is an important bulbous vegetable believed to have been
originated in Central Asia.It has many medicinal properties.It
is a herbaceous annual (for bulb production). The underground
bulbs are cream in colour with or without pink tinge.
The compound bulb consists of 10-20 bulblets or segments
called cloves. These cloves are covered by a parchment
membrane. The uninjured bulb contains a colourless odourless
water soluble aminoacid called 'allin'.On crushing the
bulb,the enzyme 'allinase' acts on 'allin' to produce
'allicin'. The characteristic odour is due to diallyl
Garlic requires cool and moist period during vegetative
growth and a dry spell during maturity of the bulbs.
Fertile, well-drained loamy soils are ideal for garlic
cultivation. Heavy clay soils may result in deformed
bulbs. In high ranges of Kerala garlic can be planted
Cloves or bulbils are used for propagation. For planting
one hectare, 500 kg of cloves is required. The cloves
for planting should be stored for 2-3 months after
harvest and cloves weighing 4 g are ideal for planting.
The cloves should be soaked in water followed by dipping
for 15 minutes in a solution containing 1 ml of dimecron
and 1 g of carbendazim dissolved in 1 litre of water
for 15 minutes. After drying in shade, cloves can
be used for planting.
Dig the land thoroughly and prepare beds of 15 cm
height at a width of 1 m and of convenient length.
The cloves should be dibbled at a spacing of 15 x
8 cm. Germination will start on the fifth day and
it will be completed within 10-15 days.
Earthing up should be done 60 DAP
the initial stages of crop growth frequent irrigations
are given to encourage vegetative growth .i.e. once
in a week. Irrigation intervals are increased with crop
maturity and finally irrigation is with held.
Apply N:P2O5: K2O @ 60:120:120 kg/ha 20 days after
transplanting (DAP). Topdressing of N should be done
@ 60 kg/ha, 45 DAP.
and hoeing are done as and when necessary. Being a closely
planted crop, inter cultural operation has to be done
with utmost care avoiding crop injury.
To control thrips and foliar nematode, spray 1 ml of
dimecron dissolved in 1 litre of water. To control blast,
spray mancozeb (2 g/litre).
can be done 120-130 DAP.
