A simulation approach for evaluating maize yield potential in different environments

What is yield potential? To achieve yield potential of an environment: Why yield potential important? Objectives: Nebraska (NE): To estimate yield potential across NE requires: How to estimate yield potential across NE? Choice of model: Hybrid-Maize Simulation of best yields under current practices Current practices: best yields Current practices: variation of best yields To achieving full yield potential: Optimal management: gain in season length Optimal management: gain in yield Optimal management: temporal (mean=14 y) variation of yields Conclusion
