Other claims from this paper (9)
- Intervention effect Soil applied biostimulants reduced the adverse impact of water deficit on onion relative to control.
- Observation Yeast extract produced the highest plant height, neck and bulb diameter, shoot and bulb fresh weight, and total yield in both seasons.
- Intervention effect With yeast extract at 80% ETc, the reduction relative to 100% ETc was 5.18% in the first season.
- Intervention effect With yeast extract at 80% ETc, the reduction relative to 100% ETc was 4.65% in the second season.
- Intervention effect Yeast extract at 80% ETc increased total yield by 16.37% over untreated plants at 100% ETc in the first season.
- Intervention effect Yeast extract at 80% ETc increased total yield by 16.03% over untreated plants at 100% ETc in the second season.
- Observation Irrigation at 80% ETc with yeast extract recorded the highest irrigation water use efficiency.
- Intervention effect Irrigation water use efficiency with yeast extract did not differ significantly from yeast extract plus potassium humate.
- Recommendation The authors conclude yeast extract could increase onion tolerance to deficit irrigation.
