In order to ensure water availability and ultimately food security, it is now crucial to specify proper planning and management for irrigated agricultural land due to the unrestricted misuse of available water resources. Only after precise calculation of the water requirements of various crops and planned application in various fields is this feasible. Modelling is one of the main strategies used by scientists and researchers for achieving this goal.
The Food and Agricultural Organization's (FAO) Land and Water Development Division created the CROPWAT 8.0 model, which was utilized in this study to determine crop evapotranspiration and yield responses to water in the agro-ecological units (AEUs) in the Angul district of Orrisa. Estimating the water demand of important crops and scheduling irrigation to improve water usage efficiency are the main goals of this article.
According to the outcomes, rice crops demand the most water, followed by onions. The months of January and April are reported to have the highest water demands for rice crops. However, the months of January and December are when the onion crop needs the most water.
