e0“Dry matter yields, total plant N content, mean rate of N uptake per unit root weight, and the number of leaves expanded after imposition of solution osmotic potential treatments were decreased significantly by decreases in N supply and solution osmotic potential in the continuous water stress regime.”

Other claims from this paper (4)
- Intervention effect Lower osmotic potential did not change nitrogen concentrations in expanded leaves or shoots during continuous stress.
- Intervention effect Lower osmotic potential increased root and stem plus immature-leaf nitrogen concentrations during continuous stress.
- Intervention effect Relieved stress increased dry matter, leaf expansion, nitrogen content, nitrogen concentration, and nitrogen uptake rate relative to continuous stress.
- Association Leaf nitrogen concentration versus relative shoot yield relationships were non-asymptotic in all three index leaves, preventing critical nitrogen estimates.
