替代职业和耕作面积对小农使用拖拉机服务的决定有影响。似乎缺乏利用拖拉机的好处是一个关键的制约因素,它要求人们注意在农业人口中开展全面运动的必要性。家庭劳动的实际应用可能仍然很高。

We used a socio-institutional approach to characterize rural organizations in forest-based communities in North West Tunisia. This approach builds on the imperatives of a social system, the conservation of rural capital, and the role of social capital. The resulting model was used to characterize rural organizations based on key socio-institutional attributes. The paper used a Participatory Rural Appraisal (focus groups mainly) to conduct in-depth analysis in nine forest communities. Results reveal the following : 1) in Development Committees there is a strong belief in state intervention and moderate natural capital appropriation, weak conflict management, weak capacity to sanction, and low trust in the organization; 2) in active Agricultural Development Groups there exists a strong potential for conflict management, trust in the organization, and natural capital appropriation, but a lower level of degradation responsibility and capacity to sanction; and 3) in the Inactive Agricultural Development Groups there is the strongest perception of state intervention and overall weak performances in terms of conflict management, trust in organization, and degradation responsibility. These features indicate the organization’s attributes for sustainable local development and specifically for common forest resources management.
我们使用社会制度方法来描述突尼斯西北部森林社区的农村组织。这种方法建立在社会制度的必要性、农村资本的保护和社会资本的作用的基础上。由此产生的模型被用于基于关键的社会制度属性来描述农村组织。本文采用参与式农村评价法(焦点小组为主)对9个森林社区进行深入分析。结果表明:1)发展委员会对国家干预和适度自然资本拨款的信念较强,冲突管理能力较弱,制裁能力较弱,对组织的信任度较低;2)活跃的农业发展集团在冲突管理、组织信任和自然资本拨款方面存在较强的潜力,但退化责任和制裁能力水平较低;3)在不活跃的农业发展集团中,国家干预的感知最强,在冲突管理、组织信任和退化责任方面的整体表现较弱。这些特征表明了该组织在地方可持续发展,特别是共同森林资源管理方面的属性。

Soil moisture conservation, proper irrigation scheduling and nutrient management are crucial for sustainable cucumber production. A field experiment was set up over two years (2018 and 2019) to investigate the effects of irrigation frequency, black polyethylene mulching, and nitrogen fertilization on cucumber yield, water use efficiency (WUE) and nutrient use efficiency (NUE) at Ikole-Ekiti, Nigeria. The experiment was a 3 x 2 x 2 factorial in a randomized complete block design (RCBD) with a split-plot arrangement and the main plot as drip irrigation frequency: twice per week (I4), three times per week (I5), and four times per week (I6), while the sub-plots were nitrogen fertilization; (no fertilizer, N0 and 180 kg/ha urea, N180) and mulching (no mulch, NM and mulch, M). The highest yield (8.39 and 8.51 t/ha) with the best WUE was obtained from treatment I4MF (F, fertilization), while the lowest (5.81 and 5.79 t/ha) was obtained from I6MF for the respective years. The combination of variables significantly (P<0.05) influenced cucumber yield, WUE, and NUE, and significant correlations were obtained (r=0.87** and 0.85**) between WUE and fruit yield for the study years. The treatment I4MF therefore, could successfully be adopted to reduce water and fertilizer application for improved cucumber yield in the field.
土壤水分保持、合理的灌溉调度和养分管理是黄瓜可持续生产的关键。在尼日利亚Ikole-Ekiti进行了为期2年(2018年和2019年)的田间试验,研究了灌溉频率、黑聚乙烯覆盖和施氮对黄瓜产量、水分利用效率(WUE)和养分利用效率(NUE)的影响。试验采用3 × 2 × 2因子随机完全区设计(RCBD),分样布置,主样为滴灌频率:每周2次(I4)、每周3次(I5)、每周4次(I6),次样为氮肥施肥;不同年份,I4MF (F,施肥)处理产量最高(8.39和8.51 t/ha),水分利用效率最佳,I6MF处理产量最低(5.81和5.79 t/ha)。各变量组合显著(P<0.05)影响了黄瓜产量、水分利用效率和氮肥利用效率,各年份水分利用效率与果实产量呈显著相关(r=0.87**和0.85**)。因此,可以成功地采用I4MF处理在田间减少水肥用量,提高黄瓜产量。

The present study was carried out in order to evaluate the effects of feed supplementation with spiruline powder on the oxidative stress markers, biochemical characteristics, and hematological parameters in rabbit doe. Twenty-one nulliparous and sexually mature does (7–8 months old) were distributed into three groups of seven does each, comparable in terms of body weight. After a week of feeding with experimental feed, does of each group were mated. During the trial, does of group 1 (control group) were fed ad libitum with a feed free from spiruline (control feed), while those of groups 2 and 3 received the control feed supplemented with spiruline powder at 0.6 and 1.2%, respectively. Immediately after parturition, blood was collected for analyses of hematological, biochemical, and oxidative stress parameters. Studied parameters included serum concentrations of total proteins, cholesterol, aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), creatinine, and urea; malondialdehyde, reduced glutathione, catalase, and superoxide dismutase; and hematological parameters. The total protein concentration, number of white and red blood cells, platelets, hemoglobin, hematocrit, and mean corpuscular volume were significantly (P<0.05) higher in does treated compared to control. Oxidative stress parameters were comparable (P>0.05) among treatments. Hence, these results show that feed supplementation with spirulina powder can improve rabbit doe health, notably at 1.2%, since optimal results were obtained at this percentage.
本试验旨在探讨饲料中添加螺旋藻粉对家兔氧化应激指标、生化指标和血液学指标的影响。将21只7-8月龄的未生育和性成熟的公羊分为3组,每组7只,体重相近。饲喂试验饲料1周后,对各组家兔进行交配。试验期间,1组(对照组)饲喂不含螺旋藻粉的饲料(对照饲料),2组和3组饲喂在对照饲料中分别添加0.6和1.2%螺旋藻粉的饲料。分娩后立即采血,分析血液学、生化和氧化应激参数。研究参数包括血清总蛋白、胆固醇、天冬氨酸转氨酶(ASAT)、丙氨酸转氨酶(ALAT)、肌酐和尿素浓度;丙二醛、还原性谷胱甘肽、过氧化氢酶和超氧化物歧化酶;还有血液参数。两组患者总蛋白浓度、白细胞、红细胞数量、血小板、血红蛋白、红细胞压积、平均红细胞体积差异均有统计学意义(P0.05)。由此可见,饲粮中添加螺旋藻粉可改善家兔健康,以添加1.2%的螺旋藻粉效果最佳。

Rice is an important crop and a staple food in Malaysia. Herbicides are used extensively to control weeds, which represent a major constraint to yield production. Although the introduction of Imidazolinone-resistant Rice with its management system (IRPS) has greatly improved both yields and weed control, the system is designed to be used for only a short term before transitioning to local varieties. Thus, a survey was conducted among 115 farmers to obtain information on their general knowledge on weed control and IRPS. The results showed that the majority of the farmers use herbicides to control all types of weed presented, with a small minority still using manual control. The majority of farmers using IRPS were applying the herbicide imidazolinone when soil condition were right, and only once per season, which is the recommendation. Most of the farmers still utilized imidazolinone to control weedy rice but would not use it on other weeds. However, many of the farmers perceived imidazolinone as becoming more ineffective and expensive and were willing to change to other herbicides if there was a viable alternative. Although herbicide is the main method employed in controlling weeds when using IRPS, farmers still regard imidazolinone as an ineffective herbicide. The reason IRPS is still in use is due to the high yields provided. This study shows a better understanding of knowledge on weeds and IRPS among farmers. Nonetheless, the IRPS will become a redundant system due to the ineffectiveness of imidazolinone and a new system should be introduced to replace it.
大米是马来西亚重要的农作物和主食。除草剂被广泛用于控制杂草,杂草是制约产量的主要因素。虽然引入抗咪唑啉酮水稻及其管理系统(IRPS)大大提高了产量和杂草控制,但该系统仅用于短期,然后再过渡到地方品种。因此,对115名农民进行了调查,以了解他们对杂草控制和IRPS的一般知识。结果表明,大多数农民使用除草剂来控制所有类型的杂草,少数农民仍然使用人工控制。大多数使用IRPS的农民在土壤条件合适的情况下使用除草剂咪唑啉酮,并且每季只使用一次,这是推荐的。大多数农民仍然使用咪唑啉酮来控制杂草水稻,但不会使用它来控制其他杂草。然而,许多农民认为咪唑啉酮变得更加无效和昂贵,如果有可行的替代品,他们愿意改用其他除草剂。虽然使用IRPS时除草剂是控制杂草的主要方法,但农民仍然认为咪唑啉酮是一种无效的除草剂。IRPS仍在使用的原因是由于提供了高产量。这项研究表明,农民对杂草和IRPS的知识有了更好的了解。然而,由于咪唑啉酮的无效,IRPS将成为多余的系统,因此应该引入新的系统来取代它。

The reason IRPS is still in use is due to the high yields provided. This study shows a better understanding of knowledge on weeds and IRPS among farmers. Nonetheless, the IRPS will become a redundant system due to the ineffectiveness of imidazolinone and a new system should be introduced to replace it.","PeriodicalId":36876,"journal":{"name":"Asian Journal of Agriculture and Rural Development","volume":"T163 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82676394","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}

Dates represent an important export crop for Saudi Arabia that attracts foreign exchange. There is an opportunity for Saudi Arabia to extend its date exports to the international market due to production exceeding consumption and comparative advantage in date production. This paper explores the future export market for Saudi dates by analyzing the factors that affect Saudi date exports and highlighting this crop’s comparative advantage. Also, the paper uses autoregressive and distributed lag methodology with data from 1980 to 2017 to predict the future for exported dates between 2020 and 2025. The relationship between the export of dates and other exogenous variables shows there are significant effects from domestic production, domestic consumption of dates, and the price of exported dates in both the long and short term. In contrast, the comparative advantage of Saudi dates shows a significant effect only in the short term, because there has been no active program to promote Saudi dates in global markets. The explanatory variables predict that 2019 Saudi date exports will increase by 3.8-fold in 2025, with the total export amount over 700 thousand tons. Thus, there is an opportunity to develop more programs that target the international market in support of date farms and exporters, and to support market research directed at satisfying the international market.
枣是沙特阿拉伯吸引外汇的重要出口作物。沙特阿拉伯有机会将其枣出口扩大到国际市场,因为它的产量大于消费量,而且在枣生产方面具有比较优势。本文通过分析影响沙特枣出口的因素,并强调该作物的比较优势,探讨了沙特枣的未来出口市场。此外,本文使用自回归和分布滞后方法,利用1980年至2017年的数据预测2020年至2025年之间出口日期的未来。枣出口与其他外生变量的关系表明,在长期和短期内,枣的国内生产、国内消费和出口枣的价格都有显著的影响。相比之下,沙特枣的比较优势只在短期内显示出显著的效果,因为没有积极的计划在全球市场上推广沙特枣。解释变量预测,2019年沙特枣出口将比2025年增长3.8倍,出口总量将超过70万吨。因此,有机会制定更多针对国际市场的计划,以支持枣农场和出口商,并支持旨在满足国际市场的市场研究。

The Impact of Financial Factors on the After-Sales Service of Agricultural Machinery: A Case Study of Chinese Agricultural Machinery in South Africa 财务因素对农机售后服务的影响——以中国农机在南非市场为例
Q3 Social Sciences Pub Date : 2021-02-04 DOI: 10.18488/journal.ajard.2021.111.71.78

Compared to other countries, the level of agricultural mechanization in Africa and South Africa is relatively low. Among the factors that influence agricultural mechanization, after-sales service of agricultural machinery is among the most significant. On the other hand, financial resources primarily impact on improvement and enhancement of after-sales service of farm equipment. In this paper, a questionnaire was employed as the method of quantitative data collection to assist in the analysis of data from 739 respondents in the Chinese context. Due to the Covid-19 pandemic in 2020 (Mmbengwa & Qin, 2020), no questionnaires were collected from South Africa for the purposes of this paper. A standard multiple regression analysis (MRA) was utilized to analyze the data collected from the structured questionnaires. Evidence from this study suggests that combining these financial resource factors has a major effect (F2 = 0.802) on the after-sales service of farm equipment. The high scores obtained for economic factors and analyzed in this study mean that, to a large extent, these have a major impact on China’s after-sales service for agricultural machinery in South Africa.
与其他国家相比,非洲和南非的农业机械化水平相对较低。在影响农业机械化的因素中,农业机械的售后服务是最重要的。另一方面,财政资源主要影响农用设备售后服务的改进和加强。本文采用问卷调查作为定量数据收集的方法,对中国语境下739名受访者的数据进行分析。由于2020年的Covid-19大流行(Mmbengwa & Qin, 2020),本文没有从南非收集问卷。采用标准多元回归分析(MRA)对结构化问卷收集的数据进行分析。本研究的证据表明,综合这些财务资源因素对农用设备的售后服务有重大影响(F2 = 0.802)。本研究分析的经济因素得分较高,说明这些因素在很大程度上对中国在南非的农机售后服务产生了重大影响。

This research sought to explore the performance of agricultural export products on economic growth in Nigeria from 1960 to 2016. Secondary data from the National Bureau of Statistics, the Central Bank of Nigeria’s Annual Statistical Bulleting, the World Bank, and World Development Indicators were used. The Generalized Method of Moments (GMM) model was explored in this study. The findings of the study show that food and live animals, beverages, and tobacco were found to be negative but significant to agricultural exports, while agricultural exports (total) and crude materials, inedible except fats, were found to be negative and insignificant to economic growth. Animal and vegetable oils and fats were found to be positive but insignificant to economic growth. Based on the following findings, it is recommended that policies aimed at increasing the productivity and quality of agricultural products, especially those from crops, should be implemented. There is also a need to devote more resources to the production of non-export goods to increase exports. Above all, more credit should be extended to the agricultural sector with a low or zero interest rate, which may lead to a higher rate of economic growth in Nigeria.
本研究旨在探讨1960年至2016年尼日利亚农业出口产品对经济增长的影响。二手数据来自国家统计局、尼日利亚中央银行年度统计公报、世界银行和世界发展指标。本文对广义矩量法(GMM)模型进行了探讨。结果显示,食品和活畜、饮料、烟草对农产品出口的影响为负,但对经济增长的影响显著;而农产品出口(总量)和除脂肪以外不能食用的原材料对经济增长的影响为负,但对经济增长的影响不显著。研究发现,动植物油和脂肪对经济增长有积极作用,但作用不大。根据下列调查结果,建议应执行旨在提高农产品,特别是农作物的生产力和质量的政策。还需要将更多的资源用于生产非出口商品,以增加出口。最重要的是,应该以低利率或零利率向农业部门提供更多信贷,这可能导致尼日利亚的经济增长率更高。
