Growing Shahtoot (Mulberry) in Vidarbha: Practical Guide
Why mulberry (shahtoot) in Vidarbha?
Mulberry (shahtoot) suits Vidarbha’s tropical to semi-arid climate when you match variety and management to local conditions. It provides fruit for fresh/small-scale processing markets and is the primary feed for silkworms (Morus alba). With the right clone, soil and water management, mulberry establishes fast and gives reliable returns on small holdings.
Site and soil
Choose a site with:
- Full sun exposure — mulberry needs good sunlight for fruiting and leaf production.
- Well-drained soils. Mulberry tolerates a range of soils from light sandy to heavy clay but performs best on fertile loams with good internal drainage.
- pH around 6.0–7.5. Avoid waterlogged spots — prolonged waterlogging leads to root rot.
For gently sloping fields, plant on contour or terraces to reduce erosion and conserve moisture. If salinity is an issue, select tolerant clones and avoid low-lying saline pockets.
Varieties and selections
Mulberry for Vidarbha is used in two main ways: fruit production and leaf production for sericulture. Key considerations:
- Morus alba (white mulberry) is commonly used for silkworms and is fast-growing with abundant leaves.
- Morus nigra and Morus rubra and their selections produce darker, more flavourful fruits for fresh markets but may have different growth habits.
- Local or improved clones adapted to Vidarbha’s heat and drought are preferable — consult your local Krishi Vigyan Kendra (KVK) or state sericulture department for the best clones and planting material.
Propagation and planting material
Propagation methods:
- Softwood or semi-hardwood cuttings: the simplest and most reliable on most soils when planted at the start of the rainy season.
- Suckers and root-cuttings: commonly used and effective for producing uniform plants.
- Grafting/budding: used to combine desirable fruiting scions on hardy rootstocks where specific fruit types are required.
Raise planting material in a well-prepared nursery for 4–6 months until 30–45 cm tall. Harden plants before transplanting.
Land preparation and planting
Prepare pits or beds ahead of planting, preferably before the monsoon:
- Pit size: about 45–60 cm cubical where soils are poor; backfill with topsoil mixed with well-rotted farmyard manure (FYM) or compost.
- Spacing: for fruit orchards use 3 × 3 m to 5 × 5 m depending on variety vigour and mechanisation. For leaf/sericulture blocks, closer spacing (e.g., 2 × 2 m) or hedgerow systems are common to maximize leaf yield and ease of harvest.
- Planting time: start of monsoon (June–July) is ideal in Vidarbha to ensure good establishment; in irrigated situations you can transplant outside the rainy season if irrigation is available.
Irrigation and water management
Mulberry responds well to regular moisture during establishment and leaf expansion:
- Establishment: keep soil moist for the first 2–3 months — weekly deep wetting is better than frequent light watering.
- Later years: irrigate according to season and crop use. For fruiting trees, supply water during fruit set and development. For leaf production, frequent irrigations during hot dry spells maintain leaf quality and quantity.
- Use drip irrigation where possible to save water and deliver nutrients efficiently; mulch to conserve soil moisture and moderate soil temperature.
Nutrition and fertilizer
Mulberry responds to organic matter and balanced fertilisation:
- At planting: incorporate 10–20 kg well-rotted FYM/compost per pit.
- Young trees (first 1–2 years): apply modest amounts of nitrogen to encourage leaf and shoot growth, split across the growing season.
- Mature trees: management depends on target (leaf vs fruit). Regular light nitrogen applications encourage leaf growth for sericulture; balanced NPK and micronutrients support fruiting. Where soil tests are available, tailor fertilizer rates to soil nutrient status.
- Top-dress with FYM or compost annually and consider foliar micronutrient sprays (e.g., zinc, iron) if deficiencies appear.
Pruning and training
Pruning controls form, improves light penetration and eases harvest:
- Formative pruning: in the first 1–2 years select 3–4 scaffold branches to form a strong framework; remove weak shoots and competing leaders.
- Annual pruning: tailor to end use. For fruit trees, moderate pruning after harvest improves next season’s flowering. For leaf production, coppicing or pollarding systems are used — cut back to a stump/height to encourage multiple leafy shoots for regular leaf harvests.
- Sanitation pruning: remove dead, diseased or infested wood promptly to reduce pest/disease carryover.
Pests and diseases — practical control
Common problems in Vidarbha include insect pests and fungal diseases. Manage them with integrated practices:
- Pests: caterpillars (leaf rollers/borers), aphids, mealybugs and jassids can reduce leaf quality. Monitor regularly, use pheromone or light traps where available, conserve natural enemies, spray neem or approved insecticides only when thresholds are reached.
- Diseases: powdery mildew and leaf rust occur in humid spells; ensure good air circulation through pruning, avoid overhead irrigation at night, and apply recommended fungicides when necessary.
- Root rot: avoid waterlogging and use healthy planting material; fungicide dips for high-risk soils are sometimes used.
- IPM: combine cultural controls (sanitation, proper spacing), biologicals (Bt for caterpillars, predatory insects) and targeted chemical interventions as a last resort.
Harvesting and post-harvest
Harvest timing depends on end use:
- Fruit: pick when fully ripe and coloured for the selected variety. Handle gently — mulberries bruise easily. Cool quickly if selling fresh, and sell quickly to local markets or retailers.
- Leaves for sericulture: harvest tender leaves as required by the rearing schedule; maintain continuous leaf supply by staggering pruning/coppicing dates across the block.
- Post-harvest handling: keep fruit shaded and cool; short shelf life means marketing close to harvest is essential. For leaves, store in cool, moist conditions and transport immediately to rearing houses.
Yields and economic notes
Yields vary widely with variety, plant age, irrigation and management. Mature mulberry trees under good management can produce sizeable leaf bulk for silkworms or fruits suitable for fresh sale or processing. Plan enterprise economics based on local market prices and input costs; small-scale trials on a few plots will give reliable local data before larger investments.
Intercropping and farm integration
Mulberry can be integrated into mixed farms:
- Intercropping during the establishment years with short-duration crops helps maintain income and soil cover.
- Hedgerow or live-fence systems provide leaves and additional benefits like wind protection.
- Combine mulching with on-farm compost production to improve soil organic matter and reduce fertilizer costs.
Practical tips for Vidarbha growers
- Start small and select clones recommended by local extension services or KVKs — local adaptability is key in hot-dry Vidarbha conditions.
- Prioritise water conservation: mulching, contour planting and drip irrigation pay dividends in dry spells.
- Plan leaf harvest cycles or fruit marketing channels before planting — market access determines variety choice and management intensity.
- Keep records of planting dates, pruning, fertiliser and pest events; these help refine practices season-to-season.
- Join farmer groups or sericulture cooperatives where available — collective marketing and bulk inputs help small growers.
Where to get help
Contact your local Krishi Vigyan Kendra (KVK), state sericulture department or agricultural university extension agent for location-specific clone recommendations, nursery sources and current pest control advisories. Local demonstrations and farmer field schools are particularly valuable for hands-on techniques like coppicing systems and leaf harvest scheduling.
With correct clone choice, water-wise management and consistent pruning and nutrition, shahtoot can become a dependable component of a Vidarbha farm — whether your aim is fresh fruit, processing or silkworm leaf production.
