It is of high economic importance due to its oil which has a refreshing odour because of the high citral percentage in it. The oil is used in perfumes, detergents, soaps, cosmetics, beverages, insect repellents, and even in tea preparation. The leaves are used as a herb in different cuisines and in addition to this, it offers many medicinal benefits due to its antibacterial, antifungal, and antimicrobial properties.

Lemongrass is a fragrant herb also known as a pest repellent and the smell of its oil deter unwanted insects like mosquitoes. Due to this insect repellent property, one can obtain ultimate profits from Lemongrass production by following proper crop management practices and a good marketing strategy.

Lemongrass Cultivation

The cultivation process is based on certain factors which are discussed below.

  • Climate & Soil Requirement

The crop grows well in tropical and subtropical climatic conditions with an elevation upto 900 metres above sea level and the most ideal condition would be a warm and humid climate with plenty of sunshine and evenly distributed rainfall upto 250- 330 cm. A temperature ranging from 25-30°C is better for proper growth.

Lemongrass requires medium fertile soils with the soil pH ranging from 5.0-7.0, with moderate irrigation. Well drained loamy soil is best suited for growing the crops and it can also be grown in poor laterite soil but water logged soils should be avoided.

  • Seed propagation

Propagation of seeds takes place best at nurseries through raised seeds. It can also be done by vegetative propagation by splitting the clumps into slips with a spacing of 60×80cm. For producing seedlings for 1ha of land, it requires about 2.5 kg of seeds or 55000 slips.

  • Seed Production

The flowering time for the crops is November-December and the seeds mature in February-March. The plants are maintained in good health for proper yielding at the time of collection of seeds, as a healthy plant produces 100-200 g of seeds, the seed rate being 4-5 kg/ha.

  • Nursery Raising

Nursery raised seedlings are recommended as it is better than direct sowing of seeds. The seeds are grown on raised beds on the onset of monsoon in a well pulverized soil. The nursery beds should be watered immediately after sowing and proper moisture should be maintained thereafter. Seeds start to germinate in 5-6 days and become ready for transplantation after 60 days.

  • Land Preparation

Before plantation, the land should be cleared of any unwanted weeds or previous crop residues or dead plants and pits of 5×5×5 cm should be made at a spacing of 10×15cm.

  • Planting

Seedlings are to be planted at a distance of 40×40cm, 40×60cm, or 40×30cm apart, depending upon land fertility and Intercultural operations used on it. For areas of high rainfall  it is better to plant the crops on ridges. For rooted slips, a deep hole of about 15cm is made and are placed with 1 or 2 slips in each hole.

  • Irrigation

Irrigation depends on the season & moisture holding capacity of the soil. After transplantation, irrigation is a must. For summer months 4 to 6 irrigations are recommended and in rainy months it is not required. If rains are unpredictable, the field should be irrigated after every 3 days for the first months and thereafter at a 7-8 days interval.

  • Manures & Fertilizers

Before plantation, the soil should be added with organic compost or farmyard manure. At the time of planting of crops, it is recommended to apply 30kg of Nitrogen, 30kg of P2O5 and 30kg of K2O as a basal dose per hectare.

60 to 90 kg of Nitrogen should be applied during the growing season in splits of 3 to 4 as a top dressing, and for low fertile soils amount of Nitrogen should be increased. 25 to 60 kg/ha of Zinc Sulphate is also added in Zinc deficient soils. It also requires micronutrients in marginal lands, although it is free from pests & diseases.

  • Intercultural Operations

After plantation, it is recommended to keep the field free of weeds for the initial 3 to 4 months and weeding plus hoeing should be done upto 1 month after every harvest, and 2 to 3 weeding operation is essential in 1 year time period. Tractor down cultivators or hand hoe can be used in case of row plantation.

For controlling weeds, the distillation waste is used as an organic mulch and is applied @3tonnes/ha. Among herbicides, Diuron @ 1.5kg ai/ha and Oxyfluorfen @ 0.5kg ai/ha are effective for controlling weeds.

  • Pests & Diseases

Lemongrass records several pests & diseases which causes only minor damage and loss of crop is also very less. But for higher yields and quality crops, it must be kept free from these pests too.

Some of the pests and their control are:

  1. Stem Boring Caterpillar – It feeds on the stem of the plants making the leaves dry which results in significant reduction of yield of the grass.

Control Measures:

  • Apply Folidol E 605.
  1. Nematodes – It infects the plant.

Control Measures:

  • Apply Fenamiphos @ 11.2kg/ha.

Some of the diseases and their control are:

  1. Red Leaf Spot – Brown colored spots are seen on the lower surface of leaves and become bigger patches afterwards making the leaves dry.

Control Measures:

  • Apply 2 sprays of Bavistin @ 0.1% just after the emergence of the disease at 20 days interval.
  • App 3 sprays of Dithane M-45 @ 0.2% at 10-12 days interval.
  1. Leaf Blight – Leaves are shown with reddish brown spots resulting in premature drying of leaves.

Control Measures:

  • Spray 0.2% of Dithane Z-78 or 0.3% of Copper oxychloride at 15 days interval.

  1. Little Leaf or Grassy Shoot – The growth becomes stunt and little leaves are formed in place of normal inflorescence.

Control Measures:

  • Spray 0.3% of Dithane Z-78 just before flowering stage at 10-12 days interval.
  • Use fresh seedlings for planting and crop rotation.


The flowering season is in Winter and after transplantation the first harvesting is done after 4 to 6 months.

Thereafter, it is done after every 60-70 days depending upon the season and the soil fertility. Harvesting can be done using Sickles, where the plants are cut 10cm above ground level, and before taking it to the distillation site it is allowed to wilt in the field. Oil is extracted by water or steam distillation method.

  • Yield

Lemongrass plantation lasts on an average of 3 to 4 years. The yield depends upon the soil and climatic conditions. For the first year, the oil extracted is less, then it increases in the second year and is maximum in the third year and again starts declining after this.

From 4 to 6 cuttings per year, the yield is about 25 to 30 tonnes of fresh herbs per hectare on average, yielding 80kg of oil. Under irrigated conditions for newly bred varieties of the crop, the yield can be 100-150 kg/ha. Before distillation thick stems are devoid as it lacks oil and every fresh herb contains 0.3% of oil on average.

Cost Economics for Lemongrass Farming:

Cost Economics for Lemongrass Farming
S.No. Total Cost of Production Qty Unit Rate 
1 Seed cost of Moringa 1500 Rs Kg
2 Field Preparation 3000 Rs Per acre
3 Labour Cost 6000 Rs Per acre
4 Fertilizer & pesticides  12000 Rs Per acre
5 Weeding Cost 5000
6 Irrigation & Harvrsting cost 3000
7 Cost of Production 30500
8 Yield 5000 Kg Per acre
By the selling of fruit @ Rs 15/Kg 75000
Yield – Cost Ratio 75000-30500=44500
  • Post Harvest
  1. The grass is allowed to wilt for 24 hours before distillation as it reduces moisture and improves oil yield
  2. The oil is distilled using water or steam distillation and it takes around 4hours for completing the process.
  3. The insoluble particles in the oil are then removed by filtration method using anhydrous Sodium Sulphate mixed with it and kept overnight for 4 to 5 hours. Steam rectification process is used when the color of the oil changes due to rusting.
  4. The oil is stored in glass, aluminum,steel or galvanized iron containers depending upon the quantity of oil to be stored. The containers are to be kept away from direct heat/ sunlight.
