HEAR THIS! How you can produce bigger onions for export

Bigger onions for export, or for local market if there are those that need them.

Importers of onions from other countries usually want to buy onion bulbs that weigh about 600 grams each. So how can Philippine farmers produce such onion bulbs?

TIME YOUR PLANTING – Michael Caballes, former president of Allied Botanical Corporation, says there is a theory that bigger onion bulbs can be produced in areas of higher latitude (northern Luzon). Bulb formation which starts two months after transplanting should coincide with the coolest months of the year. This means that planting should be around November so that bulb formation will be in the cool months of January and February.

NUMBER OF LEAVES – Caballes adds that the number of leaves affects the size of the bulb. The more the leaves, the bigger the bulbs. Therefore, the growers should pay attention to the proper fertilization to promote leaf formation right from the start. This means also paying attention to distance of planting that will result in maximum leaf production.

FOR GOV’T RESEARCJERS – The suggestion is that government researchers should conduct research that will come up with a planting protocol based on scientific findings. This should include recommended good agricultural practices (GAP) that will ensure acceptance of locally-produced onions in the export market.
