Why Cassia? A Strategic Choice for the Forward-Thinking Bihari Farmer
In the agricultural landscape of Bihar, where farmers constantly seek to balance tradition with profitability, a quiet revolution is taking root. This revolution smells of spice and opportunity. We are talking about Cassia (Cinnamomum cassia), the robust, aromatic spice that most of India knows and uses as ‘Dalchini’. For too long, our focus has been on short-cycle food crops, leaving us vulnerable to market fluctuations and climate risks. Cassia offers a different path: a long-term, high-value perennial crop that can transform a piece of land into a legacy of sustained income.
Why now? Because the demand for authentic, locally-sourced spices is soaring. Consumers are more aware, and markets are rewarding quality. Furthermore, Bihar’s sub-tropical climate, particularly in the northern and eastern belts, is remarkably well-suited for Cassia cultivation. It is not a crop for the impatient, but for the wise farmer who understands that the greatest rewards come from patient, strategic investment. This is not about replacing paddy or wheat; it is about smart diversification. It is about converting a portion of your land, perhaps one that is not ideal for intensive annual crops, into a high-earning asset that will yield returns for decades.
This article is your guide to that path. It is rooted in phronesisβpractical wisdom. We will go beyond theory and provide you with actionable steps to establish, manage, and profit from a Cassia orchard. From preparing the soil to the art of harvesting the fragrant bark, this is your complete manual for Cassia farming in Bihar.
Understanding Cassia: The Market’s Favourite ‘Dalchini’
Before we put a single sapling in the ground, it’s crucial to understand what we are growing and why. The spice shelf can be confusing. What many call ‘Dalchini’ in the market is actually Cassia.
- Cassia (Cinnamomum cassia): This is our focus. It is also known as Chinese cinnamon, but it is widely grown across Asia. Its bark is thicker, darker reddish-brown, and forms a double-scroll quill when dried. The flavor is strong, spicy, and pungent. It is robust, higher-yielding, and dominates the global spice trade. This is the commercially smart choice for cultivation in Bihar.
- True Cinnamon (Cinnamomum verum): This is native to Sri Lanka. Its bark is paper-thin, light tan, and forms multiple fine layers in a single quill. The flavour is more delicate, sweet, and subtle. While a premium product, it is less hardy and lower-yielding, making it a more challenging crop for our region.
For a farmer, this distinction is everything. By choosing Cassia, you are choosing a crop with proven market demand, robust genetics, and greater adaptability to Bihar’s agro-climatic conditions. The leaves of the Cassia tree are also the ‘Tejpat’ or Bay Leaf used in Indian cooking, providing a valuable secondary income stream. So when we say Cassia, we are talking about a dual-income crop: Dalchini from the bark and Tejpat from the leaves.
The Foundation: Selecting the Right Site and Preparing the Soil
A Cassia tree can be productive for over 30 years. Such a long-term commitment demands a strong foundation, and that foundation is the soil. Getting this part right is non-negotiable.
Site Selection in Bihar
Cassia is not suited for every corner of the state. It thrives in regions with good rainfall and avoids extremes of heat and cold. The ideal locations are in North and North-Eastern Bihar, in districts like Kishanganj, Araria, Purnia, Katihar, and parts of Supaul and Madhubani. These areas offer the required rainfall (1200-2500 mm) and humidity.

When choosing a specific plot on your farm, look for:
- Excellent Drainage: This is the single most critical factor. Cassia roots cannot tolerate waterlogging. Avoid low-lying areas or heavy clay soils (‘cheetal’ or ‘karail’ mati) that hold water. Sloping land is ideal. If your land is flat, you must ensure it has a gentle, imperceptible slope and create drainage channels.
- Partial Shade (for young plants): While mature trees love sun, young saplings benefit from partial shade. Planting near existing orchards or where you can intercrop with taller plants can be beneficial.
- Protection from Strong Winds: Windbreaks of taller, hardy trees like Sheesham or Eucalyptus on the periphery of the plot can protect the brittle Cassia branches.
Soil Requirements and Preparation
Cassia prefers a deep, fertile, and well-drained soil. Sandy loam (‘domat’) to loamy soils are perfect. The ideal pH range is slightly acidic, between 5.5 and 6.5. Most soils in the target districts fall within or close to this range.
The real work begins with preparation, ideally done in the hot months of April-May:
- Deep Ploughing: Plough the land to a depth of at least 30-40 cm (about 1.5 feet). This breaks up any hardpan and improves aeration and root penetration. Follow this with 2-3 rounds of harrowing and levelling.
- Incorporate Organic Matter: This is the secret to long-term soil health. Before the final harrowing, spread a layer of well-decomposed Farm Yard Manure (FYM) or compost. Aim for a generous application of 15-20 tonnes per hectare (about 6-8 tonnes per acre). This improves soil structure, water-holding capacity, and provides a slow release of nutrients.
- Layout and Pit Digging: Mark the field for planting. The pits are your sapling’s first home. They need to be prepared well in advance. More on this in our step-by-step guide.
From Seed to Sapling: Propagation and Planting Techniques
Your future orchard’s success depends on starting with healthy, vigorous planting material. Cassia can be propagated through seeds or vegetative methods.
Propagation Methods
- From Seed (Most Common): Seeds are collected from mature, healthy trees between June and August when the fruits turn blackish-purple.
Critical Point: Cassia seeds have very short viability. They must be sown within a week of collection. Never buy old, dry seeds. The flesh of the fruit contains germination inhibitors, so it must be completely removed by washing and rubbing the seeds with sand or ash. The cleaned seeds should be soaked in water for 24 hours before sowing in nursery beds or polybags. - Vegetative Propagation (For Superior Plants):
- Cuttings: Semi-hardwood cuttings (15-20 cm long) can be taken from healthy shoots and treated with a rooting hormone before planting in a nursery. This method ensures the new plant is a clone of the parent tree.
- Air Layering (Gootee): This is a reliable technique where a section of a branch is girdled and induced to root while still attached to the parent plant. It has a high success rate but is more labour-intensive. Vegetative propagation is best for expanding an existing orchard with known high-quality trees.
Nursery Management
Raising seedlings in a nursery for 9-12 months before transplanting is the standard practice.
Fill polybags (size 15cm x 25cm) with a mixture of soil, sand, and well-rotted FYM in a 2:1:1 ratio. Sow one treated seed per bag. The nursery should be in a shaded location, and bags must be watered regularly. After about 6-8 months, the shade should be gradually reduced to ‘harden’ the saplings, preparing them for the open field.
Step-by-Step Planting Guide for a Successful Cassia Orchard
Follow this timeline for a flawless start. This process turns a piece of land into a productive Cassia plantation.
- Summer (April-May): Pit Preparation
- Based on your field layout, dig pits of 45cm x 45cm x 45cm.
- Spacing is crucial: For bark production, a spacing of 2.5m x 2.5m is ideal. This accommodates about 1600 plants per hectare (or 640 plants per acre). This density promotes straighter growth and is efficient for management and harvesting.
- Keep the excavated topsoil and subsoil separate. Let the pits bake in the sun for 2-3 weeks. This ‘solarization’ kills harmful soil pathogens and pests.
- Early Monsoon (Early June): Pit Filling
- Prepare a rich mixture for each pit. Combine the reserved topsoil with 5-7 kg of well-rotted FYM or vermicompost, 250g of neem cake (for pest and nematode protection), and 100g of rock phosphate.
- Refill the pits with this enriched mixture. The soil level should be slightly raised to allow for settling.
- Monsoon (Late June – July): Planting
- Choose a cool, overcast day, preferably after a good rain shower. The evening is the best time to plant.
- Select healthy, hardened saplings that are 9-12 months old.
- Carefully make a cut in the polybag and place the entire root ball into the center of the refilled pit without disturbing it.
- Ensure the plant is at the same depth it was in the polybag. Press the soil firmly around the root ball to remove air pockets.
- Water immediately and thoroughly, even if the soil is moist.
- Years 1-3: Establishment Phase
- Weed Control: The young plants cannot compete with weeds. Keep the basin around each plant clean through manual weeding or heavy mulching.
- Gap Filling: Monitor the field and replace any saplings that die within the first few months.
- Shading: If planted in a very open field, you might need to provide temporary shade for the first summer. Intercropping, discussed next, is a better way to achieve this.
- Year 3-4: The First Coppicing
- This is a pivotal moment. To encourage the growth of multiple harvestable stems from the base, the main stem is cut down. This is called coppicing.
- When the main stem reaches a height of about 3-4 meters and a girth of 10-12 cm at the base, cut it at a height of 10-15 cm from the ground.
- This will induce a cluster of new shoots to sprout from the stump, forming a ‘bush’. These shoots will be your first harvest in the coming years.
Orchard Management: Nurturing Your Long-Term Investment
Once planted, your work shifts from establishment to nurturing. A well-managed orchard is a productive orchard.
Nutrition and Fertilization
Cassia is a heavy feeder. Regular nutrition is key to vigorous growth and high-quality bark.
Latest Articles
- Organic First: The foundation is always organic matter. Apply 10-15 kg of FYM or compost per plant every year, just before the monsoon. Spread it around the basin of the plant, away from the main stem.
- Balanced Chemical Fertilizers: To supplement organic inputs, a balanced NPK application is recommended. A general schedule could be:
- Years 1-3: 20g N, 18g PβOβ , 25g KβO per plant per year.
- Year 4 onwards (after coppicing): Increase the dose to 90g N, 25g PβOβ , 60g KβO per plant per year.
Split the annual dose into two applications: the first with the onset of monsoon (June-July) and the second in the post-monsoon period (September-October).
Irrigation and Water Management
In Bihar’s climate, Cassia can be grown as a largely rain-fed crop once established. However, irrigation is critical during two phases:
- Young Plants (First 2-3 years): They need regular watering during the dry winter and summer months.
- Prolonged Droughts: Even for mature plants, life-saving irrigation during a long dry spell can prevent stress and yield loss.
Mulching with paddy straw, dried leaves, or grass clippings around the plant basin is a highly recommended practice. It conserves precious soil moisture, suppresses weeds, and adds organic matter as it decomposes.
Intercropping for Early Income
The 3-4 year waiting period before the first harvest can be a challenge. Smart intercropping is the solution. In the wide space between Cassia rows, you can cultivate shade-tolerant crops for the first 2-3 years.
Excellent intercrop choices for Bihar include: Ginger, Turmeric, various beans, and some short-duration vegetables. These crops not only provide you with an early income but also help in weed suppression and improve soil health.
Pest and Disease Management: An Integrated Approach
Healthy, well-nourished plants are your first line of defense. However, you must be vigilant. Here are the common culprits and their practical management.
Common Pests
- Cinnamon Butterfly & Leaf-eating Caterpillars: They feed on tender leaves, affecting young plants the most.
Management: In small plantations, hand-picking is effective. For larger areas, spray Neem oil (5ml per litre of water) or a formulation of Bacillus thuringiensis (Bt), which is a bio-pesticide safe for the environment. - Stem Borers: These are the most dangerous pests. The grub tunnels into the shoots and stems, causing them to dry out. Look for small holes with a sawdust-like powder (frass) coming out.
Management: Prune and destroy affected branches immediately. In severe cases, a long wire can be inserted into the hole to kill the grub, or a cotton swab dipped in a mild insecticide can be plugged into the hole. Maintaining a clean orchard reduces borer incidence.
Common Diseases
- Leaf Spot and Blight (Colletotrichum gloeosporioides): Brown to grey spots appear on leaves, especially during humid monsoon months, leading to defoliation.
Management: Ensure good air circulation with proper spacing and pruning. Remove and burn fallen, infected leaves. As a preventive measure before the monsoon, a prophylactic spray of 1% Bordeaux mixture or Copper Oxychloride (3g/litre) is effective. - Root Rot (Phytophthora cinnamomi): This deadly disease is caused by waterlogging. Plants wilt, leaves turn yellow, and the plant eventually dies.
Management: Prevention is the only cure. Ensure perfect drainage from day one. Drenching the soil around the plant base with a solution of Trichoderma viride (a beneficial fungus) can help protect the root zone from pathogens.
The Harvest: Reaping the Aromatic Reward
Patience pays off. The art of harvesting Cassia is a skill that directly impacts your income. It’s a cyclical process that begins 4-5 years after planting.
When and How to Harvest
- Timing: The best time to harvest the bark is after the monsoon, from September to November. During this period, the sap flow is high, making the bark easy to peel.
- The Coppicing Cycle: Harvesting is not about cutting the whole tree. It is about selectively harvesting shoots from the coppiced bush.
- Select shoots that are 2-3 years old, have a smooth brown bark, and a diameter of about 1.5-2.5 cm at the base.
- Cut these selected shoots close to the ground (about 10-15 cm high), leaving the stump intact. The bush will continue to produce new shoots for the next cycle. This is a sustainable, continuous process.
- From a single coppiced bush, you will harvest 3-5 shoots every 2 years.
Post-Harvest Processing: The Key to Quality
The value of your Cassia is determined here. Rushing this step will cost you money.
- Scraping: Using a special curved knife, scrape off the greyish outer corky layer of the bark from the cut shoots. This is done immediately after harvesting.
- Peeling: Make a long slit down the length of the shoot and carefully peel the inner bark using a peeling knife. It should come off in large sheets.
- Drying: The peeled bark sheets will naturally curl into ‘quills’ as they dry. Dry them in a clean, well-ventilated, shady place for 4-5 days. Never dry in direct sunlight, as it will cause the volatile oils, which give Cassia its aroma and value, to evaporate.
- Grading & Storage: Once completely dry and brittle, the quills can be graded based on their size, thickness, and colour. Store the finished product in airtight jute bags in a cool, dry room away from sunlight and moisture.
Don’t forget the leaves! The leaves can be harvested, dried in the shade, and sold as ‘Tejpat’, providing a regular, additional income.

Yield and Economics: The Long-Term Profit Picture
Is it profitable? Yes, but it’s a marathon, not a sprint.
Expected Yield
Yields vary with management, age, and soil. For a well-managed orchard in Bihar, here are realistic expectations (per acre):
| Year | Activity | Expected Dry Bark Yield (per acre) |
|---|---|---|
| Year 1-3 | Establishment & Intercropping | 0 kg |
| Year 4-5 | First Harvest | 80 – 100 kg |
| Year 6-9 | Increasing Yields | 150 – 250 kg |
| Year 10+ | Mature Orchard | 300 – 400 kg |
Additionally, you can expect an annual harvest of 100-150 kg of dry leaves (Tejpat) per acre from the third year onwards.
The Economics
- Initial Investment: The main costs are in land preparation, quality saplings (around 640 per acre), and labour for the first 3 years. Intercropping helps offset some of this.
- Revenue: The market price for dry Cassia bark fluctuates but generally ranges from βΉ200 to βΉ350 per kg for good quality produce. At a conservative price of βΉ250/kg, a mature orchard yielding 300 kg/acre could generate a revenue of βΉ75,000 per acre from bark alone, plus additional income from Tejpat.
The Verdict: The initial years require investment and patience. But once the coppicing and harvesting cycle begins, a Cassia orchard provides a steady, low-labour, high-value income stream for a generation, far surpassing the returns from many traditional crops on a per-acre basis over the long term.
Frequently Asked Questions (FAQ)
- 1. What is the main difference between this Cassia (Tejpat tree) and the true Dalchini I hear about?
- The tree we are discussing, Cinnamomum cassia, provides both Tejpat (from leaves) and the thick, strong-flavoured bark commonly sold as Dalchini in India. True Cinnamon (Cinnamomum verum) is a different species with a milder flavour and is less suited for Bihar’s conditions. For commercial farming here, Cassia is the right choice.
- 2. How long do I really have to wait for the first income?
- You can expect the first bark harvest in the 4th or 5th year after planting. However, you can start earning from the 2nd year by smartly intercropping with crops like ginger, turmeric, or beans between the rows of young Cassia plants.
- 3. Can I grow Cassia on my small 1-acre family farm?
- Absolutely. Cassia is an excellent crop for smallholders. You can dedicate a portion of your land, say a quarter of an acre, to start with. It’s a low-volume, high-value crop, so you don’t need vast lands. Its ability to be intercropped makes it even more suitable for small farms.
- 4. Where can I get good quality Cassia saplings in Bihar?
- Start by contacting the Department of Horticulture, Bihar, your local Krishi Vigyan Kendra (KVK), or the Rajendra Prasad Central Agricultural University, Pusa. They can guide you to registered government or private nurseries that supply genuine, disease-free saplings.
- 5. My Cassia leaves are getting yellow spots and falling off. What should I do?
- This is likely a leaf spot or blight disease, common in humid weather. First, improve air circulation by removing weeds and any crowded lower branches. Collect and burn all fallen leaves to reduce the spread. As a control measure, you can spray a 1% Bordeaux mixture or a copper-based fungicide.
- 6. Is there a government subsidy for Cassia plantation in Bihar?
- Yes, spice cultivation, including Cassia, often falls under schemes promoted by the National Horticulture Mission (NHM). The Bihar government’s horticulture department regularly announces subsidies for planting material and establishment of new orchards. It’s essential to check with your district’s Horticulture Officer for the latest schemes and eligibility criteria.
Your Legacy in the Land
Cassia farming is more than just another agricultural venture; it is an act of foresight. It is about planting a tree whose shade you may not sit in immediately, but whose fragrant bark will provide for your family for decades.
