Question

Assertion (A): The Japanese method of rice cultivation yields three times higher than the conventional transplantation method.

Reason (R): The Japanese method uses High Yielding Variety (HYV) seeds and advanced techniques for better productivity.

Options

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true but (R) is not the correct explanation of (A).

• (A) is true but (R) is false.

• (A) is false but (R) is true.

Answer 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

The Japanese method of rice cultivation incorporates high-yielding variety (HYV) seeds, raised nursery seedbeds, and structured row transplantation alongside optimal dosing of chemical fertilizers. These advanced, systematic techniques ensure stronger root development, vastly minimize initial crop infections, and facilitate easier weeding compared to traditional broadcasting or broadcasting-transplantation methods. As a direct result of utilizing these scientifically superior inputs and field practices, the grain yield per hectare multiplies up to three times higher than conventional methods.
