Answer 2

Answer:

Option c - cultivating more than one crop on the same field each year.  

Explanation:

• Multiple cropping is the practice of growing two or more crops in a place.
• When multiple crops are grown this is called intercropping.
• It doubles the crop productivity and income for the farmers.
• The selection of two or more crops needs lots of research and practice. The success rate depends on the mutual benefit of the selected crops.  
• Cultivating on a large scale can help in the reduction of the food crisis in our country.
• Multiple cropping reduces the risk of weed growth, disease infestation and pest problems.
• The overall cost spent on fertilizers, input decreases, and labour reduces because of growing two or more crops on the same.
• Only 5% of global rainfed cropland is under multiple cropping.
• About 40% of global irrigated cropland is cultivated under multiple cropping.

Hence, cultivating more than one crop on the same field is called multiple cropping.
