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.

Common Bean is susceptible to 3 known diseases. Early detection is critical — use the CuraPlant app to scan leaves and get an instant AI diagnosis.

1. 1

   Use certified disease-free seed — bean diseases are heavily seed-borne

2. 2

   Inoculate with Rhizobium phaseoli if first-time planting

3. 3

   Bush types: 50 × 10 cm. Climbing types: 75 × 30 cm with 2 m stakes

4. 4

   Avoid overhead irrigation — drip or furrow preferred to reduce foliar diseases

5. 5

   Harvest when pods are dry and rattling — do not leave in field during rain

6. 6

   Store dry beans with proper fumigation to prevent bruchid weevil damage

Strategic companion planting reduces pest pressure, improves pollination, and can significantly increase yields.
