Soybean Seeding Rate, Row Spacing and Planting Depth

Farmers usually aim for 350,000–450,000 seeds per hectare (140,000–180,000 per acre), roughly 60–90 kg/ha depending on seed size, planted 2.5–4 cm (1–1.5 in) deep. In gardens, sow seeds 5–10 cm apart in rows 40–45 cm apart.

Row Spacing

• Narrow rows (19–38 cm / 7.5–15 in): faster canopy closure, fewer weeds, often higher yield.
• Wide rows (76 cm / 30 in): easier cultivation and equipment sharing with corn.

Depth

Too shallow and seeds dry out; deeper than 5 cm and seedlings may fail to emerge, especially in crusted soil.

Containers

Use pots at least 30 cm deep; 3–4 plants per 30–40 cm pot.
