How to Grow Mulberry (Shahtoot) in Uttarakhand
Why grow mulberry in Uttarakhand?
Mulberry (shahtoot) fits well into many parts of Uttarakhand. It grows on gentle slopes and terraces, tolerates a range of soils, provides fast returns from leaf harvests and timber, and supports sericulture and livestock fodder. For smallholders, mulberry can be integrated into agroforestry systems, orchards and riparian protection belts.
Climate and site selection
Choose sites with good drainage—mulberry does not tolerate waterlogged soils. In Uttarakhand you can grow mulberry from the low hill plains up to mid-hill elevations where frost is not severe for extended periods. Protect young plants from hard winter frost and late spring frosts that can damage new leaves.
- Aspect: South- or southeast-facing slopes give earlier leaf flush; north-facing slopes extend leaf retention in hot seasons.
- Drainage: Avoid valley bottoms that remain wet. Terraces with a slight slope work best.
- Wind: Provide windbreaks on exposed ridges; strong wind tears leaves and reduces yields.
Soil and land preparation
Mulberry is adaptable but performs best on fertile, deep, well-drained loams. Prepare the field ahead of planting:
- Plough or hoe to loosen the soil to at least 30–40 cm to encourage root spread.
- Dig planting pits (45–60 cm cube) in hard or shallow soils and backfill with a mix of topsoil and well-rotted farmyard manure.
- If soils are acidic (common in some hill areas), apply lime based on a soil test; otherwise a light application of wood ash can help.
Varieties suitable for Uttarakhand
Choose varieties based on end-use: leaf quality for silkworm rearing, fruit, or timber. In India, there are improved sericulture varieties and local hill types. For Uttarakhand:
- Use improved, locally tested varieties where available—these tend to have good leaf yield and regrowth after pruning.
- Local hill or hardy strains are valuable on poorer, shallow soils as they tolerate stress better.
- For fruiting/edible mulberry, select cultivars known for sweet fruit and market acceptance in nearby towns.
Propagation methods
Two practical methods for smallholders:
- Stem cuttings: The fastest and cheapest. Use hardwood cuttings 30–40 cm long with 2–3 nodes. Plant directly in the field at an angle or in a nursery bed. Protect from drought until established.
- Rooted saplings: Raise in polythene bags or nursery beds from cuttings or layers and transplant after 4–6 months when 30–60 cm tall. Handle roots carefully during transplanting.
Planting layout and spacing
Spacing depends on system and end-use:
- For leaf production (frequent pruning): 2.5–3 m between plants and 3–4 m between rows to allow machinery and manual access.
- For fruiting or timber: wider spacing of 4–6 m supports larger trees.
- On terraces, plant along the contour to reduce erosion and facilitate irrigation.
Water management
Mulberry needs regular moisture during establishment and at times of active shoot and leaf growth. In hill areas where irrigation water is limited:
- Apply frequent, light irrigations rather than infrequent heavy watering—this encourages surface rooting suitable for terraces.
- Mulch with straw or green material to conserve soil moisture and suppress weeds.
- In monsoon, ensure good drainage to avoid root rot; in dry months, irrigate to maintain leaf quality if growing for silkworms.
Fertilizer and nutrient management
Base nutrient inputs on the tree age and soil fertility. Practical guidance without soil tests:
- At planting: mix a generous quantity of well-rotted farmyard manure or compost into each pit.
- Young trees (first 2–3 years): apply balanced NPK at light rates and supplement with FYM annually to build soil organic matter.
- Mature plantations: split nitrogen applications to encourage leaf flushes; monitor leaf colour and vigour and adjust fertiliser accordingly.
Pruning and training
Pruning determines leaf yield and tree form. Two common systems:
- Coppice system (for leaves/sericulture): Cut trees down to 30–40 cm stumps at specific intervals (frequency depends on climate and variety) to encourage multiple shoots and frequent leaf harvests.
- Standard tree training (for fruit or timber): Form a strong scaffold with 3–4 main branches and manage canopy for air and light. Prune dead and crossing branches annually.
Timing: Prune in early spring before new growth starts; avoid heavy pruning just before cold spells.
Pest and disease management
Common problems in hill conditions include leaf spots, powdery mildew, mealybugs, aphids and root rot where drainage is poor. Integrated measures work best:
- Sanitation: Remove and burn severely infected leaves or shoots. Keep the plantation weed-free.
- Cultural: Improve air circulation by judicious pruning and avoid overhead irrigation when possible.
- Biological and low-toxicity controls: Use neem oil or soaps for sap-sucking pests, and encourage natural enemies (ladybirds, lacewings).
- Chemical options: Reserve selective insecticides or fungicides for serious outbreaks and follow label rates. For sericulture growers, coordinate treatments to avoid harming silkworms.
Intercropping and farm integration
Mulberry works well with other enterprises:
- Intercrop with short-season vegetables or legumes during the first years to keep soil covered and add income.
- Understorey fodder: Grow shade-tolerant fodder species to feed livestock.
- Agroforestry: Combine mulberry with nitrogen-fixing trees on wider spacings to improve soil and provide timber or fuelwood.
Harvesting and post-harvest
Leaf harvests depend on pruning cycle and purpose. For silkworm feeding, timing and leaf quality are critical—remove older, coarse leaves and harvest young flushes. Handle leaves carefully to avoid bruising if using for fresh markets.
For fruit, pick when fully ripe and use gentle handling and quick transport to local markets. Timber is a longer-term product and requires planned thinning and selective harvesting.
Marketing and value chains
Decide your primary market before committing to a planting system: fresh leaf markets, silkworm rearers, fruit markets, fodder buyers, or timber. Key tips:
- Build relationships with sericulture units or local traders early—regular buyers prefer consistent quality and timing.
- Drying leaves for winter fodder or selling processed products (jams, syrups) can add value if local demand exists.
- Group marketing through farmer groups can reduce transport costs and improve bargaining power.
Economics and scale
Start small and learn the crop on your specific site before expanding. Monitor labour needs for pruning and leaf harvests—mulberry can be labour intensive during peak periods. Where possible, integrate mulberry with other farm activities to spread risk and labour.
Practical tips for hill growers in Uttarakhand
- Trial a few varieties on small blocks across different exposures to find best-performing material on your slopes.
- Protect young plants from livestock browsing with simple fencing; mulberry regrows well after browsing but repeated damage slows establishment.
- Use terracing and contour planting to reduce soil erosion and concentrate moisture where roots can access it.
- Keep records of pruning dates, leaf harvests, and pest outbreaks—this practical data is more valuable than general recommendations when decisions are needed for your farm.
Where to get support
Contact local Krishi Vigyan Kendras (KVKs), the state horticulture or sericulture department, and extension agents for planting material and locally tested recommendations. Farmer groups and existing sericulture units can provide immediate practical tips and market contacts.
Conclusion
Mulberry is a flexible crop for Uttarakhand farmers when selected and managed to fit local slopes, soils and markets. Start with good site preparation, choose suitable planting material, focus on water management and pruning, and use integrated pest management. With careful planning, mulberry can supply leaf, fruit, fodder and timber while fitting into smallholder farm systems.
