Question

Read the following statements and identify the false one.

• A. Water requirement of rice is higher as compared to that of wheat and maize.
• B. The crops grown in sandy soils needs more irrigation.
• C. The frequency of irrigation is higher in the summer season.
• D. Clayey soil requires frequent irrigation as it cannot hold water molecule for a longer time.

Answer 1

The correct option is D Clayey soil requires frequent irrigation as it cannot hold water molecule for a longer time.

Water requirement of rice is higher as compared to that of wheat and maize. In case of crops like wheat and maize, excess water supply to the fields may result in a condition known as waterlogging.
The crops grown in a sandy soil need irrigation more frequently because it has less water holding capacity; whereas the frequency of irrigation for the crops grown in a clayey soil is less.
In summer, the frequency of watering is increased due to higher loss of water in the form of water vapors from the soil and the leaves.
