1. Utilizing the Greenseeker to Evaluate Spring Wheat Growth and Yield

There is currently little information on the use of existing sensor-based technologies for in- season application of nitrogen (N) to spring wheat (Triticttm aestivztm L.) in the northern Great Plains. Over the past decade researchers in the southern Great Plains have developed the Greenseeker as a tool for on-the-go N application to winter wheat. Field experiments were established in Brookings and Gettysburg, SD to evaluate the Greenseeker Hand Held optical sensor (NTech Industries, Ukiah, CA) for...
