Verbatim
e0“Field experiments were conducted to document the effects of N nutrition on photosynthesis, canopy growth, and yield of cotton (Gossypium hirsutum L.)”
e1“Nitrogen deficiency limited dry matter accumulation of leaves, stems and bolls”
e2“Total dry weight of N‐deficient plants was significantly reduced by 7% at 76 days after planting (DAP) and by over 18% at 118 DAP”
e3“Leaf area index (LAI) of N‐deficient canopies was significantly decreased at 76 DAP, with an LAI at 118 DAP of 2.5 versus 3.6 for N‐sufficient plants”

Other claims from this paper (8)
- Intervention effect N deficiency significantly reduced total dry weight of cotton by over 18% at 118 DAP.
- Intervention effect N deficiency significantly decreased leaf area index of cotton canopies at 76 DAP.
- Intervention effect Leaf area index of N-deficient cotton was lower at 118 DAP (2.5) than in N-sufficient plants (3.6).
- Intervention effect N deficiency decreased growth rates of cotton leaves at 5 days after leaf unfolding.
- Intervention effect N deficiency reduced individual leaf areas of cotton by more than 25% at leaf maturity.
- Intervention effect N deficiency did not affect photosynthesis, transpiration or stomatal conductance of upper-canopy cotton leaves.
- Intervention effect Whole-canopy photosynthesis per leaf area of N-deficient cotton increased because of better light distribution.
- Intervention effect Canopy photosynthetic rates per unit ground area of cotton were similar between N treatments.
