Dr. Kovács born and raised in Hungary, where he grew up in a small town, in the country’s primary agricultural production area. Péter received his MSc degree in Agricultural Engineering at the Szent István University. He participated in a double degree program through the Erasmus student exchange program to earn his MSc degree in Geographical Information Management at Cranfield University in the United Kingdom.
Dr. Kovács participated in farm exchange program sponsored by the Hungarian Department of Agriculture and Rural Development. He has worked on a family farm in west central Minnesota, and witnessed the adaptation of the use of precision agriculture tools in crop production.

During his PhD studies at Purdue University he was also involved teaching labs for undergraduate courses, and was a graduate advisor for the Agronomy Club.
Currently, Péter is an Associate Editor for Agronomy Journal, and he is also actively involved in the reviewing process for several International Journals.

Dr. Kovács has joined SDSU in November 2016 with research focus on Precision Ag Cropping Systems.

Area(s) of Research

Goal of the research program to improve the production of crops relevant to South Dakota using precision agriculture techniques while keep environmental stewardship in focus. My research focus is to improve crop production and input (e.g. nutrient, seed, etc.) use efficiency through the understanding of genotype x environment x management practice interactions and incorporate precision ag and remote sensing techniques into crop management and (immediate or future) decision making process(es).
In addition, we address today’s agronomic challenges and evaluate upcoming production systems and resources.

Main areas of research:
Precision Agriculture
Cropping Systems
Plant Nutrition
Tillage Systems
Applied Crop Physiology

Students interested in graduate school in these areas contact me with your CV and Statement of Research Interest.
