e0“A pot experiment was conducted”
e1“yield of rice under two cadmium (Cd) levels (0 and 100 mg Cd kg−1 soil)”
e2“Cadmium addition significantly reduced photosynthetic rate, and the reduction varied with N fertilizer form, with ammonium (NH4 +)-N and urea treated plants having more reduction”

Other claims from this paper (13)
- Intervention effect Cadmium addition significantly reduced the photosynthetic rate of rice.
- Intervention effect Nitrogen form had a distinct effect on the SPAD value of rice, dependent on Cd level and growth stage.
- Intervention effect Cadmium stress significantly reduced the flag leaf area of rice.
- Intervention effect Under Cd stress, only organic N supply caused a reduction in the second leaf of rice.
- Intervention effect Ammonium-N treated rice plants had the highest plant height among the four N forms.
- Intervention effect Nitrate-treated rice plants had the lowest plant height among the four N forms.
- Intervention effect Cadmium stress significantly reduced grains per panicle and total plant weight of rice.
- Intervention effect Organic N treatment gave a larger reduction in grains per panicle and total plant weight of Cd-stressed rice.
- Intervention effect In Cd-stressed rice, NH4 +-N treated plants had the highest N concentration.
- Intervention effect In Cd-stressed rice, NH4 +-N treated plants had the lowest Cd concentration.
- Intervention effect In Cd-stressed rice, NO3 −-treated plants had the lowest N concentration.
- Intervention effect In Cd-stressed rice, NO3 −-treated plants had the highest Cd uptake.
- Association The inhibition of rice growth and yield formation by Cd stress is closely related to N fertilizer form.
