The purpose of this research is to examine the impact of rural-urban labor migration and remittances on rural agricultural productivity. A rigorous random selection process was used to pick 480 households from cross-sectional data. For this investigation, both primary and secondary data were used. Stata version 16 was used to examine both qualitative and quantitative data using descriptive (mean, standard deviation, and percentages) and econometric (three-stage least square technique) analyses. According to the descriptive data, the majority of respondents used their remittances for consumption, to acquire agricultural inputs, and to pay back their debts and tax payments. According to econometric studies, rural-urban migration has little influence on agricultural productivity. Remittances, cultivated land, livestock ownership, and extension services, on the other hand, have a positive and significant effect on agricultural productivity. In a nutshell, the link between migration, remittances, and agricultural output in agrarian and rural families is remarkable. Agriculture is the major source of income and mostly handles the liquidity issue. Agriculture production in the study region is labor intensive, and it is influenced by the amount of effort utilized in production as well as the socioeconomic characteristics of the household. As a result, it must address the major conundrum of agricultural productivity, particularly rural-urban migration and remittances. Address a knowledge gap, begin activities, and develop and implement multiple initiatives by various responsible stakeholders that are essential for the research topic. Furthermore, agricultural extension service delivery should be improved by timely recruiting, frequent agent training, and appropriate logistics.
本研究的目的是探讨城乡劳动力迁移和汇款对农村农业生产力的影响。采用严格的随机选择程序,从横截面数据中抽取了480户家庭。在这项调查中,我们同时使用了一手和第二手数据。使用Stata version 16使用描述性(平均值、标准差和百分比)和计量经济学(三阶段最小二乘技术)分析来检查定性和定量数据。根据描述性数据,大多数答复者将其汇款用于消费、购买农业投入、偿还债务和纳税。根据计量经济学研究,农村人口向城市迁移对农业生产力的影响不大。另一方面,汇款、耕地、牲畜所有权和推广服务对农业生产力具有积极和显著的影响。简而言之,移民、汇款与农业和农村家庭的农业产出之间的联系是显著的。农业是主要的收入来源,主要解决流动性问题。研究区域的农业生产是劳动密集型的,它受到生产中使用的努力量和家庭社会经济特征的影响。因此,它必须解决农业生产力的主要难题,特别是城乡移民和汇款问题。解决知识差距,开始活动,并由各种负责任的利益相关者制定和实施对研究主题至关重要的多项举措。此外,应通过及时招聘、频繁培训代理商和适当的物流来改善农业推广服务的提供。

Cowpea is an important grain legume crop used as feed for livestock, and its dry beans provide protein. Consequently, the objective of this study was to evaluate selected cowpea genotypes for herbage dry matter yield and nutritional quality in two agro-ecologies of the Benishangul-Gumuz region. The study was conducted at Kamashi and Assosa forages research stations of Assosa Agricultural Research Center, and the sites were purposively selected to represent lowland and midland agro-ecologies, respectively. Four cowpeas’ accessions (V. Unguiculata ILRI-11114, ILRI-12688, ILRI-12713, and ILRI-9333) and one check (Melka (ILRI-9334) as a check) were evaluated in a randomized complete block design with three replications. Herbage dry matter yield, plant height at forage harvesting, and days to maturity were significantly affected by location (L). Longer plant heights, shorter days to maturity, and higher dry matter yield ( P < 0.001 ) were recorded at Kamashi than at Assosa. Herbage dry matter yield was significantly P < 0.05 affected by year (Y), Y ∗ L (Y and L interaction), G ∗ L ∗ Y (genotype (G), L and Y interaction), and G ∗ L. Hebage dry matter yield was similar between years at Assosa, whereas at Kamashi significantly ( P < 0.001 ) different and more yields were obtained in 2015. The genotypes did not differ in nutritional quality parameters such as ash, acid detergent fibre, crude protein, and organic matter digestibility ( P > 0.05 ). However, neutral detergent fibre and acid detergent fibre were significantly ( P < 0.05 ) influenced by genotype. Thus, from the present study, it can be recommended that cowpea genotypes ILRI-12688 are suitable for Assosa and ILRI-11114 to Kamashi areas in terms of biomass production.
豇豆是一种重要的谷类豆科作物,用作牲畜饲料,其干豆提供蛋白质。因此,本研究的目的是评价本尚古尔-古木兹地区两个农业生态系统中选定豇豆基因型对牧草干物质产量和营养品质的影响。研究在阿索萨农业研究中心的Kamashi和Assosa饲草研究站进行,并有目的地选择分别代表低地和中部农业生态的站点。采用随机完全区组设计,3个重复评价4个豇豆材料(V. Unguiculata ILRI-11114、ILRI-12688、ILRI-12713和ILRI-9333)和1个检验材料(Melka (ILRI-9334))。牧草干物质产量、采草时株高和成熟期受地理位置(L)的显著影响,株高越高,成熟期越短,干物质产量越高(P < 0.05)。中性洗涤纤维和酸性洗涤纤维受基因型影响显著(P < 0.05)。综上所述,在生物量生产方面,ILRI-12688和ILRI-11114两种豇豆基因型分别适用于亚索萨和Kamashi地区。

Coffea arabica L., the dominant cash crop in the world market, is native to rain forest of Ethiopia where it is believed to exist with high genetic diversity. Estimating genetic parameters are momentous in deciding breeding method to be followed for crop genetic improvement including Arabica coffee. The study was conducted with the intention to gauge genetic gain trend in coffee yield and to select advanced promising lines of Yayo coffee landrace for the next breeding step. The study was laid down at Metu research subcenter in 2013, using 124 coffee accessions that were established in simple lattice design under two sets each comprising 62 accessions including two checks. The over six year’s pooled analysis of variance indicated the handiness variability in yield performance among accessions. Moderate genotypic variance (15.46 to13.56%), heritability (56.16–81%), and expected genetic gain (15.52–20.8%) were observed. The genetic parameters and the superiority of check in yield over accessions elucidated that high yielder variety development by selection is difficult unless heterosis attaining breeding method followed, particularly for these Yayo coffee landrace origin. Common high genetic gain trend (49.19 and 100 kg·ha−1) and response to selection (196.76 and 400 kg·ha−1), selection differential 471.9 and 739.23 kg·ha−1 were revealed in over four harvesting seasons mean value for both sets. Thus, selection is more effective in earlier season than late. High yielding accessions, Y27 and Y93, gave 3013.1 and 125.8 kg·ha−1 yield gain over the high yielder check correspondingly. Despite the top 15 and 10 high yielders were selected from set-I and set-II, respectively, a total of 20 accessions with contrasting desirable traits were selected and established in crossing block for genetic improvement purposes via heterotic hybrid variety development program. These accessions were tolerant to major coffee disease and have desirable agronomic traits.
阿拉比卡咖啡(Coffea arabica L.)是世界市场上主要的经济作物,原产于埃塞俄比亚的热带雨林,据信在那里存在着高度的遗传多样性。遗传参数的估算对于确定包括阿拉比卡咖啡在内的作物遗传改良育种方法具有重要意义。该研究旨在评估咖啡产量的遗传增益趋势,并为下一步育种选择有前途的优瑶咖啡地方品种。该研究于2013年在梅图研究分中心进行,使用124个咖啡添加物,这些咖啡添加物以简单的格子设计建立在两组中,每组包含62个添加物,包括两个检查。6年多的方差汇总分析表明,不同品种的产量表现存在较大的差异性。中度基因型变异(15.46 ~ 13.56%),遗传率(56.16 ~ 81%),预期遗传增益(15.52 ~ 20.8%)。遗传参数和产量比对资料的优势表明,除非采用杂种优势育种方法,否则通过选择培育高产品种是困难的,特别是对这些雅约咖啡地方品种。在4个收获季节平均值上,两组表现出共同的高遗传增益趋势(49.19和100 kg·ha−1)和对选择的响应(196.76和400 kg·ha−1),选择差异分别为471.9和739.23 kg·ha−1。因此,选择在季节前期比后期更有效。高产品种Y27和Y93比高产品种分别增产3013.1和125.8 kg·ha - 1。通过杂种杂交种培育计划,在杂交小区中分别筛选出了产量最高的15个和10个高产品种,并建立了性状比较理想的20个品种进行遗传改良。这些品种对主要咖啡病害具有耐受性,并具有理想的农艺性状。

The tomato is one of the most nutritious, economically important, and delicate vegetables grown in the world. It is highly susceptible to insect pests and microbial pathogens. The tomato leafminer moth, Tuta absoluta Meyrick, is the current impediment to tomato production in the world. The insect showed invasive and notorious behavior and was affecting tomato production. To control this insect, the application of synthetic insecticides is seen as the primary solution. However, during the feeding stage, larvae hide within mined leaf mesophyll and bored fruits from chemical spray, besides fast developing resistance to several insecticides. Such characteristics of the insect reduced the effectiveness of the chemical control efforts. Currently, the natural, or ecofriendly pest control method is gaining the momentum to minimize the application of synthetic insecticide against this devastating insect. Studies showed that botanical extracts (phytochemicals) and natural enemies such as parasitoids, predators, entomopathogenic nematodes, entomopathogenic fungi, and entomopathogenic bacteria are effective for controlling T. absoluta. As a result, the basic attributes of the above-mentioned natural agents and their potential to control T. absoluta have been briefly discussed in this review. However, due to disease (pests), the expected outcome for the subsectors is still low. Therefore, the pinpointing of major diseases and pests and their control measures would help to significantly improve the crop production technology used by smallholder farmers and thereby sustainably improve tomato production in Ethiopia.
西红柿是世界上最营养、最经济、最精致的蔬菜之一。它对害虫和微生物病原体高度敏感。番茄叶蛾(Tuta absoluta Meyrick)是目前世界上番茄生产的障碍。该昆虫具有入侵性和恶名性,严重影响番茄生产。为了控制这种昆虫,使用合成杀虫剂被认为是主要的解决办法。然而,在取食阶段,幼虫隐藏在化学喷雾开采的叶肉和钻孔果实中,并迅速对几种杀虫剂产生抗性。这种昆虫的这些特性降低了化学防治的效果。目前,自然或生态友好的害虫控制方法正在获得动力,以尽量减少对这种破坏性昆虫的合成杀虫剂的应用。研究表明,植物提取物(植物化学物质)和天敌如拟寄生虫、捕食者、昆虫病原线虫、昆虫病原真菌和昆虫病原细菌等都能有效防治绝对白蝇。因此,本文对上述天然药剂的基本特性及其防治白僵菌的潜力进行了简要的探讨。但是,由于疾病(害虫),分部门的预期成果仍然很低。因此,查明主要病虫害及其防治措施将有助于大大改进小农使用的作物生产技术,从而可持续地提高埃塞俄比亚的番茄产量。

Plant micropropagation research in Ethiopia requires concerted efforts to meet desired levels of application for sustainable utilization of the country's diverse plant genetic resources. The purpose of the present review is to provide an update on the results of plant micropropagation conducted so far in Ethiopia. It assessed their strengths and identified gaps in order to standardize research methods and indicate future research directions. Two cereals, three oil crops, three spices, five medicinal plants, two high-value crops, six fruit plants, nine root crops, and one endangered multipurpose shrub were reviewed. The assessment of previously published research was carried out in terms of methods used in the selection of ex plants and their disinfestations, culture vessels, and media used with a variety of combinations and concentrations of plant growth regulators, macro- and micronutrient requirements, culture environments, and genetic stability of regenerated plantlets. Further assessments include the utilization of plant growth-promoting microbes and applications of “omics” research in order to establish standardized, efficient, and cost-effective micropropagation techniques. The findings of the assessments are summarized and current advances are highlighted, along with recommendations for future plant micropropagation studies in the country.

Bread wheat is the world’s leading cereal grain, and more than one-third of the world’s population uses it as a staple food. The bread wheat production in Ethiopia is low compsssared to the national average yield, mainly due to the lack of high-yielding genotypes. This study was conducted during the 2019-2020 growing season to assess genetic variability and estimate the association of traits among bread wheat genotypes. The experiment consists of 49 bread wheat genotypes and is laid out in 7 × 7 simple lattice designs. The results showed significant differences ( p  < 0.01) among genotypes for most of the studied traits. Moderate genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) values were estimated for yield plant −1, thousand seed weight, and biomass yield. High heritability coupled with a high GAM was observed for thousand seed weight and yield plant –1. The grain yield showed a highly significant ( p  < 0.01) correlation with many yield-related traits at the phenotypic and genotypic levels. The biomass yield and the harvest index exerted the highest positive direct effect on grain yield at the genotypic level. The highest intercluster distance was observed between clusters I and IV (D2 = 31.86 ∗ ∗ ), followed by clusters II and IV (D2 = 29.21 ∗ ), and clusters II and III (D2 = 28.24 ∗ ), which indicated the chance of selecting a member of these clusters for hybridization. This experiment’s result indicates sufficient genetic variability among the tested genotypes, which provides ample scope for selecting superior and desired genotypes. Best-performed genotypes should be included in the future breeding program for further yield improvement. In conclusion, attention should be given to traits with moderate to high heritability and GAM, exerting a positive direct effect on the grain yield. However, the experiment should be repeated over locations and seasons to draw a definite conclusion.
面包小麦是世界上主要的谷物,世界上超过三分之一的人口将其作为主食。埃塞俄比亚的面包小麦产量与全国平均产量相比较低,主要是由于缺乏高产基因型。本研究在2019-2020生长季进行,旨在评估面包小麦基因型之间的遗传变异和性状关联。试验由49个面包小麦基因型组成,采用7 × 7简单格设计。结果表明,大部分性状基因型间差异极显著(p < 0.01)。估计了产量、千粒重和生物量产量的中等基因型变异系数(GCV)和表型变异系数(PCV)值。在千粒重和产量植株-1上,具有高遗传力和高GAM。在表型和基因型水平上,籽粒产量与许多产量相关性状呈极显著(p < 0.01)相关。在基因型水平上,生物量产量和收获指数对籽粒产量的直接正向影响最大。聚类I和聚类IV之间的簇间距离最大(D2 = 31.86∗),其次是聚类II和聚类IV (D2 = 29.21∗),聚类II和聚类III (D2 = 28.24∗),这表明在这些聚类中选择一个成员进行杂交的机会。本实验结果表明,所测基因型之间具有充分的遗传变异性,为选择优质和理想的基因型提供了充分的空间。为进一步提高产量,应将表现最好的基因型纳入未来的育种计划。综上所述,应重视对籽粒产量有直接积极影响的中高遗传力和GAM性状。然而,这个实验应该在不同的地点和季节重复进行,以得出明确的结论。

The bread wheat production in Ethiopia is low compsssared to the national average yield, mainly due to the lack of high-yielding genotypes. This study was conducted during the 2019-2020 growing season to assess genetic variability and estimate the association of traits among bread wheat genotypes. The experiment consists of 49 bread wheat genotypes and is laid out in 7 × 7 simple lattice designs. The results showed significant differences (\u0000 \u0000 p\u0000 \u0000  < 0.01) among genotypes for most of the studied traits. Moderate genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) values were estimated for yield plant −1, thousand seed weight, and biomass yield. High heritability coupled with a high GAM was observed for thousand seed weight and yield plant –1. The grain yield showed a highly significant (\u0000 \u0000 p\u0000 \u0000  < 0.01) correlation with many yield-related traits at the phenotypic and genotypic levels. The biomass yield and the harvest index exerted the highest positive direct effect on grain yield at the genotypic level.

Agriculture continues to be vital to Africa’s future in both spatial and temporal contexts. Nonetheless, the sector keeps on confronting production challenges as a result of frequent and extended droughts, and these necessitate the use of drought-resistant crops such as sorghum. This review initiates one of the most common food grains grown in the poorest countries and the most food-insecure regions of the nation. We used deductive logical reasoning to develop a comprehensive scientific understanding of the crop that can be used to inform future research and policies. Various exclusion and inclusion criteria were used to filter the most prominent findings. Sorghum has the highest utility for its climatic adaptability and has grown for multiple purposes: From staple to industrial outcomes, its economic, social value, and health outcomes, and for animal silage. It is a gluten-free crop, has high nutritive value, and is preferred by healthy consumers. It is among the top five cereal crops worldwide in both production and acreage. This has necessitated the development of coping measures, such as the cultivation of drought-tolerant crops suitable for the affected areas. Therefore, this crop is used to ensure productivity, food security, and availability of food when other crops fail and food deficit and famine are affected in the region. This will contribute to the ongoing discussion on how to better inform private and public sector policy and investments in Ethiopia to increase sorghum and other drought-tolerant crop production, transform agriculture, improve nutrition, and food systems, and end hunger, food insecurity, and poverty.
从空间和时间的角度来看,农业对非洲的未来仍然至关重要。尽管如此,由于频繁和持续的干旱,该部门继续面临生产挑战,这就需要使用高粱等抗旱作物。本综述提出了一种最常见的粮食谷物,种植在最贫穷的国家和粮食最不安全的地区。我们使用演绎逻辑推理对这种作物进行了全面的科学理解,可用于为未来的研究和政策提供信息。使用各种排除和纳入标准来过滤最突出的发现。高粱因其气候适应性而具有最高的效用,并被用于多种用途:从主食到工业产品,其经济、社会价值和健康结果,以及动物青贮。它是一种无麸质作物,营养价值高,是健康消费者的首选。无论是产量还是种植面积,它都是世界上排名前五的谷类作物之一。这就需要制定应对措施,例如种植适合受影响地区的耐旱作物。因此,当该地区其他作物歉收、粮食短缺和饥荒发生时,这种作物被用来确保生产力、粮食安全和粮食供应。这将有助于正在进行的关于如何更好地为埃塞俄比亚私营和公共部门的政策和投资提供信息的讨论,以增加高粱和其他耐旱作物的生产,改造农业,改善营养和粮食系统,以及消除饥饿、粮食不安全和贫困。

A field experiment was conducted at Nono Benja District from December 2013 to May 2014 under irrigation to assess the response of different sizes of seed tubers and intra-row spacing on the yield and quality of potato varieties. The treatments consisted of a factorial combination of two varieties (Jalenie and Gudenie): five levels of tuber size (20–35, 36–50, 51–65, 66–80, and 81–95 g) and five levels of intra-row spacing (20, 25, 30, 35, and 40 cm). The treatments were arranged in a split-split plot design (variety on main plot, intra-row spacing on subplot, and tuber size on sub-sub plot) with three replications. There were significant interaction effects of variety, intra-row spacing, and tuber size ( P < 0.05 ) on plant height, number of main stems per plant, average tuber weight, tuber number per plant, total tuber yield, marketable tuber yield, unmarketable tuber yield, large tuber mean yield, medium tuber mean yield, and small tuber mean yield. Variety of tuber size and intra-row spacing was also influenced by dry matter content and tuber specific gravity. The interaction effect of intra-row spacing and seed tuber size was significantly ( P < 0.05 ) influenced by the number of days to emergence. The day to flowering was also significantly ( P < 0.05 ) influenced by the interaction effect of variety and intra-row spacing. The maximum plant height (80.38 cm) was recorded with variety Gudenie with a tuber size of 66–80 g and planted at an intra-row spacing of 35 cm. The maximum (9.79) number of main stems was recorded in variety Jalenie with a tuber size of 81–95 g and planted at intra-row spacing of 40 cm. The maximum of total tuber yields (24.84 to/ha) was recorded from Jalenie variety with tuber size 66–80 g and planted at intra-row spacing of 25 cm. The maximum (10.18 t/ha) larger tuber was recorded with variety Gudenie with a tuber size of 66–80 g and planted at 25 cm. Variety Jalenie with tuber size of 66–80 g and planted at 25 cm produced the maximum (8.04 t/ha) medium-sized tubers. The maximum small tuber (8.59 t/ha) was recorded from both varieties with intra-row spacing of 20 cm and tuber size 81–95 g. Variety Gudenie planted at intra-row spacing of 40 cm gave higher (19.98%) dry matter content, and variety Gudenie with a tuber size of 66–80 g gave higher (20.61%) dry matter content. The higher (1.077) tuber specific gravity was obtained with variety Gudenie planted at intra-row spacing of 35 and 40 cm, and the higher (1.074) tuber specific gravity was registered with variety Gudenie with a tuber size of 66–80 g and/or 81–95 g and planted at intra-row spacing of 40 cm. The study needs in-depth investigation by repeating in multilocations with more seasons, varieties, processing quality, and other agronomic practices of the crop to reach a conclusive recommendation. The result of this research was presented to Jimma University since 2015.
2013年12月至2014年5月,在诺诺本佳区进行了灌溉条件下的田间试验,研究了不同种块茎大小和行距对马铃薯品种产量和品质的影响。处理包括两个品种(Jalenie和Gudenie)的因子组合:块茎大小5个水平(20 - 35、36-50、51-65、66-80和81-95 g)和行间距5个水平(20、25、30、35和40 cm)。处理采用裂裂小区设计(品种在主小区,行间距在次小区,块茎大小在次小区),设3个重复。品种、行距和块茎大小对株高、单株主茎数、平均块茎重、单株块茎数、总块茎产量、可售块茎产量、不可售块茎产量、大块茎平均产量、中块茎平均产量和小块茎平均产量均有显著互作效应(P < 0.05)。干物质含量和块茎比重对块茎大小和行间距的变化也有影响。行距与块茎大小的互作效应受出苗期影响显著(P < 0.05)。品种和行距的互作效应对开花日数也有显著影响(P < 0.05)。块茎大小为66 ~ 80 g、株距为35 cm的古德尼品种株高最高,达到80.38 cm。块茎大小为81 ~ 95 g、株距为40 cm的Jalenie品种主茎数最多(9.79)。以块茎大小66 ~ 80 g、株距25 cm的Jalenie品种块茎总产量最高,为24.84 /ha。块茎最大(10.18 t/ hm2)的品种为Gudenie,块茎大小为66-80 g,种植高度为25 cm。品种Jalenie块茎大小为66-80克,种植高度为25厘米,块茎产量最高(8.04吨/公顷)。两个品种的最大小块茎产量为8.59 t/ha,行距为20 cm,块茎大小为81 ~ 95 g。行距为40 cm时干物质含量最高(19.98%),块茎大小为66 ~ 80 g时干物质含量最高(20.61%)。以35和40 cm行距种植的古登尼品种块茎比重最高,为1.077;块茎大小为66 ~ 80 g和(或)81 ~ 95 g,行距为40 cm种植的古登尼品种块茎比重最高,为1.074。这项研究需要通过在不同季节、品种、加工质量和其他作物农艺实践的多个地点重复进行深入调查,以得出结论性建议。该研究结果自2015年起提交给吉马大学。

Effect of Blended NPSB and Nitrogen Application rates on Growth, Yield, and Yield Components of Bread Wheat (Triticum aestivum L.) at Gitilo Dale Research Site of Wallaga University, Western Ethiopia 在埃塞俄比亚西部瓦拉加大学Gitilo Dale研究基地混施氮肥和氮肥对面包小麦生长、产量和产量组成的影响

Wheat (Triticum aestivum L.) is a very important cereal crop widely produced and consumed in almost all parts of Ethiopia. However, due to abiotic and biotic stresses, its productivity is low as compared to the world average. Among these, soil fertility and unbalanced application of plant nutrients are the major constraints that limit the productivity of the crop in sub-Saharan African countries especially Ethiopia. As a result, an experiment was carried out at the Gitilo Dale Research Site of Wallaga University to determine the combined impact of blended NPSB and urea fertilizers on the growth, yield, and yield-related variables of bread wheat. The experiment used a factorial-arranged in randomized full block design with two factors with four levels each: NPSB (0, 100, 150, and 200 kg·ha−1) and nitrogen (urea) (0, 31.1, 71.65, and 112.2 kg·ha−1) (RCBD). With three replications, there were sixteen treatments. A test crop of the bread wheat variety liben (ETBW 5653) was grown. The phonological and growth parameters of bread wheat were significantly affected by NPSB and nitrogen applications as well as their interactions except for days to 50% emergence. The primary and interaction impacts of NPSB and nitrogen rates affected the yield and all of its constituents, except the number of kernels per spike. The application of 200 kg·ha−1 NPSB plus 112.2 kg·ha−1 nitrogen treatment resulted in the highest above-ground biomass production of bread wheat (12481.00 kg·ha−1), grain yield of 5182.51 kg·ha−1, and a straw yield of 7298.40 kg·ha−1. Hence, to maximize the yield of bread wheat, applying 200 kg·ha−1 of chemically blended NPSB with 112.2 kg·ha−1 nitrogen is recommended rather than applying any straight and complex fertilizers having only macronutrients.
小麦(Triticum aestivum L.)是一种非常重要的谷类作物,在埃塞俄比亚几乎所有地区广泛生产和消费。然而,由于非生物和生物压力,其生产力与世界平均水平相比较低。其中,在撒哈拉以南非洲国家,特别是埃塞俄比亚,土壤肥力和植物养分施用不平衡是限制作物生产力的主要制约因素。为此,本研究在瓦拉加大学Gitilo Dale研究基地开展了一项试验,以确定NPSB与尿素混合施用对面包小麦生长、产量及产量相关变量的影响。试验采用因子随机全区设计,2个因子各设4个水平:NPSB(0、100、150和200 kg·ha−1)和氮素(尿素)(0、31.1、71.65和112.2 kg·ha−1)(RCBD)。有3个重复,有16个治疗。种植了面包小麦品种立本(ETBW 5653)的试验作物。除出苗期d ~ 50%外,施氮和氮肥对面包小麦的音系和生长参数有显著影响。NPSB和施氮量的主要影响和交互作用影响了产量及其所有成分,但每穗粒数除外。施用200 kg·ha - 1 NPSB + 112.2 kg·ha - 1氮肥处理的面包小麦地上部生物量产量最高(12481.00 kg·ha - 1),籽粒产量为5182.51 kg·ha - 1,秸秆产量为7298.40 kg·ha - 1。因此,为了最大限度地提高面包小麦的产量,建议施用200 kg·ha - 1的化学混合氮肥和112.2 kg·ha - 1的氮肥,而不是施用只含有大量营养元素的直接和复杂肥料。

The growing human population is a driver for higher food demands with a need to scale agricultural production and maintain security of the food supply chain. Thus, there is a need to increase the adoption and improvement of mechanized systems in agriculture, especially where needed labor is also drifting into nonagricultural production sectors. With this view, the relationship or link between population and employment in nonagricultural sector in Ghana (West Africa) to agricultural mechanization was tested to ascertain any such validity. This formed the primary basis for this study and furthered on to establish the current level of agricultural mechanization within the country through measuring effect of available farm energy sources on farm sizes under cultivation. The methods employed included a structured questionnaire administered to farmers and other agricultural stakeholders to determine the level of mechanization, readiness to adopt/accept mechanization technology, level of usage of mechanization technologies, and ownership of machinery. The Statistical Package for the Social Sciences (SPSS version 20) software was used to model and analyze data obtained including a multiple regression method for the relationship between parameters. The overall level of agricultural mechanization in Ghana was found to be very low with 77.6% of the farm operations being performed manually. The level of the tractor power availability in Ghana was found to have increased from 0.0207 kW/ha in the year 2004 to 0.0588 kW/ha in the year 2020 and is expected to increase to 0.0752 kW/ha in the year 2025. The power availability valued in this study was also found to be low compared with that in other developing countries.

不断增长的人口推动了更高的粮食需求,需要扩大农业生产并维持粮食供应链的安全。因此,有必要增加农业机械化系统的采用和改进,特别是在所需劳动力也流入非农业生产部门的地方。根据这一观点,对加纳(西非)非农业部门的人口和就业与农业机械化之间的关系或联系进行了检验,以确定是否存在这种有效性。这构成了本研究的主要基础,并进一步通过测量可用农场能源对耕种农场规模的影响来确定该国目前的农业机械化水平。采用的方法包括对农民和其他农业利益相关者进行结构化问卷调查,以确定机械化水平、采用/接受机械化技术的准备程度、机械化技术的使用水平和机械所有权。使用SPSS version 20软件对所得数据进行建模和分析,并采用多元回归方法对参数之间的关系进行分析。加纳农业机械化的总体水平非常低,77.6%的农场作业是手工完成的。加纳的拖拉机可用功率水平已从2004年的0.0207千瓦/公顷增加到2020年的0.0588千瓦/公顷,预计到2025年将增加到0.0752千瓦/公顷。与其他发展中国家相比,本研究中所重视的电力供应也很低。统计上,服务业就业和人口增长都是加纳农业机械化水平变化的重要决定因素(调整后- r2 = 0.9172),政策制定者将不得不调整政策,以注意这些最常被低估的指标。提高农业机械化水平的倡导必须加强,因为这对农业生产的总体成本至关重要,因为这项研究还发现,机械化操作比人工操作便宜21.3%至53.8%。

Thus, there is a need to increase the adoption and improvement of mechanized systems in agriculture, especially where needed labor is also drifting into nonagricultural production sectors. With this view, the relationship or link between population and employment in nonagricultural sector in Ghana (West Africa) to agricultural mechanization was tested to ascertain any such validity. This formed the primary basis for this study and furthered on to establish the current level of agricultural mechanization within the country through measuring effect of available farm energy sources on farm sizes under cultivation. The methods employed included a structured questionnaire administered to farmers and other agricultural stakeholders to determine the level of mechanization, readiness to adopt/accept mechanization technology, level of usage of mechanization technologies, and ownership of machinery. The Statistical Package for the Social Sciences (SPSS version 20) software was used to model and analyze data obtained including a multiple regression method for the relationship between parameters. The overall level of agricultural mechanization in Ghana was found to be very low with 77.6% of the farm operations being performed manually. The level of the tractor power availability in Ghana was found to have increased from 0.0207 kW/ha in the year 2004 to 0.0588 kW/ha in the year 2020 and is expected to increase to 0.0752 kW/ha in the year 2025. The power availability valued in this study was also found to be low compared with that in other developing countries.
