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 ...

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 morphology, mass, and grain yield as affected by early-season red: far-red light environments
The spatial arrangement among plants affects both vegetative and reproductive meristem development. More axillary meristems develop at lower plant densities, which are associated with relatively high red:far-red light ratios (R:FRs; 645:735 nm). However, little is known about the effect of R:FR on corn (Zea mays L.) productivity. We conducted field research to determine the effect of early-season ...

Yield Data Errors Today, Yield Costs Tomorrow
Regardless of whether your yield data comes from your combine, grain cart, or from truck scales, each source has shortcomings that will not only influence your farm decisions but may also have a negative financial impact. This harvest growers will spend significant time and money chasing down accurate yield data from combine yield monitors, grain carts and/or truck scale tickets. Each of these ...
