Mulberry (Shahtoot) Farming Guide for Gujarat Growers
Introduction
Mulberry (shahtoot) is a fast-growing fruit tree well suited to large and small holdings in Gujarat. It is grown for fresh fruit, shade, windbreaks and as a fodder/leaf crop for sericulture where applicable. This guide gives actionable steps tailored to Gujarat’s climate and soils—covering land selection, planting, maintenance, pest control and yield tips so you can plan and manage a productive mulberry orchard.
Climate and Varieties Suitable for Gujarat
Mulberry adapts to tropical and subtropical climates. In Gujarat, choose sites that avoid waterlogging and extreme coastal salinity. Summers are hot and winters mild—select varieties with heat tolerance and early fruiting. Popular types include white mulberry (Morus alba) and some locally selected hybrids that perform well under heat and moderate drought.
Variety selection tips
- Prioritise local acid- and heat-tolerant selections from district horticulture units or successful local orchards.
- For fruit production choose varieties known for larger berries and better taste; for leaf production (fodder/sericulture) choose varieties with prolific leaf flushes.
- Purchase grafted or budded plants from certified nurseries to ensure true-to-type and disease-free planting material.
Soil and Site Preparation
Mulberry grows on a range of soils but performs best on well-drained loam to sandy loam. Avoid heavy clay sites that retain water. Soil pH between 6.0 and 7.5 is ideal; it tolerates slightly alkaline soils too. Conduct a basic soil test before planting.
Land preparation
- Clear weeds and crop residues. Deep plough (25–30 cm) once to loosen compacted layers.
- If drainage is poor, consider raised beds or ridges to avoid root hypoxia during monsoon.
- Incorporate well-rotted farmyard manure or compost at 10–20 t/ha during final land preparation to improve structure and fertility.
- Mark plant spacing according to intended use (see next section).
Planting: Spacing, Time and Methods
Choose the planting season to avoid extreme heat and to allow establishment before the hot months—post-monsoon (September–October) or pre-monsoon (February–March) plantings work well.
Spacing
- For fruit orchards: 5 m x 5 m or 4 m x 5 m spacing gives room for canopy and management.
- For leaf/sericulture oriented systems: closer spacing such as 2 m x 2 m or 2 m x 3 m increases leaf yield but needs more intensive pruning.
Planting steps
- Dig pits 45–60 cm wide and deep. Allow pits to weather for a week if possible.
- Mix topsoil with 10–12 kg well-rotted manure and a handful of neem cake per pit; backfill partially.
- Plant grafted saplings carefully—do not bury graft union; firm the soil and irrigate immediately.
- Apply a light mulch around the base to conserve moisture and suppress weeds, keeping it away from trunk to avoid rot.
Irrigation and Water Management
Mulberry establishes quickly but young plants need regular moisture. After establishment the tree is moderately drought tolerant but productivity declines under prolonged water stress.
Irrigation schedule
- First year: frequent light irrigations every 7–10 days during dry spells to maintain steady soil moisture.
- Second year onward: irrigate every 10–15 days in hot, dry periods. Increase frequency in summer and reduce in monsoon.
- Drip irrigation is highly effective—saves water and improves yield by maintaining uniform moisture; consider one dripper per tree or two for wider spacings.
Nutrition and Fertiliser Management
Basal organic matter plus balanced NPK applications tailored by tree age will keep trees productive. Soil tests guide precise fertiliser rates.
General fertiliser guide
- At planting: 10–12 kg well-rotted FYM per pit.
- Young trees (1–3 years): apply nitrogen 50–100 g/tree/year split in 2–3 doses; phosphorus 25–50 g/tree/year and potassium 25–50 g/tree/year.
- Mature trees: increase nitrogen to 200–400 g/tree/year depending on growth and leaf removal; split doses aligned with new flushes (pre-monsoon and post-monsoon).
- Use organic options like compost and green manures where possible to build soil health. Apply micronutrients if deficiency symptoms appear (chlorosis, poor growth).
Pruning, Training and Canopy Management
Pruning is essential: it encourages regular flushing for leaves and simplifies harvesting of fruits. Training in early years sets a manageable structure.
Practical pruning tips
- First year: select 3–4 strong scaffolds and remove competing shoots to form a central framework.
- Annual pruning: after harvest or during dormant mild winter months perform light pruning to shape canopy and remove dead or crossing branches.
- Coppicing and pollarding: for leaf production, regular cutting back (every 6–8 months) stimulates multiple shoots and high leaf yield.
- Sanitation pruning: remove diseased or pest-infested wood promptly to limit spread.
Pest and Disease Management
Mulberry is prone to common pests: mealybugs, scales, aphids, and nematodes; diseases include powdery mildew, root rot and leaf spot. Early detection and integrated measures work best.
IPM checklist
- Maintain good airflow by pruning and avoid dense canopies to reduce fungal diseases.
- Use neem oil or soap sprays for minor infestations of aphids and mealybugs; follow label instructions for rates and pre-harvest intervals.
- Encourage natural enemies: ladybugs, lacewings and parasitic wasps by avoiding broad-spectrum insecticides when possible.
- For root rot, ensure good drainage and avoid excess irrigation. Replace heavily infested plants and treat soil if necessary.
- Rotate or interplant with non-host crops in new plantings to reduce soil-borne pest buildup.
Harvesting and Post-harvest Handling
Mulberries are delicate and perishable. Harvest when fully ripe for best flavor but handle gently.
Harvest tips
- Pick in the cool hours (early morning) to reduce heat stress and maintain fruit firmness.
- Use shallow trays and avoid stacking fruit to prevent bruising.
- Sort and cool produce quickly if selling fresh; for processing (jam, juice, drying) harvest at peak ripeness depending on product specifications.
Expected Yields and Economic Notes
Yields depend on variety, spacing, management intensity and irrigation. Mature trees in well-managed orchards can produce substantial fruit and leaf yields.
Grower-oriented expectations
- Fruit orchards: a well-managed mature tree may yield tens of kg of fruit per season; orchard-level yields vary widely with spacing and care.
- Leaf harvest systems for fodder/sericulture: frequent cuts can produce high cumulative leaf biomass per hectare; close spacing and coppicing increase per-hectare yields but require intensive labour.
- Plan costs: initial establishment (land prep, planting material, irrigation) is front-loaded. Recurring costs include labour for pruning and harvest, fertiliser and pest management.
Practical Recommendations for Gujarat Growers
- Start small: trial a block of 0.5–1 ha to learn local variety responses before scaling up.
- Invest in drip irrigation and mulching—this pays off in water savings and steadier yields under Gujarat’s hot climate.
- Keep detailed records of fertiliser, irrigation, pruning dates and pest events to refine practices year to year.
- Network with local extension services or experienced mulberry growers for variety recommendations and market connections.
Conclusion
Shahtoot (mulberry) can be a resilient and rewarding crop in Gujarat when matched to the right site, variety and management. Focus on good planting stock, appropriate spacing for your end-use, water-efficient irrigation and routine pruning. With these practical steps you can establish a productive orchard and adapt practices based on local experience and market needs.
