Seasonal N Uptake
Nitrogen uptake of barley grown at two fertilization rates determined by harvesting the aboveground biomass at different times during the growing season.
Barley took up little N until tillering. Most N was taken up between tillering and heading (adapted from Delogu et al., 1998; Jackson and Williams, 2006).
Nitrogen Partitioning
At maturity, approximately three fourths of the aboveground N of high yielding barley is in the grains, while about one fourth is in the straw (for references see Table 1).
Nitrogen Removed at Harvest
Barley yield and N removed at harvest. Since grain often accumulates more protein at higher fertilization rates, more N per ton of grain is removed when more N is applied.
