Production Technology of Garlic _ Bangladesh

Land andsoil

Garlic can be cultivated in various types of soils but well drained fertile loamy soil is

suitable for this crop.

Seed rate

The amount of planting material required varies from 700-1000 kg/ha, depending

upon the weight of individual cloves planted and the spacing used.

Seed treatment

• Soak the selected cloves for 5 minutes in a solution of Ipridione (3 g/l) and Tufgor

(2 ml/l).

This is a high yielding variety developed through

selection procedure. Plant height: 60-62 cm and 7-8

leaves per plant. Number of cloves per bulb varied

from 20-22 and weight of bulb: 19-20g. Very good

keeping quality. This variety is more tolerant to virus

and soft-rot disease. Disease and pest infestation is

comparatively less. It is a rabi (winter) season crop.

Bulb yield: 6-7 t/ha. Duration: 140-150 days.

(2004)

High yielding variety. Plant height: 56-58 cm and 9-10

leaves per plant. Number of cloves per bulb: 23-24 and

weight of bulb: 22-23g. Very good keeping quality. It

takes more time to maturity depending on the weather

condition. Resistance to viral disease. This variety has

less infestation of pest and disease. It is a winter season

crop. This variety is cultivated in all areas of Bangladesh.

Bulb yield: 8-9 t/ha. Duration: 145-155 days.

• The treated cloves are then dried in shade till these are free from moisture by

spreading on the floor. Then the cloves are ready for planting for the next day.

Time of sowing

Last week of October to 1st week of November is the suitable time for planting of garlic.

Sowing method

Garlic can be planted by following ways:

• Dibbling- Fields are divided into small plots convenient for irrigation.

• Furrow planting- Furrows are prepared at appropriate spacing (15 cm x10 cm) with

hand hoe.

• Broadcasting-Cloves are scattered evenly in well leveled field/seed beds by hand.

Land preparation

Land should be brought to fine tilth by shallow ploughing 4-5 times, giving sufficient

interval between two ploughings. Land should be levelled and divided into small

plots and channels to facilitate proper irrigation and intercultural operations.

Fertilizer dose and application method

* DAP= Days after planting

Full dose of cowdung should be incorporated in the soil at the time of land

preparation. Full dose of TSP and gypsum should be applied as basal dose at the time

of planting. Half amount of urea and MP should be applied at the time of final land

preparation and the rest amount of urea and MP should be applied as top dress after

60 and 90 days of planting. If necessary, urea should be given at 110 DAP.

Irrigation

During land preparation, if soil moisture is not sufficient, it is necessary to irrigate the

field a day or two days earlier. In case the soil becomes too wet after irrigation, the

field should be allowed to dry until the desired moisture level is attained. Enough

moisture is essential within the root zone during the vegetative growth. The

frequency of irrigation depends on the soil type and occurrence of rainfall during the

growing period. Clay loam soils are required three times irrigation but sandy soil

requires frequent irrigation. Flash irrigation can be applied when crevices or cracks

on clay loam soils appear. Water should never be allowed to stay in the field beyond

six hours. Irrigation starts just after planting and ends 20 days before harvesting.

2.3 Intercultural Operation

Generally 2 to 3 weedings are needed. First weeding should be done one month after

planting, second one month after first weeding and third at later stage of crop. Hoeing

at the time of bulb formation (75 DAT) helps in setting of bigger well filled bulbs.
