About Common Bean
The common bean is the most important food legume for direct human consumption, providing affordable protein for over 500 million people, particularly in Latin America and sub-Saharan Africa. Beans are the primary protein source for low-income families where animal protein is scarce or unaffordable. Eastern and southern Africa consume more beans per capita than any other region. Both bush (determinate) and climbing (indeterminate) types are grown. Dry beans contain 22% protein, iron, zinc, folate, and fiber, making them a nutritional powerhouse. Annual global production exceeds 27 million tonnes.
Growing Conditions
Full sun — 6+ hours daily
300-500 mm per crop. Critical during flowering and pod fill. Drought at flowering causes severe flower drop.
Well-drained loam. pH 5.8-7.0. Beans are sensitive to both acidic and alkaline soils.
Optimal 18-24°C. Sensitive to frost and heat above 30°C (causes flower drop).
Moderate. High humidity promotes angular leaf spot, anthracnose, and root rots.
Warm season — 60-90 days for bush types, 90-120 days for climbers.
Step-by-Step Growing Tips
Use certified disease-free seed — bean diseases are heavily seed-borne
Inoculate with Rhizobium phaseoli if first-time planting
Bush types: 50 × 10 cm. Climbing types: 75 × 30 cm with 2 m stakes
Avoid overhead irrigation — drip or furrow preferred to reduce foliar diseases
Harvest when pods are dry and rattling — do not leave in field during rain
Store dry beans with proper fumigation to prevent bruchid weevil damage
