Field Pea

Pisum sativum subsp. arvense

vegetable

Field peas are a cool-season legume crop grown primarily for dried seeds used in soups, animal feed, and protein production. These hardy plants grow 2-3 feet tall with compound leaves and white, pink, or purple flowers followed by seed pods. They enrich soil with nitrogen through their symbiotic relationship with rhizobia bacteria.

Growth Stages

1

Germination & Seedling

10-14 days

Seeds sprout within 7-10 days in cool soil (45-60°F). Seedlings emerge with two cotyledons and begin developing true leaves.

Ensure good soil contact and adequate moisture. Thin seedlings if planted too densely. No fertilizer needed if inoculant was used.

2

Vegetative Growth

30-40 days

Plant develops compound leaves and climbing or bushy stem structure (depending on variety). Height increases to 1-2 feet. Robust root system with nitrogen-fixing nodules establishes.

Monitor for early pests (aphids, weevils). Provide support stakes or trellis if needed for vining types. Minimal fertilizer; avoid excess nitrogen.

3

Flowering

20-30 days

Small white, pink, or purple flowers appear in leaf axils. Flowering progresses from lower to upper plant portions.

Ensure consistent moisture during flowering to support pod set. Watch for flower-damaging pests and diseases.

4

Pod Development & Maturation

30-50 days

Flowers transition to green, then mature seed pods. Pods gradually fill with developing peas and turn tan or brown as they dry.

Continue regular watering until pods fill. Support vining varieties to prevent pod rot. Reduce watering as pods mature for field pea production.

5

Harvest-Ready

Harvest window 1-2 weeks

Pods are fully mature, tan or brown, papery, and rattle when shaken. Plants begin to dry down naturally.

Harvest when moisture content drops to 12-13% for storage. Pull or cut plants at soil level. Thresh pods to extract peas.

Common Pests

  • Spray with neem oil or insecticidal soap; encourage natural predators like ladybugs; resistant varieties available.

  • Use row covers until flowering; early harvesting; resistant varieties; insecticide application if severe infestations develop.

  • Ensure good air circulation; avoid overhead watering; apply sulfur dust or fungicide if needed; choose resistant varieties.

  • Use resistant varieties; practice crop rotation (3+ years); avoid waterlogging; remove infected plants promptly.

  • Plant resistant varieties; avoid overhead irrigation; remove infected leaves; crop rotation essential.

Harvest Tips

For field pea production (dried peas), harvest when pods are mature and brown, approximately 90-120 days from planting. Pods should be dry and brittle; seeds rattle inside. Cut or pull entire plants and hang to dry further in a sheltered location. Thresh pods by hand, hitting them against a surface, or use a mechanical thresher. Store dried peas in airtight containers in cool, dry conditions. Handle carefully to avoid cracking seeds.

Fun Facts

  • 🌱 Field peas have been cultivated for over 10,000 years, making them one of the oldest domesticated crops alongside wheat and barley.
  • 🌱 A single field pea plant can fix 50-150 pounds of nitrogen per acre through its relationship with Rhizobium bacteria, sometimes eliminating the need for synthetic nitrogen fertilizers.
  • 🌱 Canada is the world's largest producer and exporter of field peas, supplying peas to over 150 countries; pulse crops like field peas are increasingly popular as sustainable, climate-friendly protein alternatives.
