Explanation:

Ans. Hypogeal 

The type of germination in field pea is called : Hypogeal 

Germination is the beginning of growth of a seed. The seed must have the right level of warmth and moisture to begin to germinate. First, the seed leaves absorb moisture which allows the food reserves to become available to the new plant. It can then produce a root so that it can find its own water, followed by a shoot which develops from the plumule, which will allow it to absorb light. The plant needs both water and light to grow.

Sometimes, the seed leaves, or cotyledons, remain below the surface of the soil, as in germination of a Pea, below. This is called Hypogeal Germination.
