Abstract

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

Conclusions
