| This plant belongs to family Poaceae and
is a source of obtaining oil from leaves and shoots. This
grass provides a lemony smell and is used from various purposes
like perfumes for soaps, hair oils, scents and medicines.
Cultivation details :
Soil and climate :
It flourishes in a wide variety of soils
ranging from rich loam to poor laterite. Water logged soils
should be avoided as they are unsuitable for its cultivation.
It requires warm humid climate with plentiful sunshine and
rainfall from 225-250 cm.
Propagation :
Lemon grass can be propagated either by seeds,
vegetative propagation and rooted slips. It has been noticed
that both the both the seedlings and the rooted slips performed
equally well. But due to the high cost of transplanting, direct
seeding is widely practiced.
After this, the field is irrigated with water so that the
land becomes moist. Then the land is ploughed to 5-8 cm deep.
The ready slips are dipped in a solution prepared from cow’s
urine (one part urine to 10 part water) for 2-3 hours. Then
they are transplanted in the deep pits. The planting is done
mainly in the last week of May or first week of June. However
under irrigated condition it can be cultivated in oct-nov.
Land preparation and spacing :
The land is prepared by ploughing and harrowing,
the land is ploughed 2-3 times and farm yard manure or compost
is spread over the land. If termites are noticed, then use
of neem barks is advisable.
Lemon grass can be planted in furrows and
also in plain fields. Planting in furrows will be more profitable
and the plants spread to a large area in this type of planting.
Therefore after proper plouging & manuring one feet high
furrows are made where it is planted and the spacing between
furrows to furrows should be 2-2 feet.
Irrigation :
After planting, the crop should be irrigated
at every 3 days interval for a month. After that every 10
days it can be irrigated
Manuring :
During field preparation it requires 15 tonnes
gobar or compost. After each harvest, minimum of 2-2.5 tonnes
of gobar is put in the field. Along with this it requires
60 kg of nitrogen, 16 kg of potash and 16 kg of phosphorus.
Potash should be given once at the beginning while nitrogen
at every 2-month with an amount of 10 kg/dose.
Harvesting :
The crop is perennial in nature and gives
good yields for 5 years. Harvesting is done when it attains
a height of 3-3.5 feet, lemon grass is cut leaving 10 cm from
the ground. First harvest yields less grass but after this
it grows vigorously. After every 90-100 days interval, it
yields a good harvest. So in first year we can get 2-3 cuttings
where as 3-4 cuttings are obtained in subsequent years.
Yield :
In first year, 2-3 harvests is obtained where
as subsequent 3 years also yield 3-4 harvest. Like this the
amount of oil also increases. Oil content also depends on
the varieties, growth, time of harvest etc. 0.2%-0.6% of oil
is obtain as compared the herbage yield. First harvest yields
5-6 g oil/acre and it increases to 20 kg oil/acre.
Economics :
Yield Sale price per hectare after 5 years
–Rs.28000/- (80 kg oil @ Rs.350 / kg)
Expenditure – Rs.7500/-
Net profit/hectare/year – Rs. 20500/-
