Determining to what degree seed weight differences are due to competition among seeds
for insufficient source is critical for the rational design of breeding and management …

Studies across different crops demonstrated that grain or seed number per unit area (GN m–
2) is the dominant yield component. Although grains or seeds derive from floret or flower …

The availability of water and nitrogen (N) to maize during its flowering stage affects the
growth of individual kernels. The present study reports the variability of maize kernel dry …

Maize (Zea mays L.) hybrids differ in their response to plant population density.
Enhancements in tolerance to crowding have been obtained around the world as the result …

Maize crop management involves decision making on several cultural practices aimed to
maximize grain yield, like plant population and row spacing. These practices affect the light …

Genetic gains in grain yield and related phenotypic attributes have been extensively
documented in maize (Zea mays L.), but the effect of breeding on the physiological …

Heat stress around flowering has negative effects on maize (Zea mays L.) grain yield. Most
research on this topic focused on the response of pollen viability and pollination constraints …

Improving the development of inferior grains is important for increasing maize yield under
high-density conditions. However, the effect of micronutrients, especially zinc (Zn), on the …

Reduced plant biomass and increased plant-to-plant variability are expected responses to
crowding in monocultures, but the underlying processes that control the onset of interplant …

Background and Aims There are three reasons for the increasing demand for crop models
that build the plant on the basis of architectural principles and organogenetic processes:(1) …
