Growth Stages

1

Seedling

2-3 weeks

Single cotyledons emerge; primary leaves unfold with distinctive compound leaflet structure

Keep soil consistently moist but not waterlogged. Ensure full sunlight exposure. Thin seedlings if overcrowded.

2

Vegetative Growth

6-8 weeks

Plant develops bushy branching habit with pinnate leaves; semi-determinate growth pattern

Provide rhizobium inoculant support for nitrogen fixation. Apply phosphorus fertilizer. Monitor for pests. Light pruning encouraged for compact growth.

3

Flowering

3-4 weeks

Small yellow to orange flowers appear in terminal and axillary clusters; plant reaches mature height of 1.5-2 meters

Maintain consistent watering during this critical period. Avoid high nitrogen fertilizer which promotes leaf growth over flowers. Support with staking if necessary in windy areas.

4

Pod Development & Fruiting

6-8 weeks

Flowers mature into distinctive oblong, beaked pods containing 3-5 seeds each; pods develop greenish to brown coloration

Reduce watering frequency as pods mature. Continue monitoring for pod borers and other pests. Ensure good air circulation to prevent fungal diseases.

5

Maturity & Harvest

2-3 weeks before harvest

Pods dry to brown color, rattle when shaken; seeds reach their full hard texture; plant begins senescence

Allow pods to mature fully on plant for maximum yield. Harvest when pods are completely dry. Store dried seeds in cool, dry conditions.

Avoid planting near:

Other annual legumes that may compete for nitrogen fixation Crops requiring intensive nitrogen fertilization (which suppresses pigeon pea nodulation) Plants susceptible to similar pests (Helicoverpa species)

Common Pests

  • Use pheromone traps, neem spray, or Bacillus thuringiensis (Bt) biopesticide; release natural predators like parasitic wasps

  • Spray with insecticidal soap or neem oil; prune affected plant parts; ensure adequate irrigation

  • Use sticky yellow traps; spray with neem oil or insecticidal soap; maintain plant vigor through proper watering

  • Remove and destroy affected stems; use crop rotation; apply neem-based insecticides

  • Manual removal of infested leaves; neem spray; maintain good field sanitation

Uses

🍳

Dal & Curries

Culinary

Pusa Arhar is primarily used to prepare dal (split pigeon peas), a staple protein-rich dish across India and South Asia. The peas are cooked into creamy curries, rice dishes, and pulse-based preparations that are nutritionally complete. [source]

🍳

Flour & Baked Goods

Culinary

Ground pigeon pea flour is used in traditional breads, pancakes, and snacks. The flour is also blended with wheat flour to enhance protein content and nutritional value in various baked products. [source]

💊

Traditional Medicine

Medicinal

Pigeon pea is used in Ayurvedic medicine to improve digestion, boost immunity, and support respiratory health. Seeds, leaves, and roots have been traditionally employed for their warming and nutritive properties. [source]

🏠

Nitrogen Fixation & Soil Improvement

Household

As a legume, Pusa Arhar improves soil fertility through symbiotic nitrogen fixation via Rhizobium bacteria, reducing dependence on synthetic nitrogen fertilizers. Plant residues can be incorporated as green manure. [source]

🦋

Livestock Feed & Fodder

Wildlife

Plant residues and fodder from Pusa Arhar are valuable nutritious feed for cattle, goats, and other livestock. The protein-rich crop supports sustainable mixed-farming systems. [source]

Harvest Tips

Harvest when pods are completely dry and brown, typically 150-170 days after planting. Pods should rattle when shaken, indicating seed maturity. Hand-harvest by picking individual pods or cut whole plants and dry further on ground for 7-10 days before threshing. Thresh by beating dried plants to release seeds from pods. Clean and dry seeds to 12% moisture content for storage.

Fun Facts

  • 🌱 Pusa Arhar was specifically developed at IARI (Indian Agricultural Research Institute) to address the need for early-maturing pigeon pea varieties, reducing crop duration from 180-240 days to just 150-170 days.
  • 🌱 Pigeon pea is one of the most ancient pulses, with evidence of cultivation dating back over 3,500 years in India, and Pusa Arhar represents modern breeding efforts to enhance traditional varieties.
  • 🌱 A single pigeon pea plant can remain productive for 3-5 years if not harvested completely, making it a semi-perennial legume; however, Pusa Arhar is typically managed as an annual crop for maximum yield and disease management.
