Challenges related to statistical methods and sensor systems for the daily prediction of health disorders in individual dairy cows
(2023-02-02)The use of digital support systems has become a standard in dairy farming, and significant effort has been made to detect individual animals that are in need for a treatment by using sensor data. However, developing systems ... -
Development of root phenotyping methods and QTL analysis of root traits in grapevine mapping populations
(2023-01-30)Facing climatic change and upcoming extreme weather events require the adaptation of agricultural crops to conditions like extended drought periods in the future. Therefore, the incorporation of promising morphological and ... -
The effectiveness and efficiency of forest conservation policies to reduce deforestation in the Peruvian Amazon
(2023-01-23)Between 2015 and 2020, 9.3 million hectares of tropical forests were annually deforested. Deforestation represents the second largest source of carbon emissions globally, reduces biodiversity and ecosystem services, and ... -
UAV remote sensing for the spatial differentiated assessment of plant traits based on multispectral images
(2023-01-09)Rising global temperatures, carbon dioxide (CO<sub>2</sub>) concentration, and the occurrence of extreme weather events are constantly changing the environmental conditions for crop productivity. Identifying climate-adapted ... -
Health and Welfare Implications of Climate Variability: Evidence from Rural Uganda
(2022-12-20)Uganda has been highly affected by extreme weather events and climate change in the recent years. Weather-related disasters could potentially affect health outcomes directly, or indirectly through its deleterious effects ... -
Heavy metal contamination in urban agriculture and human health risk in Yaoundé, Cameroon
(2022-12-14)Heavy metals are ubiquitous in the environment. The sources of heavy metals are both natural and anthropogenic activities. Urban growth, coupled with increasing demand for vegetables, has led to the utilization of lowlands ... -
Functional characterization of the maize (Zea mays L.) lateral rootless 1 gene
(2022-12-14)All root types form lateral roots. They are critical for efficient water and nutrient uptake by increasing the absorbing surface of the root system. In the maize differentiation zone, pericycle and endodermis cells adjacent ... -
Soviet tractors vs. oxen: agroecology, agricultural policies and political discourse in Cuba
(2022-12-07)After the collapse of the socialist bloc in the late 1980s and early 1990s, the Cuban government was forced to forsake its plans to develop a modern agricultural sector, highly dependent on the intensive use of imported ... -
Influence of dietary concentrations of L-histidine, alone or in interaction with β-alanine, on breast meat quality and metabolic status of modern, fast-growing broiler chickens
(2022-12-06)An increasing demand for poultry meat resulted in optimization of broiler chicken’s genetic towards high growth-rates and breast yield in the last decades. This breeding standard led to increased quality problems in breast ... -
Genetic analysis of drought stress adaptation in bread wheat diversity
(2022-12-06)The accumulations of proline (Pro) and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) are the typical response of plant against drought stress, therefore genetic analysis of these responses are crucial to establishing new ... -
Options to improve irrigation efficiency and productivity under rotational delivery schedule, a bottom-up approach applied at canal irrigation scheme in Pakistan
(2022-12-06)In Punjab, Pakistan, the Warabandi principle guides the distribution of surface water over a network of canals providing farmers with limited water in proportion to land size in a fixed 7-days rotation. Current problems ... -
Entwicklung eines Verfahrens zur dualen Anwendung von TrueColor-Sensoren bei der Pflanzendiskriminierung sowie Stickstoff-Düngung
(2022-12-06)Nicht erst seit dem Beschluss der Europäischen Union zur Umsetzung der Green Deal-Strategie ist die Reduktion von Pflanzenschutzmitteln und Mineraldüngern bei gleichzeitiger Versorgungssicherheit mit Lebensmitteln eine ... -

(2022-12-06)Die Gesundheit der Nutztiere, deren Lebensbedingungen und ihr Wohlergehen während der Aufzucht und Haltung gewinnen politisch wie auch gesellschaftlich immer mehr an Bedeutung und werden zwingende Qualitätsmerkmale tierischer ... -
Einsporisolate des Erregers des Asiatischen Sojabohnenrostes (Phakopsora pachyrhizi) zur Charakterisierung der Resistenz gegenüber Demethylierungsinhibitoren
(2022-11-28)Der pflanzenpathogene Pilz <em>Phakopsora pachyrhizi</em> verursacht den Asiatischen Sojabohnenrost (ASR) und stellt insbesondere in Südamerika eine große wirtschaftliche Bedrohung dar. Hier wurden nach erstmaligem Auftreten ... -
Genetic variations in root architecture traits for water and nitrogen use efficiency in wheat and barley
(2022-11-24)The soil edaphic resources such as water and nitrogen are essential for crop production because they are required by plants for proper growth and tissue development. The global crop production is vulnerable due to rapid ... -
Aspirations, shocks, and rural poverty
(2022-11-22)Poverty remains a persistent problem in many parts of the world, especially in sub-Saharan Africa (SSA). In this region, poverty is particularly prevalent in rural areas. Further exacerbating the high levels of poverty is ... -
Consistently closing global and regional sea level budgets
(2022-11-17)Nowadays, human-induced climate change is the major driver of global and regional sea level change threatening the well-being and livelihoods of hundreds of millions of people living close to the coast. Consequently, ... -
Phenotypic analysis of different Silphium perfoliatum L. accessions and evaluation as a renewable resource for material use
(2022-11-16)Cup plant (<em>Silphium perfoliatum</em> L.) is a promising alternative to silage maize as an energy crop for biogas production and a potential raw material for the industry. This non-food perennial from the US possesses ... -
Effect of blossom thinning on apple quality with conventional methods and study on laser application for selective thinning
(2022-09-27)Crop-load regulation by blossom thinning has an important role to improve the fruit quality and mitigate an alternate bearing on apple fruit production. This method aims to reduce excessive flowers to regulate the final ... -
