The correct Answer is:
To solve the question regarding hydroponics, we will analyze each statement one by one to determine which ones are correct. ### Step-by-Step Solution: 1. **Understanding Hydroponics**: Hydroponics is a method of growing plants without soil, using a nutrient-rich water solution. This technique allows for precise control over nutrient delivery and can be beneficial in areas with poor soil conditions. 2. **Evaluating Statement I**: - **Statement**: Hydroponics technique is useful in areas having infertile and dry soils. - **Analysis**: This statement is correct. Hydroponics is particularly advantageous in regions where the soil is not suitable for traditional agriculture, as it allows for plant growth in a controlled environment without the need for fertile soil. 3. **Evaluating Statement II**: - **Statement**: Hydroponics can regulate pH optimum for a particular crop. - **Analysis**: This statement is also correct. Hydroponic systems allow growers to monitor and adjust the pH levels of the nutrient solution to optimize conditions for specific crops, which is crucial for nutrient uptake. 4. **Evaluating Statement III**: - **Statement**: It increases the labour cost. - **Analysis**: This statement is incorrect. Hydroponics typically reduces labor costs because it can automate many processes and requires less manual labor compared to traditional farming methods. 5. **Evaluating Statement IV**: - **Statement**: It increases the problem of weeding. - **Analysis**: This statement is also incorrect. Since hydroponics does not involve soil, the issue of weeds is significantly minimized, making it easier to manage plant growth. ### Conclusion: Based on the evaluation: - **Correct Statements**: I and II - **Incorrect Statements**: III and IV Thus, the correct answer is that statements I and II are true regarding hydroponics.
