Abstract:
Water is considered as a major input for agriculture production, earlier crop
water needs were met by rain water alone. But increasing population demands
enhanced food and agricultural production. This has made irrigation inevitable. The
primary objective of irrigation is to provide plants with sufficient water to obtain
optimum yields and a high quality harvested product. The scientific management of
irrigation system is necessary to conserve water.
Flooded irrigation system without proper scheduling mainly adopted in
K.C.A.E.T. Instructional farm is less efficient and causes immense water loss. In
order to compensate for this problem a study was undertaken in the K.C.A.E.T.
Instructional farm to schedule irrigation using the CROPWAT model. The crop water
requirements of eleven major crops were calculated and irrigation scheduling was
done. The total water requirement was found to be 4663.9mm.
