HD 3471 (NICRA Pusa Wheat 3471)

HD 3471 (NICRA Pusa Wheat 3471) is an improved bread-wheat variety developed by ICAR-Indian Agricultural Research Institute (IARI), New Delhi, with HD 3086 as the improved background. It is targeted primarily for irrigated, timely-sown wheat production in the North-Western Plains Zone (NWPZ) — India's largest and most productive wheat-growing zone, with approximately 12.33 million hectares under wheat.

🌱 Detailed Package of Practices (General Wheat Cultivation)

Note: The TDF document for HD 3471 does not list variety-specific package of practices. The points below are standard irrigated timely-sown wheat cultivation practices compiled from ICAR-IIWBR / Vikaspedia for reference.

🌡️ Climate & Soil

Wheat is a cool-season crop; optimum temperature for germination is 20–25°C, for tillering 16–20°C, and for grain filling 20–25°C. It grows best in well-drained loam to clay loam soils with a pH range of 6.0–7.5. For irrigated timely-sown conditions (as recommended for HD 3471), sowing should be completed by the first fortnight of November in the NWPZ.

🚜 Land Preparation

Prepare the field with 2–3 harrowings followed by planking to obtain a fine, clod-free seedbed. Retain adequate soil moisture at sowing. Incorporate 5–6 t/ha of well-decomposed FYM during the final ploughing.

🌾 Seed Rate & Seed Treatment

Seed rate: 100 kg/ha for timely-sown irrigated wheat (higher seed rate of 125 kg/ha is used for late sowing).

Seed treatment: Treat seed with Carboxin 37.5% + Thiram 37.5% @ 2 g/kg or Vitavax @ 2 g/kg to protect against loose smut and seed-borne diseases. For termite-prone areas, treat with Chlorpyriphos 20 EC @ 4 ml/kg seed.

Sowing: Sow in rows 20 cm apart at a depth of 5 cm using a seed drill or by the pora method.

🧪 Manures & Fertilizers

FYM: 5–6 t/ha incorporated during land preparation.

Recommended fertilizer dose: 150 kg N, 60 kg P₂O₅ and 40 kg K₂O per hectare for irrigated timely-sown wheat.

Application: Apply half of N and full P & K as basal at sowing. The remaining N is top-dressed in two equal splits — at first irrigation (CRI stage, 20–25 DAS) and at second irrigation (tillering stage, 40–45 DAS). Apply zinc sulphate @ 25 kg/ha if soil is deficient in zinc.

💧 Irrigation

Irrigated wheat requires 4–6 irrigations depending on soil type and rainfall. Critical stages for irrigation:

• CRI (Crown Root Initiation) stage — 20–25 DAS (most critical)
• Tillering stage — 40–45 DAS
• Late jointing/booting stage — 60–65 DAS
• Flowering stage — 80–85 DAS
• Milk stage — 100–105 DAS
• Dough stage — 115–120 DAS

Irrigate lightly at each stage, ensuring no water stagnation.

🧑‍🌾 Intercultural Operations

Weed control: Apply pre-emergence herbicide Pendimethalin @ 1.0 kg a.i./ha within 2–3 days of sowing. For post-emergence control, spray Sulfosulfuron @ 25 g a.i./ha at 30–35 DAS. One hand weeding at 30–35 DAS may be needed.

Earthing up: Not commonly required for wheat, but light hoeing may help in heavy soils.

🛡️ Plant Protection

Major pests: Aphids, termites, and pink stem borer.

• Aphids: Spray Dimethoate 30 EC @ 1 ml/litre or Imidacloprid 17.8 SL @ 0.3 ml/litre
• Termites: Apply Chlorpyriphos 20 EC @ 4 ml/kg as seed treatment
• Pink stem borer: Apply Carbofuran 3G @ 25 kg/ha at the base of plants

Major diseases: Yellow/stripe rust, brown/leaf rust, loose smut, and powdery mildew.

• Rusts: HD 3471 carries resistance genes (Yr2, Lr13+10+, Sr13+7b+) offering protection. In case of susceptible check varieties, spray Propiconazole 25 EC @ 1 ml/litre at first appearance
• Loose smut: Carboxin seed treatment
• Powdery mildew: Spray Wettable Sulphur @ 2 g/litre

🧺 Harvesting

Wheat matures in about 140–150 days after sowing for timely-sown varieties. Harvest when the crop turns golden yellow, grains become hard, and moisture content drops to 14–16%. Combine harvesting or manual harvesting followed by threshing is practiced. Store grain at 10–12% moisture in clean, dry bins.

📦 Post-Harvest Management

Clean, dry and grade the grain before storage. Store in airtight containers or warehouses to prevent insect infestation. Use of neem leaves or fumigants may help in long-term storage.

📈 Market & Commercialization Potential

🎯 Target Geography

Punjab, Haryana, Delhi, Rajasthan (excluding Kota and Udaipur divisions), western Uttar Pradesh (excluding Jhansi division), Kathua district of Jammu & Kashmir, Una district and Paonta Valley of Himachal Pradesh, and the Tarai region of Uttarakhand.

Punjab, Haryana and western UP alone account for approximately 9.3–9.5 million ha of wheat cultivation — a major initial market.

🥇 Competitive Positioning

HD 3471 is positioned as a potential alternative to widely cultivated varieties such as HD 2967, DBW 187, PBW 826 and HD 3086. It offers enhanced yield potential along with resistance to major rust diseases, providing a more diversified genetic basis for disease management.

💰 Farmer-Level Economic Benefits

With a reported potential yield of 74.6 q/ha and average yield of 60.19 q/ha, HD 3471 offers scope for incremental yield advantage. Additionally, resistance to yellow/stripe and brown/leaf rust can reduce crop losses and fungicide expenditure, strengthening its value proposition.

📊 Potential Area Adoption (Years 1–5)

🌱 Seed Multiplication & Demand

Breeder seed demand is expected to exceed 100 quintals from the Department of Agriculture and Cooperation (DAC) in the first year. Subsequent demand will depend on foundation and certified seed production, distribution arrangements, farmer adoption and the number of seed companies participating.

🤝 Proposed Licensing Terms

The proposed strategy is to enter into agreements with approximately 100–150 seed firms, covering micro, small, medium and large enterprises, to accelerate seed multiplication and facilitate rapid dissemination to farmers.

🌍 Anticipated Social Impact

HD 3471 is expected to generate significant social benefits by improving productivity, production stability and resilience to rust diseases. Its higher yield potential can contribute to increased farm income, particularly for small and medium farmers. Reduced disease losses and lower fungicide expenditure will decrease production risk and promote sustainable crop management. Wider adoption will diversify the varietal base of wheat, strengthen resilience against evolving pathogen populations, and generate employment through seed production, processing, certification and distribution. At the broader level, increased and more stable wheat production will contribute to regional food security and availability of staple food grains.

💰 Technology Developmental Cost

Total cost required to complete this innovation: ₹3,82,62,870/- (Rupees three crore eighty-two lakh sixty-two thousand eight hundred and seventy only), including manpower, equipment, raw material and all other resources. Intellectual cost has been considered.
