Model-based approach to quantify production potentials of summer maize and spring maize in the north China plain
The North China Plain (NCP) belongs to the major maize (Zea mays L.) growing areas in China. Maize yields have increased steadily since the 1980s, but in recent years average yields have stabilized around 5000 kg ha–1. The objective of this study was to quantify the production potential of summer and spring maize in the NCP. For this purpose the CERES-Maize model was calibrated and validated. The ...

Corn response to competition: growth alteration vs. yield limiting factors
Competition mechanisms among adjacent plants are not well understood. This study compared corn growth and yield responses to water, N, and shade at 74,500 plants ha–1 (1x) with responses to water and N when planted at 149,000 plant ha–1. Plant biomass, leaf area, chlorophyll content, reflectance, and enzyme expression (transcriptome analysis) were measured at V-12. Grain and stover yields were ...
