Other claims from this paper (8)
- Recommendation A low to moderate nitrogen rate after litter cessation optimized leaf area, nitrogen removal and lint yield.
- Intervention effect The management practice reduced postharvest nitrate in the top 30 cm by about 61%.
- Intervention effect Nitrogen removal did not differ between residual litter plus 84 kg N ha−1 and fertilizer-only treatments.
- Intervention effect Nitrogen removal was much lower under residual litter alone.
- Intervention effect In 2014, litter plus fertilizer raised lint yield 10% over fertilizer alone.
- Intervention effect In 2015, litter plus fertilizer raised lint yield 5% over fertilizer alone.
- Intervention effect In 2016, litter plus fertilizer raised lint yield 20% over fertilizer alone.
- Recommendation The authors conclude that side dressing 56 or 84 kg ha−1 nitrogen can meet cotton nitrogen requirements after litter cessation.
