Growing Shahtoot (Mulberry) in Solapur: Practical Guide
Overview and why mulberry (shahtoot) fits Solapur
Shahtoot (mulberry) is a flexible crop that adapts well to hot, semi-arid plains when given reliable irrigation. In Solapur district its advantages are quick establishment, multiple uses (fresh fruit, processed products, fodder and mulberry leaf for sericulture), and low shelter requirements. To succeed you must manage soil moisture, choose the right planting material, and be proactive on pests and pruning.
Climate and soil requirements
Mulberry tolerates a wide temperature range but prefers warm conditions for good fruit set and growth. Solapur’s hot summers and mild winters are suitable if you manage water and protect young plants from extreme heat during establishment.
- Temperature: growth is best in 20–35°C range; young plants need shade or extra water during heat waves.
- Rainfall & irrigation: natural rainfall is erratic in Solapur. Mulberry needs supplemental irrigation—especially in the first 2–3 years and during fruiting.
- Soil: deep, well-drained loamy soils are ideal. Mulberry tolerates slightly alkaline soils common in the region; avoid waterlogged sites.
- pH: generally performs well in pH 6.0–8.0.
Varieties and planting material
There are many species and cultivars; for Solapur the practical choice is between white mulberry (Morus alba) for high yields and suitability for sericulture and black/red types (Morus nigra/rubra) when fruit quality and flavour are priorities. Choose planting material based on your market—fresh fruit buyers, processors or leaf for feed.
- Propagation: hardwood cuttings and root suckers are the quickest and most reliable methods for farmers. Grafted or budded saplings give uniform fruiting behaviour and are recommended if available.
- Cuttings: use 40–60 cm hardwood cuttings taken in dormant season, with 2–3 buds each. Plant in well-prepared pits and keep moist.
- Nursery saplings: raise in polybags for 6–8 months before outplanting; harden off 2–3 weeks before transplant.
Planting layout and spacing
Spacing depends on intended use.
- Fruit orchard: 4–6 m between plants and 5–6 m between rows (approx. 350–625 trees/ha). This allows good canopy development and fruit picking.
- Serriculture / leaf production: closer spacing (1.5–2.5 m) and frequent coppicing to produce young leaves.
- Fodder hedges: planting in rows with 1–1.5 m spacing and regular cutting.
Land preparation and planting steps
- Land preparation: plough and remove perennial weeds; level the field for uniform irrigation.
- Pits: dig pits 60 x 60 x 60 cm in heavy soils, smaller in lighter soils. Mix topsoil with well-rotted farmyard manure (FYM) or compost.
- Planting time: best at onset of monsoon (June–July) to utilise rainfall; in irrigated blocks planting in October–November also works.
- Planting method: place sapling/cutting so that the root collar is at soil level, backfill gently and water immediately. Mulch to conserve moisture.
Irrigation and water management
Water is the limiting input in Solapur. Mulberry responds well to frequent, controlled watering especially during establishment and fruiting.
- Establishment (first year): keep soil consistently moist—irrigate every 7–10 days in hot weather, less during rains.
- Young trees (2–3 years): reduce frequency but maintain deep wetting to encourage root growth; irrigate every 10–15 days when dry.
- Mature trees: during active fruiting irrigate every 7–12 days depending on soil and weather. Reduce in winter.
- Irrigation methods: drip irrigation is highly recommended for water economy and better yield; if using floods, level the field and use basins around trees.
- Mulching with straw, cane trash or shredded leaves reduces evaporation and improves water use efficiency.
Nutrition and fertiliser guidance
Mulberry has a moderate nutrient demand. Start with organic matter and supplement with balanced NPK based on tree age and vigour.
- At planting: incorporate 10–12 kg well-rotted FYM or compost per pit.
- Young trees: apply split doses of nitrogen to encourage leafy growth, combined with single applications of phosphorus and potassium annually. Observe tree vigour and adjust dose.
- Mature fruit trees: follow soil test recommendations where possible. Apply fertilizers in split doses—half at bud break and half during fruit development—and ring-apply or fertigate under drip lines.
- Micronutrients: watch for deficiency signs (chlorosis, poor fruit set) and apply targeted sprays or soil applications as needed.
Training, pruning and canopy management
Pruning shapes trees for light penetration, controls size for easy harvesting, and stimulates new shoots for fruiting.
- Formative pruning (years 1–3): select 3–4 strong scaffolds and remove competing leaders to create an open vase or central leader as preferred.
- Maintenance pruning: annual pruning after harvest to remove deadwood, improve airflow and stimulate new shoots; moderate heading back to keep trees manageable.
- Coppicing: in leaf-production systems, coppice trees 1–2 times per year to harvest leaves; trees regrow vigorously if well-fertilized and irrigated.
Pest and disease management (practical approach)
Integrated Pest Management (IPM) is the best strategy: monitor regularly, maintain tree health, use biological controls and apply chemicals only when thresholds are crossed.
- Common pests: leaf-eating caterpillars, mealybugs, aphids and thrips can occur. Regular scouting and washing leaves with water or neem-based sprays helps reduce populations.
- Diseases: leaf spots and fungal blights appear in humid conditions. Ensure good air circulation by pruning, avoid overhead irrigation late in the day, and remove infected material.
- Sanitation: remove fallen, diseased leaves and old prunings. Healthy trees withstand pest pressure better.
- Biocontrols and botanicals: encourage natural enemies (ladybirds, parasitic wasps), and use neem oil or biopesticides as first-line treatments. Follow local extension guidance for chemical controls and registered products.
Harvesting and post-harvest handling
Harvesting depends on variety and market. Mulberries are perishable and bruise easily—handle with care.
- Yield timing: fruiting often starts in the second or third year and peaks in subsequent years.
- Picking: pick when fully coloured and slightly soft; harvest during cooler parts of the day to reduce spoilage.
- Post-harvest handling: sort and cool quickly. For fresh market pack in shallow trays or punnets; for processing, cool and transport to processors promptly.
- Processing options: value-added routes include jams, squashes, dried berries and wine—explore local processors or cooperative arrangements if fresh-market returns are low.
Marketing and economics (practical tips)
- Know your market before planting—fresh market demands good-quality, uniform fruit; buyers often prefer black or dark-red varieties for better colour.
- Cooperatives and farmer groups can improve bargaining power for processing contracts or bulk sales.
- Diversify income: use trees for fruit, sell prunings as fodder, or combine leaf production with sericulture where feasible.
Common mistakes and how to avoid them
- Underestimating water needs: Solapur’s climate requires planned supplementary irrigation—don’t rely on erratic rains.
- Poor plant material: avoid mixed or untested seedlings; buy from reputable nurseries or use healthy cuttings.
- Neglecting pruning: untrained trees become tall and difficult to harvest and manage.
- Poor post-harvest handling: mulberries are delicate; quick cooling and gentle packing increase marketable returns.
Final checklist before you start
- Decide the primary purpose: fresh fruit, processing, fodder or leaf for sericulture.
- Source uniform, healthy planting material (prefer grafted varieties if available for fruit uniformity).
- Plan irrigation (prefer drip) and mulch setup to conserve water.
- Set up a pruning and pest scouting calendar for the first 3 years.
- Secure market: identify buyers or processors before large-scale planting.
Mulberry can be a resilient and profitable crop in Solapur when grown with attention to irrigation, planting material and practical canopy management. Start small, learn from the first cycles, and scale up once you establish reliable water, labour and market links.
