PB 1509 Paddy Basmati

PB 1509 is a notified Basmati paddy variety for the Kharif season — a semi-dwarf, 115–120 day crop with long, slender Basmati grain. ICAR puts its maturity at 115 days, about 30 days earlier than PB 1121; in PAU trials it ripens about 95 days after transplanting.

PB 1509 is the early basmati: it frees the field in time for wheat and saves 3–4 irrigations compared with PB 1121 (ICAR). It is susceptible to bacterial leaf blight, so keep nitrogen low. It is transplanted later than PB 1121 and with younger seedlings — follow the dates below, not the PB 1121 calendar.

Land and sowing window

• Season: Kharif, transplanted; fits rice–wheat, rice–potato and other multiple-cropping rotations
• Soil: loamy soils with low permeability are best; rice tolerates pH 5–9
• Punjab (PAU): nursery sowing in the second fortnight of June; transplanting in the second fortnight of July
• Haryana, Delhi, Western UP (IARI): nursery 15–30 June; transplant about 25-day-old seedlings in the second week of July onward
• Why not earlier: early transplanting pushes grain filling into the heat and spoils cooking quality; it also exposes the crop to more stem borer and disease

How to sow

• Seed rate: about 4–5 kg per acre of nursery seed (IARI practice; one 4 kg pack per acre); PAU advises up to 8 kg of heavy, water-sorted seed per acre
• Nursery: about 160 sq m (6.5 marla) for one acre; sow sprouted seed thinly
• Seed treatment: treat the seed before nursery sowing — Trichoderma asperellum 2% WP at 15 g per kg (and a 6-hour seedling root dip at 15 g per litre before transplanting) against foot rot, or carbendazim + mancozeb 75 WS at 3 g per kg (PAU)
• Seedling age: about 25 days — PAU specifically asks for 25-day-old seedlings of PB 1509 for better tillering
• Spacing: 20 cm × 15 cm (33 hills per sq m), 2 seedlings per hill, 2–3 cm deep; 15 × 15 cm if transplanting late
• Pack size: 4 kg

Manure and fertiliser (per acre)

• Basal dose: phosphorus and potash only as per soil test, before the last puddling — no basal urea for basmati (PAU). If the field has been green manured with dhaincha or sunnhemp, give no urea at all
• Nitrogen: 54 kg urea per acre for PB 1509 (PAU), top-dressed in two equal splits at 3 and 6 weeks after transplanting, when water is not standing; irrigate on the third day
• Phosphorus (P₂O₅): skip if the previous wheat got its recommended dose; in deficient soils 75 kg single superphosphate (about 12 kg P₂O₅), or DAP and other macro and micronutrients as per your soil test
• Zinc: 25 kg zinc sulphate heptahydrate (21%) or 16 kg monohydrate (33%) at puddling where the field has shown deficiency
• Because the plant is short, it makes less biomass than tall Basmati types — it does not need more nitrogen to make up for it

Water, weeds and pests

• Irrigation: keep water ponded for 2 weeks after transplanting, then irrigate two days after the ponded water has soaked in. No stress at flowering; stop irrigation about 15 days before harvest. The short duration is what saves 3–4 irrigations
• Weeds: timely weed control — pre-emergence herbicide as a sand mix within 2–3 days of transplanting (e.g. pretilachlor 50 EC 600 mL or pendimethalin 30 EC 1–1.2 L per acre), or bispyribac-sodium 10 SC 100 mL per acre at 20–25 days. Rotate herbicide groups
• Stem borer: spray at 2% dead hearts; prefer neem (azadirachtin 5%, 80 mL per acre) at pest start, then advisory-approved insecticides as per label
• Leaf folder and planthoppers: leaf folder at 10% leaf damage; planthoppers at 5 per hill (tap plants weekly from a month after transplanting). Avoid synthetic pyrethroids — they flare up hoppers
• Diseases: scout for blast (leaf spots at tillering, neck rot at ear emergence) and foot rot; PB 1509 is susceptible to bacterial leaf blight — disease-free seed, no excess nitrogen, no nitrogen after 6 weeks, no continuous ponding. Spray only as per label and your state advisory

Harvest

• Duration: 115–120 days seed to seed; about 95 days after transplanting (PAU) — usually mid to late October, in time for wheat
• Stage: as soon as the ears are nearly ripe and the straw turns yellow; thresh the same or next day to protect head-rice recovery
• Plant: semi-dwarf (about 92 cm, PAU), with less straw biomass
• Grain: long slender Basmati grain that nearly doubles on cooking

Crop practices follow state agricultural university recommendations for North India; confirm doses for your district with your Kern dealer or KVK.

अक्सर पूछे जाने वाले सवाल

PB 1509 की नर्सरी और रोपाई कब करें?

नर्सरी 15–30 जून और रोपाई 15–31 जुलाई, लगभग 25 दिन की पौध से। PB 1121 वाले कैलेंडर से न बोएं।

एक एकड़ में कितना बीज लगेगा?

लगभग 4–5 किग्रा प्रति एकड़ — 4 किग्रा का 1 पैक 1 एकड़ के लिए (PAU: 8 किग्रा भारी बीज)।

कितना यूरिया डालें?

54 किग्रा यूरिया प्रति एकड़, रोपाई के 3 और 6 सप्ताह बाद दो बराबर हिस्सों में; बेसल यूरिया नहीं।

PB 1121 के मुकाबले पानी कितना बचता है?

कम अवधि के कारण PB 1121 से 3–4 सिंचाई कम लगती हैं।

फसल कितने दिन में पकती है?

बीज से बीज 115–120 दिन, रोपाई के लगभग 95 दिन बाद — गेहूं की बुवाई के लिए खेत समय पर खाली।
