Prof. Dr. Mehmet Senbayram

Prof. Dr. Mehmet Senbayram held the junior professorship at the IAPN till end of July 2015 and supervised a junior research group.


Professor Senbayram holds a Ph.D. degree from the Christian-Albrechts-University of Kiel. His Ph.D. study focused on measurement and modeling of nitrous oxide emissions and carbon balances of soils during production of bio-energy crops. His previous research focused on studying plant physiology (role of plant nutrients on water use efficiency of field crops) and microbial process physiology (product stoichiometry of nitrification, denitrification).


Researching abiotic stress tolerance-plant nutrients interaction

The former staff member Professor Senbayram at IAPN focused on drought tolerance-plant nutrients interaction with emphasis on increasing water use efficiency of arable crops by nutrient management. "Water shortage is one of the major stress factors that inhibit plant growth hence negatively effecting food security. The research at IAPN focuses the role of key plant nutrients on the mechanisms and processes that control drought stress tolerance and water use efficiency of crop plants. Optimal nutrient management plays a key role on safeguarding and improving agricultural production in changing climate", said Professor Senbayram, who used new analytical techniques (multi-sensing approaches), which will allow to identify problems and develop solutions on time.


Mehmet Senbayram was born in Turkey. He studied agricultural sciences at the Ege University in Turkey and at the Christian-Albrechts-University of Kiel in Germany. After his Ph.D. study, he worked several years in applied agricultural sciences at the Hanninghof Research Station in Dülmen, Germany.
