There are two types or market classes, divided according to seed size. Desi are shorter stature with smaller seeds, darker, thicker seed coats, wrinkled and irregular in shape. Kabuli are later maturing than Desi. The cotyledons remain below ground during germination and have the ability to re-grow if the top growth is damaged by frost. Optimal rainfall is 8-12 inches during the growing season.
Chickpea is well adapted to the drier parts of the brown and dark brown soil zones of the prairies.
Weeds are well adapted to local environment. Most germinate in early spring. Wild mustard and wild oats are vigourous competitors. Green foxtail, lamb's quarters, and wild buckwheat are less vigourous. Weeds compete with crop for nitrogen.
