How to Grow Mulberry (Shahtoot) in Guntur: Complete Guide
Why grow mulberry (shahtoot) in Guntur?
Guntur district’s climate — hot summers, mild winters and a defined monsoon — suits mulberry (Morus spp.) well for both fruit and leaf (sericulture) production. Mulberry is hardy, quick to establish, and responds well to irrigation and nutrient management. This guide is written for growers who want practical, field-tested steps to establish and manage productive shahtoot blocks in the Guntur agro-ecology.
Choose the right variety
Selecting the correct variety is the single most important decision. For Guntur, consider whether your primary goal is fruit (fresh market) or leaf (silkworm rearing):
- Fruit varieties: Locate varieties known locally for larger berries and good taste. These often produce attractive fresh-market fruit and can be sold directly at local markets.
- Leaf/sericulture varieties: If the goal is to supply mulberry leaves for silk production, choose varieties selected for high leaf yield, tender foliage and quick regrowth after pruning.
- Talk to local agricultural extension or sericulture offices to obtain disease-free planting material adapted to the area.
Site selection and soil
Mulberry grows on a range of soils but performs best on deep, well-drained loams with good fertility. In Guntur:
- Avoid waterlogged fields; trees will tolerate short water stress but not prolonged saturation.
- pH between 6 and 7.5 is ideal; slightly alkaline soils common in the region are acceptable with organic matter.
- Choose a site with full sun; shade reduces leaf and fruit production.
Land preparation
Prepare the land before planting to ensure a fine tilth and good drainage:
- Clear weeds and crop residues; plough to 30–40 cm where possible to break hardpans.
- Add well-decomposed farmyard manure (FYM) or compost at 10–20 tonnes per hectare during final land prep for new plantations.
- Mark beds and planting lines based on chosen spacing (see next section).
Planting time and spacing
Best planting time in Guntur is at the end of the monsoon or early winter so young plants establish before the hot season. For spacing:
- For fruit orchards: 4–5 m between trees and 5–6 m between rows is common to allow canopy development and mechanisation or manual access.
- For high-density leaf plantations for sericulture: 1.5–2 m x 1.5–2 m spacing or even closer with hedgerow/row systems to facilitate frequent pruning and leaf harvesting.
- Adjust spacing to your labour, irrigation systems and end-use (fruit vs. leaves).
Planting technique
- Use healthy, disease-free saplings or cuttings. Rooted cuttings or grafted saplings generally establish faster than seedlings.
- Dig holes about 45–60 cm wide and deep. Mix topsoil with FYM/compost and a handful of rock phosphate if available.
- Plant so the root collar is at ground level; firm the soil and irrigate immediately.
- Mulch around the base with organic material to conserve moisture and suppress weeds.
Irrigation and water management
Mulberry responds well to regular moisture, especially during establishment and fruiting. In Guntur:
- Install drip irrigation where possible for efficient water use and fertigation. Alternatively, use furrow or basin irrigation depending on layout.
- Keep young plants moist for the first 6–12 months; reduce frequency but maintain steady supply in hot months.
- For bearing trees, schedule irrigation more frequently during fruit development to avoid fruit drop and bitter flavour.
- Monitor soil moisture; avoid prolonged waterlogging which causes root decline.
Nutrition and fertilization
Mulberry is a heavy feeder. Use a balanced program combining organic matter and fertilizers:
- Apply FYM or compost annually in established orchards — 10–20 kg per tree per year for fruit trees, more for intensive leaf systems.
- Fertilizer programs depend on tree age: give lower doses to young trees and increase as trees mature. A commonly used approach is split applications of nitrogen through the growing season with phosphorus and potassium applied after each harvest cycle or seasonally.
- Consider soil and leaf testing to fine-tune rates. Micronutrients (zinc, iron, boron) may be needed on deficient soils; apply as foliar sprays if deficiencies appear.
Pruning, training and canopy management
Pruning manages tree size, encourages new shoots for leaf harvest, and improves fruit quality:
- For fruit trees: train to 3–4 main scaffolds with a clear central leader in the first 2–3 years. Prune to open the canopy and improve sunlight penetration.
- For leaf production (hedge or pollard systems): regular coppicing or pollarding at set heights encourages tender shoot regrowth. A 6–8 week cutting cycle is typical under intensive production.
- Remove dead, diseased and crossing branches annually. Conduct heavier pruning in winter or immediately after main harvest periods.
Pest and disease management
Common issues in Guntur include pests like mealybugs, aphids, caterpillars and diseases such as powdery mildew, leaf spot and root rot in poorly drained soils. Integrated management steps:
- Maintain tree vigour with proper nutrition and irrigation; healthy trees resist pests better.
- Monitor regularly; hand-pick large caterpillars and remove infested material.
- Use biological controls (neem oil, insecticidal soaps, Trichogramma for caterpillars) where effective and permitted.
- Apply fungicides only after identification and where necessary. Avoid routine sprays; follow label guidance and local advice.
- Sanitation: remove and burn or bury heavily infected plant parts to reduce inoculum.
Harvesting and post-harvest handling
Harvest timing depends on use. For fresh fruit, pick when berries are fully colored, soft and easily detach. For leaf harvest, timing is based on shoot age:
- Fruit: Harvest carefully to avoid bruising. Handle in shallow containers and cool quickly if possible. Market fresh fruit promptly as mulberries are perishable.
- Leaf: Harvest tender leaves and shoots for silk rearing. Keep leaves clean and free from sprays that could harm silkworms.
- Stagger harvests by selecting varieties and pruning schedules to supply a steady flow of produce or leaves.
Intercropping and farm integration
Young mulberry blocks can host short-duration intercrops (legumes, vegetables) for the first 1–2 years until canopy closes. Intercropping adds income and fixes nitrogen if legumes are used. Avoid deep-rooted or competitive crops once trees mature.
Economics and market tips
Plan sales before planting: know local demand for fresh fruit vs leaves. For sericulture, link with local silk producers for steady off-take. For fresh fruit, focus on quality, cleanliness and quick transport to markets. Consider value-adds like jam or dried fruit where feasible.
Practical checklist for first year
- Select adapted variety and obtain healthy planting material.
- Prepare land, add compost/FYM and improve drainage.
- Plant at the recommended spacing; mulch and irrigate regularly.
- Set up drip irrigation if possible and plan a fertiliser schedule.
- Monitor pests/diseases and establish pruning regime before canopy closure.
Final tips from growers
Talk to neighbouring mulberry growers in Guntur — local experience will tell you which clones resist heat, which pruning intervals give the best leaf quality for silk, and which markets pay well for fruit. Start small, keep good records of inputs and returns, and scale once you have a reliable routine.
Mulberry is a flexible crop for Guntur farmers: with careful variety choice, water management and pruning you can produce profitable fruit or high-quality leaves for sericulture. Focus on establishment, regular monitoring and timely interventions for best results.
