Cluster bean, commonly known as guar, is a drought-tolerant legume grown for its edible pods, leaves, and industrial gum from its seeds. It plays an important role in food security and income generation, especially in dry regions. In Kenya, cluster bean grows well in arid and semi-arid areas such as Kitui, Makueni, Kajiado, Tana River, and parts of Eastern Kenya. The crop produces green pods that are harvested for vegetables, and mature seeds are used in processing industries.

Varieties
Common guar types include local landraces and improved varieties such as Pusa Navbahar and Pusa Sadabahar. These varieties differ in pod size, maturity period, yield potential, and drought tolerance. Some produce tender pods for vegetable use, while others focus on high seed yield for guar gum production.

Growing Conditions
Cluster bean grows best in warm, dry climates with temperatures of 25–35 °C and rainfall of 300–800 mm. It thrives in well-drained sandy or loamy soils with a pH of 7.0–8.0. The crop performs well under full sunlight and tolerates drought conditions. Waterlogging reduces growth and lowers seed yield.

Growth Cycle
Grows from seeds and develops into upright bushy plants with trifoliate leaves. It produces clusters of slender green pods along the stems. Farmers harvest young pods for vegetables and allow some plants to mature fully for seed production.

Nutritional Value
The pods contain fibre, protein, vitamins A and C, and minerals such as calcium and iron. These nutrients support digestion, blood health, and overall nutrition.

Uses & Market Potential
Cluster bean is used as a vegetable, livestock feed, and industrial raw material. Its seeds produce guar gum, widely used in food processing, cosmetics, and pharmaceuticals. Growing demand in arid regions creates strong opportunities for commercial production and value addition.
