Sesame (Sesamum indicum) — called तिल (Til) in Nepal — is one of humanity's oldest oilseed crops and a critical income crop for smallholder farmers in Nepal's Terai and inner Terai regions. Sesame seeds are rich in oil (50–55%), protein (25%), and minerals including calcium, magnesium, and iron. In Nepal, sesame is used in traditional sweets (laddu, chikki), religious offerings, and cold-pressed sesame oil (तिलको तेल).
Quick Answer: Sesame is sown in Shrawan (July–August) in Nepal and harvested in Kartik (October–November). Seed rate is 5–6 kg per hectare with 30×10 cm spacing. Avoid waterlogged soils.
Why Grow Sesame in Nepal? (तिल किन लगाउने?)
Sesame is uniquely suited to Nepal's Terai farming systems. As a warm-season kharif crop, it fits between two major rice-wheat rotations, making it excellent for intensification without land expansion. It is drought-tolerant, requires minimal water, and fetches premium prices in both domestic and export markets.
- Total sesame area in Nepal: ~50,000 hectares (concentrated in Eastern and Central Terai)
- Average yield: 0.6–0.8 t/ha nationally; improved varieties can yield 1.2–1.5 t/ha
- Market price (2024): NPR 120–180 per kg for cleaned sesame seed
- Revenue potential: NPR 72,000–108,000 per hectare — significantly higher than maize
- Export market: Nepal exports sesame primarily to India, Japan, and the Middle East
- Traditional significance: Essential for religious festivals (Maghe Sankranti, Tihar) — assured domestic demand
Best Sesame Varieties for Nepal (तिलका जातहरू)
Nepal grows both traditional local varieties and improved varieties developed by NARC. The entity 'sesame variety' has attributes of seed color (white, black, brown), oil content, maturity duration, and yield — and these values differ significantly between local and improved types.
| Variety | Nepali Name | Seed Color | Duration (days) | Yield (t/ha) | Characteristics |
|---|---|---|---|---|---|
| Local (स्थानीय) | स्थानीय | Mixed | 90–100 | 0.5–0.7 | Adapted, seed available locally, lower yield |
| Krishna (कृष्ण) | कृष्ण | Black | 85–95 | 0.8–1.0 | Black seed, good oil content, disease resistant |
| Til-1 (NARC) | तिल-१ | White | 80–90 | 1.2–1.5 | Highest yield, improved variety, buy certified seed |
| Til-2 (NARC) | तिल-२ | White/Brown | 85–95 | 1.0–1.3 | Suitable for Terai and inner Terai |
White-seeded varieties like Til-1 command premium prices in international export markets. Black sesame (Krishna variety) is preferred for religious and traditional markets domestically. Farmers growing for export should use NARC-certified improved white varieties.
Sesame Farming Calendar (तिल बाली क्यालेन्डर)
| Activity | Nepali Month | English Month | Action |
|---|---|---|---|
| Land preparation | Ashadh (असार) | June–July | Fine tilth, field leveling, drain if needed |
| Sowing | Shrawan (श्रावण) | July–August | Line sowing at 30×10 cm, 5–6 kg seed/ha |
| Thinning | Shrawan | July–August | Thin to 1 plant per 10 cm at 2-week stage |
| Weeding (1st) | Shrawan–Bhadra | August | Remove weeds at 3–4 weeks after sowing |
| Fertilizer top-dress | Bhadra (भदौ) | August–September | Urea top-dress at branching stage |
| Weeding (2nd) | Bhadra–Ashwin | September | Second weeding + earthing up |
| Harvest | Kartik (कार्तिक) | October–November | Harvest when lower capsules begin to split |
Seed Rate and Planting Method (बीउ दर र रोप्ने तरिका)
Sesame seeds are extremely tiny — 1 gram contains approximately 350–500 seeds. This means very small quantities of seed cover large areas. Precise sowing is critical to achieve proper plant population without thinning.
- Seed rate: 5–6 kg per hectare (5-6 केजी प्रति हेक्टर)
- Mix seed with fine dry sand (1:10 ratio) for uniform broadcasting or line sowing
- Row spacing: 30 cm (row to row)
- Plant spacing: 10 cm (plant to plant within row)
- Sowing depth: 1–2 cm — sesame is extremely sensitive to deep sowing
- Optimum plant population: 300,000–350,000 plants per hectare
Soil and Water Requirements (माटो र पानी)
Sesame is a drought-tolerant crop — one of its primary advantages over rice and maize. However, it is critically sensitive to waterlogging. This is the most important soil management rule for sesame in Nepal.
"पानी जमेको ठाउँमा नलगाउने।" — Do not plant sesame in waterlogged areas. This traditional Nepali farming principle is the single most important rule for sesame cultivation. Standing water for even 24–48 hours can kill sesame plants at any growth stage.
- Ideal soil: Sandy loam, well-drained, pH 6.0–7.5
- Water requirement: MEDIUM — 300–400 mm total (compared to rice's 1,200–2,000 mm)
- Monsoon moisture is usually sufficient for Shrawan-sown sesame in Terai
- Do NOT sow in fields that collect standing water
- Ensure adequate drainage channels (नाला) around sesame fields before sowing
Fertilizer Management for Sesame
Sesame has moderate nutrient requirements. Over-fertilization — especially excessive nitrogen — causes excessive vegetative growth and reduced seed production.
| Fertilizer | Amount (kg/ha) | Timing | Notes |
|---|---|---|---|
| FYM / Compost | 3,000–5,000 kg | 2–3 weeks before sowing | Improve soil structure |
| DAP | 60–80 kg | Basal at sowing | Phosphorus promotes root development |
| Urea | 80–100 kg | Split: 50% basal + 50% at branching | Avoid excess N |
| Muriate of Potash | 30–40 kg | Basal at sowing | Improves oil content |
| Sulphur | 20–25 kg | Basal | Critical for oil quality in sesame |
Pest and Disease Management (कीरा र रोग नियन्त्रण)
- Sesame Webworm (Antigastra catalaunalis): Ties leaves with webbing and feeds inside — at early infestation spray a registered insecticide such as Dimethoate, at the dose on its label
- Leaf Roller / Bud Fly (Asphondylia sesami): Causes bud galling — remove and destroy affected buds
- Alternaria Leaf Spot (Alternaria sesami): Brown spots on leaves — spray Mancozeb or Carbendazim
- Phytophthora Blight: Stem rot at soil level — caused by waterlogging — prevent by ensuring drainage
- Cercospora Leaf Spot: White spots with dark margins — spray Copper Oxychloride
Crop Rotation for Sesame
Sesame fits well into Nepal's standard Terai rotation systems. It serves as an excellent short-duration cash crop between rice and wheat seasons.
- Rice → Sesame → Wheat: Less common because of timing overlap, but possible with early rice varieties
- Maize → Sesame (secondary crop): After early maize harvest, sesame fits as a second crop before Rabi season
- Fallow → Sesame → Wheat: Best when field was in fallow — sesame improves soil tilth
- Sesame after Dhan: Possible in Terai if rice harvest is early (Mangsir) — immediately followed by sesame sowing
Harvest, Threshing, and Storage
Sesame harvest timing is critical. Because capsules shatter easily when fully dry — spilling seeds — harvest must occur when capsules are just beginning to turn yellow and the lower-most capsules start to crack. This is a window of 2–4 days in typical Terai weather.
- Harvest indicator: 75% of capsules have turned yellow, lower capsules begin to split
- Harvest method: Cut plants at base, bundle, and stand upright in the field for 7–10 days to finish drying
- Threshing: Beat dried bundles against a threshing board over a clean mat to collect seeds
- Cleaning: Winnow to remove chaff; avoid high-moisture environments during storage
- Storage moisture: Dry to below 6% moisture for safe long-term storage
- Packaging: Use clean, dry sealed bags — sesame absorbs odors from nearby materials
Track Your Sesame Crop with Krishi Patro
The Krishi Patro app includes sesame (तिल) in its full crop calendar — aligned with Nepal's Bikram Sambat calendar. Farmers can check sesame's sowing and harvest months and see weather alerts for their district — useful in Terai districts like Morang, Sunsari, Saptari, and Siraha, where sesame is an important cash crop.
If you grow sesame for export quality (white seed, clean grain), use Krishi Patro to track harvest date precisely. Late harvest means capsule shattering and seed loss; early harvest means low oil content and lower market price.
