Other claims from this paper (15)
- Intervention effect Increasing irrigation and nitrogen significantly increased leaf area index, growth rate, yield attributes and grain yield.
- Observation Maximum LAI and growth rate occurred with the highest irrigation and nitrogen levels at 73–88 days.
- Association LAI estimates with biological yield were 92% in 2002–03.
- Association LAI estimates with biological yield were 38% in 2003–04.
- Intervention effect Four irrigations raised mean grain yield 47% in 2002–03 versus one irrigation.
- Intervention effect Three irrigations raised mean grain yield 23% in 2002–03.
- Intervention effect Two irrigations raised mean grain yield 9% in 2002–03.
- Intervention effect Four irrigations raised mean grain yield 91% in 2003–04.
- Intervention effect Three irrigations raised mean grain yield 84% in 2003–04.
- Intervention effect Two irrigations raised mean grain yield 23% in 2003–04.
- Intervention effect Water deficit reduced grains per spike by an average 36%.
- Intervention effect Water use efficiency was 41% higher under one irrigation than four.
- Intervention effect At all irrigation levels, 150 kg nitrogen gave significantly higher water use efficiency.
- Association Water use efficiency decreased as irrigation number increased.
- Intervention effect Nitrogen application significantly improved water use efficiency.
