Which of the following group of basic amenities should be provided in rural areas for improved agricultural productivity?

For improved agricultural productivity in rural areas, a specific set of basic amenities plays a crucial role. Let's consider each in detail:

• Water: It is essential for irrigation, which is fundamental to agriculture. Access to a reliable water supply helps ensure crops can be grown consistently, increasing agricultural output.
• Electricity: It facilitates the use of modern farming equipment and machinery, improves storage facilities for perishables, and enhances irrigation systems. This can drastically improve productivity and reduce labor costs.
• Health Care Centres: Ensuring farmers and agricultural workers remain healthy is vital for consistent productivity. Healthy workers are more efficient and can maintain the demanding physical labor often required in agriculture.

Hence, the combination of water, electricity, and health care centres is the most effective group of basic amenities to significantly improve agricultural productivity in rural areas. These provide the necessary infrastructure to support and sustain agricultural activities, thereby enhancing productivity and the overall quality of life in rural areas.
