Mulberry (Shahtoot) Farming in Kurnool: Practical Step-by-Step Guide
Why mulberry (shahtoot) in Kurnool?
Kurnool district has a semi-arid to sub-humid climate with a long dry season and a defined monsoon. Mulberry (shahtoot) performs well in warmer regions when you match variety, soil and water management. Mulberry is valuable for fresh fruit sales, processing and as a fodder/sericulture crop. This guide focuses on practical steps and low-risk practices for Kurnool growers.
Site and soil selection
Good sites for mulberry have:
- Deep, well-drained soils — loam to sandy loam preferred. Avoid waterlogged clay pockets.
- pH broadly between 6.0 and 8.0. If pH is outside this range, correct based on a soil test.
- Access to reliable irrigation. Mulberry needs moisture during growth and fruiting; dry spells at flowering reduce yields.
- Protection from extreme winds — windbreaks reduce branch breakage and fruit drop.
Variety selection
Do not plant on reputation alone. Choose varieties suited to your end use (fresh market, processing, sericulture) and local climate. Key points:
- White mulberry (Morus alba) is commonly used for fodder and sericulture and generally adapts to a range of soils.
- Black/purple-fruited types (Morus nigra and hybrids) are preferred for fruit markets but can be less vigorous in marginal soils.
- Check with the local Kurnool agricultural office or university station for proven local clones or improved strains and for source plant material free of pests and diseases.
Land preparation
Good land preparation establishes trees for long-term productivity:
- Clear previous vegetation and chisel or deep-plough the soil to break compaction if present.
- Mark rows with orientation that maximizes sunlight — typically north–south for even light distribution.
- Dig planting pits: common sizes are 45–60 cm wide and 45–60 cm deep depending on soil. For shallow soils, shallower but wider pits may be better.
- Backfill pits with a mix of topsoil, 5–10 kg well-rotted farmyard manure (FYM) and a handful of rock phosphate where available. Allow a week before planting if possible.
Planting layout and spacing
Spacing depends on intended system:
- For commercial fruit orchards: 4–6 m x 4–6 m spacing allows machinery access, crown development and better fruiting.
- For high-density production (short-term rotation or sericulture): closer spacing (2–3 m) with trained pruning can increase early yield but requires careful nutrient and irrigation management.
- Plant during the start of the monsoon or in cooler months with irrigation available for establishment.
Planting material and technique
Use healthy, disease-free saplings or rooted cuttings:
- One- or two-year-old grafted/vegetatively propagated plants establish faster with predictable traits.
- Plant so the graft union (if present) is above soil level. Firm the soil and water immediately after planting.
- Mulch around the base with 5–10 cm of organic material to conserve moisture and suppress weeds; keep mulch away from the trunk to avoid rot.
Irrigation and water management
Water is the single most limiting factor in Kurnool. Manage it carefully:
- Young plants need frequent watering to establish — keep the root zone moist but not waterlogged for the first 6–12 months.
- Mature trees need regular watering during leaf flush and fruiting. Monitor soil moisture; provide extra irrigation during dry spells and at flowering/fruit set.
- Mulberry responds well to drip irrigation — this saves water, keeps the canopy drier (reducing disease pressure) and delivers nutrients when fertigating.
Nutrition and fertilization
Get a soil test first; below are practical, commonly used approaches. Adjust to tree size, yield objectives and soil fertility:
- Apply well-rotted FYM or compost at 10–25 kg per tree annually during establishment, then 25–50 kg per tree for mature trees depending on soil organic matter.
- Split NPK applications through the year: apply more nitrogen during the active growing season, with phosphorus and potassium applied once or twice based on soil test. Local extension can supply recommended rates for tree age.
- Micronutrients (Zn, Fe, Mn) are often needed on alkaline soils; apply as foliar sprays based on deficiency symptoms or soil/leaf analysis.
Pruning, training and canopy management
Pruning shapes trees and maintains productivity:
- First 1–2 years: train a single trunk to a desired height (1.5–2.0 m) before encouraging scaffold branches.
- Annual pruning removes dead wood, opens the canopy to light and encourages new shoots that bear fruit. Moderate pruning stimulates new leaf growth for sericulture.
- For orchards, keep a balanced canopy with good internal airflow to reduce humidity-related diseases.
Pest and disease management
Common issues in the region and practical responses:
- Pests: mealybugs, whiteflies, aphids and some caterpillars. Monitor regularly and use neem-based or selective insecticides when economic thresholds are reached. Encourage natural enemies (ladybirds, lacewings).
- Diseases: powdery mildew and leaf spots can appear in humid spells. Improve airflow, avoid overhead watering late in the day, and use timely fungicide sprays if needed.
- Root rot: avoid waterlogging and plant on raised beds or well-draining soils. Remove and destroy badly infected plants.
- Adopt an IPM approach: regular scouting, proper nutrition and sanitation keep pesticide use low and effective.
Harvesting and post-harvest handling
Fruit quality and market timing matter:
- Mulberry fruits are perishable; harvest when fully colored and slightly soft. Harvesting in the cool part of the day preserves shelf life.
- Handle fruit gently — use shallow trays and avoid overstacking. Cool quickly after harvest if you can access cold storage or evaporative cooling to extend shelf life.
- Transport in small crates with cushioning to avoid bruising. For processing, coordinate harvest timing with processors to reduce losses.
Expected yields and returns
Yields depend on variety, tree age, management and water. Mature well-managed trees produce substantially more than young ones. For planning, use local extension estimates and your own pilot plots before scaling up. Keep records of inputs and yields so you can improve economics year to year.
Step-by-step seasonal calendar (practical)
- Pre-monsoon (Feb–May): prune, repair irrigation, apply basal FYM and conduct planting if you have irrigation.
- Monsoon (Jun–Sep): plant at start of rains if not done earlier, maintain weed control, monitor for pest outbreaks after heavy rains.
- Post-monsoon (Oct–Dec): fruiting and harvest periods for many varieties — manage harvest and post-harvest cooling; apply soil amendments.
- Winter (Jan–Feb): lighter watering, prepare for spring flush and conduct corrective pruning if required.
Common mistakes and practical tips
- Don’t skimp on water during establishment — survival is critical in year one.
- Avoid planting in low-lying spots that hold water; mulberry roots dislike prolonged saturation.
- Buy healthy, certified planting material to avoid introducing diseases.
- Keep good records: variety, planting date, fertiliser, irrigation, pests and yields. This makes improvement realistic and manageable.
- Start small and scale: test one block before committing large areas, especially if you plan to target fresh markets or processors.
Where to get local help
Consult Kurnool Krishi Vikas Kendras, state horticulture departments or local agro-extension officers for verified local varieties, nursery sources and specific fertilizer recommendations from soil tests. They can also advise on local market channels for fresh fruit and processing.
Final note
Mulberry (shahtoot) can be a reliable crop in Kurnool when you match variety, water and soil management to local conditions. Focus on sound nursery material, reliable irrigation, balanced nutrition, and regular scouting for pests and diseases. Start with a pilot block, keep simple records, and adjust practices based on your results and local extension advice.
