Theresa Piskackova

Doctor of Philosophy in Crop Science

Thesis:  Developing weed emergence and phenology predictive models

Advisor: Dr. Ramon Leon

Graduate Committee:
Dr. Chris Reberg-Horton, Dr. Katie Jennings, Dr. Rob Richardson

Research Summary:
In the agricultural industry, the goal is to be increasingly precise in what inputs are used, where, and at what time. For weed control, timing is especially important, but this is mostly left to the efficiency of a few people scouting hundreds of acres. Weed predictive modeling could reduce the need for scouting and increase the accuracy of weed management timing. My research focused on three prevalent weeds of agronomic crops in North Carolina. Over two years and multiple locations we were able to predict the timing of emergence and growth stages of Palmer amaranth, sicklepod, and wild radish. Additionally, we developed a method for quantifying emergence using digital images that will increase the ease of collecting data for further emergence models.

I plan to use my degree to:
The knowledge and experience I gained while working on this Ph.D. has helped me grow as a researcher and professional. I hope that I will be able to be a more effective teacher and communicator, a more thoughtful researcher, and I now have connections and a better understanding of agriculture in North Carolina.

What I enjoyed most about my experience in Crop and Soil Sciences at NC State was:
I enjoyed being a TA for two semesters. I wish I could have done more teaching. I participated in the Graduate School Teaching and Communication Certificate in the last two semesters of my program and it has been probably the best experience at NC State.  The workshops included a diverse group of people, and I was able to learn about different research and programs all over campus as well as get constructive feedback on my work and teaching strategies.

I really enjoyed the department seminars, especially when we brought in others such as for the Seeds of Change, Wernsman, and the Worsham series. The speeches themselves were important to see others research and ask questions, but I really enjoyed the discussion times that we schedule around them. Having lunch with the speakers has been extremely interesting. I always come away from these times with new ideas and motivation when I go back to my work.

While earning my degree, my greatest supporters were:
My advisor Dr. Ramon Leon and my husband Jan Piskacek.

Now that I have completed the program, I’m most looking forward to:
New adventures, challenges, and opportunities for growth.
