Question

$\left(a\right)$ What is irrigation $?$ Why is irrigation necessary $?$

Answer 1

$\bullet$ Irrigation is the process of supplying water to crop plants in the field.

Irrigation is necessary because:

$\bullet$ Irrigation before ploughing the fields softens the soil, making it easier to plough the field.

$\bullet$ Irrigation is required to supply moisture for seed germination. This is because seeds do not grow in dry soil.

$\bullet$ Irrigation is necessary to maintain the moisture of soil for healthy crop growth so as to get good yield.

$\bullet$ Irrigation is necessary for the absorption of nutrient elements by the plants from the soil.

$\bullet$ Water supplied to the crops during irrigation protects the crop plants from hot air currents as well as frost.
