As soybean yield continues to increase, it seems critical to know if there is a yield level at
which potential contribution of indigenous nitrogen (N) sources (N fixation and soil …

Soybean [Glycine max (L.) Merr.] seed composition and yield are a function of genetics (G),
environment (E), and management (M) practices, but contribution of each factor to seed …

Genetic progress is assessed to estimate its contribution to on‐farm yield increases and to
identify traits that have been improved over some period of time. Although Argentina is a …

Soybean [Glycine max (L.) Merr.] yield has increased during the past century; however, little
is understood about the morphological parameters that have contributed most to yield gain …

Few studies have investigated changes over time in nutrient uptake and yield, in addition to
the study of nutrient stoichiometry as a metric of nutrient limitations in soybean [Glycine max …

The USA accounts for 38 and 35% of global maize and soybean production, producing a
respective 320 and 84 Mt of these crops annually. More than 85% of those totals are …

The largest reported soybean grain yield is approximately three-fold more than the highest
reported US average yield. An understanding of yield determination is needed to identify …

Summary Soybean [Glycine max (L.) Merr.] yield improvement arises from continual
producer adoption of genetic technology—the annual releases of new cultivars that express …

Soybean is one of the most common grain crops worldwide, representing an important
protein and oil source. Although genetic variability in the chemical composition of grains is …
