The study area, Kendrapara district, is located between 20° 21’ N to 20° 47’ N latitude and 86° 14’E to87° 03’ E longitude. The length of Coastline of Kendrapara district is 48 kilometer from Dhamra Muhan to Batighar. The area of district is 2,644km2.Kendrapara situated in the delta formed by Bramhani, Baitarini and branch rivers of Mahanadi. For the purpose of objective function to maximizing production paddy and jute is taken as major field crop in khraif season and paddy, wheat, groundnut, mustard, sesamum, castor blackgram, greengram, horsegram, sugarcane and potato was taken as major field crop in rabi season. The existing water resource of the study area were worked out for rabi and kharif season based on data collected from District Irrigation Division Kendrapara, CWC and CGWB Bhubaneswar. Total Surface water and Groundwater availability during rabi and kharif season 396 MCM and 1437.48 MCM respectively. An optimization model for maximizing the crop production under various formulated constraints was performed by Tora optimization system window version 2. Total water resources of the study area were 1833.49MCM. The study of optimization model shows that area of paddy was found 90,000 hectare and area of jute was found 44460 hectare that shows area of paddy get reduced up to 38,000 hectare and area of jute was increased up to 42,000 hectare. Optimal cropping pattern shows net benefit of Rs. 243.52 Crore. Similarly in rabi season area of ground nut increased up to 1580.12 hectare and area of sesamum, horse gram and sugarcane was reduced up to zero. Optimal cropping pattern in rabi season gives return of Rs. 201.58 Crore The eliminated crops by the model may be obtained as per demand by formulating new constraints.
