Onions thrive best when temperatures are cool during early development and then warmer and sunny during maturity. Nutritional programs containing soluble calcium can help to protect crops against chilling injury, which can lead to cell breakdown.
Calcium protects onions against chilling injury
Calcium is a key nutrient that helps protect against chilling injury, which can lead to cell breakdown. This can be valuable in stores where there is poor temperature control.
Calcium also helps to reduce the effect of salt stress on onions.
