    Define the term ‘intensity of cropping’. Explain two reasons with suitable examples for the uneven distribution of intensity of cropping in India.                             3x1= 3

    Marks:3
    Answer:

    The amount of crops produced in an agricultural field during an agricultural year is known as intensity of cropping. The intensity of cropping at the national level is 135% in an agricultural year. The uneven distribution of the crops in the agricultural fields can be shown by the following examples:

    1. The intensity of cropping is higher in the northern fertile land where alluvial soils are found. These states are Uttar Pradesh, Bihar and West Bengal. On the other hand in Rajasthan and Gujarat, because of arid soil which is not fertile enough, the crop intensity is lesser.
    2. Irrigational facilities is another factor that causes uneven distribution of crop intensity in India. Like in U.P, Punjab and Haryana, irrigational facilities causes high crop intensity and in Gujarat and Rajasthan the intensity is low.
