Why grow raw (green) banana in Bihar?
Raw or green banana (often sold for cooking, snacks, and processing) fits well in Bihar’s subtropical climate and mixed cropping systems. It provides steady income, fits into smallholder farms, and can be planted on a range of soils if managed properly. This guide focuses on practical steps you can use on-farm in Bihar.
Choose the right variety
Select a variety adapted to local conditions and market demand. Key options for raw/processing use in Bihar include:
- Basrai/Basirhat – commonly used for cooking in the region; sturdy pseudostem and good bunch formation.
- Grand Naine (Dwarf Cavendish) – popular for both green fruit and table use; easy to manage and high packing quality.
- Rasthali/Champa – acceptable for local markets and tolerant of varied soils.
Check with your local KVK or agricultural extension for the newest locally tested clones and tissue-cultured planting material availability.
Site selection and soil requirements
Banana grows best where:
- There is full sun and protection from strong, drying winds (use windbreaks if needed).
- Soils are deep, well drained and rich in organic matter. Heavy clay can be used but ensure drainage beds or raised planting to avoid waterlogging.
- pH is near neutral (5.5–7.0). Acidic soils respond well to lime application.
Land preparation and planting
Prepare land by ploughing and adding well-decomposed farmyard manure or compost (5–10 kg per pit or per plant area depending on system). Use pits or raised beds if waterlogging occurs.
- Planting time: In Bihar, planting after the onset of monsoon is common, but with assured irrigation you can plant year-round.
- Spacing: For bunch production aim for 2.5–3.0 m between rows and 2.0–2.5 m between plants (about 1,300–2,000 plants per hectare depending on layout). For tighter, management-intensive systems use 2.5 x 2.5 m.
- Depth: Dig pits around 45–60 cm wide and 45 cm deep if using pits. Mix topsoil with compost and a handful of rock phosphate or bone meal where available.
- Planting material: Use healthy suckers (preferably sword suckers 6–12 months old) or tissue culture plants. Remove loose soil from suckers, trim roots to encourage new growth, and plant at same depth as in nursery.
Water management
Banana is a thirsty crop. Key practices:
- Keep soil evenly moist; avoid water stress during vegetative growth and bunch formation.
- Irrigation frequency: In monsoon, natural rainfall may be enough; in dry months provide supplemental irrigation weekly or more often depending on soil type and plant size. Sandy soils require more frequent watering.
- Use basin irrigation or drip where possible. Drip irrigation saves water and allows targeted fertigation.
Nutrient management
Banana responds to regular nutrient supply. A simple guideline for smallholders:
Latest Articles
- Apply well-decomposed cow dung or compost at planting. Keep a mulch of organic matter around plants to conserve moisture and feed soil life.
- Split nitrogen applications: more during early growth and just before flowering. Use urea or organic sources; combine with FYM/compost to improve efficiency.
- Ensure potassium availability: bananas require relatively high potassium for good bunch growth; apply muriate of potash according to soil test or extension advice.
- Apply zinc and magnesium if deficiency symptoms (chlorosis, stunted leaves) appear. Foliar sprays can correct minor deficiencies quickly.
Soil testing is the best way to plan fertilizer rates—consult your nearest soil testing lab or extension office.
Intercrops and crop protection
Banana plantations benefit from mulching and intercrops. Short-duration legumes (cowpea, groundnut) in the early phase add nitrogen and cover soil. Keep the immediate base free of competing plants to reduce pest habitat.
Pest and disease management
Focus on prevention and field hygiene:
- Pseudostem borer and rhizome borers: Remove and destroy infected plants. Avoid injuring the corm during planting and cultural operations.
- Nematodes: Use resistant planting material where possible and practice crop rotation, sanitation, and organic amendments to reduce populations.
- Panama disease/Fusarium wilt and Black Sigatoka: Use clean planting material and resistant varieties; remove and destroy affected plants; avoid reuse of contaminated soil or tools.
- Sigatoka and leaf spots: Maintain good aeration by proper spacing and removal of old leaves; use fungicides only when needed and follow label instructions.
Keep tools clean, remove infected plant debris promptly, and avoid water movement from infected to healthy blocks.

Cultivation and bunch management
- Desuckering: Keep 1–2 healthy suckers per mat—one main crop and one reserve to replace the mother plant. Remove other excess suckers regularly.
- Propping: For heavy bunches or tall varieties, provide props to prevent toppling. Use wooden poles or cement posts and tie the pseudostem above the second or third leaflet.
- Bunch covering: Use perforated polythene or paper covers to protect fruit from pests, sunburn and improve appearance for markets. Ensure adequate ventilation in covers to avoid heat buildup.
Harvesting and post-harvest handling
Harvest green bananas when hands in the middle of the bunch are plump and regularly sized, depending on variety and market requirements. For raw banana market, fruit are usually harvested green but physiologically mature.
- Cut the whole bunch with a sharp knife and handle gently to avoid bruises.
- Transport in shaded, clean crates. Avoid stacking heavy loads on top of ripe or mature bananas.
- For ripening, store at appropriate temperatures or sell direct as green fruit to processors and local vendors.
Marketing and value addition
Green bananas have demand in kitchen markets, processing units (banana flour, chips), and local wholesale markets. Practical tips:
- Identify buyers before harvest—local mandis, processors, restaurants, and bulk vendors of raw banana chips.
- Grade and pack to buyer specifications. Clean bunches and remove dead leaves to improve price.
- Consider value addition: chips, dehydrated slices, or simple processing can increase returns if there is local demand and processing know‑how.
Common on-farm problems and quick fixes
- Yellowing leaves in young plants: Check for waterlogging, root rot, or nutrient deficiency (nitrogen/magnesium). Improve drainage and apply balanced fertilizer.
- Pests in corms or pseudostem: Inspect regularly; remove infested plants and burn or bury deep.
- Poor bunch formation: May be due to inadequate potassium or irregular water during flowering—correct nutrient program and irrigation schedule.
Final practical checklist before planting
- Source healthy, disease-free planting material—preferably from trusted nurseries or KVKs.
- Prepare soil and pits with compost and correct pH if needed.
- Plan irrigation and mulching strategy; consider drip for water efficiency.
- Arrange for props and bunch covers and know your buyers or markets in advance.
Banana cultivation rewards attention to detail—regular removal of infected plants, balanced nutrition, and consistent water supply will give reliable green fruit for local markets. Start with a small block, learn local variety performance, and scale up once you have experience with local pests, soils and buyer preferences.
