description: Overview This dataset contains the data of the three databases "Deutsch-Französische Kunstvermittlung 1870-1940, Paris", "Deutsch-Französische Kunstvermittlung 1870-1940/44, Berlin" and "Deutsch-Französische Kunstvermittlung 1945-1960, Paris" as Spreadsheets and a JSON-document as well as a platform to display the data. The data was gathered and entered into former databases between 1999 and 2005. In 2019 the data was migrated to a MySQL-database and in 2021 the MySQL-database was exchanged by Elasticsearch. Research data The data was gathered and entered into three former databases between 1999 and 2005 and in the realm of two research projects. Both projects were carried out by the DFK Paris in cooperation with the Kunsthistorisches Institut, Freie Universität Berlin. The principal Investigator of both projects was Thomas W. Gaehtgens. From 2021 to 2022 the data has been semantically enriched and the presentation on the website has been redesigned. These measurements were part of a project led by Anne Klammt. Software In general, this platform allows the integration of that data into web based systems such as content management systems. To be independent of the target technology, the integration is implemented with a set of customized HTML tags with no assumptions on lower layers.

title: Screening Mung bean [ Vigna radiata (L.) Wilczek] Genotypes for Drought Tolerance

description: Drought is among the major constraints in mung bean production. The main goal of the current study was to investigate the response of 60 mung bean genotypes to two constrasting moisture regimes using diverse indices. The experiment was made at Jinka Agricultural Research Center using a 6 x 10 alpha lattice design replicated twice. Correlation analysis revealed that seed yield under stressed condition was positively correlated with stress tolerance index (STI), yield index (YI), harmonic mean (HM), mean relative performance (MRP), and relative drought index (RDI). PCA of the first two components accounted for 93.4% of the total variations where PC1 contributed for 64.39% of the variations. Based on cluster analysis, 60 mung bean genotypes used in the current study were grouped into five distinct clusters. In conclusion, this study showed that selection based on indices with seed yield under moisture stress (Ys) and seed yield under non moisture stress (Yp) conditions are useful for mung bean breeders. Therefore; stress tolerance index (STI), yield index (YI), harmonic mean (HM), geometric mean productivity (GMP) and mean relative performance (MRP) were found to be more suitable indices since these indices had the highest correlation with seed yield under both moisture stressed and non moisture stress conditions.

title: Effect of Zinc Fertilizer Rates on Grain and Straw Zn Content, and Grain Yield of Chickpea Varieties in Southern Ethiopia

description: Application of Zn had a significantly positive effect on grain Zn concentrations and also on grain yield especially under Zn deficient conditions. The amount of Zn required to alleviate Zn deficiency varied with severity of deficiency, soil types, nature of crops and cultivars. The response of chickpea varieties to Zn nutrition was studied in pots and on fields using zinc deficient soils during 2012 and 2013 cropping seasons to determine zinc fertilizer rate which improve zinc content and productivity of the crop. A factorial combination of three chickpea varieties and seven zinc fertilizer rates were laid in Randomized Complete Block design with three replications for both pot and field experiments. The result of pot experiment revealed that, variety Mastewal produced the highest grain yield (5.9 g pot-1) and Habru produced highest (35.99mg kg-1) straw zinc content. Conversely, local chickpea provided the highest (36.1mg kg-1) grain Zn. Chickpea varieties and zinc fertilizer rates interaction on grain yield was significant where 25kg ha-1 produced highest regardless of the varieties. Similarly, location had significant (p&lt;0.01) effect of grain zinc content where Choroko produced 46.6 % more grain zinc content than both Taba and Jolle. Highest straw zinc (24.96 mg kg-1) obtained from variety Habru, while highest grain zinc obtained from the application of 25 kg ZnSO4 .7H2O ha-1 with either of the varieties which was at par with the highest Zinc rate (30kg ha-1). Significant interaction effect of variety by location on grain yield and straw zinc content was observed. The variety Mastewal was superior in grain yield at Jolle and Choroko, while landrace performed better at Taba. The landrace and Habru were higher in straw zinc content across locations. Moreover, 25 kg ZnSO4 .7H2O ha-1 resulted in 7 and 8% more grain and straw zinc content over the control, in that order. Thus, the current research inveterate a possibility of agronomic intervention for zinc fortification of chickpea through zinc fertilizer management.

title: The A meliorative Effects of O rganic and I norganic Fertilizer s on Yield and Yield Components of Barley and Soil Properties on N itisols of Central Ethiopian Highlands

description: A field experiment was conducted for three consecutive cropping seasons (2015-2017) on farmers’ fields in Welmera, Ada’a Berga and Ejere district of Oromiya Regional State. The objectives of this study were to evaluate the influence of organic and inorganic fertilizers on growth and yield of barley and soil chemical properties. The treatments included eleven selected combinations of organic and inorganic nutrient sources, including farmyard manure (FYM), vermicompost, compost, nitrogen (N), phosphorus (P) and boron (B). The design was randomized complete block with three replications. Results showed that barley yield and yield components, and soil chemical properties were significantly affected by the application of organic and inorganic fertilizer sources. The highest barley grain yield of 4277 kg ha-1 was obtained from the applications of half doses of vermicompost (3.8 t ha-1) based on the recommended N equivalent and half doses of the recommended N and P fertilizers (30 kg N ha-1 N and 34.5 P2O5 kg ha-1), followed by 3911 kg ha-1 due to the application of the full recommended inorganic N and P fertilizers (60 kg N ha-1 and 69 kg P ha-1). The highest biomass yield of 9937 kg/ha was obtained from the applications of the full recommended N and P rates (60 kg N ha-1 and 69 kg P2O5 ha-1). Application of organic fertilizer significantly improved soil organic carbon from 1.26 % to 1.56%, N from 0.14% to 0.23% and phosphorous from 7.84 mg kg-1 to 12.59 mg kg-1. The result also showed that the highest marginal rate of return was obtained from the application of 50% vermicompost based on N equivalent) + 50% N and P, which is economically the most feasible alternative on Nitisols of central Ethiopian highlands.

title: Exploring Optimized Synergetic Solutions for Major Constraints of Sustainable Agricultural Production in Chencha, Southern Ethiopia

description: Several constraints affect the performances of the farming system in Chencha suggesting the necessity of adjustments in the farm components. Therefore, an exploration was made to simultaneously optimize operating profit, labour and soil organic matter balances. Data from twelve farms and secondary data on improved technologies were used as bases for the exploration. Using the multi-objective model FarmDESIGN, the optimization was conducted for two scenarios for each farm, i.e., optimization based on the currently existing farm components and practices and by introducing new technologies and practices to amend the current farm management options. The results revealed that the farm operating profit, labour balance and organic matter balance were not yet optimized with the current farm configurations of all farms. But there is ample scope to improve and simultaneously optimize both the economic, social and environmental sustainability either through optimization of management within current farm resources, or through using improved technologies. The highest improvement could be made through combined optimization of management within current farm resources and improved technologies. The major important factor that influenced the optimization was the cropping plan, which might be associated with the management practices applied for a particular crop. However, adjusting areas of crops and implementation of some other optimized solutions may be difficult for individual farmers and requires advice through agricultural extension programmes. Therefore, there is a need to improve the awareness of farmers to wisely manage: crop area and associated crop and soil management practices, land use for eucalyptus, straw use and storage of farm yard manure. Moreover, it is important to diversify off-farm income sources, introduce alternative threshing machineries and improve market access for farm products.

title: Integrated effect of Furrow Irrigation Methods and Types of Mulches on Yield and Water Productivity of Maize (Zea mays L.) in Hawassa, Ethiopia

description: Efficiency of water can be improved by making the right decision regarding to irrigation scheduling, irrigation application techniques and conservation mechanisms. A field experiment was conducted in a dry season of 2018 to investigate the effects of mulch types and water application methods in furrow irrigation system on water productivity, and yield and yield components of maize (Zea mays L.) at Hawassa, Southern Ethiopia. Factorial combinations of three types of furrow irrigation methods (alternate, fixed and conventional) and three mulch types (no mulch, plastic, and straw mulch) were laid out in split-plot design with furrow irrigation methods as main plot and mulching as sub-plot and replicated three times. Results indicated that different types of furrow irrigation methods had a very highly significant effect on plant height, cob length and weight, aboveground biomass, grain yield, and water use efficiency of maize. Types of furrow irrigation method highly significantly affected thousand grain weight and harvesting index. Moreover, maize growth, yield and yield components including water productivity were highly significantly influenced by different mulch types. However, irrigation method by mulching type interaction was not significant for any of the studied parameters). Significantly higher yield and yield component of maize were recorded from conventional furrow irrigation method than alternate and fixed furrow irrigation method. The highest maize grain yield of 9003.8 kg ha-1 was achieved from conventional furrow irrigation water management method. However, higher water productivity (2.43 kg/m3) was obtained from alternate furrow irrigation method. Moreover, higher yield and yield components including water use efficiency were obtained from plastic mulch than no mulch and straw mulch. The maximum grain yield of 8088.9 kg ha-1 and water productivity (2.34 kg/m3) were obtained from plastic mulch, but the partial budget analysis revealed that straw mulch was more economically feasible for farmers than plastic mulch for maize production at Hawassa area. Therefore the present study suggests that, for maximizing grain yield under no water stress scenario, irrigation of maize with conventional furrow irrigation methods could be used. On the other hand, under limiting irrigation water condition, alternate furrow irrigation method with straw mulch application could be used to minimize evaporation loss and maximize water productivity and yield of maize at Hawassa and similar agro-ecology and soil type.

title: Mineralogical and Physicochemical Properties of Nitisols In The Ethiopian Highlands

description: Nitisols cover an extensive area of the agricultural landscape in the Ethiopian highlands. This study outlines the morphological and physico-chemical properties, and the mineralogical and total elemental composition of some Nitisol profiles based on soil survey at 250 m resolution. Analytical data of 46 Nitisol profiles were studied for soil pH, organic carbon (OC) and some macro and micronutrients, and mineralogical and total elemental composition. Results showed that Nitisols of the Ethiopian highlands differ in some fundamental ways from the pedogenetic characteristics often referred to in the mainstream soil science literature. The soils in this study are strongly to moderately acidic with pH of 4.8-6.7, and very low in OC, TN and sulfur (S) with mean values of 2.05%, 0.18% and 0.94 mg/kg. But levels of available phosphorus (AP) and exchangeable K showed wide variation (2.40 to 26.40 mg/kg P and 0.07 to 2.77 cmol (+)/kg K), reflecting differences in parent materials and land use. Considering micronutrients, the soils are very high in iron (Fe), manganese (Mn) and zinc (Zn) but severely deficient in copper (Cu) and boron (B). Conversely, the soils are very high in CEC (mean 41.93, range 26-57 cmol (+)/kg) and base saturation (mean 73%, range of 50-95%), and mean silt/clay ratio of 0.38 in the Ap horizon is rated high. Mineralogical composition of primary minerals (chiefly feldspars) and 2:1 phyllosilicates (mainly mica) in the clay fraction, suggests that the soils are still young and cannot be qualified as “highly weathered soils” in contrast with other tropical Nitisols. At a local level, the results suggest that sustainable agricultural production on these soils depends on the replenishment of organic matter and application of fertilizers in proper balance and right amounts. Also, the distinct characteristics of Nitisol profiles described provide additional diagnostic criteria to distinguish subunits of Nitisols (i.e., third level) under the WRB system of classification.

title: Aflatoxin Contamination of Ethiopian Hot Red Pepper and Risk Characterization: Dietary Exposure Assessment and Estimated Aflatoxin-Induced Hepatocellular Carcinoma

description: Aflatoxins are toxic fungal secondary metabolites, and their presence in the food chain can cause adverse health effects, impair trade and pose a significant economic burden. This study analyzed aflatoxin contamination along a hot pepper postharvest value chain, estimated its dietary exposure and its associated potential health risk to consumers. A total of 25 composite samples were analyzed for aflatoxins using immunoaffinity column cleanup and HPLC. Aflatoxins were detected in 48 % of the tested samples. Aflatoxin G1 was recorded at highest frequencies and contamination levels followed by AFB1. Uppermost contaminations (μg/kg) were recorded from packed pepper powder (43.61 AFG1 and 22.18 AFB1) followed by unpacked pepper powder (30.53 AFG1 and 13.50 AFB1). Five (42 %) of the positive samples exceeded the EU regulatory limits for AFB1 (&gt; 5 μg/kg). Aflatoxin detection frequencies, aflatoxin types and contamination levels generally increased up along the chain. The mean daily intake dose was found as 1.04 ng AFB1/kg bw/day and the cancer risk was estimated to be 0.0188, 0.0098 and 0.0286 cancer cases/year/100,000 population of hepatitis B surface antigen positive, negative and adult subpopulation, respectively. This cancer risk level can be considered “essentially negligible” as compared to 1 x 10-5 cancer risk level established by some agencies. However, as this study was dependent on a single food commodity, and aflatoxin contamination level varies from year to year and location to locations, the risk level of this study should not be taken as assurance for safe risk level. In addition, if aggregate dietary exposure is considered, possible health risk would be high. In conclusion, the increased trends of detection frequencies, aflatoxin types and contamination levels up along the value chain signified the possible occurrence of the toxin and their associated health risk as the food commodity approaches consumption. Because complete elimination of aflatoxin is almost unachievable once contamination has happened, preventative management efforts should target the value chain.

title: The Role of Conservation Agriculture for Soil Quality Improvement: A Review

description: Ethiopia experiences a very high soil loss of 40–130 t ha-1year-1 from croplands that costs the country about 1.0-1.5 million tons loss of grain production per year. Founded on its three interlinked principles, Conservation Agriculture (CA) is widely documented to reduce soil loss, improve soil quality and contribute to sustainable agricultural production. Despite more than three decades of research and promotion efforts on CA in Ethiopia, long-term comprehensive studies are scanty to sufficiently demonstrate its benefits for soil quality enhancement. Drawing lessons from long-term CA studies both within and outside the country would help to make informed decisions for wider use of CA and guide future research and promotion activities. Available pertinent CA literatures from peer-reviewed journals, research reports, dissertations, and proceedings were reviewed. This review was aimed to collate and analyse studies documented the effect of CA practices on soil quality improvement and associated challenges, and suggest the way forward for its application by smallholder farmers in Ethiopia. The review indicated that, when properly implemented, CA improves soil quality in 3-5 years and contributes to sustainable agricultural production. Besides, yield improvement is possible in early stages of CA application in the low moisture areas under sufficient crop residue retention. However, CA adoption in Ethiopia is generally low which is mainly attributed to limited availability and competing uses of crop residue, limited availability and use of CA based recommendations, mis-location of CA promotions, limited participatory extension services and enabling conditions. Overall, the review suggested the need for a concerted multi and inter-disciplinary research effort to develop CA innovations suiting to the different biophysical environments and socioeconomic circumstances. Effectively demonstrating the power of CA on relieving soil problems, and providing alternative solutions for the challenges surrounding it are requisites to get its full benefits. Capacity building on innovative CA practices is crucial for researchers, extension workers, development practitioners and the smallholder farmers

title: Thermal Inactivation Kinetics of Aflatoxigenic Aspergil-lus flavus and A. parasiticus Conidia Isolated from Ethiopian Hot Red Pepper Powder

description: Thermal food processing is known to inactivate harmful microorganisms in foods. However differ-ent microbes have varying degrees of heat resistance. During this study, thermal inactivation characteristics of aflatoxigenic Aspergillus flavus and A. parasiticus conidia isolated and charac-terized from Ethiopian hot red pepper powder were determined by the survivor curve method in digital water bath to realize their fate and stability under thermal food processing. The experiment was done at 55, 65, 75, 85 and 95 oC with exposure time of 30, 45, 60, 75 and 90 min., and also at different NaCl concentrations for A. flavus. The D-values for A. flavus and A. parasiticus ranged from 119.1-14.1 and 147-17.1 min. respectively with Z-values of 35.2 and 34.4 oC in the written order. Both fungi were found sensitive to the moist heating following the first-order kinetics model. Aspergillus parasiticus was found resistant than A. flavus. The D-values for A. flavus at 2-8 % NaCl ranged from 119.7-188.6, 36.1-41.5, 29.6-32.9, 20.4-21.7 and 45.6-48.9 min. at 55, 65, 75, 85 and 95 oC, respectively. The NaCl decreased thermal sensitivity of the conidia and affected the linearity of inactivation. These results may serve as baseline information for postharvest pepper-based food preservation. However, for its practical application, we recommend further detailed studies on respective food processing practices and food matrix.

title: Sensory Quality Attributes of Tef [Eragrostis tef (Zucc.) Trotter] Injera as Influenced by Genotype and Environment

description: Tef is used to make injera (bubbly, pancake-like bread). It is believed that the white color tef grain produced in the central highlands of Ethiopia fetches the highest price as compared to the other areas due to its injera quality. Therefore, this experiment was conducted in the central and northwestern highlands of Ethiopia to evaluate Injera Sensory Quality Attributes (ISQA) on the three white-colored tef genotypes (Etsub, Magna, and Quncho) produced on five environments and to assess its relationship with edaphic factor, climatic factor, and grain and flour color of tef. The responses of the 21 knowledgeable consumer panelists' for top surface color, bottom surface color, malleability, eye appearance, and general rating; and 11 of them for taste subjected to Analysis of Variance (ANOVA). The ANOVA result showed that except taste significantly (P &lt; 0.05) different only on the environment, other ISQA were significantly (P &lt; 0.05 to P &lt; 0.001) different on the genotype, environment, and genotype by environment interaction effects. The variance component result revealed that the environment (52.4%, 38.7%, 62.5%, 87.6%, 69.0%, and 80.8%) and genotype (40.9%, 53.0%, 26.0%, 12.0%, 28.6%, and 18.6%) contribution to the variation of BSC, TSC, eye appearance, Malleability, taste, and general rating were high, while the genotype was low (6.6%, 8.3%, 11.6%, 0.3%, 2.4% and 0.6%). There were also significant positive correlations of soil properties (black color/vertisols pH, CEC, ca, Mg, and K), grain and flour color V value, and altitude; while soil total nitrogen and sulfur as well as precipitation showed an indirect significant relationship with IQSA. These results concluded that tef grown on vertisols with slightly acidic to neutral soil pH and relatively high in basic cations have a better quality of injera as compared to tef grown in nitisols with low soil pH and basic cations. Based on our results, we argued that the quality of tef injera “as low quality” grown in Vertisols of the northwestern highlands couldn’t be substantiated. A further study under controlled environment is recommended to evaluate the effects of different soil nutrients effect on ISQA under different soil types and agro-ecologies of Ethiopia.
