Mulberry Silkworm Farming in Chhattisgarh: Practical Step-by-Step Guide
Why sericulture in Chhattisgarh?
Chhattisgarh’s warm humid climate and long growing season suit mulberry cultivation and silkworm rearing. Smallholder farmers can integrate mulberry with existing cropping systems, using modest land and labour. The keys are reliable leaf supply, clean rearing conditions, and disciplined management at each stage of silkworm life.
Overview: two linked enterprises
- Mulberry cultivation — produce clean, nutritious leaves on a reliable schedule.
- Silkworm rearing — manage eggs, chawki (young) rearing, main rearing, mounting and cocoon harvest.
Site selection and soil for mulberry
Choose a site with good sunlight, protection from strong winds, and easy access to water. Mulberry tolerates a wide range of soils but performs best on deep, well-drained loams with good organic matter. Avoid waterlogged patches. If the native soil is poor, improve it by adding compost and well-decomposed farmyard manure.
Soil preparation
- Clear perennial weeds and level the site.
- Incorporate organic matter at 10–20 tonnes per hectare for established orchards; for small plots use compost or FYM in the planting hole.
- Plough or dig to loosen subsoil and ensure drainage; make raised beds where waterlogging is likely.
Planting mulberry: material and spacing
Use healthy planting material: grafted saplings or cuttings from productive mother plants (disease-free). For small farmers, rooted stem cuttings or saplings from a certified centre reduce initial risk.
Common layouts
- High-density hedgerow/row systems: single rows with close spacing encourage faster leaf harvest cycles.
- Planting distance depends on the variety and management: rows allow mechanical access and pruning; hedgerow systems optimise leaf plucking and regrowth.
Whichever layout you choose, maintain good plant hygiene: remove volunteer suckers from undesired places and mark each line for pruning schedules.
Nutrition and irrigation
Mulberry is a heavy feeder when managed for repeated leaf harvests. Combine organic inputs with balanced N-P-K based on soil test where available. Nitrogen supports leaf growth; apply it split across the season rather than all at once.
- Irrigate regularly during dry spells — leaves need steady moisture for quality foliage used by silkworms.
- Mulch reduces evaporation and suppresses weeds; organic mulch also improves soil health over seasons.
Pruning, leaf harvesting and scheduling
Good pruning practice establishes a predictable leaf calendar. Train plants for stems and basal shoots that allow multiple harvests per year.
- Prune to a uniform height and remove weak or diseased wood.
- Begin leaf harvesting once plants reach the required age/size and ensure young shoots are not overharvested.
- Schedule leaf plucking to match silkworm rearing cycles; young, tender leaves are critical for chawki rearing while more mature leaves can be used for later instars.
Establishing a silkworm rearing unit
Raising silkworms requires a clean, draft-free shelter with controlled temperature and humidity as much as possible. Even simple structures built from bricks or bamboo, with good ventilation and sun protection, will work if hygiene is enforced.
Basic layout
- Separate rooms or compartments for egg storage, chawki rearing, middle rearing and mounting.
- Raised rearing tables or racks for trays to reduce floor contamination and ease labour.
- Water source and hand-wash area near the rearing room to avoid bringing contaminants inside.
Silkworm basics: eggs to cocoon
Silkworm rearing breaks into clear stages. Maintain cleanliness and follow feeding schedules precisely.
1. Egg selection and incubation
- Obtain eggs from a reliable seed producer; choose healthy, disease-free batches.
- Store and incubate eggs at appropriate temperature and humidity recommended by the seed supplier; avoid wide fluctuations.
2. Chawki rearing (young worms)
Chawki silkworms (1st–3rd instars) are delicate and need the youngest, cleanest mulberry leaves. Feed frequently in small amounts to avoid leaf decay. Maintain strict hygiene: disinfect trays and tools and limit visitor access.
3. Middle and late rearing
As worms grow they consume large volumes of leaves. Shift them to larger trays or beds, increase feeding frequency, and monitor bowel movements (faecal build-up) to keep them on clean leaves. Ventilate carefully to control humidity and avoid temperature shocks.
4. Mounting and cocooning
- Provide suitable mountages (bamboo frames, branches, or commercial frames) near the end of the 5th instar when filtering behaviour begins.
- Avoid disturbance during cocoon formation; ill-timed handling causes poor cocoons or drop in silk quality.
Pests, diseases and sanitation
Prevention beats cure. Key practices are strict cleanliness, removing infected larvae or trays immediately, and avoiding contaminated leaves.
- Keep rearing rooms dry and ventilated; disinfect trays between crops using approved methods.
- Control common pests in mulberry: caterpillars, aphids and mites. Use integrated pest management — manual removal, neem-based sprays, beneficial insects and targeted chemical controls as last resort.
- Monitor for silkworm diseases: bacterial and viral outbreaks often follow poor sanitation or contaminated eggs/leaves. Quarantine new batches of eggs and seed cocoons when possible.
Harvesting cocoons and post-harvest handling
Harvest cocoons as soon as larvae finish spinning; delay invites predators and reduces cocoon quality. Sort cocoons to remove torn or brown-silk types that indicate disease or aborted spinning.
- Maintain a clean drying and storage area to keep harvested cocoons dry and free of mould.
- If selling to a cocoon market or cooperative, follow their packaging and quality grading requirements.
Yield factors and how to improve them
Yield per unit area or per silkworm batch depends on leaf quality, seed/existing stock quality, rearing hygiene, and management discipline. Focus on controllable factors:
- Consistent, high-quality tender leaves on schedule — plan mulberry pruning to match rearing cycles.
- Secure clean, certified eggs and follow incubation guidance.
- Strict rearing-room hygiene to prevent disease losses.
- Train labour in timely feeding and disturbance minimisation; human error is a major cause of losses.
Economics and market access
Before scaling up, calculate your input costs (land prep, planting material, labour for leaf harvesting and rearing, seed cocoons) against expected gross returns from cocoons or raw silk. Local sericulture extension centres, farmer cooperatives and state agencies in Chhattisgarh can advise on seed sources and market linkages.
Practical tips from growers
- Start small — use one or two rearing cycles to learn before expanding.
- Keep records: leaf production per bush, feed schedules, mortality rates and cocoon quality — data guide improvements.
- Neighbourhood cooperation for seed supply and bulk marketing improves bargaining power.
- Use organic soil amendments to build long-term productivity and reduce input shocks.
Step-by-step checklist to start
- Select site and prepare soil; establish water access.
- Obtain healthy planting material and plant using chosen layout.
- Build or adapt a clean rearing shed with basic sanitation facilities.
- Establish mulberry calendar: pruning, fertiliser and irrigation schedule.
- Source certified eggs; plan incubation and chawki rearing dates around leaf availability.
- Train workers on feeding frequencies, tray hygiene and mounting methods.
- Harvest cocoons carefully, grade and market through trusted channels.
Where to get help in Chhattisgarh
Reach out to state sericulture departments, local Krishi Vigyan Kendras (KVKs) and cooperative societies for training, certified seed cocoons and market information. Practical, hands-on training reduces early-season losses and builds confidence.
Final note
Sericulture ties agronomy and careful animal-like husbandry. Success in Chhattisgarh depends on reliable leaf supply, disease-free eggs, clean rearing, and disciplined schedules. Start conservatively, document each crop, and refine techniques season by season.
