Other claims from this paper (16)
- Intervention effect Cotton biomass, N uptake and yield increased as irrigation amount increased.
- Intervention effect Cotton biomass, N uptake and yield increased as N amount increased.
- Intervention effect Cotton biomass, N uptake and yield were significantly less with saline water (SW) than with fresh water (FW) and brackish water (BW).
- Intervention effect Plant 15N recovery rates were greater in the I540 irrigation treatments than in the I405 treatments.
- Intervention effect Plant 15N recovery rates were greater in the N360 treatments than in the N240 treatments.
- Intervention effect Plant 15N recovery rates in brackish water (BW) were 7.98% greater than in fresh water (FW).
- Intervention effect Plant 15N recovery rates in brackish water (BW) were 30.01% greater than in saline water (SW).
- Intervention effect Residual soil 15N increased as N fertilizer amount increased.
- Intervention effect Residual soil 15N in brackish water (BW) treatments was 6.02% greater than in fresh water (FW).
- Intervention effect Residual soil 15N in saline water (SW) treatments was 21.44% greater than in fresh water (FW).
- Intervention effect Total 15N recovery was significantly greater in brackish water (BW) than in fresh water (FW) and saline water (SW).
- Intervention effect 15N leaching losses increased significantly with increases in irrigation amount.
- Intervention effect 15N leaching losses increased significantly with increases in irrigation water salinity.
- Intervention effect 15N leaching losses increased significantly with increases in N rate.
- Intervention effect The authors suggest that, with appropriate amounts of irrigation water and N fertilizer, brackish irrigation water (4.61 dS/m) will not affect cotton growth, yield and N recovery.
- Intervention effect The authors conclude that saline irrigation water (EC > 8 dS/m) reduces cotton growth, yield and N use efficiency.
