Question

Match List-I with List-II

List-I (Crop)	List-II (Seasonal crop evapotranspiration (mm))
(A) Beans	(IV) 250-500
(B) Cotton	(V) 550-950
(C) Maize	(I) 400-750
(D) Sorghum	(III) 300-650
(E) Soybeans	(II) 450-825

• A. (A)-(V), (B)-(I), (C)-(II), (D)-(IV), (E)-(III)
• B. (A)-(V), (B)-(I), (C)-(IV), (D)-(III), (E)-(II)
• C. (A)-(IV), (B)-(V), (C)-(I), (D)-(III), (E)-(II)
• D. (A)-(III), (B)-(V), (C)-(II), (D)-(IV), (E)-(I)

Hint:

To remember seasonal water requirements, arrange crops from lowest to highest:
Beans (250-500 mm) < Sorghum (300-650 mm) < Maize (400-750 mm) < Soybean (450-825 mm) < Cotton (550-950 mm).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Seasonal crop evapotranspiration (\(\text{ET}_c\)) represents the total amount of water lost through transpiration from the crop canopy and evaporation from the soil surface over the entire growing season.
It varies widely depending on the crop's duration, leaf area index, rooting depth, and climatic conditions.

Step 2: Detailed Explanation:
Let us match each crop with its typical seasonal water requirement range based on FAO guidelines:
- (A) Beans:
Beans are relatively short-duration crops with a shallow root system, resulting in a low seasonal water requirement, typically ranging from 250 to 500 mm.
Thus, (A) matches with (IV).
- (B) Cotton:
Cotton is a long-duration cash crop grown during the hot season, requiring a high amount of water, typically ranging from 550 to 950 mm (or even higher in extremely arid climates).
Thus, (B) matches with (V).
- (C) Maize:
Maize is a C4 crop with moderate to high water requirements, typically ranging from 400 to 750 mm over its growth cycle.
Thus, (C) matches with (I).
- (D) Sorghum:
Sorghum is a highly drought-tolerant C4 crop with a medium water requirement, typically ranging from 300 to 650 mm.
Thus, (D) matches with (III).
- (E) Soybeans:
Soybean is a legume with a medium-high seasonal water requirement, typically ranging from 450 to 825 mm.
Thus, (E) matches with (II).
Combining these matches, we get: (A)-(IV), (B)-(V), (C)-(I), (D)-(III), (E)-(II).

Step 3: Final Answer:
The correct matching sequence corresponds to Option C.
