Which of the following method is likely to be used where the water supply is limited and the market value of the crop is high?

Correct option is B

Explanation of the Correct Option (b): Drip irrigation
· Drip irrigation supplies water directly to the root zone of the crop.
· Water is applied drop by drop, minimizing losses due to:
· Evaporation
· Runoff
· Deep percolation
· It ensures maximum water use efficiency (up to 90–95%).
· Initial cost is high, hence it is economically suitable for:
· High-value crops (vegetables, fruits, orchards, floriculture)
· Especially recommended in water-scarce regions.
· Therefore, drip irrigation is the most suitable method when water supply is limited and crop value is high.
Explanation of Other Options
Option (a): Sprinkler irrigation
· Uses more water than drip irrigation.
· Losses occur due to:
· Wind drift
· Evaporation
· Suitable for medium water availability, not severe scarcity.
Option (c): Furrow irrigation
· A traditional surface irrigation method.
· Causes:
· Uneven water distribution
· High water loss due to runoff and percolation
· Not suitable where water is limited.
Option (d): Surface irrigation
· Includes flooding and basin methods.
· Least efficient in terms of water use.
· Requires abundant water supply.
Key Points:
· Drip irrigation → Best for limited water + high-value crops
· Highest water use efficiency among irrigation methods
· Common crops: grapes, banana, vegetables, flowers
· Promotes uniform growth and higher yield
