We irrigate our crops so that growth of our crop is not affected due to lack of water. Water is an essential requirement of plants which supports its growth and if plants did not receive water at the stages where they require water, crops will be destroyed. Water is required in photosynthesis process (process of making food by the plants in the presence of sunlight, carbondioxide and water) also. Since, water is an integral part of the growth of the plants we need to irrigate our crops otherwise they will die and we will suffer from loss of crops.
In order to get a high yield we must ensure that crops remain healthy and it is only possible when we irrigate our crops at the stages where they require water.
Therefore, irrigation is quite important and we must irrigate our crops at right stages.
