Other claims from this paper (14)
- Observation At both sites under N0, soil alkali hydrolyzable nitrogen first declined then rose with development.
- Observation Under the other four treatments, soil alkali hydrolyzable nitrogen fell, rose after topdressing, fell again, then recovered after boll opening.
- Observation Available phosphorus at both sites initially declined and later increased.
- Observation Available potassium at both sites initially declined and later increased.
- Association Available nutrients declined with soil depth to 60 cm.
- Association At Nanjing under N1 to N4, alkali hydrolyzable nitrogen declined with horizontal distance from cotton.
- Association At Nanjing under N1 to N4, available phosphorus declined with horizontal distance from cotton.
- Observation N0 showed no clear horizontal variation.
- Association Nanjing showed greater spatiotemporal variation in alkali hydrolyzable nitrogen than Anyang.
- Association Anyang showed greater spatiotemporal variation in available phosphorus than Nanjing.
- Association Available potassium declined with distance at 0 to 60 cm in Nanjing and 20 to 60 cm in Anyang.
- Association At 0 to 20 cm in Anyang, available potassium showed the opposite distance trend.
- Intervention effect At Nanjing, 240 kg hm-2 N gave the highest lint yield and favorable yield components and fiber traits.
- Recommendation Fertilizer rates should be set by nutrient variation during flowering and boll stage in each ecological region.
