1.Pea — Overview
Pisum sativum, commonly known as the garden pea, is an annual herbaceous plant. It grows as a climbing or bush-like form. It belongs to the expansive legume family, Fabaceae. People have cultivated this ancient crop for over 8,500 years. Its centers of origin trace to Ethiopia, the Mediterranean, and Central Asia.
Depending on the cultivar, the plant typically grows from 0.3 to 2.7 meters (1 to 9 feet) tall. It has hollow stems. It either uses vining tendrils for support or keeps a more compact, self-supporting habit in dwarf varieties.
Its distinctive leaves are alternate and pinnately compound. They often carry two large leaflike stipules, one to several pairs of oval leaflets, and terminal tendrils. Some modern cultivars show an 'afila' leaf type, in which leaflets become additional tendrils.
The flowers are zygomorphic and papilionaceous. They typically appear in racemes from leaf axils, in white, purple, or pink hues. These bisexual flowers are mainly self-pollinating.
They develop into characteristic closed pods, usually 2.5 to 10 cm (1 to 4 inches) long. The pods contain ovate to spheroidal seeds, the edible peas. Ripe seeds vary in color from green, yellow, and beige to dark violet.
The plant establishes a taproot system with numerous lateral branches. It forms symbiotic relationships with nitrogen-fixing bacteria (Rhizobium leguminosarum) in root nodules. These relationships significantly enrich soil fertility.
Pisum sativum is widely distributed and cultivated in temperate regions globally. It thrives in cool seasons and well-drained, fertile soils with a pH range of 5.5 to 7.0.

5.Pea — Water Requirements
- Cool-Season Annual — Pisum sativum thrives in cooler temperatures, typically planted in early spring or fall, and is sensitive to high heat during flowering.
- Soil Requirements — Prefers fertile, light-textured, well-drained soils with an optimal pH range of 5.5 to 7.0, and is sensitive to salinity and extreme acidity.
- Planting — Seeds are typically sown 1.5 to 3 inches deep in rows spaced 6 to 12 inches apart, emerging in 10-14 days.
- Inoculation — In fields where peas haven't been grown, seeds should be inoculated with Rhizobium leguminosarum to ensure effective nitrogen fixation.
- Water & Light — Requires 16-39 inches of annual precipitation and performs best in full sun exposure with moderate water.
- Nutrient Management — Benefits from moderate fertility; soil testing is recommended to guide application of nitrogen, phosphorus, and potassium, avoiding excess nitrogen which can hinder pod development.
- Weed Control — Peas are poor competitors against weeds, necessitating strategies like rapid emergence, adequate crop density, pre- and post-plant tillage, and appropriate herbicides.
- Harvesting — Garden peas are harvested when seeds are immature and tender for fresh consumption, while field peas are allowed to mature and dry for storage and processing.
