Improving Onion Health

Fertilizer programs starting early during establishment and vegetative growth are needed to ensure nutrients don’t limit onion bulb quality. A healthy crop is one that is free from pests and diseases, and at the same time meets quality and yield demands. Many factors influencing the health of onions crops are within control of the growers.

Onions are also very susceptible to foliar diseases and bulb rots. Bacterial related diseases reduce bulb quality. Thus, soil, fertilizers and water management practices are essential to control, for example, rot problems. A balanced nutrition program can help grow a strong and healthy crop, protecting it from pests and disease susceptibility, thus increasing shelf life and quality of the product.
