Development of rotational water allocation plan for a command area of Som-Kagdar irrigation project

In the present study, diagnostic analysis of the irrigation system was done and a rotational water allocation plan on the basis of ET requirement of crops was developed for a command area. The crop water requirements for the major Rabi crops viz. wheat, gram and barley were computed by Penman-Monteith method using computer program ‘CROPWAT’ and these were used in the development of rotational water allocation plan. This system leads to increased credibility and reliability, enhanced equity in water distribution, proper utilization of water resources and increased water use efficiency.
