Chickpeas vs edamame

If you’re deciding between growing chickpeas or edamame, the short answer is: edamame is easier, faster, and more reliable in most US gardens, while chickpeas are more drought-tolerant but need a long, warm, dry season to produce a worthwhile harvest. Choose edamame if you want a sure thing in a short season; choose chickpeas if you have hot, dry summers and patience for a longer crop. Here’s the full breakdown to help you decide.

Climate and Growing Season

Chickpeas (garbanzo beans) are a cool-season crop in Mediterranean climates, but they need a long, warm, dry period to mature. They thrive in USDA zones 7-11, but in zones 5-6, you’ll need to start early and hope for a dry fall. They are frost-sensitive, so plant after the last frost date, but they dislike extreme heat above 90°F during flowering. In the Pacific Northwest or Northeast, chickpeas often struggle with excess moisture and fungal diseases.

Edamame (soybeans) are warm-season annuals, perfect for zones 3-9. They need warm soil (at least 60°F) and a growing season of 75-100 days. They handle humidity well and are much more forgiving of rain. In short, edamame fits a wider range of US climates.

Planting and Spacing

Chickpeas:

• Plant seeds 1-2 inches deep, 6-8 inches apart, in rows 18-24 inches apart.
• In zone 7 and warmer, plant in early spring (February-March) for a summer harvest. In cooler zones, plant as soon as soil can be worked in spring.
• Inoculate with pea/bean inoculant (Rhizobium) to boost nitrogen fixation.

Edamame:

• Plant seeds 1-2 inches deep, 2-4 inches apart, in rows 24-30 inches apart.
• Wait until soil temperature is consistently above 60°F, usually late spring (May in most zones).
• Inoculate with soybean-specific inoculant, though edamame will still produce without it.

Varieties to Try

Chickpeas:

• ‘Sierra’ (short season, 90-100 days), ‘Dwarf Green’ (compact, good for containers), ‘Black Kabuli’ (dark, nutty flavor).
• For zones 5-6, choose ‘Sierra’ for the earliest maturity.

Edamame:

• ‘Envy’ (early, 75 days), ‘Midori Giant’ (large beans, 85 days), ‘Chiba Green’ (sweet, 80 days).
• All are reliable in most US gardens.

Yield and Harvest

Chickpeas:

• Expect 1-2 pounds of dried chickpeas per 10-foot row. A 100-foot row yields about 10-20 pounds.
• Harvest when the lower leaves turn brown and pods rattle. Pull the whole plant, dry for 1-2 weeks, then thresh.
• Yield is highly dependent on dry weather; wet conditions can cause mold.

Edamame:

• Expect 2-4 pounds of pods per 10-foot row. A 100-foot row yields 20-40 pounds.
• Harvest when pods are plump and still bright green, usually 75-100 days after planting. Pick before they yellow.
• You can harvest over a 2-3 week period as pods mature.

Soil, Water, and Fertilizer

Both legumes prefer well-drained soil with pH 6.0-7.0. Add compost before planting. Avoid high-nitrogen fertilizer; legumes fix their own nitrogen. Water chickpeas sparingly, especially after flowering, to prevent disease. Edamame needs consistent moisture, especially during pod formation; water 1-1.5 inches per week.

Pests and Problems

Chickpeas:

• Watch for aphids and cutworms. Use row covers early. Fungal diseases like Ascochyta blight are common in humid areas; choose resistant varieties and ensure good air circulation.

Edamame:

• Japanese beetles and bean leaf beetles can be a problem. Handpick or use neem oil. Deer love edamame, so fence if necessary.

Cost and Time Investment

Seeds: Chickpea seeds cost about $5-$8 per ounce (roughly 100 seeds), enough for a 50-foot row. Edamame seeds are similar, $4-$6 per ounce (about 150 seeds). Both are inexpensive compared to buying at the store.

Time: Edamame requires less hands-on time; chickpeas need more weeding and monitoring for disease. Harvesting chickpeas involves drying and threshing, which takes extra days.

Cooking and Storage

Chickpeas:

• Dried chickpeas store for years in airtight containers. Soak overnight and cook for 1-2 hours. Use in hummus, curries, or roast for snacks.

Edamame:

• Blanch and freeze pods for up to 6 months. Shell and use in salads, stir-fries, or as a snack with salt.

FAQ

Can I grow chickpeas in a short-season climate? Yes, but it’s risky. Choose ‘Sierra’ and start indoors 4 weeks before last frost. Even then, a wet summer can ruin the crop. Edamame is a safer bet.

Do I need special inoculants? Inoculants help but aren’t mandatory. For chickpeas, use a pea/bean mix; for edamame, use soybean inoculant. You can buy them online or at garden centers for $8-$12.

How much space do I need? For a family of four, plant a 50-foot row of each. That yields about 5-10 pounds of chickpeas and 10-20 pounds of edamame pods, enough for several meals.

Can I grow them in containers? Edamame works in 5-gallon pots (one plant per pot). Chickpeas are less suited; their taproot is deep, so use at least a 10-gallon container and keep them dry.

The Bottom Line

For most gardeners, edamame is the winner: it’s easier, more productive, and more forgiving. Chickpeas are worth trying if you have a hot, dry climate and want a storage crop. Start with edamame for a guaranteed harvest, then experiment with a short-season chickpea variety if you’re curious. Either way, you’ll enjoy fresh, homegrown legumes that beat anything from the store.
