Lemongrass cultivation project report, process of growing, investment, and profit per acre in India

In India, only 0.03 percent of the farmers practice lemongrass cultivation per year.

Neither any animal eat lemongrass nor any kind of fungal infections or diseases touch the lemongrass. Sometimes it's leaves get dry because of dryness and they become green again in presence of moisture, otherwise lemongrass is healthy plant that grow for the whole year.  

Once you plant lemongrass, you will get the yield for the next five years on a certain difference of time. Maximum, you can get three to four(sometimes) yields of lemongrass per year. You don't need to sow another lemongrass cuttings till the time. 

Lemongrass cultivation project report(1-acre)

The main purpose of the cultivation of lemongrass is to get the lemongrass plant oil. This lemongrass oil uses in the making of detergent, soap, cosmetic products, and some particular medicines.

People get confused about yield, investment, and profit per acre before getting start lemongrass cultivation. Let's understand how lemongrass cultivation works and what are basic requirements(including investment).

Requirements for lemongrass cultivation

Following are basic and fundamental requirements for lemongrass cultivation-

  • Temperature and humidity

The ordinary temperature must not be more than 30 degrees Celcius, and not lower than 10 degrees Celcius during sowing of lemongrass cuttings.

For mid-growth temperature can vary. The lemongrass plant can handle higher temperatures or lower temperatures during mid-growth. At the time of harvesting, the temperature must be moderate.

If humidity is very high at the time of sowing, then there is no extra requirement of irrigation water soon, but if you are sowing lemongrass cuttings in the offseason, then you have to do it with plenty of irrigation water.

Normally, in the month of September, humidity increase to very high, that's why this ideal month helps at the time of sowing.  

  • Soil type and pH 

One of the major advantages of lemongrass cultivation is that it can grow in almost every kind of soil. But still, there are debates on desert soil for lemongrass cultivation.

For lemongrass, soil pH must be between 6.5 to 7.3 on the pH scale.

  • Fertilizers

For lemongrass, people use some basic chemical fertilizers but it is better to use organic compost instead of chemical fertilizers. In the recent period, it is noticed that organic compost provides better and faster results in comparison to chemical fertilizers without any side effects on plant growth.

For one acre land 5 quintals of organic compost is enough at once in a liquid form with water with ratio of 1:2. 

  • Irrigation water

It is certain that there is no high demand for irrigation water for lemongrass. It doesn't mean that there is no need for water for lemongrass plants to grow. But when moisture in the air doesn't help the plants then the participation of irrigation water increases. 

For mid growth, some amount of irrigation water is required per duration of 40 to 45 days and the last irrigation is just 10 days before harvesting. 

Oil making vapor tank 

The ideal size of the vapor tank to separate the oil from the lemongrass plants is 5000 liters. 

The total vapor plant requires land of 15x10 square meters. 

Sections of oil making vapor tank plant 

  • The vapor tank

This vapor tank is cylindrical with a 5000 liters capacity. It has a big cap of metal on the top that is associated with a pipeline. This pipeline goes through the cold chamber of water. This pipeline end in a collecting drum to separate the oil from the yield. 

  • Heat furnace chamber

Before making a vapor tank, a huge hole dig in the ground, and then the tank keep over it. Later, it works as a chamber to provide heat directly to the tank.

Vapor tank working principle to separate lemongrass oil

It works on the principle when lemongrass keeps in the vapor tank which is already filled half with water. It produces vapor mixed with the oil of lemongrass plants. 

It goes through the pipeline associated with the colling chamber and then collects in form of liquid in a drum. Because water and oil don't mix with each other, oil starts to float as the upper layer of liquid.

Hence, it separates later and it is pure produced lemongrass oil. 

Cuttings of lemongrass

In one acre of land, a total of 18000 to 20000 cuttings are required for cultivation. With a  mortality rate of 3%, the number of lemongrass cuttings becomes less and covers the 1-acre land. 

You can bring lemongrass cuttings from a local nursery or a local lemongrass farmer. If none of them are available in your area, then you can call or order from online individuals.

Process of lemongrass cultivation

Let's understand lemongrass cultivation in steps-

Land preparation 

The first step of lemongrass cultivation is land preparation. Check the soil pH and plow it properly. Keep the land moist with irrigation water. Instead of direct irrigation water, you can use liquid organic compost. This will provide an easy mix of compost with the soil and plenty of moisture for lemongrass sowing. 

After mixing compost with soil, you can make small soil beds similar to the line-to-line distance of cuttings. 

Sowing of lemongrass cuttings

Lemongrass cuttings angle of pinching in the ground is not similar to super Napier grass. Each of the lemongrass cuttings pinches and keeps on 70 to 100 degrees.  

On one acre or 80x50 square meter land, following distance maintenance is important during sowing of cuttings-

  • The line-to-line distance 

The line-to-line distance must be 0.50 m for each row. Maximum 100 lines are possibles with 200 columns of lemongrass cuttings. It means there are around 100 cuttings can sow in rows. 

  • Plant to plant distance

The plant to plant distance must be 0.40 meters with each other. This wide space provides a place to get full bushy growth for lemongrass plants. 

In one acre of land(80x50 square meters), maximum of 200 cuttings can sow at once in columns. 

With this calculation, total space for 200x100 cuttings is available, in that you can sow 18000 to 20000 cuttings of lemongrass. 

Irrigation of lemongrass

There is only a few quantity of irrigation water is required in lemongrass cultivation. 

First cultivation must start between the 40th to 55th day of sowing. Second irrigation follows after the 80th day and so on. But important thing is that you should provide irrigation water to plants just 10 to 15 days before harvesting. 

In one acre of land, at once 10 to 12 thousand liters of water is required.  

Fertilizers and Composting 

Fertilizers are not necessarily required for lemongrass plants. But to maintain soil pH and proper elements required for plants, 3 to 5 times compost can provide to all the plants during the whole year.

Either you can use liquid compost(animal dung compost mixed with water with a ratio of 1:3) or use dry compost and irrigation water separately.  

But more helpful is liquid compost. It reduces the requirement of separate water for irrigation. 


Lemongrass plants require weeding only a few in a harvesting cycle. Because of the low moisture in the soil, the spontaneous plants don't appear in a large number. But still few plants appear in mid-growth, so their separation is required.

Weeding must be done two to three times in a harvesting cycle on a certain difference of time.

Harvesting lemongrass

Harvesting of lemongrass is similar to super Napier grass harvesting. For that, you need to cut the green portion of the plant just above the ground. If a plant is 3 feet tall, then cut the green section 8 to 10 cm above the ground. 

After harvesting, let the remaining portion of the plant get ready for the next harvesting. 

Lemongrass yield per acre in India

Lemongrass total yield depends on how many times it is harvested in a year. Most people believe that 3 times a year is enough to harvest the lemongrass. 

Period and yield of harvesting lemongrass 

The first-year cycle of harvesting
  • Yield in first harvesting(After 5 months)- 6 Tons 
  • Yield in second harvesting(in next 3 months)- 5 Tons
  • Yield in third harvesting(in next 3 months)- 6 Tons

  • Yield in first harvesting(after first 4 months)- 4 Tons 
  • Yield in second harvesting(in next 5 months)- 5 Tons 
  • Yield in third harvesting(in next 3 months)- 5 Tons
Total yield- 14 Tons

  • Yield in first harvesting( after 3 months)- 5 Tons 
  • Yield in second harvesting(in next 5 months)- 4 Tons
  • Yield in third harvesting( in next 6 months)- 4 Tons
Total yield- 14 Tons

In it's lifetime, lemongrass yield harvest 60 to 61 Tons of green portion to collect the oil from per acre land. 

Investment in lemongrass cultivation per acre per annum

One time investment

  • Cuttings cost(once in 4 years)- 5000 INR
  • Oil vapor tank and chamber(once in 15 years)- 50,000 INR 
Total cost- 55,000 INR

Spirulina farming, project report per 1/4th acre, investment, profit per 1/4th acre, and challenges

There are very less veg options available that have the same or higher percentage of protein than meat. Spirulina is high in protein, quality diet, high in minerals, and we can consume them without cooking. Often, people call it future food.  There are very less farms of spirulina farming so its market price is very high. The spirulina farming business will become more profitable in the future. Let's understand the spirulina farming and project report for 1/4th acre. Spirulina farming  What is spirulina? Spirulina is a sea algae. Spirulina contains one of the highest percentages of protein in all diets. Vitamin B, K, antioxidants, and amino acid are some of the other major components of spirulina. One you start spirulina farming, you can harvest for next 5 months without adding or preparing any new culture.  There are two types of spirulina; human consumption and animal consumption.  We can harvest animal spirulina in the open-air pond but for human consumption, we use either a pol

Planter machine in agriculture, sections, types of planter machine, and working process

It is a big problem to sow seeds precisely. Sometimes, we scatter multiple seeds in a single spot, sometimes, spots are left empty. Also, it is hard to keep the line-to-line distance and plant-to-plant distance accurate all the time in bigger lands. This irregularity with seed sowing is very common but a big problem in traditional crop cultivation. In small fields, it is possible to check the regular pattern of seed sowing but in big hectares of land, it is almost impossible to count the regularity of seeds at the right spot.  Planter machines are very helpful to solve the problem. Let's understand the working of planter machines and their types. Planter machines in agriculture Planter machines help to sow seeds precisely in agricultural fields. It works automatically in multiple sections and maintains the line to line distance and seed to seed distance with correct accuracy. Planter machines operate from diesel and petrol.  Most of the planter machines are available as complementa

Murrah buffalo, milk per day, price, dairy farming project report for 10 Murrah buffalo

People argue about cow milk and buffalo milk's qualities for health. Some people love cow milk and some like buffalo milk.  Although both kinds of milk are a source of fat, carbohydrates, protein, etc.  It is true that cow dairy farming is a profitable business, but on the same note, it is also true that buffalo dairy farming is a profitable business idea.  One of the most popular buffalo is the Murrah buffalo in terms of starting a dairy farm. So you are going to get full info and a project report to understand the terms of requirements, investment, and profit margin.  Murrah buffalo and milk production  We will start with how to identify Murrah buffalo.  How to identify the Murrah buffalo? Size - Murrah buffaloes are big size animals. The average size of the Murrah buffalo is like a Sahiwal cow and sometimes bigger than that.  Head and horns - Murrah buffalo's head size is average like other buffaloes. The horns are not too big but still thick and curved towards each other. 

45 days chicken(broiler) business plan, requirements, license, investment, and profit calculations

With the increasing demand for chicken in the market, it was always difficult to raise chicken faster. In 3 months period, poultry farms' reach was not effective in all the places. But 45 days chicken business plan fulfills the requirement, demand, and supply in the market of chicken.  Let's understand how 45 days chicken poultry farm works and what are the requirements to have a poultry farm. 45 days chicken(Broiler) business plan What is poultry farm business of 45 days? Broiler chickens are one of the fastest-growing chickens. The main reason for the short-term 45 days chicken business plan is demand and supply in the market. Chicken demand is so huge in the market. If we follow poultry farms with more than 3 months of breeds, then it can affect the stability of chickens in the market. It can increase inflation.  One more thing to starting 45 days chicken farm is because it gives a faster profit margin to the owner. Also, 45 days chicken farm is good to raise and handle a hu

Goat farming, project report(20+1), requirements, investment, and profit in 2022

People are encouraged to start a goat farm after seeing the profit of other goat farms. Although it is a good business model, people don't care about the consequences of bad implementation and lack of knowledge.  So we suggest you get physical training first and then follow this project model. Let's understand how to develop goat farms, goat breeds, methods of implementation, precautions, investment, and profit of goat farming business on 20+1 goats. Goat farming  Working of goat farming business model The goat farming business works for two purposes; for meat and milk. For 20 goats, people usually take 1 male-goat, but sometimes you can take 2, it depends on you. Reason is simple, because people believe that 1 is a lucky number. People consume Goat meat more than goat milk, which is why most people establish it for meat. But actually, a bigger number of goats can generate a good income from milk alone. To raise goats for meat,  there is a principle of increasing production.  G
