Dry Beans — Planting

Metadata research draftEvidence limits

⚠️ Status: drafted from the literature survey. Values Unknown until source notes/full text. Use docs/methodology/units.md (cm, plants/m²).

Seed

• Home-growers grow the dry-bean kernel (“seed”) that is also the food product. Varieties: bush (dwarf) × climbing (pole). Choose sowing/consumption matching. Unknown seed-tray quality for garden.

Germination

• Cold/suboptimal seedbed slows germination (candidate 10.4141/p02-185). Germination temp threshold Unknown (warm-season; Around 15–20 °C optimum typical, source).
• Salinity reduces germination (candidate 10.15835/nbha4017493).

Direct sowing vs transplant

• Direct-sow beans (large seed: easy to place); transplant unusual. Unknown for Mexican home practice.

Depth

• Sowed 2–4 cm typically (larger seed than chia/amaranth). Precise Unknown.

spacing / rate

• Row × plant spacing, density (bush vs pole), seeding rate (kg/ha) — several studies (candidate 10.21275/v5i6.nov164504, 10.4141/p02-185). Values Unknown until full text.
• Intercropping with maize common (candidate 10.5897/ajar10.170) — small-scale compatible.

dates

• Sown after last frost, when soil warms; date windows by latitude/season. Mexico practice Unknown.
