Seasonal N Uptake
Nitrogen uptake of rice determined by harvesting the
aboveground biomass at different times during the growing
season.
Rice took up little N until tillering. Most N was taken up
between tillering and flowering (Linquist et al., 2006).
Nitrogen Partitioning
At maturity, approximately 70% of the aboveground N was in the
grains, while 30% was in the straw (Linquist et al., 2006).
Nitrogen Removed at Harvest
