Abstract: The land use land cover map of Musi command area developed, it could be inferred that among the eight classes, the rice crop occupied the highest area among all crops, covering 20.1 per cent (5043 ha) of the gross command area (24, 906 ha), followed by other crops 19.7 per cent (4925 ha), plantations 7.5 per cent (1875 ha). The built up area also (22.2 %) occupied a major portion of command area (5534 ha) followed by current fallow (12.4 %) (3106 ha), Musi river coarse (sandy mass) (10.2 %) (2608 ha) and to a small extent scrub land (0.024 %) (60 ha). The overall accuracy obtained was 94.2 % with kappa’s co-efficient of 0.91. The information generated from current existing land use/ land cover map of Musi command area can serve as a guide for computing irrigation crop water requirements as per the areas occupied by agricultural crops (rice and other crops) and irrigation planning can be done by the authorities, more scientifically for better water use efficiency.
