Which of the following method is useful for increasing the rate of pollination and facilitating higher crop yield ?
(a) Apiculture
(b) Sericulture
(c) Dairying
(d) Fishery

Options

A. Apiculture
B. Sericulture
C. Dairying
D. Fishery

Answer

To solve the question regarding which method is useful for increasing the rate of pollination and facilitating higher crop yield, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which method can increase the rate of pollination and thereby enhance crop yield. Pollination is the transfer of pollen grains from the male part of a flower to the female part.

2. **Identify the Options**: The options provided are:
- (a) Apiculture
- (b) Sericulture
- (c) Dairying
- (d) Fishery

3. **Analyze Each Option**:
- **Apiculture**: This refers to beekeeping. Bees are known to be significant pollinators for many crops. They collect nectar from flowers, which not only helps in honey production but also aids in the pollination process, leading to increased crop yield.
- **Sericulture**: This involves the cultivation of silkworms to produce silk. It does not relate to pollination or crop yield.
- **Dairying**: This is the production of milk and dairy products. It does not involve pollination.
- **Fishery**: This pertains to the breeding and harvesting of fish. It is unrelated to pollination.

4. **Conclusion**: Given the analysis, the only method that directly relates to increasing the rate of pollination and facilitating higher crop yield is **Apiculture** (option a).

5. **Final Answer**: The correct answer is (a) Apiculture.
