Calcium is an important nutrient in onion/garlic and has a key role to play in crop yield and quality.
Calcium promotes the enhancement of root establishment and elongation of cells resulting in increased plant height. It also improves the tolerance of disease and low temperatures.
Participates in metabolic processes of other nutrients uptake. Promotes proper plant cell elongation.
Participates in enzymatic and hormonal processes. Helps in protecting the plant against heat stress
Helps in protecting the plant against diseases – numerous fungi and bacteria secrete enzymes which impair plant cell walls. Stronger Cell walls, induced by calcium, can avoid the invasion.
Increased bulb quality.
Thus the main function of calcium in onion/garlic is to keep the crop free from disease and increase the yield, quality, and storage of onion/garlic.
