Optimal allocation of land and water resources to different crops play an important role for maximising the net returns out of the irrigated area. A model has been developed for allocation of land and water resources to different crops for maximisingthe net returns from an area without violating the stated constraints using linear programming technique and has been run by a software called QSB (Quantitative Systems for Business). It has been applied to the irrigation water management at Agricultural College Farm, Bapatla. Under optimal plan, it has allocated 54.3 percent and 45.7 percent of the Culturable Command Area (CCA) to paddy and cotton, respectively during Kharif season and 59.5 percent and 5 percent ot CCA to groundnut and blackgrarn resfectively during rabi season. The model has also suggested that in the event of increase in irrigation water supply, the area under paddy and groundnut should be increased during the kharif and rabi seasons, respectively.
