1. Tillage and Nitrogen Application Methodology Affects Corn Grain YieldMore efficient use of fertilizer nitrogen (N) is essential for improved yields and environmental stewardship. While university N recommendations for corn are based on observations typically made in conventional tillage systems, few universities have established research to evaluate if N recommendations should be different for alternative tillage systems. Generally spealung, no-till or minimum tillage systems have been identified as needing additional N to compensate for microbial immobilization of... |
2. NUE in Practice: Will N-efficient Corn Hybrids Sell?Efficient use of nitrogen (N) fertilizer is becomi ng increasingly important in corn production due to rising N fertilizer prices and growing concer ns about N contamination of ground and surface waters. Seed companies are also beginning to develop hybrids with N use efficiency (NUE) improved through trait introduction. The introduc tion of such hybrids will bring new questions about the value of higher NUE, and about risk ma nagement associated with decreasing, or not increasing, N use rates as... |
