Dapog method of crop raising is associated with

Answer: Option C

Explanation:
The correct answer is Option C: nursery raising.
Let's break down why:

* Dapog Method: This is a special way of growing rice seedlings before they are transplanted to the main field.
* Nursery Raising: This refers to the process of nurturing young plants in a controlled environment (the nursery) before they are planted in the field.

The Dapog method is a form of nursery raising where rice seedlings are grown very densely on a prepared surface (often concrete or plastic sheets) without soil. This makes it easier to transplant them.

* Interculture operation: This refers to practices done between rows of crops after they've been planted (e.g., weeding).
* Seed-bed preparation: This is about preparing the soil where seeds are directly sown, not a specific method for raising seedlings before transplanting.
* Inter-cultivation: Same as interculture operation

Therefore, the Dapog method is directly related to nursery raising.
