Untersuchung des Einflusses von Verschiedenen Düngermengen und –typen (am DDV Dikopshof) ODER von Weizen-Ackerbohne Mischanbau (CKA) auf das Pflanzenwachstum sowie die Stickstoffverluste

The student will sample Persian clover and winter rye plants on several dates in spring and summer 2024 in 6 treatments and measure about biweekly laughing gas (N2O) emissions in-situ. The student will be supported by student assistants. In the EU project IntercropVALUES, scientists aim to assess the crop performance and key ecosystem services (ES) of intercrops versus sole crops in various experiments located in and outside of Europe. One of the field trials is located at Campus Klein-Altendorf (University of Bonn). It is comprised of 14 treatments and tests sole crops (faba bean and two spring wheat cultivars) and the in-row mixture of both crops at different levels of mineral nitrogen (N) fertilization.

The student will sample in the solely and the mixed treatments of sprig-wheat and faba bean on several dates in spring and summer 2024 in 6 treatments and about biweekly measure N2O emissions in-situ. The student will be supported by student assistants.

This work will include a literature review, several field days at Dikopshof or CKA, some days in the lab (Campus Bonn) for processing of shoot samples and leaf area measurements
