Palmorosa
Palmorosa – Cymbopogan martini 
Soil and Climate –
The crop
grows bet in sandy loam soil with good water drainage. It can be grown in both
slightly acidic and slightly alkaline soils, but a soil pH between 6.5 to 7.5
gives the best results. Tropical and subtropical climates are ideal for this
crop. High humidity, around 88%, is important for healthy plant growth.
Cultivation –
Sowing is
usually done from the end of May to early June. Rows should be kept 60cm apart,
and plants should be spaced 30cm from each other. Gap filling or thinning
should be done whenever needed to maintain proper plant population. The soil
should have good moisture, around 70%, at the time of sowing. Well-decomposed
farmyard manure should be applied fully at sowing.
Seedlings that are 3-4 weeks old are transplanted into the field, and
irrigation should be given immediately after transplanting. During winter, two
irrigations are enough, while in summer, 3-4 irrigations are required. Care
should be taken to avoid water stagnation, as excess water can severly damage
the crop.
Since this is a perennial crop, it needs adequate nutrients every year.
About 150 kg Nitrogen, 60 kg phosphorus, and 50 kg potash per hectare per year
should be applied for healthy growth and good yield.
Harvesting –
The first harvest can be done about 7 months after planting.
After that, the crop can be harvested multiple times, with intervals of 2-3
months between harvests. While harvesting, cut the crop 15-20 cm above the
ground.
Yield –
A hectare of
this crop can produce around 20 tonnes of grass, containing 0.4-0.5% oil. This
gives about 150-180 kg of palmarosa oil per hectare. Grass should be harvested
during its flowering stage, usually in October – November, February – March,
and June – July. Oil yield may vary depending on the timing of harvest and the
overall growth of the plants.
