(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 ... -
New Aspects of Biological Control of Helicoverpa armigera in Organic Cotton Production
(2003-02-11)Cotton is one of the most important economic crops in Egypt. Egypt started organic cotton production in 1991 in order to meet the demands for organically grown cotton in countries of the ... -
New Strategies for the Detection of <i>Fusarium</i> Infection and Mycotoxin Contamination of Cereals and Maize
(2013-08-13)Fusarium diseases occur worldwide in important agricultural crops and lead to the reduction of yield, seed quality and contamination of food commodities with toxic secondary metabolites, so called mycotoxins. The ... -
Nitrate uptake, root exudation, and litter quality - crop plant effects on denitrification and its product stoichiometry
(2021-06-18)Agricultural soils are the largest anthropogenic source of nitrous oxide (N2O) – a potent greenhouse gas that is primarily originating from the microbial processes denitrification and nitrification. While denitrification ... -
Nitrogen efficiency in semi-dwarf and normal hybrids of oilseed rape
(2015-06-19)The cultivation of winter oilseed rape is characterized by high rates of nitrogen fertilization. This can cause large nitrogen surpluses after seed harvest of oilseed rape. Most of the rapeseed oil is used for the production ... -
Nitrogen Efficiency of Winter Oilseed Rape and its Prediction by Hyperspectral Canopy Reflectance and Electrical Capacitance
(2016-07-01)Oilseed rape is the third most important oil crop worldwide. Under many conditions it is characterised by relatively low nitrogen efficiency. In Germany a nitrogen supply of 240 kg N ha 1 is aimed at which derives from ... -
Nitrous oxide from fungal denitrification - Pure culture and soil studies using stable isotope and microbial inhibitor approaches
(2014-12-17)The trace gas nitrous oxide (N2O) contributes to climate change as well as to the depletion of the ozone layer in the stratosphere. Agricultural soils account for about 70% of the high anthropogenic N2O ... -
Nutrition transition in the Indian rural-urban interface
(2021-07-27)While economic growth in many low- and middle-income (LMICs) has led to the reduction of poverty and undernutrition, some of these LMICs are undergoing a simultaneous increase in overnutrition and micronutrient deficiency. ... -
