Other claims from this paper (7)
- Intervention effect Deficit irrigation significantly reduced sunflower plant growth parameters (canopy coverage and biomass, not root length density) compared with full irrigation.
- Observation The pre-flowering stage was the critical stage for sunflower response to deficit irrigation.
- Observation DI-60 at vegetative and pre-flowering stages gave a seed yield of 2.18 t ha−1 at normal soil.
- Observation DI-60 at vegetative and pre-flowering stages gave a seed yield of 2.53 t ha−1 at saline soil.
- Observation DI-60 at vegetative and pre-flowering stages saved 68.15% water at normal soil.
- Observation DI-60 at vegetative and pre-flowering stages saved 54.75% water at saline soil.
- Intervention effect The T6 treatment gave the highest water productivity, irrigation water productivity and net financial return among the sunflower irrigation treatments.
