The percentage of CCA (culturable commanded area) proposed to be irrigated in a given season is called intensity of irrigation.
The annual irrigation intensity is usually found to be in the range of 40 to 60%. But needs to be raised in the range of 100 to 180% by cultivating larger parts of CCA with more than one crop in a year.

The intensity of irrigation can vary depending on various factors, including the crop being grown, the soil type, and the climate conditions.
Intensity of irrigation refers to the amount of water applied to the crop and how frequently it is applied. It is usually measured in terms of the depth of water applied (in millimeters or inches) over a given area (hectares or acres) and the time interval between irrigation events.
In general, the intensity of irrigation can be classified into three categories:
1. Low intensity: In low intensity irrigation, water is applied infrequently and in small amounts. This method is commonly used in arid regions where water availability is limited. It aims to maximize water use efficiency by minimizing water losses through evaporation or runoff.
2. Moderate intensity: Moderate intensity irrigation involves applying water at regular intervals in moderate amounts. This method is used in regions with moderate rainfall or where water availability is relatively higher. It aims to meet the crop's water requirements while minimizing water losses.
3. High intensity: High intensity irrigation involves applying water frequently and in large amounts. This method is used in regions with high rainfall or where water availability is abundant. It aims to provide excess water to the crop to ensure optimal growth and productivity.
The intensity of irrigation is typically determined through various factors, including the crop's water requirements, soil moisture levels, weather conditions, and irrigation system efficiency. It is important to strike a balance between providing enough water to meet the crop's needs and avoiding over-irrigation, which can lead to waterlogging, nutrient leaching, and other negative impacts on crop growth and the environment.
