Seedling
2-3 weeksSingle 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.
Vegetative Growth
6-8 weeksPlant 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.
Flowering
3-4 weeksSmall 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.
Pod Development & Fruiting
6-8 weeksFlowers 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.
Maturity & Harvest
2-3 weeks before harvestPods 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.

Uses
Dal & Curries
CulinaryPusa 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
CulinaryGround 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
MedicinalPigeon 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
HouseholdAs 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
WildlifePlant 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.
