Which of the following has the largest seasonal crop water needs?

The correct answer is Sugar Cane.

Key Points

• Sugar Cane is a tropical crop that requires a large amount of water for its growth.
• The crop has a long growing season, often ranging from 9 to 24 months.
• Because of its long duration, it requires a consistent and substantial water supply.
• Typically, sugar cane requires around 1500-2500 mm of water during its growth cycle.
• This high water requirement is due to the plant's need to produce a significant amount of biomass and sucrose.
• Regions cultivating sugar cane often rely on irrigation systems to meet these water needs.

 Additional Information

•  Banana
  • Banana plants also require a substantial amount of water but less than sugar cane.
  • They typically need about 1200-2200 mm of water.
  • Bananas thrive in tropical climates with high rainfall.
• Potato​
  • Potato plants generally require 500-700 mm of water.
  • They have a shorter growing season, reducing their overall water needs.
  • Potatoes are often grown in temperate regions with adequate rainfall.
• Tomato
  • Tomato plants need about 400-800 mm of water.
  • They are more drought-tolerant than sugar cane and bananas.
  • Tomatoes can be grown in a variety of climates, from temperate to tropical.
