Identify the crop on the basis of the following characteristics: 1. It is a kharif crop. 2. Aus, Aman and Boro are its three different growing periods in an agricultural year. 3. About one-fourth of the total cropped area of India is under its cultivation. Select the correct answer using the code given below :
- A.Wheat
- B.Rice
- C.Pulses
- D.Cotton
Correct answer
Explanation
The correct answer is B, Rice. Rice is mainly a kharif crop, and in West Bengal and the neighbouring states farmers grow three rice crops in a year: aus in the pre-monsoon and early monsoon season, aman in the main monsoon season with a winter harvest, and boro in winter and spring. Rice occupies about a quarter of India's total cropped area, more than any other single crop. It needs high temperature, high humidity and rainfall above 100 cm, or irrigation where the rain is less, which is why Punjab and Haryana grow it with canals and tube wells. Option A is wrong because wheat is a rabi crop sown in winter and has no aus, aman or boro seasons. Option C is wrong because pulses are grown in both seasons and cover a much smaller share of the cropped area. Option D is wrong because cotton is a kharif crop of the black soil regions, covers far less area and has no such three seasons. Exam tip: aus, aman and boro are the three rice seasons of Bengal, and aman is the main one.
