State four main features of intensive farming.

 In the context of the Class 10 chapter "Lifelines of National Economy," here are four main features of intensive farming:

1. High Input Use: Intensive farming relies on the extensive use of inputs such as fertilizers, pesticides, and high-yielding variety (HYV) seeds. This approach aims to maximize crop production from a given piece of land.

2. Small Land Holdings: This type of farming is typically practiced on small plots of land. Farmers often cultivate multiple crops on the same land to increase productivity and ensure better returns.

3. Labor-Intensive: Intensive farming is labor-intensive, requiring a significant amount of human effort for activities like planting, harvesting, and maintaining crops. This feature often leads to higher employment opportunities in rural areas.

4. Focus on Cash Crops: Farmers engaged in intensive farming often prioritize cash crops such as vegetables, fruits, and flowers over traditional food crops. This focus helps to maximize profits and meet market demands.

These features contribute to higher agricultural yields, supporting food security and economic development.
