Other claims from this paper (10)
- Intervention effect Nitrogen fertilization greatly increased seed yield under ample irrigation.
- Intervention effect Nitrogen fertilization had a lesser yield effect under moderate irrigation.
- Intervention effect Nitrogen fertilization had no yield effect under severely restricted irrigation.
- Intervention effect Aboveground total nitrogen increased with fertilization rate.
- Observation Aboveground total nitrogen doubled from first bloom to maturity at all nitrogen rates.
- Association Nitrogen recovery percentage decreased as applied nitrogen rate increased.
- Intervention effect Nitrogen fertilization increased seed yield with more tertiary heads and heavier secondary and tertiary heads.
- Intervention effect Nitrogen fertilization increased weight per secondary and tertiary head.
- Mechanism Greater secondary head weight resulted from greater weight per seed.
- Mechanism Greater tertiary head weight resulted from more seeds per head.
