Question

The crop that requires more irrigation is ___.
A) Wheat
B) Rice
C) Maize
D) Jowar

Answer 1

Hint: Irrigation is the technique of applying controlled amounts of water to land in order to aid agricultural production. In arid places and during seasons of below-average rainfall, irrigation aids in the growth of agricultural crops, the maintenance of landscapes, and the revegetation of damaged soils.

Complete answer:
Rice is one of the world's most important staple foods, and India is one of the world's top producers. Its manufacturing, however, necessitates a large amount of water. As the world's population grows, so does the need for food crops, which raises the amount of water needed to irrigate them. A pound of rice requires 3,000 to 5,000 gallons of water in traditional farming. Flooded soil is required for the crop's growth since it suppresses weed development and enhances the uptake of nutrients from the soil, resulting in a higher yield.

Let us look at the given options:
A) Wheat: This option is incorrect because this plant does not require a lot of water. It is a temperate climate crop. It requires a moderate amount of rainfall of 25-75 cms and an ideal temperature of 15°-20°C for cultivation.
B) Rice: This is the correct option. It is a staple food crop for the vast majority of Indians. After China, our country is the world's second-largest rice producer. It's a Kharif crop that demands high temperatures (over 25°C) and high humidity, as well as an annual rainfall of more than 100 cm. It flourishes with the help of irrigation in locations where rainfall is scarce.
C) Maize: This option is incorrect because it may be grown in temperatures ranging from 21°C to 27°C with 50-100cm of rainfall. Maize thrives in weather that alternates between rainy and sunny periods. It does not require more irrigation.
D) Jowar: This option is incorrect because it does not require more irrigation. It thrives in hot, arid areas with annual rainfall ranging from 45 to 100 cm.

Thus, the correct answer is Option B) Rice.

Note: Crop water demand is the amount of water required by plants for survival, growth, development, and the production of economic components. This requirement is met either naturally through rainfall or artificially through irrigation. Rice consumption varies from 6 to 10 mm per day, with total water consumption ranging from 1100 to 1250 mm depending on agro climatic conditions, variety duration, and soils.
