Introduction
Mace, known locally as javitri, is the red aril surrounding the nutmeg seed. In Manipur’s humid subtropical climate, mace can be grown successfully where soils are well drained and shade and moisture are managed. This guide focuses on pragmatic steps from site selection through to harvest, post-harvest handling and selling—targeted to smallholders and farmers wanting to add a high-value spice to diversified farms.
Why consider mace in Manipur?
Mace is a spice with good demand in domestic and export markets. It fits agroforestry and multi-storey systems, grows alongside fruit trees and provides a long-term income stream once trees establish. In Manipur, the climate is generally suitable where frost is absent and drainage is adequate.
Variety and planting material
Choose healthy, grafted or seedling material from a reliable source. Seedlings avoid grafting costs but show genetic variability in yield and quality. If available, select superior clones or grafts known for good aril coverage and nut size.

Site selection and soil
- Climate: Mace prefers warm, humid conditions without frost. Protected valleys and lower hill slopes in Manipur are suitable.
- Soil: Deep, well-drained loamy soils with good organic matter are best. Avoid waterlogged heavy clays. Slightly acidic to neutral pH works well.
- Topography: Gentle slopes are preferable for drainage. Wind protection helps protect young trees and arils during harvest season.
Land preparation
Clear weeds and perennial grasses. Dig planting pits of about 60 x 60 x 60 cm and mix topsoil with compost or well-decomposed farmyard manure. If soil is poor, add 2–5 kg compost per pit and a handful of rock phosphate for phosphorus.
Planting layout and spacing
- Standard spacing is 8–10 m between trees to allow crown development and intercropping. In home gardens or mixed systems, 6–8 m can be used if management is intensive.
- Planting density will depend on spacing—leave space for intercrops (banana, shade-tolerant vegetables) during the early years.
- Plant at the onset of the rainy season to reduce irrigation needs for establishment.
Nursery management
Raise seedlings in a shaded nursery bed or polybags with a well-draining potting mix. Harden seedlings for several weeks before transplanting. For grafted plants, use disease-free rootstock and experienced grafters.
Watering and shade
Young trees need regular watering in the first 2–3 years. Mace trees appreciate partial shade during establishment; provide shade with temporary shade nets or intercrop with fast-growing leguminous trees that can be removed later.
Fertiliser and soil health
- Apply organic manure annually—well-decomposed farmyard manure or compost at planting and as a top dressing.
- Basal application of rock phosphate and potash where soil tests show deficiencies. If a soil test is available, follow recommended doses; otherwise apply moderate amounts and monitor tree health.
- Minor nutrients like magnesium and zinc can be applied based on deficiency symptoms (yellowing, poor growth).
- Mulch around the base to retain moisture and suppress weeds, but keep mulch away from direct stem contact to avoid rot.
Pruning and training
Form a strong scaffold by pruning in the early years to encourage a single central leader and well-spaced branches. Remove dead or crossing branches and maintain an open canopy to improve light penetration and air circulation.

Pest and disease management
- Pests: Fruit flies can affect fruit; use traps and field sanitation. Stem borers and leaf-eating caterpillars are occasional; hand-pick and spot-treat with recommended insecticides if necessary and safe for local use.
- Diseases: Leaf spots and root rot can occur in poorly drained soils. Ensure good drainage and avoid waterlogging. Treat fungal problems with appropriate fungicides and remove infected material.
- Practice field sanitation—collect and destroy fallen fruits and debris to reduce disease inoculum and pests.
Intercropping and agroforestry
During the initial years, intercrop with short-duration crops like vegetables, pulses or banana to optimise land use and provide income. Keep competition for water and nutrients in check and remove intercrops as tree canopy closes.
Flowering, fruiting and harvesting
Nutmeg trees usually begin fruiting after several years depending on planting material and management. Monitor trees during the fruiting season. Harvest when fruits begin to split open—this indicates mature nuts.
- Collect fruits promptly from the tree or ground to avoid deterioration.
- Separate the mace (red aril) from the shell carefully; the aril is the product. Work soon after harvest while the aril is still pliable and brightly coloured.
Post-harvest handling: processing and drying
Proper handling preserves quality and market value.
- Washing: Gently wash arils in clean water to remove dirt.
- Drying mace (javitri): Spread arils thinly under shade to dry slowly, or use indirect hot-air drying if available. Drying should remove moisture reliably without burning; final texture should be brittle and the colour should be pale orange to light yellow depending on drying method. Avoid direct strong sun which darkens colour and reduces aroma.
- Drying nutmeg seeds: The inner nut (seed) is often dried and sold as nutmeg; dry seeds for several weeks until the kernel rattles inside its shell when shaken.
- Storage: Store dried mace in airtight, moisture-free containers in a cool, dark place. Protect from insects and strong odours.
Grading and quality
Grade mace by colour, thickness and cleanliness. Bright, evenly coloured, clean pieces fetch better prices. Remove discoloured or mouldy pieces before packing.

Packaging and marketing
- Smallholders can start by selling cleaned and dried mace to local spice traders, processors or exporters. Establish links with buyers through local markets and cooperatives.
- If aiming for higher returns, consider bulk packing in moisture-proof bags, maintaining traceability (farm source, harvest date) and meeting buyer quality specifications.
- Explore value addition: whole dried mace, ground mace, or hygienically packed small consumer packs can access retail markets but require equipment and food-safety compliance.
Record-keeping and economics
Keep simple records of planting dates, inputs (manure, fertiliser, pesticides), labour and harvest. Mace is a long-term crop—initial years require investment in establishment but trees provide returns over many years. Consider grouping with neighbours for collective marketing to access better prices and reduce transaction costs.
Common practical tips for Manipur growers
- Avoid low-lying plots prone to waterlogging—root rot is a common cause of failure.
- Protect young trees from strong winds and grazing by livestock.
- Do not allow arils to sit on the ground for long; collect and process quickly to prevent rot and insect damage.
- Use locally available organic materials for mulch and compost to improve soil organic matter gradually.
- Link with state agriculture extension or spice boards for technical support and market information.
Conclusion
Mace (javitri) can be a valuable niche spice crop for growers in Manipur when established on well-drained sites and managed for soil health, timely harvesting and careful drying. Start small, learn post-harvest handling practices that keep colour and aroma, and build buyer contacts before expanding. With patience and good management, mace trees become a steady component of diversified farming systems.
