1. Assessment of Long-term Effects of Tillage and Nitrogen Management Practices on Irrigated Corn Yields and Nitrogen Use EfficienciesCorn grain yields and crop nitrogen uptake are affected by management factors such as tillage intensity and nitrogen rates. Additional data about the long-term effects of tillage and nitrogen rates on yields and nitrogen use efficiencies of irrigated corn are needed. We are presenting preliminary results from a 17-year study about the effects of these management practices on irrigated corn yields and nitrogen uptake in a Fort Collins clay loam soil at Colorado State University’s Agricultural...

2. Effects of Climate Change and Narrow Rows with Higher Plant Densities on Yields of Irrigated CornClimate change is significantly impacting agricultural systems worldwide, and although there are reports of these impacts contributing to higher yields in some regions, the general consensus is that there will be negative impacts on yields and soil quality across large regions. Management practices that can contribute to higher yields and adaptation to a changing climate will be important during the 21st century. This presentation will cover results from two manuscripts that are currently... J.A. Delgado, B. Floyd, R. D'adamo, A. Villacis, A.D. Brandt, A. Halvorson, C.E. Stewart, J. Alwang, S.
