Other claims from this paper (9)
- Intervention effect Foliar IAA and/or IBA significantly reduced the incidence of downy mildew or purple blotch in field-grown onion compared with the control.
- Intervention effect Selenium and potassium hydrogen carbonate affected the incidence of both onion diseases.
- Intervention effect IAA at 400 ppm increased onion bulb yield by 93.5 and 53.3% over the control in the 2010 and 2011 growing seasons.
- Intervention effect Selenium at 50 ppm increased onion yield by 85.5 and 45.3% over the control.
- Intervention effect The tested treatments increased phenolic compounds in onion compared with the control.
- Intervention effect IBA gave the highest increment in phenolic compounds among the treatments.
- Intervention effect The highest increment with IBA was also recorded in total sugars.
- Intervention effect KHCO3 gave the least increase in total sugars compared with the control.
- Intervention effect Galben-Mancozeb was more effective than the other treatments in reducing both onion diseases.
