Other claims from this paper (11)
- Intervention effect Full irrigation increased mean absolute growth rate across the two legumes by 51% over no irrigation.
- Observation Fully irrigated chickpea had a growth rate of 18.6 g m day.
- Observation Fully irrigated lupin had a growth rate of 23.0 g m day.
- Intervention effect Fully irrigated crops yielded three times as much seed as unirrigated crops.
- Observation Under full irrigation, chickpea seed yield was 326 g m.
- Observation Under full irrigation, lupin seed yield was 581 g m.
- Intervention effect Double irrigation reduced seed yield of the two legumes by 45% versus full irrigation.
- Intervention effect Full irrigation increased intercepted radiation by 28% in chickpea.
- Intervention effect Full irrigation increased intercepted radiation by 33% in lupin.
- Mechanism The authors attribute increased seed yield to increased radiation interception.
- Recommendation The authors recommend irrigating crops throughout growth to replace water deficit.
