Root system of chickpea:

Chickpea plants have a strong taproot system with 3 or 4 rows of lateral roots. The parenchymatous tissues of the root are rich in starch.  All the peripheral tissues disappear at plant maturity, and are substituted by a layer of cork. The roots grow 1.5-2.0 m deep. Chickpea roots bear Rhizobium nodules. They are of the carotenoid type, branched with laterally flattened ramifications, sometimes forming a fanlike lobe.
