The quantitative relationship between size and reproductive output is a central aspect of a
plant's strategy: the conversion of growth into fitness. As plant allocation is allometric in the …

This review focuses on the mechanisms determining yield in maize, sunflower and soybean,
the three major summer crops of the Argentinean Pampas. Emphasis is given to the capture …

Nonlinear regression models are important tools because many crop and soil processes are
better represented by nonlinear than linear models. Fitting nonlinear models is not a single …

Seed number, the main yield component of cereals and oil‐seed species, strongly depends
on the physiological status of the crop during a critical period for seed set. Using a …

In maize (Zea mays L.), the negative effects of increased stand densities on final kernel
weight (KW) are attributed to reductions in the effective grain‐filling period, and not in kernel …

We investigated the response of maize kernel number to plant density in four hybrids
released in Argentina between 1965 and 1993. Assuming kernel number is the main yield …

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 …

Context Quantifying historical changes in maize harvest index (HI), the fraction of above-
ground biomass allocated to grain yield, can enhance our ability to explain grain yield trends …

Maize (Zea mays L.) grain yield responds greatly to plant density (D). However, the hybrid–
plant density interaction usually found is not well understood. The objective of this work was …

Modern maize (Zea mays L.) hybrids are generally regarded as strongly population
dependent because maximum grain yields (GYs) per area are achieved primarily in high …
