Cotton Nitrogen Uptake and Partitioning

The Fertilization guidelines can also be found on the UC Davis Nutrient Management website .

Seasonal N Uptake

Season N Uptake Curve Graph

Nitrogen uptake of cotton grown in Fresno and Kings County was determined by harvesting the aboveground biomass at different times during cotton development. Cotton plants took up little N until they reached the early square stage. Most N was taken up between the early square and peak bloom stage [2].

Nitrogen Partitioning

Nitrogen partitioning pie chart

Measured immediately before defoliation, more than half of the aboveground N of Accala cotton was in the seeds. Nitrogen in the fiber and burs accounted for about 15% [2].

Nitrogen Removed at Harvest

Nitrogen removed with harvested corron lint and seed. The overall average is weighted for the number of observations in each trial. More information can be found here [3].

Location Years Removal (lbs N/ton lint and seed) Source

Israel 1980-85 47.4 39.5 - 54.5 [4]
Greece 2008-09 44.8 43 - 46.4 [6]
Syria 2011 32.6 30.5 - 35.1 [5]
Weighted Average 43.7 23.3 - 63.2
