f. Fertilization
The total amount of P and K and half of N is applied at planting time or a few weeks after
N is sidedressed at bulbing stage. For best results, the fertilizer should be applied in band
5-8 cm below the seeds.
g. Irrigation
Irrigate the field by flooding or overhead or both depending on the source of irrigation.
Irrigate the crop at 2-3 weeks interval depending on soil moisture and crop appearance.
Irrigation should be stopped as the crop approaches maturity so that the field is dry for
harvesting. It will also prevent rotting of the roots and bulbs.
h. Weeding
Good weed control is essential in garlic production. Alliums are poor competitors; weeds
can cut garlic yields in half, and lower the quality of the crop.
Garlic is usually mulched so that weeding is rarely necessary. Eliminate weeds during
early growth stages of the crop to avoid competition.
i. Harvesting
Garlic plants are ready for harvest at 110 120 days after planting (DAP) or when the
leaves turn yellow and dry. Maturity is indicated by the softening of the neck or part of
the stem just above the bulb. Harvest manually by uprooting the matured plant.
j. Drying
Before storage, trim the shoots of the bulbs sparingly with a curve-bladed shear and then
grade the bulbs. Sun dry the harvested bulbs for 7 to 10 days by spreading on concrete
pavement. Avoid sunscalding by covering each layer of bulbs with another layer of
bulbs. Place an orderly and overlay of dried lagundi leaves, Vitex negundo (Dangla)
while the bulbs are being dried at the start of storage to reduce damage by the cigarette
beetle.
