The improved grain yield per unit area of modern maize (Zea mays L.) hybrids is due to the
increased optimum plant population rather than the improved grain yield per plant. Traits …

Global weather changes compel agriculture to be adequately productive under diverse and
marginal conditions. In maize, modern hybrids fail to meet this requirement. Although …

Density-dependent maize hybrids have a number of disadvantages such as the strong
dependence of the crop yield on the seeding rate, the high hybrid by density interaction, and …

This paper explores the genetic basis of high and stable crop yield, and delineates the
conditions that provide the link between genotypic and phenotypic superiority and …

Competition between crop plants, due to resource limitation, is at the root of a considerable
yield limitation, a major problem that future agriculture is faced with. Due to inter-plant …

Plant yield efficiency (PYE) reflects the ability of the single‐plant to respond to additional
inputs and is fully expressed at the nil‐competition regime (an ultra‐low density to preclude …

Natural selection favors the competitive ideotype, enabling native plants to survive in the
face of intense competition. The productive ideotype is the goal of artificial selection to …

The ability of agriculture to adapt to environmental changes and to address main issues of
food quality and environment protection is a fundamental factor in achieving sustainability …

Improvement for maize drought tolerance has always been a significant objective for
breeders and plant physiologists. Nowadays, climate change sets new challenges to major …
