Wheat (Triticum aestivum) is third most important crop in Nepal after rice and maize. The area of cultivation of wheat is increasing compare to last decade but its productivity could not be increased significantly due to many biotic and abiotic factors. Among them, rust disease is major biotic constraint. Leaf rust (Puccinia triticina) is an economically important disease which occurs on major wheat growing areas of plain and hill of the country. The leaf rust disease monitoring and samples collection were done from 32 districts across the wheat growing area. Rust infected leaves were folded such that rust pustules preserved inside without destroying spores. Excess leaf moisture was removed by keeping them in room temperature with shade drying. Proper dried samples were kept in paper envelop and diagnosed pathotypes at Indian Institute of Wheat and Barley Research (IIWBR), Indian Council of Agricultural Research (ICAR), Regional Station, Flowerdale, Shimla, India. urediospores were revived on 2% water agar and multiplied in susceptible host Agra Local. The fresh urediospores of each sample was collected from susceptible host and inoculated on 5-7 days old seedlings of the standard differential sets. The pathotypes of pathogen was diagnosed on the base on disease infection type showed in the differential sets. Pathotypes 57R39 121R63-1, 21R55, 109R31-1, 121R60-1, 93R15 and 93R39 were commonly observed in both plain and hills. Similarly, the pathotypes 125R23-1, 109R63 and 21R63 were recorded in lower belt whereas, pathotypes 5R13, 49R39, 125R28, 21R31 and 93R47 were found only at hilly regions. The pathotypes 21R55, 121R63-1, 121R63-1and 5R37 were recorded in successive years in most of the wheat growing area. Twenty one different pathotypes of P. triticina occur in different parts of the country. The evolving of different pathotypes diversity of pathogens may be caused by selection pressure due to same genetic materials of wheat genotypes grown in the country and conducive environment. Hence, monitoring rust pathotypes is a one of the necessary step for successful planning to manage the rust disease by developing resistant wheat genotypes.
小麦(Triticum aestivum)是尼泊尔第三重要的作物,仅次于水稻和玉米。小麦的种植面积与近十年来相比有所增加,但由于多种生物和非生物因素的影响,其产量未能显著提高。其中,锈病是主要的生物制约因素。小麦叶锈病是我国主要平原和丘陵小麦产区的一种重要的经济病害。对小麦种植区32个区进行了叶锈病监测和样品采集。被锈病感染的叶子被折叠起来,这样锈病脓疱就被保存在里面,而不会破坏孢子。通过在室温下荫凉干燥来去除多余的叶片水分。在印度西姆拉Flowerdale地区站的印度小麦和大麦研究所(IIWBR)、印度农业研究委员会(ICAR)中,将适当干燥的样品保存在纸信封中并诊断出病原。在2%水琼脂上使孢子复活,并在易感宿主Agra Local中繁殖。从感病寄主上采集每个样品的新鲜芽孢,接种在5-7天龄的标准分化苗上。根据病原菌的感染类型,对病原菌进行病原诊断。病理型57R39、121R63-1、21R55、109R31-1、121R60-1、93R15和93R39在平原和丘陵均常见。125R23-1、109R63和21R63型主要分布在低洼地带,而5R13、49R39、125R28、21R31和93R47型主要分布在丘陵地带。病型21R55、121R63-1、121R63-1和5R37在大部分小麦产区连续出现。21种不同的小麦黑穗病型分布在全国不同地区。不同病原菌的进化多样性可能是由于国内小麦基因型遗传物质相同以及有利的环境所造成的选择压力所致。因此,监测小麦锈病的致病型是通过开发小麦抗病基因型来成功规划控制锈病的必要步骤之一。

: Sweet potato ( Ipomoea batatas (L) Lam) is one of the most important root crops. It is used as food and economically important crop in Ethiopia. However, its production and productivity is very low due to several factors: lack of information on the type and appropriate rate of fertilizers supplying major plant nutrients, which have been recognized to be deficient in Ethiopian soil and shortage of planting materials supplying system, Hence, a field experiment was conducted at Bako Agricultural Research Center in 2019/2020
甘薯(Ipomoea batatas (L) Lam)是最重要的块根作物之一。在埃塞俄比亚,它被用作食物和重要的经济作物。然而,由于以下几个因素,其产量和生产力非常低:缺乏提供主要植物养分的肥料类型和适当比例的信息,这已被认为是埃塞俄比亚土壤中缺乏的,以及缺乏种植材料供应系统,因此,2019/2020年在Bako农业研究中心进行了现场试验

: This paper assessed the profitability of smoked fish marketing in Ilaje Local Government Area of Ondo State. A multi-stage random sampling procedure was used to select one hundred and twenty (120) respondents using a well-structured questionnaire. Descriptive statistics, gross margin analysis, benefit-cost ratio and production function using an ordinary least square method were employed to analyse the field survey data. The results showed that on average, majority of the marketers were around 40 years of age. Many (90.0%) of the traders were female household heads with 14 years of marketing experience. The result revealed that 80% of the respondents were educated with a mean household size of 9 persons. The total cost and revenue were ₦64,808.0 and ₦125,000.0 per month, respectively, while the gross margin and net income for the sales of 50kg of smoked fish were ₦63,641.97 and ₦60,191.97, respectively per month. The profitability of selling smoked fish was positively and significantly impacted by household size, fish marketing experience and educational status of respondents who attained secondary school education at the 1% level. The study also found that gender, age of the respondent, cost of transportation and miscellaneous operating cost of smoked fish marketing had a negative influence on their net margin. Based on these findings, it is recommended that policies that will increase the level of education and participation of young people in fish trading should be encouraged and factored into policies related to fish production and marketing.
本文评估了翁多州Ilaje地方政府区熏鱼营销的盈利能力。采用多阶段随机抽样程序,采用结构良好的问卷,选择120名受访者。采用描述性统计、毛利率分析、效益成本比和生产函数等方法,利用普通最小二乘法对现场调查数据进行分析。调查结果显示,大多数营销人员的平均年龄在40岁左右。许多(90.0%)商贩为女性户主,具有14年的营销经验。调查结果显示,80%的受访者受过教育,平均家庭规模为9人。总成本和收入分别为每月64,808.0奈拉和125,000奈拉,而销售50公斤熏鱼的毛利率和净收入分别为每月63,641.97奈拉和60,191.97奈拉。销售熏鱼的盈利能力受到家庭规模、鱼类营销经验和受教育程度在1%水平的受访者的教育程度的显著正相关影响。研究还发现,受访者的性别、年龄、运输成本和熏鱼营销的杂项运营成本对他们的净利润率有负面影响。根据这些调查结果,建议应鼓励提高年轻人教育水平和参与鱼品贸易的政策,并将其纳入与鱼品生产和销售有关的政策。

: Ecosystem services are considered as essential factors to determine the quality of the wellbeing of populations. This research paper focuses on establishing the contributions of ecosystem services in ensuring food security and its subsequent impact on the socio-economic wellbeing of both men and women within the Volta Basin and what accounts for unequal access to ecosystem services by men and women. It also identifies the socio-cultural issues on ecosystem utilization within the given area. The approach employed for the gathering of data for this study was multi-disciplinary and local knowledge centered. Focus Group Discussions, household surveys, stakeholder consultative meetings, seminars and workshops and biophysical observations were the methods and tools employed in obtaining the needed data. Communities selected within the Volta Basin comprised Bawku West (Kokori through Aring to Binaba), Namdan District (from Sakote through Pelungu to Damolgo), Jirapa District (from Tuggo through Konzokala to Wulling) and Lawra District (from Dasuuri through Eramon Tangzu to Bompari). Findings from the study revealed that communities within the area of study relied on natural and human modified ecosystems to sustain and maintain human lives. The findings however established that traditional laws often provided land for women, wives, and widows through means other than, for instance, equal land shares on inheritance. Systemic gender biases existed in the form of customs, beliefs, attitudes and laws that confined women to cultivating some type of crops within the study communities. Also, most communities have lost their livestock as a result of theft and some farm fields have been destroyed by cattle grazing, making it difficult to access organic manure for farming resulting in the use of chemical fertilizer. Therefore, to ensure positive contribution of the ecosystems to food security, the study recommends that government should create regulations that strengthen tenure security in the majority of the studied locations. Also, efforts should be made to document and publicize benefits of gender inclusion in ecosystem service utilization. Studies should also be conducted on human attitudes and perceptions regarding ecosystem services as a tool for understanding the complex problems associated with environmental change in the context of cultural landscapes. Promote joint planning and consensus building with Fulani, farmers, decision makers and livestock owners to help solve the issue on livestock theft and over grazing.
生态系统服务被认为是决定人口福祉质量的基本因素。本研究论文的重点是确定生态系统服务在确保粮食安全方面的贡献及其对沃尔特盆地内男性和女性社会经济福祉的后续影响,以及导致男性和女性获得生态系统服务机会不平等的原因。它还确定了特定地区内生态系统利用的社会文化问题。本研究采用多学科、以本地知识为中心的方法收集数据。焦点小组讨论、住户调查、利益攸关方协商会议、研讨会和讲习班以及生物物理观察是获取所需数据所采用的方法和工具。沃尔特盆地内选定的社区包括包库西(从科科里到阿林到比纳巴)、南丹区(从萨科特到佩伦古到达莫尔戈)、吉拉帕区(从图戈到孔佐卡拉到武林)和劳拉区(从达苏里到埃拉蒙唐祖到邦帕里)。研究结果表明,研究区域内的群落依赖于自然和人类改造的生态系统来维持和维持人类的生活。然而,调查结果表明,传统法律通常通过其他方式向妇女、妻子和寡妇提供土地,例如,不是通过继承平等的土地份额。系统性的性别偏见以习俗、信仰、态度和法律的形式存在,限制妇女在研究社区内种植某种作物。此外,大多数社区因盗窃而失去了牲畜,一些农田因放牧而被毁,难以获得用于农业的有机肥,因此需要使用化肥。因此,为了确保生态系统对粮食安全的积极贡献,该研究建议政府应该制定法规,加强大多数研究地点的权居保障。此外,还应努力记录和宣传生态系统服务利用中性别包容的好处。还应研究人类对生态系统服务的态度和看法,以此作为了解在文化景观背景下与环境变化有关的复杂问题的工具。促进与富拉尼人、农民、决策者和牲畜所有者的联合规划和共识建立,以帮助解决牲畜盗窃和过度放牧问题。

Trial was led at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, India during rabi season of the years 2019-20 and 2020-21 to study the association of yield attributing traits in maize under INM treatments. Number of cobs per plant sowing highly significant positive correlation with the all-other traits under evaluation. Number of cobs per plant and Number of seeds per cob in the year 2019-20 showing positive significant genotypic correlation with the grain yield per plant whereas phenotypic correlation is non-significant. Evaluation of the maize with the same treatments for the two subsequent years and getting same result, suggesting efficacy of the experimental selection and validating the results. This study will provide early yield prediction by considering effect of INM treatments on yield attributes.
该试验于2019- 2020年和2020-21年拉比季节在印度古吉拉特邦阿南德阿南德农业大学农学院(College Agronomy Farm)进行,旨在研究INM处理下玉米产量归因性状的相关性。单株播种穗轴数与其他评价性状呈极显著正相关。2019- 2020年单株穗轴数和每穗轴种子数与单株籽粒产量呈显著正相关,而表型相关不显著。随后两年对相同处理的玉米进行评价,得到相同的结果,表明试验选择的有效性,验证了结果。本研究将综合考虑稻作处理对产量属性的影响,为早期产量预测提供依据。
