Field trials with Zea mays hybrid XL66 showed that nitrogen supply during spikelet differentiation affected grain number markedly. Nitrogen supply during grain filling had a small but significant effect on grain filling and an effect on the rate of nitrogen entry to the grain, causing a 1.3-fold change in percentage grain nitrogen. Fertilizer management had most effect on yield: there was no evidence that shoot size controlled grain number or rate of grain growth.
