Mulberry (Shahtoot) Farming in Marathwada: Practical Step-by-Step Guide
Introduction
Mulberry (shahtoot) is a resilient, fast-growing perennial crop used for fresh fruit, leaf production for sericulture, and fodder. In Marathwada the key to success is matching variety and management to the region’s heat and erratic rainfall, and adopting water-efficient practices and timely pruning to maintain leaf quality and yield.
Site and Soil Requirements
Choose a site with deep, well-drained soil. Mulberry tolerates a wide pH range but performs best on neutral to slightly alkaline soils. Avoid waterlogged pockets; poor drainage causes root rot. If soil is shallow or stony, prepare raised beds or mounds and improve topsoil with organic matter.
Soil preparation
- Do a simple soil test for texture, pH and basic nutrients. Amend according to test results.
- In heavy soils, incorporate well-rotted farmyard manure or compost to improve structure and aeration.
- Dig planting pits 45–60 cm wide and deep in advance; keep the topsoil separate and mix with compost when backfilling.
Climate and Variety Selection for Marathwada
Marathwada has hot summers and variable monsoon rains. Select varieties that are heat-tolerant and fast-growing with good leaf quality. If the primary aim is sericulture, choose varieties preferred by local silk-reeling units. For fruit markets, select varieties known for fruit size and shelf life.
Propagation and Planting
Mulberry is commonly propagated by rooted cuttings, saplings or stooling. Rooted stem cuttings are economical and give uniform stands; nursery-raised saplings are easier for beginners.
Planting time
- Plant at the onset of the monsoon to take advantage of soil moisture, or in cooler months if irrigation is available.
Spacing and layout
- Spacing depends on purpose: closer spacing for leaf production and sericulture (e.g., high-density hedgerows), wider for fruit production and easier mechanisation.
- Design rows to allow sun and airflow; on sloping land, follow contours to reduce erosion and improve water infiltration.
Water Management and Irrigation
Water is the most critical constraint in Marathwada. Mulberry responds well to regular moisture for leaf growth but cannot tolerate prolonged waterlogging.
Efficient irrigation practices
- Install drip irrigation if possible: it saves water, keeps foliage drier (reducing disease risk), and allows fertigation.
- During establishment, irrigate frequently to promote rooting. Once established, lengthen intervals but avoid severe moisture stress.
- Use mulches to conserve soil moisture and suppress weeds—organic mulches also build soil organic matter.
Nutrient Management
Mulberry is a nutrient-demanding crop for rapid leaf turnover. Base fertiliser recommendations on soil test results; however, a practical programme includes balanced N, P and K with organic inputs.
Practical tips
- Incorporate well-rotted farmyard manure or compost annually around the root zone.
- Split nitrogen applications across the growing season to maintain leaf growth and avoid excess vegetative stretch before pruning.
- Use micronutrient sprays (iron, zinc) if deficiency symptoms appear—common in calcareous soils.
- With drip systems, apply fertilisers in smaller, frequent doses (fertigation) to match uptake.
Pruning, Training and Harvesting
Regular pruning keeps mulberry in a vegetative state with high-quality leaves. The pruning cycle and method depend on purpose (leaf vs. fruit).
Pruning system
- For leaf production, maintain multi-stemmed hedgerows or stools and cycle pruning every 45–90 days depending on growth rate and season.
- For fruit trees, develop a strong scaffold system and carry out annual maintenance pruning to open the canopy.
- Remove dead, diseased or crossing branches to improve airflow and reduce disease pressure.
Harvesting
- Harvest leaves in the early morning when turgidity is higher—this keeps leaf quality for silk worms or market sale.
- After pruning, leave a healthy stubble to produce new shoots quickly. Clean cuts and good sanitation prevent pathogen entry.
Pest and Disease Management
Monitor regularly and use integrated pest management (IPM) to minimise chemical use. Good cultural practices reduce most problems.
Common issues and on-farm remedies
- Leaf-eating caterpillars: scout leaves, handpick small infestations, or use biopesticides like Bacillus thuringiensis when necessary.
- Sucking pests (aphids, mealybugs): encourage natural enemies, use neem sprays or light soap-water sprays for small outbreaks.
- Fungal diseases (powdery mildew, leaf spot, root rot in waterlogged soils): ensure good drainage, avoid overhead irrigation, prune for airflow, and apply approved fungicides only when thresholds are exceeded.
- Root health: avoid waterlogging, rotate planting sites if possible, and use healthy planting material free from root pathogens.
Intercrops and Soil Conservation
Intercropping during the early years can improve income and soil health. Choose short-duration legumes or vegetables that do not compete heavily for water or light.
Soil conservation
- On slopes, build bunds or terracing and use cover crops to reduce erosion.
- Maintain organic cover and avoid over-cultivation near trees to protect fine feeder roots.
Post-harvest Handling and Marketing
Leaf quality is sensitive to handling and timing. For sericulture, deliver leaves quickly to the rearing units and avoid mixing leaves from different varieties when rearing sensitive silkworm races. For fresh fruit markets, handle gently, sort by quality, and supply to nearby markets or collection centres to reduce transport time.
Economics and Scale Considerations
Start with a demonstration block or a small area to learn local varietal responses, water needs and market links. Costs vary with planting density, irrigation setup and labour for pruning/harvest. Drip irrigation and mechanisation increase initial costs but reduce long-term labour and water use.
Seasonal Calendar (Practical Timeline)
- Pre-monsoon: site preparation, pit digging, install drip lines.
- Monsoon: plant saplings or cuttings, establish mulches, apply first organic manures.
- Post-monsoon/winter: low growth—focus on pest checks, training and corrective pruning.
- Spring/summer: main growth and leaf production—regular irrigation, split nutrients and harvesting cycles.
Practical Tips from Field Experience
- Use locally proven varieties: check with district agricultural office or neighbouring growers for what performs in Marathwada microclimates.
- Grow your own propagation material from healthy mother plants to cut costs and ensure uniformity.
- Keep simple records: planting dates, pruning dates, inputs, pest events and yields—this helps refine management year to year.
- Network with sericulture units or fruit traders before expanding to secure offtake and avoid gluts at harvest.
Conclusion
Mulberry can be a profitable and resilient crop in Marathwada when matched with the right variety, site preparation and water-efficient management. Start small, focus on soil health and irrigation, practice timely pruning and IPM, and build market connections. Practical adjustments to local conditions will be the deciding factor for long-term success.
