Rice Nitrogen Uptake and Partitioning
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 .
At maturity, approximately 70% of the aboveground N was in the grains, while 30% was in the straw .
Nitrogen Removed at Harvest
