Hii
(1) About 80 per cent of the total annual rainfall of India occurs in four months, i.e. from mid-June to mid-October. So it is essential to provide irrigation for production of crops etc, during the rest of the eight months.
(2) The monsoons are uncertain. So irrigation is necessary to protect crops from drought as a result of uncertain rainfall.
(3) It does not rain equally in all parts of the country. So irrigation is necessary for agriculture in less rainfall areas.
Hope thse would helps u ✌
