Results From On-Farm Research Trials
Corn Yield Response to Nitrogen Fertilizer Rates
Field-scale trials have been conducted at seven of Purdue's outlying agricultural research stations plus many on-farm locations throughout the state. Since 2006, more than 200 such trials have been completed and the results from those trials have been compiled and summarized in the following crop research update.
