Abstract
As explained last week, fertilisation is used to stimulate growth of the onion plant, then nitrogen is reduced to encourage early maturity. This is a good time to apply potash too if your soil analysis shows this is at a marginal level - it will enhance onion quality. Withholding water will also speed up bulb maturity. Do so gradually so as not to shock the plant and cause it harm. The leaves will take on a dull, bluish appearance; this is not a problem. What you don't want is wilting; this is an indication of too much stress. These strategies will encourage the plant to divert energy from the leaves to the bulb. When the day-length is right, bulbing speeds up and the neck of the plant becomes soft and weak, causing the leaves to fall over. This is where some farmers make a mistake. In an effort to help nature along, they run a roller through the land to force the remaining onions over.
