Role of Calcium in Onion/Garlic

  • 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.
  • Use calcium 4 kg/acre as a soil treatment.
