Other claims from this paper (16)
- Intervention effect Cotton biomass, nitrogen uptake and yield increased with irrigation amount.
- Intervention effect Cotton biomass, nitrogen uptake and yield increased with nitrogen amount.
- Intervention effect Cotton biomass, nitrogen uptake and yield were significantly lower with saline water than with fresh or brackish water.
- Intervention effect Plant ¹⁵N recovery was greater at I540 than I405.
- Intervention effect Plant ¹⁵N recovery was greater at N360 than N240.
- Intervention effect Plant ¹⁵N recovery in brackish water was 7.98% greater than in fresh water.
- Intervention effect Plant ¹⁵N recovery in brackish water was 30.01% greater than in saline water.
- Intervention effect Residual soil ¹⁵N increased with nitrogen fertilizer amount.
- Intervention effect Residual soil ¹⁵N declined with irrigation amount.
- Intervention effect Residual soil ¹⁵N was 6.02% greater with brackish than fresh water.
- Intervention effect Residual soil ¹⁵N was 21.44% greater with saline than fresh water.
- Intervention effect Total ¹⁵N recovery was significantly greater in brackish than fresh and saline water.
- Intervention effect Nitrogen leaching losses increased significantly with irrigation water salinity.
- Intervention effect Nitrogen leaching losses increased significantly with nitrogen rate.
- Recommendation With appropriate irrigation and fertilizer amounts, brackish water at 4.61 dS/m was judged not to affect cotton growth, yield or N recovery.
- Recommendation Saline irrigation water above 8 dS/m was judged to reduce cotton growth, yield and N use efficiency.
