Interests and experience

modelling of yield and quality of forage crops, forage maize quality, forage crop rotations, plant physiology, analysis of virulence and resistance data in plant pathology.

Current research area

• development of a model for harvest time prediction of forage maize, in cooperation with the German Maize Comitee (DMK) and Institute of Crop and Grassland Science of the Federal Agricultural Research Centre (FAL)
• modelling forage quality of maize, cereals grown for whole crop, and grassland using FOPROQ
• environmental impact on forage yield and quality
• implementation of a model for harvest time prediction of grassland in the federal states of Nordrhein-Westfalen and Bavaria [poster, pdf]
• critical crude protein content of forage maize
• forage production in crop rotation versus maize monoculture
• analysis of virulence and resistance data in plant pathology, [www.va-tipp.de]
