Cajanus cajan
vegetableRed pea, commonly known as pigeon pea or arhar, is a drought-tolerant legume native to India that produces nutritious seeds in pods. The plant is a perennial shrub often grown as an annual, reaching 3-6 feet tall with yellow flowers followed by elongated pods containing 2-4 seeds. Red peas are a staple protein source in tropical and subtropical regions worldwide, especially in Caribbean, African, and South Asian cuisines.

Germination & Seedling
2-3 weeksSeeds sprout within 7-10 days. Seedlings emerge with two cotyledons and develop their first true leaves.
Keep soil consistently moist but not waterlogged. Provide full sun. Thin seedlings to proper spacing if direct seeding.
Vegetative Growth
4-6 weeksPlant develops compound leaves, establishes a strong root system, and grows taller. Stems become woody and the plant takes on a bushy shrub-like form.
Maintain moderate moisture. Apply mulch around base. No heavy fertilization needed; excess nitrogen reduces flowering. Support tall varieties with stakes if needed.
Flowering
3-4 weeksYellow or yellow-orange flowers appear in clusters at branch tips. Flowering typically occurs 60-90 days after planting.
Maintain consistent watering without overwatering. Avoid high-nitrogen fertilizers which promote foliage over blooms. Flowers are self-pollinating.
Pod Development & Maturation
4-6 weeksSmall pods form after pollination and gradually enlarge. Pods contain 2-4 peas that develop and harden. Pods may show color variation from green to reddish-brown.
Reduce watering as pods mature. Monitor for pests. Do not over-fertilize. Pods are ready when they turn brown and dry on the plant.
Harvest Ready
At harvest readinessPods have fully dried on the plant and turned brown or reddish. Seeds inside are hard and fully mature.
Monitor weather; harvest before heavy rains if possible. Allow pods to dry completely for storage. Properly dried seeds store well for months.

Harvest Tips
Harvest when pods have fully dried on the plant and turned brown (120-150 days after planting). Pods should rattle when shaken, indicating dry seeds inside. In humid climates, cut entire plant and hang to dry indoors. Shell pods by hand or thresh to separate seeds. Store dried seeds in airtight containers in a cool, dry place.
Fun Facts
- 🌱 Red pea plants are perennial shrubs that can be maintained for 3-5 years of continuous production in tropical climates, though they're often grown as annuals.
- 🌱 The name 'pigeon pea' likely derives from its use as a feed for pigeons, and the plant has been cultivated in India for over 3,500 years.
- 🌱 Red peas are extremely drought-tolerant and can thrive in marginal soils where many crops fail, making them valuable for food security in arid and semi-arid regions.
