Modern breeding informatics approaches to optimise breeding of rhizomania resistance in sugar beet (Beta vulgaris L.) and its genomic prediction
(2024-04-26)Rhizomania, a viral disease caused by the Beet necrotic yellow vein virus (BNYVV), is considered the most destructive disease in sugar beet (Beta vulgaris L.). Since no plant protection against rhizomania is currently ... -
Soil Multi-Meta-Omics: Unraveling microbial regulation at three post-genomic levels
(2024-04-19)Soil functions are key in all ecosystems globally. Specifically soils play a pivotal role in ecosystem biogeochemical cycles, sequestering but also mineralizing carbon (C), and in this context releasing nutrients from ... -
Evaluating a Collection of Agronomic Traits to Better Understand the Importance of Epistasis and Epistasis by Environment Interaction in Maize.
(2024-04-05)Maize, a key cereal crop, stands alongside wheat and rice in global importance. Its domestication from teosinte in southern Mexico 10,000 years ago marked a turning point in human agriculture. Over the centuries, maize has ... -
Analyzing Smallholder Farmers Performance - Farmer Typology, Technical Efficiency, Market participation, Policies and Management Practices Evidence from Limpopo Region of South Africa
(2024-02-22)Sub-Saharan Africa's population is projected to grow to almost double its population by mid- century, leading to more demand for food and agricultural products. As the main source of food and livelihood, the agricultural ... -
Die Digitalisierung der Milchwirtschaft: Gesellschaftliche Akzeptanz und Nutzungsbereitschaft unter Landwirten
(2024-02-02)The advancing process of digitalization, also known as the Fourth Industrial Revolution, has already exerted a multifaceted influence across various domains of life and is characterized as a megatrend of the 21st century. ... -
Challenges of the Farmland Market: Essays on the Tension between Financialization and Regulation
(2024-01-18)In the recent decades, the German farmland marked faced enormous price increases. Those price increases caused intensive research. Among others, three streams of thought were especially in focus: farmland price ... -
Quantitative effects of the abiotic factors temperature and day length on vernalization, flowering time and freezing tolerance of oilseed rape (Brassica napus L.).
(2024-01-11)Two important abiotic factors for plants are temperature and day length. Long day and short day are signals that can induce morphological and developmental changes like flower induction. So-called short day plants need a ... -
Objectives, management practices, and perspectives of small-scale private forest owners
(2024-01-11)Climate change and diverse societal demands ranging from resource use and recreation to biodiversity conservation are influencing forests today and have sparked an intensive debate about future forest management. One ... -
Analyse des Liquiditätsmanagements in landwirtschaftlichen Unternehmen am Beispiel von niedersächsischen Milchviehbetrieben
(2023-12-08)Dairy farms are increasingly exposed to volatile prices for both milk and input factors in milk pro- duction. Price fluctuations in the world market are more strongly reflected in the EU internal mar- ket than before due ... -
Investigation of the Regulatory Processes of Gene Expression in Animal and Plant Sciences
(2023-12-08)Transcriptional regulation of gene expression in higher organisms is fundamental for numerous biological processes. These processes are mainly controlled by a special class of regulatory proteins, the transcription factors ... -
Produktionsökonomische Analyse von Tierwohlmaßnahmen in typischen Milchviehbetrieben Nordwestdeutschlands
(2023-12-01)Farm animal husbandry is the most important sector of the German agriculture and food industry. With an overall share of 22 percent of the production value of agriculture, milk production is of particularly great economic ... -
Breeding for Improved Flavour of Fresh Market Tomatoes: Breeders' Sensory Test and Molecular Markers
(2023-12-01)Until recently, flavour was not a primary breeding target in tomatoes (Solanum lycopersicum L.). However, the poor flavour of tomatoes is a major cause of consumer complains. Flavour results from a complex interaction ... -
The effect of global change on multitrophic interactions of sugar beet
(2023-12-01)Global climate change models predict changes in rainfall patterns and rising sea levels, resulting in severe drought and soil salinity, which are already observed in many countries worldwide. Abiotic stressors such as ... -
Local and landscape threats to bee and wasp populations in agricultural landscapes
(2023-12-01)The transformation and intensified use of the agricultural landscape in central Germany in the past decades has led to the fragmentation and loss of semi-natural habitats, threatening biodiversity including insects. Bees ... -
