Graduate Students Receive Awards at Agronomy, Crop and Soil Meeting

Three North Dakota State University Plant Sciences graduate students received awards during the annual joint meetings of the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America in Tampa, FL.

Three North Dakota State University Plant Sciences graduate students received awards during the annual joint meetings of the American Society of Agronomy (ASA), Crop Science Society of America (CSSA), and Soil Science Society of America (SSSA) in Tampa, FL, on October 22-25. Matthew Rellaford won first place for his presentation in the “Sensor-Based Nutrient Management” session, Nicholas Schimek won first place for his poster in the “Current Research for Advancing Precision Agriculture” session, and Nickolas Theisen was awarded the J. Fielding Reed Soil and Plant Sciences Scholarship. (see link to separate story).

Rellaford presented “Predicting Potential Grain Protein Content of Spring Wheat with in-Season Hand-Held Optical Sensors”. The goal of his research was to determine whether hand-held optical sensors can be used to predict Grain Protein Content (GPC) in spring wheat. The sensors give a reading called the Normalized Difference Vegetation Index (NDVI), which is used to gauge crop health. Rellaford looked at the relationship between NDVI at three plant growth stages and post-harvest GPC to determine whether there was a predictive relationship. The research was supported by the Minnesota Wheat Research and Promotion Council.

Schimek presented his poster, “Reliability of Predicting Spring Wheat Yield with DSSAT Using Early Season Weather Data”. He described his research using the Decision Support System for Agrotechnology Transfer (DSSAT) crop modeling software to determine how well the model could be adapted to predict spring wheat yield, how early in the growing season the model could accurately simulate end season yield, and the best strategy to use historic weather data to forecast weather for the remainder of the season.

Rellaford is from Columbus, Ohio and American Fork, Utah, and Schimek is from Deer River, Minnesota. They are advised by Joel Ransom, plant sciences professor and Extension agronomist.

Over 4000 agriculture, crop and soil professionals attended the ASA-CSSA-SSSA meetings. The annual meeting provides an opportunity to share and learn from the latest research and network with peers. For more information, see https://www.acsmeetings.org/.
