ABSTRACT

 

Ongoing increases in global population and expanding settlement areas
brought by this situation have an important results like decreasing farmlands.
Hence, it has great importance to increase the yield rates obtained from the
unit area. As well known, crop yield is mainly affected by nitrogen content of
soil and plant. Thus, in this study, it was aimed to investigate the nitrogen
content in a wheat cultivated field by the help of a HERMES crop model by using
some meteorological parameters collected from an experimental site in
Kırklareli City of the Thrace Region located in northwestern part of Turkey. In
this frame, possible effects of variations in meteorological parameters were simulated
using the model. Variations in nitrogen content were determined under
consideration of the winter wheat crop grown. Results were evaluated by means
of the analysis of both plant and soil nitrogen contents. 

 

Key words: Mineralization,
