Water is a basic requirement for the crops to grow. Plants do not develop properly in dry conditions. The essential nutrients are transported to the plant part with the help of water flowing in them. This would not be possible without water. Water stands as a barrier in order to protect the crop from hot air current and frost. Water is essential for the germination of seeds.
For a crop to remain healthy, regular watering of the crop is necessary. Water requirements are different for different crops. For instance, water requirements are less for wheat as compared to the water requirements of paddy crops that need constant supply of water.
Rainfall is a major source of water for crops. Owing to the uncertainty of the rainfall, alternative methods have been devised to provide the adequate supply of water to the program at regular intervals.
