The Growth Stages of Chickpeas
The life cycle of chickpeas can be divided into several stages, each critical for the healthy development of the plant.
Germination
The journey of a chickpea plant begins with germination, which typically occurs within 7 to 10 days after sowing, depending on moisture and temperature conditions. During this stage, the seed absorbs water, and the seed coat cracks open, allowing the radicle (primary root) and cotyledon (seed leaf) to emerge.
Seedling Stage
Following germination, the chickpea enters the seedling stage, characterized by the development of the first set of true leaves. This stage is crucial, as the seedling establishes its root system and begins photosynthesis. Supportive conditions, including adequate light and protection from pests and diseases, are vital for the seedling’s survival and growth.
Vegetative Growth
As the seedling matures, it enters the vegetative growth phase, marked by the development of branches, leaves, and roots. Chickpea plants are either determinate or indeterminate, depending on their growth habit. Determinate varieties are bushy and compact, while indeterminate varieties are vining and require support.
Reproductive Stage
The reproductive stage is when the chickpea plant produces flowers and subsequently pods. This stage is critical for yield, as the number of flowers that successfully develop into pods directly affects the quantity of chickpeas produced. Flowers are self-pollinating but can also be cross-pollinated by insects.
Maturity and Harvest
Chickpeas are ready for harvest when the plants turn yellow and the pods are dry and brittle. The timing of harvest is crucial, as delayed harvesting can lead to pod shattering and loss of yield. Chickpeas can be harvested mechanically or by hand, depending on the scale of production and available resources.
