(2007-02-07)In the context of partially overstressed financial budgets for the acreage payment support in organic farming a more efficient support scheme seems to be necessary in the future. The political ... -
Multitrophic interaction of co-inoculated endophyte entomopathogenic fungi
(2022-07-11)The application of entomopathogenic fungi (EPF) as biocontrol agents of insect herbivores is constrained by their limited efficacy due to high sensitivity to UV-light radiation, water leaching, and fungicide application. ... -
Multitrophic plant insect interactions in dependence of belowground processes
(2005-06-03)Most ecologists acknowledge that plants are subject to complex interactions between both below- and aboveground dwelling animals. However, these complex interactions are seldomly investigated ... -
Multivariate analysis and artificial neural network approaches of near infrared spectroscopic data for non-destructive quality attributes prediction of Mango (Mangifera indica L.)
(2014-03-07)Mango is one of the most important and popular tropical fruits for people around the world due to its taste, appearance and excellent overall nutritional source from which lead to a heavy demand in world fruit market. With ... -
Mycorrhization and Warming Modulate Soil Organic Matter Stability
(2021-06-24)Soil organic matter (SOM) is the primary source of plant-available nutrients, as well as a substantial carbon (C) reservoir in terrestrial ecosystems. Maintenance of SOM levels is therefore critical for ecosystem sustainability. ... -
Mykotoxine und Kindergesundheit
(2014-03-20)Mycotoxins are naturally occurring mould toxins produced by fungi that often infect the crop in the field. One of the most frequently detected mycotoxin in cereals is deoxynivalenol (DON). In the European Union, mainly ... -
Nach dem Hochwasser ist vor dem Hochwasser: Eine Analyse zur Rationalität politischer Entscheidungsprozesse
(2014-10-29)How to assess Disaster Responds on Flood Events during the 20th Century – a conceptional framework and its application in Vietnam and Germany A comparison of disaster responds on flood events during the late 20th century ... -
Eine nachhaltige Entwicklung der intensiven Veredelung in Nordwestdeutschland: betriebliche Herausforderungen und Lösungsansätze der Primärproduktion in der Region
(2013-11-11)Livestock farming in northwestern Germany currently finds itself in a sensitive dilemma between economic needs – posed by international structural changes in livestock farming to competitiveness – and today’s development ... -
NACHHALTIGE NUTZUNG VON ERNEUERBAREN ENERGIEN – UNTERNEHMERISCHES INVESTITIONSVERHALTEN UND VERTRAGSGESTALTUNG
(2012-05-29)The conversion to renewable energy sources contains a number of challenges. This work focuses on selected questions from the two subject areas: • Entrepreneurial investment behavior concerning biogas plants and • Contracts ... -
Nachhaltigkeitsherausforderungen und Kommunikationsstrategien im Transformationsprozess Landwirtschaft
(2024-01-30)This dissertation, which focuses on sustainability work and sustainability communication in the field of agriculture, seeks to provide contributions on how German agriculture can position itself more sustainably and how ... -
Nahinfrarotspektroskopische Erfassung und Charakterisierung der nutritiven und fermentativen Qualität von Grassilage im ungetrockneten Zustand
(2008-02-26)Grassland and forage crop farms are faced with the challenge of cost-efficient production of farm-produces feed for the ruminant feeding. The objective of this work is to reach a time and cost reduction through the use ... -
Nahrungsökologie des invasiven Maisschädlings Diabrotica virgifera virgifera LeConte in Europa
(2003-09-15)The nutritional ecology of the invasive maize pest Diabrotica virgifera virgifera LeConte (Chrysomelidae, Galerucinae) was studied with regard to larval and adult food use and performance ... -
Die Neigung zu Schwarzfleckigkeit bei Kartoffeln (Solanum tuberosum) unter besonderer Berücksichtigung der Knollenphysiologie
(2009-10-21)Mechanical impact caused by harvesting and handling operations enhanced the susceptibility towards blackspot of potato tubers. Blackspot reduced the internal quality of potato tubers, which ... -
Neue Genpools aus resynthetisiertem Raps (Brassica napus L.) für die Hybridzüchtung
(2002-10-18)The small genetic basis of oilseed rape limits the prospects of hybrid breeding because the utilization of heterosis requires complementing genepools. In contrast to maize such gene pools ... -
