1. Nitrogen Timing Fertilization Strategies for Winter Wheat in WisconsinEconomically optimum winter wheat (Triticum aestivum L.) production relies on effective N application rate and timing. Previous research in Wisconsin indicates a need to better understand winter wheat response to N rate and application timing for growing conditions specific to the state. This study evaluated the effect of N application timing on yield, economic optimum N rate (EONR), agronomic N use efficiency (NUE), and profitability. A three-year study was conducted at three locations... J.D. Jones, C.A. Laboski, T.W. Andraski |
2. Effects of Soil Phosphorus and Potassium Levels on Corn Yield Response to Nitrogen Fertilization, Nitrogen Use Efficiency, and ProfitabilityAnnual investment in nitrogen (N) fertilizer for corn production represents a significant portion of annual input costs. Yield response to N fertilization is affected by soil N supply, crop N demand, and interacting factors that affect crop N use, such as phosphorus (P) and potassium (K) supply. To investigate the effects of soil-test P and K levels on corn yield response to N fertilizer, a four-year study was conducted at two southern Wisconsin sites. Soil-test P and K were maintained at low,... J.D. Jones, C.A. Laboksi, F.J. Arriaga |
