Question

Farmers in a region experiencing moderate rainfall, cool winters, and assured irrigation plan to move from mixed cropping to the cultivation of a single cereal crop. Should they opt for rice or wheat? Support your answer with appropriate reasons based on crop requirements.

Hint:

Match cool winters, 50-75 cm rain and ripening sunshine with the crop that needs them.

Answer 1

Step 1: Understanding the Question:
The region has moderate rainfall, cool winters and assured irrigation. We must compare these conditions with what rice and wheat need, and then choose one crop.

Step 2: Requirements of rice:
Rice is a kharif crop. It needs high temperature (above 25 degrees Celsius), high humidity and heavy rainfall (above 100 cm). Where rain is less, it needs irrigation. Cool winters and moderate rain do not suit it.

Step 3: Requirements of wheat:
Wheat is a rabi crop. It needs a cool growing season and bright sunshine at the time of ripening. It needs about 50 to 75 cm of rainfall, evenly spread over the growing period.

Step 4: Reason 1: Temperature:
Cool winters match wheat, which grows well in cool temperatures during the growing season.

Step 5: Reason 2: Rainfall:
Moderate rainfall matches the wheat requirement of 50-75 cm. Rice needs much more.

Step 6: Reason 3: Sunshine:
Wheat needs bright sunshine when it ripens, which is common in winter months.

Step 7: Reason 4: Irrigation:
Assured irrigation helps wheat where rain is limited. It is also true that in the north and north-western plains, wheat is grown with irrigation.

Step 8: Reason 5: Region:
Wheat is traditionally grown in the north and north-western regions, where such conditions are found.

Step 9: Decision:
All conditions favour wheat. So the farmers should choose wheat.

Final Answer:
The farmers should opt for wheat because its needs match the climate and water supply of the region. \[ \boxed{\text{Wheat}} \]
